Study Notes
AI Overview
- AI (Artificial Intelligence) refers to the simulation of human intelligence processes by machines, particularly computer systems.
- Key components include learning, reasoning, and self-correction.
Machine Learning (ML)
- Definition: A subset of AI that enables systems to learn and improve from experience without explicit programming.
- Types of Machine Learning:
-
Supervised Learning:
- Involves labeled datasets.
- Algorithms learn to map inputs to outputs based on example input-output pairs.
- Common algorithms: Linear regression, Decision trees, Support vector machines.
-
Unsupervised Learning:
- Involves unlabeled datasets.
- Algorithms find hidden patterns or intrinsic structures.
- Common algorithms: K-means clustering, Hierarchical clustering, Principal component analysis.
-
Reinforcement Learning:
- Algorithms learn by interacting with the environment, receiving feedback in the form of rewards or penalties.
- Used in robotics, gaming, and navigation systems.
-
Supervised Learning:
- Applications: Image recognition, speech recognition, recommendation systems, fraud detection.
Natural Language Processing (NLP)
- Definition: A field of AI focused on the interaction between computers and humans through natural language.
- Key Tasks:
- Text Analysis: Understanding and interpreting the meaning of text.
- Sentiment Analysis: Determining the sentiment expressed in text (positive, negative, neutral).
- Machine Translation: Automatic translation of text from one language to another (e.g., Google Translate).
- Speech Recognition: Converting spoken language into text.
- Chatbots and Virtual Assistants: Programs that simulate conversation with users (e.g., Siri, Alexa).
- Techniques:
- Tokenization: Splitting text into individual components (words, phrases).
- Named Entity Recognition (NER): Identifying and classifying key elements in text (e.g., names, dates).
- Part-of-Speech Tagging: Assigning parts of speech to each word (nouns, verbs, adjectives).
- Challenges: Ambiguity, cultural context, slang, and evolving language.

- Speech Recognition: Converts spoken language into written text.
- Chatbots and Virtual Assistants: Simulates conversation flows, seen in applications like Siri and Alexa.
-
Techniques:
- Tokenization: The process of dividing text into individual components such as words or phrases.
- Named Entity Recognition (NER): Identifies and classifies essential elements within the text, like names and dates.
- Part-of-Speech Tagging: Assigns grammatical categories (nouns, verbs, adjectives) to words.
- Challenges: NLP encounters issues like ambiguity, cultural context, slang, and the dynamic nature of language.
