Types of Artificial Intelligence: Approaches and Classifications
Artificial intelligence can be classified into different types based on different abilities and applications.
One of the most common methods of classification is to divide it into Narrow AI (or Weak AI) and General AI (or Strong AI).
Narrow AI is limited to performing specific and defined tasks and performs very well in performing these tasks.
Examples of this type of artificial intelligence include face recognition systems, voice assistants such as Siri and Alexa, and movie or music recommendation systems.
These systems are very efficient in their specialized fields, but they are not able to perform tasks outside their defined scope.

General AI, unlike Narrow AI, aims to achieve a level of intelligence that is equal to human intelligence.
A general artificial intelligence will be able to do any task that a human can do.
This type of artificial intelligence has not yet been fully realized and is one of the ambitious goals of artificial intelligence researchers.
Another classification of artificial intelligence is based on the approaches used in its development.
The two main approaches in this field are Machine Learning and Expert Systems.
Machine learning allows machines to learn from data and improve their performance without explicit programming.
Machine learning algorithms include supervised learning, unsupervised learning, and reinforcement learning.
Expert systems are built based on the knowledge of experts in a specific field and use logical rules to solve problems.
In addition, artificial intelligence can be classified based on its cognitive abilities.
Some artificial intelligence systems are capable of understanding natural language and generating text (natural language processing), while others are capable of recognizing and interpreting images (computer vision).
There are also other systems that are capable of reasoning and problem-solving (reasoning systems).
These classifications help us to better understand the diversity and complexity of artificial intelligence and better identify its various applications.
Also, artificial intelligence can be categorized based on the type of learning.
Machine Learning: Fundamentals, Algorithms, and Applications
Machine Learning is one of the main sub-branches of #Artificial_Intelligence that enables machines to learn from data and improve their performance without explicit programming.
In fact, instead of giving machines specific instructions to perform a task, machine learning algorithms allow them to identify patterns and relationships in data and use these patterns to make predictions or decisions.
Machine learning is divided into three main categories: Supervised Learning, Unsupervised Learning, and Reinforcement Learning.
In supervised learning, the machine is trained using labeled data.
This means that each data sample has a specific label or output.
The goal is for the machine to learn how to predict the correct outputs based on the inputs.
Examples of supervised learning applications include spam detection, face recognition, and stock price prediction.

In unsupervised learning, the machine is trained using unlabeled data.
In this case, the goal is for the machine to identify hidden patterns and structures in the data.
Examples of unsupervised learning applications include customer clustering, data dimensionality reduction, and anomaly detection.
In reinforcement learning, the machine is trained by interacting with an environment.
The machine takes actions in the environment and receives feedback (reward or penalty).
The goal is for the machine to learn how to take actions that yield the most reward.
Examples of reinforcement learning applications include computer games, robotics, and system control.
Machine learning algorithms are very diverse, and each is more suitable for a specific type of problem.
Some common machine learning algorithms include linear regression, logistic regression, decision tree, support vector machines, and neural networks.
The choice of the appropriate algorithm depends on the type of data, the type of problem, and the desired goals.
| Machine Learning Algorithm | Learning Type | Application |
|---|---|---|
| Linear Regression | Supervised | Predicting housing prices |
| Logistic Regression | Supervised | Spam detection |
| K-means Clustering | Unsupervised | Customer Segmentation |
Deep Neural Networks: Structure, Function, and Applications
Deep Neural Networks are one of the most advanced and powerful machine learning algorithms that are inspired by the structure of the human brain.
These networks consist of multiple layers of artificial neurons (or nodes) that are hierarchically connected.
Each neuron receives an input, applies an activation function to it, and produces an output.
The output of each neuron is sent as input to the neurons of the next layer.
Deep neural networks are capable of learning complex and abstract patterns in data, which is why they perform very well in many fields, including computer vision, natural language processing, and speech recognition.
The structure of a deep neural network usually includes an input layer, several hidden layers, and an output layer.
The input layer receives the data, and the hidden layers extract different features from the data.
The output layer produces the final prediction or decision.
The number of layers and the number of neurons in each layer depend on the complexity of the problem and the volume of training data.
One of the key features of deep neural networks is Feature Learning capability.
This means that networks can automatically identify important features of the data, and there is no need for manual feature engineering.
This feature makes deep neural networks perform better in problems with complex and unstructured data.
Deep neural networks are used in various applications.
In computer vision, they are used for face recognition, object recognition, and medical image recognition.
In natural language processing, they are used for machine translation, text summarization, and question answering.
In speech recognition, they are used to convert speech to text.
Also, deep neural networks are used in computer games, robotics, and self-driving cars.
