Machine Learning Introduction

Artificial Intelligence (AI) is the science that enables machines to mimic cognitive functions, such as learning, problem-solving, and decision-making, especially in non-programmed situations.

AI Problems

Reasoning and Problem Solving
Knowledge Representation (Expert Systems)
Planning
Learning (Machine Learning)
Natural Language Processing (NLP)
Perception (Vision and Speech)
Motion and Manipulation (Robotics)

What is Machine Learning?

Enables machines to learn from data
Focuses on data understanding and quality
Machine learning process: Data → Techniques → Decisions

Applications of Machine Learning

Retail
Face and Speech Recognition
Language Translation
Self-driving Cars
Virtual Personal Assistants
Traffic Predictions
Stock Marketing
Healthcare
Medical Diagnosis
Style Recommendations
Advertising Filtering/News Feed
Search
Movie Distribution
Videos
Music

Types of Machine Learning

Supervised Learning: Task-driven (Regression and Classification)
Unsupervised Learning: Data-driven (Clustering)
Reinforcement Learning: Learning by interacting with the environment

Regression

Predicting continuous values from features (e.g., Salary, Stock Price, House Prices)
Example: Predicting salary after an ML course based on degree, project quality, and other factors
Example: Predicting house prices based on recent sales in the neighborhood

Supervised Learning

Regression Problem: Given the "right answer" for each example in the data

This quiz covers the topics discussed in the first lecture of Pattern Recognition, including an introduction to Machine Learning, Simple Regression, and Linear regression with one variable. The lecture is taught by Dr. Dina Khattab from the Faculty of Computer & Information Sciences at Ain Shams University.
