What is AI?
AI is a computer-based program that can produce responses like human beings after being trained on a large set of data.
AI learns from that data and generates completely new outcomes.
It can help us in generating text, images, and other human-like responses. AI is an umbrella term that encompasses a range of technologies, such as machine learning, deep learning, natural language processing, computer vision, and more.
These technologies enable machines to learn from data and perform tasks that previously only humans could do.
AI has many practical applications across various industries and domains, such as healthcare, finance, education, entertainment, and social goods.
AI can help us in medical diagnosis, drug discovery, credit scoring, fraud detection, language translation, image recognition, chatbots, and more.
AI can be classified into two main categories: Narrow AI and General AI.
Narrow AI
Also known as weak AI or applied AI. It is the type of AI that can perform specific tasks or solve specific problems, usually within a limited domain or scope.
Examples of narrow AI include speech recognition, face recognition, image classification, spam filtering, self-driving cars, chess playing, etc.
General AI
Also known as strong AI or artificial general intelligence (AGI). It is the type of AI that can perform any intellectual task that a human can do, across different domains and contexts.
Examples of general AI include human-like robots, virtual assistants, chatbots, etc.
General AI is still a hypothetical concept that has not been achieved yet.
AI can also be classified into two main approaches: Symbolic AI and Sub-Symbolic AI.
Symbolic AI
Symbolic AI is the approach that uses symbols and rules to represent and manipulate knowledge.
Sub-Symbolic AI
Sub-symbolic AI is the approach that uses numerical values and mathematical models to simulate neural networks and learning processes.
AI Revolution
Many AI-based language systems have been released in recent times. They are very popular among the users of this field.
The large language system of the current time is very sophisticated and easier to use than that of past systems.
Because in the past it was very difficult to provide computers to work on a large dataset of information but now it is easy.
Systems like Chat GPT-4 and the Bing search engine of Microsoft are some of the most AI-powered systems.
AI-based language systems can help us reduce the burden of many works that were first considered impossible for a computer.
They can also help us achieve our personal or professional goals, such as learning new skills, improving our writing, having fun, and more.
However, they also have some limitations and challenges, such as ethical, social, and environmental implications. Therefore, we should use them responsibly and critically.
How It Can Help Us
Today is the age of AI. Many works are being done to increase its efficiency and uses. They can help us with generation things or give us solutions and reasons for a problem.
It can help us better deal with the climate change that we are currently facing and many other problems related to the environment. We can save money and time using AI.

What Are Some Common Terms and Concepts Related to AI?
Here are some common terms and concepts related to AI that you may encounter in your study or work:
Algorithm
A set of rules or instructions that a computer or machine follows to perform a specific task or solve a specific problem.
From the set of algorithms available AI systems can make predictions after analyzing them.
Data
The raw information is used as the input or output of an algorithm or model. Data can be structured (such as tables or spreadsheets) or unstructured (such as texts or images). AI requires data for its proper working.
Data Mining
AI can find the required data through the process of data mining, which is a technique of extracting useful information and patterns from large and complex datasets.
Data mining can improve the working of an AI system by getting more knowledge through using the already existing data, such as identifying trends, anomalies, correlations, or associations.
Data mining can also help in decision-making, forecasting, and optimization.
Data Set
AI systems are first trained on a large set of data that improves their working process and knowledge.
A large group of related data is called a dataset. When required AI can search for the data set that is required and use it to produce output.
Features
A measurable attribute or characteristic of data that is used for analysis or prediction.
For example, the height and weight of a person are features that can be used to predict their health status.
Label
The output or outcome of data is used for supervised learning, which is a type of machine learning where the model learns from labeled data.
For example, the health status of a person is a label that can be predicted from their features, such as age, weight, blood pressure, etc.
Labels are also known as targets or dependent variables.
Model
