What idea lights up in your mind when you hear the word Artificial Intelligence? Maybe robots, high-end automatic systems, or futuristic technology. You are absolutely right!

Even though AI has existed for decades, it came into the limelight just a few years ago. This is because of its ability to perform multiple tasks and resolve complex problems where humans stop. A simple example is ChatGPT; you give a prompt, and it responds to your query in seconds. All of this is possible with the power of AI models.

These AI models leverage algorithms and neural networks to interpret vast amounts of data, find patterns, and make predictions based on their learnings. Here are some statistics that showcase the importance of AI.

• Markets and Markets predicts that the AI market will grow rapidly from USD 214.6 billion in 2024 to USD 1339.1 billion by 2030, a substantial jump in market value. 
• According to Salesforce, 67% of desk workers believe AI will allow them to obtain better returns on their tech investments. 

So, whether you are a business owner, tech enthusiast, or anyone interested in investing their time and resources in ML AI development services, you should understand AI models.

To simplify your task, we will look at what are AI models, the types of AI models, how they work, and more here.

So, let’s dive in.

What is an AI model?

Generally, An AI model is like a computer program that learns from data to derive conclusions or perform specific tasks. Using algorithms and mathematics, it analyzes datasets, makes predictions, recognizes patterns, and generates content. 

An AI model improves accuracy and performance by understanding from vast data. AI models drive virtual assistants, recommendation systems, self-driving cars, predictive modeling, robotics, etc. 

You can even consider AI a digital brain that can learn from experience. Just like you identify a dog by looking at multiple examples, AI needs training to detect objects, understand language, and craft a beautiful picture by analyzing vast samples. 

Therefore, humans need to assist AI models in understanding data and performing tasks beyond training. AI models can do almost anything, from simple automated responses to complex problem-solving.

In the early 1950s, checkers and chess-playing programs were among the first successful AI models. Unlike pre-scripted moves, these AI models were capable of responding directly to the human opponent. 

Different types of AI models are suited to specific tasks or domains, and their particular decision-making logic is most useful or relevant. Let’s look at some of the types of AI models. 

But before that, it’s crucial to understand the difference between artificial intelligence, machine learning, and deep learning and how they work.

Are AI Models Different from ML and DL?

Whenever we talk about AI models, we often hear the terms machine learning and deep learning models. However, AI models are different from these models even though there is significant overlap among them. All three are more or less the powerhouse behind modern-day technological innovation. Therefore, it’s crucial to understand how these terms differ from each other.

As we have already talked about AI models, now we will talk about ML and DL.

Machine Learning

Machine learning is a branch or a subset of artificial intelligence that leverages mathematical formulae, i.e., algorithms and datasets, to learn from the past, just like humans, to make decisions and future predictions and improve with time. This is referred to as unsupervised learning. However, you can also modify the algorithms by inserting some data, also known as supervised learning. 

The ML models utilize different methods, such as decision trees, random forests, linear regression, and logistic regression, to reach conclusions or predictions. 

Example: Spotify and Netflix use machine learning algorithms to analyze users’ choices and provide music, TV Shows, and movie recommendations, respectively. 

Deep Learning

Deep Learning is a subset of machine learning, which is also a subset of AI. It tries to mimic human behavior and intelligence, leveraging a multi-layer neural network. 

Here, each layer of the network has some interconnected nodes.

The model identifies patterns and relationships from the massive amount of complex and unstructured data in the form of pictures, text, sounds, etc., present in these neural networks. 

It then generates accurate insights and predictions. Hence, deep learning models are widely used in image and video recognition, predictive analysis, speech recognition, etc.

Example: Google Photos uses deep learning to find and retrieve images based on faces, objects, and scenes.

As such, both ML and DL are essential AI technologies that enable the development of intelligent systems and the automation of processes. AI has also been taken to a new level with data-driven learning, referred to as “Smarter AI.”

How do AI Models Work?

AI models leverage multiple algorithms to understand patterns and trends in the data. Based on their understanding, they make predictions and decisions and generate output.

Here, multiple algorithms working together are referred to as a model. However, many people use “model” and “algorithm” in place of each other, which is not correct.

