Table of Contents

What is Artificial Intelligence?

Artificial Intelligence refers to the use of technologies to create machines and computer systems capable of performing tasks that typically require human intelligence. These tasks include:

Cognitive Functions: Such as reasoning, understanding language, and problem-solving.
Data Analysis: Interpreting complex data to make informed decisions.
Recommendations: Providing personalized suggestions based on user behavior.

AI is not just a single system but a collection of technologies integrated into systems to enable them to learn, reason, and act autonomously to solve complex problems. AI systems can work with various types of data, including structured, semi-structured, and unstructured data, using logic and decision trees to enhance their decision-making processes.

What is Machine Learning?

Machine Learning is a subset of Artificial Intelligence that focuses on enabling machines to learn and improve from experience without being explicitly programmed for every task. Instead of following predefined instructions, ML uses algorithms to analyze large datasets, identify patterns, and make decisions based on the insights gained.

Autonomous Learning: Machines enhance their performance by being exposed to more data over time.
Predictive Models: The output of ML algorithms, which improves in accuracy as more data is processed.

Machine Learning primarily deals with structured and semi-structured data, relying on statistical models to learn and adapt from new data inputs.
