Study Notes
Artificial Intelligence
Machine Learning
- Definition: A subset of AI that enables machines to learn from data and improve their performance on a task without being explicitly programmed.
-
Types of Machine Learning:
- Supervised Learning: The machine is trained on labeled data to learn a mapping between input and output.
- Unsupervised Learning: The machine is trained on unlabeled data to discover patterns and relationships.
- Reinforcement Learning: The machine learns by interacting with an environment and receiving rewards or penalties for its actions.
-
Machine Learning Algorithms:
- Decision Trees: A tree-based model for classification and regression tasks.
- Neural Networks: A model inspired by the structure and function of the human brain, used for tasks such as image recognition and natural language processing.
- Support Vector Machines: A model that finds the hyperplane that maximally separates classes in the feature space.
Natural Language Processing (NLP)
- Definition: A subfield of AI that deals with the interaction between computers and human language.
-
NLP Tasks:
- Tokenization: Breaking down text into individual words or tokens.
- Part-of-Speech (POS) Tagging: Identifying the grammatical category of each word (e.g., noun, verb, adjective).
- Named Entity Recognition (NER): Identifying named entities in text (e.g., people, organizations, locations).
- Sentiment Analysis: Determining the emotional tone or sentiment of text (e.g., positive, negative, neutral).
-
NLP Applications:
- Language Translation: Translating text from one language to another.
- Text Summarization: Automatically summarizing large documents or articles.
- Chatbots: Computer programs that simulate human-like conversations with users.
Artificial Intelligence
Machine Learning
- Machine learning is a subset of AI that enables machines to learn from data and improve their performance on a task without being explicitly programmed.
- There are three types of machine learning: supervised learning, unsupervised learning, and reinforcement learning.

- Unsupervised learning involves training on unlabeled data to discover patterns and relationships.
- Reinforcement learning involves learning by interacting with an environment and receiving rewards or penalties for actions.

Whole Numbers
Definition
- A whole number is a non-negative integer, including 0, without a fractional part.
- Whole numbers are also known as non-negative integers.
Properties
- Whole numbers are closed under addition and multiplication.
- The result of adding or multiplying two whole numbers is always a whole number.
- Whole numbers are not closed under subtraction, as the result can be a negative integer.
- Whole numbers are not closed under division, as the result can be a fraction.
Examples
- 0, 1, 2, 3,... are all whole numbers.
- The set of whole numbers is often denoted as W or ℤ₀₊.
Operations
- Addition: Result is always a whole number.
- Multiplication: Result is always a whole number.
- Subtraction: Result can be a negative integer or a whole number.
- Division: Result can be a fraction or a whole number.
Real-World Applications
- Counting objects: Whole numbers are used to count objects, people, or items.
- Measurement: Whole numbers are used to measure quantities, such as length, weight, or time.
- Finance: Whole numbers are used to represent amounts of money, quantities of goods, or numbers of people.