An algorithm can work on its own. However, an AI model relies on algorithms to function at its best. 

There are a vast number of AI models available in the industry. However, neural networks are the most well-known and best way to familiarize yourself with how AI models work.

In general, developers train the AI models using artificial neural networks to ensure that they mimic the human brain via the neurons. Here, neurons are referred to as layers. These neural networks operate using a three-layer structure:

Input Layer

The input layer is the initial layer in the AI model, which acts as an entrance door for the raw data. Every node in the layer comprises features or attributes of the input data. For instance, in image recognition, every pixel in a photo is connected with one or the other node. The primary purpose of the input layer is to receive and normalize data obtained in any format and pass it to the next layer for processing.

Hidden Layer 

The hidden layer lies between the input and output layers. This layer processes and learns from the input data. The layer comprises one or more nodes that apply mathematical transformations to gain insights about patterns or features in the data. These mathematical functions include weighted sums to understand the weights of inputs and activation functions to introduce non-linearity. 

At the time of training, AI models adjust weights between various nodes to reduce errors. The total number of layers or nodes in an AI model depends closely on the task. This simplified structure enables AI to divide big problems into smaller sets to reduce errors.  

In simple words, the hidden layer acts as the heart of the model, ensuring that the information is learned and made sense of prior to being sent to the output layer. 

Output Layer  

The output layer is the last layer in the AI model solely responsible for delivering responses to the input data. Every node in this layer matches a specific output or category. The output layer processes all the information obtained from the previous layers to provide output in a specific format, such as classification, prediction, or generated output. 

The total number of nodes in the output layer depends on the task complexity. For example, binary classification requires only one node, while multiclass problems require many nodes.

In the end, these layers work together as a solid framework that enables the model AI to learn, adapt, and make effective decisions based on the available data.

Types of AI Models

Diverse industries use different types of AI models in the tech-driven world. It’s time to adapt model AI for your business to streamline operations, offer better user experiences, and drive sales.

Here are some of the most common types of AI modes. You can choose the one most suitable for your business requirements and goals.

Let’s start.

1. Large Language Models

LLMs is a type of deep learning method that understands and interprets a language to generate text and communicate just like a real human. These models rely heavily on natural language processing and are divided into two branches. 

Both work in parallel to ensure AI models respond like humans. They are primarily trained on massive data sets to perform numerous tasks, such as language translation, generating human-like responses, summarizing documents, answering questions, predicting the next word in a sentence or phrase, and more. 

Various organizations worldwide use LLMs for different purposes. For example, businesses leverage LLMs as chatbots to understand customer sentiment and emotion, respond to queries, and increase user engagement. Businesses can also analyze multiple platforms (social media, reviews, and customer interactions) to understand users’ perceptions of a brand and enhance products or services accordingly. 

2. Foundation Models

Foundational models are an excellent base for multiple AI applications. These are primarily machine learning models pre-trained on massive datasets using neural networks to perform a particular set of tasks, thus saving time and resources. The process is well-known as “Self-supervised learning.”

For instance, ChatGPT- 4 and Google Gemini are some of the best AI tools that utilize foundational models.

These foundational models are vastly leveraged in multiple fields, such as computer vision and natural language processing. Various businesses, organizations, and people worldwide leverage a single foundational model for numerous tasks, such as classification, object detection, and even generating image captions.

3. Linear Regression Models

Linear regression is a type of AI model heavily used by data scientists for statistics. This model is specially introduced to find the relationship between the input and the output variable. It predicts the value of the output (dependable variable) considering the value of the input (independent variable). 

As it is straightforward and interpretable, it works well for scenarios where a linear relationship is expected.

Famous for continuous predictions, businesses and organizations use this model for predictive analysis and forecasting. For instance, the model helps you to identify house prices based on dependent variables like square foot. 

Besides this, the model works well for financial risk analysis. It enables financial enthusiasts to forecast stock prices or returns depending on historical data and other influencing factors.

