Artificial Intelligence Disciplines and Techniques


Overview of Artificial Intelligence (AI)

Artificial Intelligence (AI) refers to the simulation of human intelligence in machines that are programmed to think and learn. This technology has rapidly evolved, influencing various aspects of modern life and industries.

Importance and Relevance of AI

AI’s importance lies in its ability to process vast amounts of data and perform tasks that require human intelligence, such as decision-making, speech recognition, and visual perception. Its applications span healthcare, finance, education, and beyond, making it a cornerstone of contemporary technological advancement.

AI Disciplines

Machine Learning (ML)

Definition and Overview

Machine Learning (ML) is a subset of AI that focuses on the development of algorithms that allow computers to learn from and make predictions based on data.

Types of ML (Supervised, Unsupervised, Reinforcement)
  • Supervised Learning: Involves training a model on labeled data, which means that each training example is paired with an output label.
  • Unsupervised Learning: Involves training a model on data without labeled responses and is used to find the underlying structure of the data.
  • Reinforcement Learning: Involves training an agent to make a sequence of decisions by rewarding it for good actions and penalizing it for bad ones.

Deep Learning (DL)

Definition and Overview

Deep Learning (DL) is a subset of ML that uses neural networks with many layers (deep neural networks) to model complex patterns in data.
