Machine Learning Fundamentals: Comprehensive Lecture Notes
I. Introduction to Machine Learning (Lecture 01)
Key Concepts:
- Definition:
Machine Learning (ML) is a subfield of AI that uses data-driven algorithms to recognize patterns and make decisions without explicit programming. - Why Learn ML?
- Automates tasks (e.g., image classification)
- Adapts to new data
- Provides insights from complex datasets
- Terminology:
- Training Example: An individual row (or data point) in your dataset.
- Feature: A measurable property or characteristic (e.g., pixel values, square footage).

The Great Gatsby: Setting, Symbols, and Characters
Setting: 1920s New York
The Great Gatsby is set in the summer of 1922, in and around New York City. The novel primarily takes place in three key locations:
- East Egg: Represents old money and aristocratic status (e.g., Tom and Daisy Buchanan). The people here inherited their wealth and look down on the newly rich.
- West Egg: Represents new money and self-made wealth (e.g., Gatsby). Though rich, these people lack social status and are seen as outsiders
Machine Learning Algorithms: Data Science Essentials
Data & K Nearest Neighbor
- What is Data? A collection of items & their characteristics, d features or attributes which describe d items & make them unique.
- Why is Data important? We can use data to extract useful info to detect patterns which may not be visible to the naked eye, which can then be used to make predictions or decisions.
- Input vector: list of numbers which describe an item.
- KNN is a supervised learning algorithm, meaning it learns from labeled data.
- KNN finds similarities by

a. Modeling Values as Base and Differences
On July 19th, 2011, Dell Computers offered a base Inspiron 600 for $299.99. A buyer could customize this computer. One of the choices was the type of Office 2010, where Windows 7 Home Premium was included in the base price:
- If you wanted Microsoft Office and Student 2010, add $119 (price becomes $418).
- If you wanted Microsoft Office Home and Business 2010, add $199 (price becomes

The Eyes of God
The eyes of God represent the idea that “Somebody is always watching.” The billboard is described as a pair of eyes looking through yellow spectacles. There is no face. The eyes symbolize someone always watching, the yellow rims represent the corruption of society and characters, and the lack of a face represents the hollowness of some characters.
The Green Light
First discovered by Nick when he watches Gatsby standing on his lawn, gazing at a green light emanating from the dock. The