4. Logistic Regression Models

Logistic regression is a statistical model for binary classification problems involving one or more predictors. In simple words, the model is suitable for measuring and estimating the probability of an event occurring in two possible outcomes, such as yes or no, true or false, or spam or not spam, depending on the particular set of independent variables.

This model is ideal for fields such as medical research and finance. Medical researchers can use it to determine how specific factors influence a disease and develop accurate testing. 

The model helps financial institutions determine whether a specific transaction is fraudulent or not. Considering factors such as the location history, transaction amount, and frequency of transactions, financial institutions can leverage this model to determine whether a specific transaction on the customer’s debit or credit card is fraudulent or not.

5. Decision Trees

As the name suggests, decision trees possess a tree-like model. At their base, they are nothing but a flowchart that segments the data into a series of if-else statements that make decisions based on the previous questions and answers.

Each node in the decision tree is regarded as a feature, every branch is known as a decision, and the leaf node represents the outcomes.

Decision trees are highly intuitive and quick to interpret, so they can be utilized in multiple fields to solve regression and classification problems. These fields include customer segmentation, healthcare diagnosis, and financial health checks.

For instance, decision trees enable you to approve or deny a loan, considering various factors, such as credit score, total income, running debts, insurance, etc. Due to their visual nature, this model works well when you want absolute transparency in decision-making. 

6. Random Forests

As discussed before, a decision tree is an AI model. Consider combining many decision trees, which are known as random forests.

Random forests are responsible for breaking down a massive decision-making process into part of individual “leaves.” Here, they combine multiple decision-making trees to make an accurate and stable decision.

Each tree in the forest utilizes a random subset of features to provide a result or decision. The results from every tree are collected and averaged to arrive at a final prediction or decision. 

Random forest is an AI model that can be leveraged in multiple applications involving massive data sets, such as stock analysis, marketing analytics, fraud detection, and recommendation systems. For instance, eCommerce stores can utilize random forests to predict what customers would love to purchase next.

7. Diffusion Models

Diffusion models are responsible for adding noise to the images and then breaking them into tiny pieces to examine and discover new patterns and features. The model then uses these images as a reference for creating new and attractive AI-generated photos.

Then, the model starts reversing or denoising the images to get new combinations and patterns. 

In other words, diffusion models are a class of generative AI models that understand the process of creating data by reversing a gradual noising process. Lately, diffusion models have become well-known for various image-generation tasks.

Diffusion models are widely used by the best AI image generators in the industry right now. They can create visually appealing and natural images from simple texts or edit current images. Apart from the art, diffusion models are great for tasks like image restoration, super-resolution, and even molecular design in drug discovery

8. Neural Networks 

Neural networks are AI models inspired by the human brain. They consist of millions of neurons that act just like our brain. These neurons collaborate with each other to process vast amounts of data, recognize patterns, and make predictions. 

There are multiple types of neural networks available in the industry. Let’s understand each of them in brief.

Feedforward Neural Networks (FNNs): These models are the most basic type of neural connection, with a unidirectional information flow.

Convolutional Neural Networks (CNNs):  Best suited for image and video editing tasks. The model leverages convolutional neural networks to understand features and patterns. 

Generative Adversarial Networks (GANs): They consist of two neural networks. The generator is responsible for creating new data, while a discriminator invests time and effort into differentiating real data from generated data.  

Long Short-term Memory Networks (LSTMs): A highly dedicated RNN suitable for long-term dependencies.

Recurrent Neural Networks (RNNs): These networks are designed for sequential data and time series analysis. They process information based on its order and context. They work well for language translation.

9. Support Vector Machines (SVMs)

Support vector machines (SVMs) are among the most robust classifiers. They identify an optimal hyperplane to separate the data into two different classes. The SVMs work by increasing the distance between the line and the nearest data points in every category. Thus, they ensure it becomes super simple to differentiate between various classes. 

SVMs possess all the necessary abilities to deal with any nonlinear relationship between data. In simple words, this means they can easily find out complex patterns from the data.

SVMs are often utilized more in the biometrics industry. They enable you to determine a person’s face, voice, fingerprint, etc., depending on their physical and physiological attributes.

10. Multimodal Models

Multimodal models or Multimodal AI are built to process and understand information from different modalities, such as text, images, and audio. Learning from vast datasets enables them to provide more precise answers, predictions, and decision-making.

These models can be leveraged in many industries. For instance, self-driving cars utilize a combination of visuals and sensors for quick navigation and safety. The model also allows healthcare professionals to integrate various types of patient data and make decisions.

Key Components of AI Models 

Getting familiar with the key components of the AI Models is necessary for anyone who wants to leverage them for their daily operations and offer a better user experience. Here are some of the most essential components of AI models. 

1. Data

It is the backbone of the AI model. The data can be available in any form, whether text, images, videos, or anything else, but it needs to be high-quality and reliable. More diverse and high-quality data mainly leads to enhanced model efficiency.

2. Algorithms

These are the mathematical equations or the processes that define how the model learns and processes the data. Different algorithms serve different purposes, such as classification, regression, and testing. It’s your turn to choose an algorithm that aligns with your needs.

3. Training

The AI model learns everything from the data, recognizes patterns, and makes predictions accordingly.

4. Parameters

These are the adjustable elements in the AI model leveraged at the time of training. The main purpose of these parameters is to fine-tune the model’s performance and make better predictions.

5. Interface Engine

This component is responsible for the AI model’s interaction with external systems. It simplifies the data input and output, thus ensuring the model works well in real-world situations.

How to Choose an AI Model for Your Project?

The selection of a suitable AI model can be the reason behind the success or failure of a project. Here are some key factors you shouldn’t miss by any chance for the same.

1. Problem Classification

The first and foremost thing you should do is categorize the problem you want to resolve. Here, it is suggested to work on problem categorization considering the input and the output. Why? It helps you to determine the suitable AI model for your project.

If your data is labeled well and you are sorting things out, it falls under supervised learning. If the data is not labeled and your goal is to identify various patterns and structures, it falls into unsupervised learning. 

Planning to optimize the interactions present in the environment is known as reinforcement learning. If the model predicts numerical values or deals with data classes, it refers to regression and classification problems.

The primary purpose behind defining the end goal is to choose the most suitable AI model. Hence, as soon as you have figured out your problem, it’s time to choose the most suitable AI model that will help you resolve the same.

2. Availability of the Data 

Data Quantity: Be clear about your total amount of data, as it will directly impact the model’s ability to learn patterns and generate output. The selection of the model depends on the quantity of data. Deep learning requires datasets to perform optimally. However, if data is not enough, a simpler model AI would be enough.

Data Quality: High-quality data is a necessity for any AI model. If the data you have in hand has missing values, inconsistencies, or biases, it results in false AI model training and, ultimately, wrong predictions or outputs. Therefore, it is recommended to invest in data cleaning and validation.

Data Labeling: Different machine learning models have diverse requirements. In the case of the supervised learning model, labeled data is needed, which is quite expensive. If your data is not labeled, you can opt for the unsupervised learning or semi-supervised learning model; however, it might give proper results if the data is noisy. Therefore, it is crucial to understand the problem thoroughly along with the data requirements and then choose an AI model accordingly.

3. Model Performance 

When choosing an AI model, the utmost importance should be given to its performance. Always choose an algorithm that helps you improve your project’s performance. There are different metrics to identify the performance of the model. 

These metrics include accuracy, precision, recall, and F1 score. It is essential to choose a metric that considers the problem that you want to resolve. 

4. Model Complexity

The complexity of a model has a direct relationship with how it solves a problem. If the model is complex, it can resolve various patterns within the data. However, it comes with its own set of challenges associated with maintenance and interpretability.

Here is a simple yet effective note: the complexity and interoperability of an AI model are inversely related. The more complicated an AI model, the longer it takes for interpretation. Plus, it can break your bank.

What’s the solution? It’s so simple! Analyze whether your business can reap the benefits of the AI model in the long run in terms of performance and costs. If yes, then go with a complex AI model. If not, then choose a simplified AI model.

5. Analyze Feature Dimensionality

Dimensionality is yet another crucial factor that you shouldn’t miss by any chance when choosing an AI model. 

In general, an AI model comprises two dimensions: vertical and horizontal. The vertical dimension represents the data quantity, which we have already discussed, while the horizontal dimension indicates the total number of features.

As of now, you might consider including more features in your AI model, as it helps you remove wider queries. However, it also has a negative impact. What? It increases the model’s complexity. This is when the “curse of dimensionality” phenomenon comes into play. 

It states that not every high-dimensional dataset can resolve complex problems. Therefore, it’s not always a good idea to give value to features by keeping performance and complexity at bay. In short, finding a perfect balance between the feature and the complexity is needed.

Consider implementing some well-known feature selection methods, such as filter, wrapper, and embedded, which are beneficial for keeping the most essential features. You can also leverage an algorithm like Principal Component Analysis (PCA) to reduce the dimensions. 

6. Training Duration and Expenses

When choosing an AI model, take a look at their training time and amount of expenses. The duration and expenses depend solely on the model. A deep learning model requires considerable time and cost for training as compared with a traditional AI model. 

The selection of the AI model depends on what you want to achieve. If you want an AI model to deliver accurate results, be ready for significant investment. If your goal is not to achieve that much accuracy, consider using an AI model that serves your purpose. 

In the end, the rule of thumb is to choose an AI model that helps you achieve your business goals. 

7. Speed of the AI model

Inference speed is the total amount of time an AI model takes to process the data and make predictions. When choosing any AI model, please answer this question: how quick is the model in terms of processing data and generating output? This question lets you determine the inference speed of an AI model.

Some AI models, like decision trees, linear models, etc., are well-known for quick outputs. This kind of model is best suited for self-driving cars, which need to make real-time decisions for navigation and safety.

However, neural networks and KNN (K-Nearest Neighbors) models are slow to interpret data and make predictions. 

Therefore, you should choose an AI model considering your project requirements and goals.

How to Build and Train an AI model?

Here are the simple steps that you should consider when building and training your AI model.

1. Define the Problem

Begin the process by defining the problem you want to solve with the help of your AI model, whether it’s classification, regression, recommendation, or anything else. In addition, make a list of all the challenges that you might come across during the entire process. 

Defining these things, in the beginning, ensures that your AI model development process is super smooth and ultimately builds a model that resonates well with your business goals. Partnering with an AI consulting firm will help you clarify all your doubts and make a strategic decision.

2. Data Collection

Data is the most essential thing in any AI model. Here, your goal is to collect datasets that represent the accurate, relevant, and representative nature of real-world scenarios. 

You can collect these from any of the running datasets, public datasets, or data obtained from the sensors, surveys, and more. By obtaining high-quality data, there is a high possibility that your model performs at its best.

3. Preprocess the Data

Data preprocessing is the method of cleaning, organizing, and transforming the collected data into a format that the machine can easily interpret and move forward. 

Start cleaning the data by removing any noise, redundant or irrelevant data. Focus on normalization, transforming the numerical values into a standard range (e.g., 0 to 1) to enhance the convergence at the time of training. 

Besides this, consider implementing the method known as one-hot encoding. It converts the categorical values into numerical values to ensure the AI model understands it quickly.

4. Design an AI Model Architecture

To design an AI model architecture, you first need an AI model. So, it’s time to choose an AI model according to your problem type—for instance, neural networks for deep learning, decision trees for classification, and more.  

Apart from choosing the right AI model, it’s time to design an architecture. For the same, consider adding different layers, functions, and components that match well with the AI model. This architecture has a significant impact on the performance of the AI model, so consider experimenting with diverse configurations until you come up with the most suitable one.

5. Split the Data

After you have designed the AI model architecture, it’s time to divide the datasets into three sets, as given below.

Training Set: It has a huge proportion, around 70-80%, depending on the problem and the dataset size. It is used to train the AI model so that it can learn and understand the patterns in data. The model makes necessary modifications in the elements to reduce errors in the set. In addition, it showcases the total data distribution in the AI model for quick and effective learning.

Validation Set: It comprises mainly 15% of the overall dataset and is utilized for fine-tuning the AI model and choosing the best hyperparameters. As soon as the process of training AI models is completed, they are accessed based on their performance in the validation set.

Testing Set: It also makes up to 10-15% of the overall datasets. The main goal here is to provide an unbiased evaluation of the model after it is trained and fine-tuned.

6. Decide the AI Model Training Process 

There are many ways to train your AI model. Here, we will walk you through some of the best AI model training processes. 

• Supervised Learning

This learning model requires human expertise to label training data. Here, the input data is paired with the correct output label. The primary purpose of the model with this process should be to understand the relationship between the input features and connected output labels. This helps the model make predictions. This approach is mainly utilized for tasks that require classification and regression. 

For instance, it works well for credit card fraud detection and categorizing medical images.

• Unsupervised Learning

Unlike Supervised Learning Models, Unsupervised learning models don’t work with data that has labels or predefined outcomes. Here, the AI model explores the data and finds hidden patterns or groupings without prior knowledge of what to look for. By detecting patterns in datasets, these algorithms cluster data points into groups and inform predictions. Amazon and other e-commerce companies use unsupervised association models to power their recommendation engines. 

As a result, unsupervised learning requires no labeling and does not assume there are “right” or “wrong” answers. This approach works for exploratory data analysis, anomaly detection, and more.

• Reinforced Learning

Reinforcement Learning is such an approach in which an agent interacts with an environment and understands how to make decisions by obtaining various rewards or penalties. The agent looks after a wide range of actions to grow rewards progressively. 

In simple words, reinforcement learning models are not provided with rules; they learn through trial and error. This training process is excellent for problems that require sequential decision-making, such as game playing, social media suggestions, algorithmic stock trading, and even autonomous vehicles.

• Image Annotation

Image annotation is a process of labeling or tagging various objects, regions, or features present in the image for the sake of offering information to the computer vision model. 

Generally, some popular image annotation tools, text, or a combination of both are utilized to add features to the images. These annotations include bounding boxes, segmentation marks, or keywords. They further help AI models recognize and interpret things in the images instantly. 

The image annotation training process is widely useful where object detection, facial recognition, and image segmentation are required.

7. Train AI Model

Training your AI model is essential to ensure it works in a certain manner. It’s your time to start feeding the training data into the model and then leveraging backpropagation to correct errors and make incremental modifications to the internal parameters. This stage will lead to high-end computational resources along with the usage of popular frameworks, such as TensorFlow, PyTorch, or scikit-learn, which comprises pre-built models and utilities. 

8. Hyperparameters Tuning

If your AI model is straightforward, it might not be able to find the hidden data patterns, which results in underfitting. On the other hand, if the model is very complicated, it might lead to overfitting due to noise and other elements. The goal is to have a balance of overfitting and underfitting. 

To achieve this, it’s recommended that various parameters, such as batch size, learning rate, number of trees in a random forest, and more, be fine-tuned. Consider implementing some optimization techniques like grid search and random search to reach a combination of hyperparameters that delivers your desired performance.

9. Evaluate the AI Model

After the model is trained, it’s time to check its effectiveness and overall performance. For this, you should use the validation dataset. Consider metrics like accuracy, precision, recall, and F1-score to enhance your understanding and insights into the model’s performance. To ensure your model delivers the best results, consider optimizing it based on your evaluation.

10. Test and Deploy the Model

Now, it’s time to test your AI model using a testing dataset that replicates possible real-world situations. Leverage the cross-validation method to make sure your model is delivering the same performance in various types of datasets.

If the model is delivering the required performance, it’s time to consider deploying it. Depending on your needs, you can utilize an effective environment, such as a cloud service, local server, or edge device.

11. Monitor and Work on Updates

As the data patterns are changing at a speed like never before, it’s time to continuously monitor and modify your AI model. Regularly obtain feedback from the users regarding the model’s performance and check tracking metrics to know how your model is performing. Further, make necessary adjustments to ensure your model remains accurate and relevant. 

In addition, whenever new data is available, or there are some basic changes in the data patterns, consider optimizing your model to maintain potency and deliver output as required.
