Study Notes
Machine Learning
- A subset of artificial intelligence that involves training machines to learn from data and make predictions or decisions without being explicitly programmed.
- Types of machine learning:
- Supervised learning: training data is labeled, and the algorithm learns to map inputs to outputs.
- Unsupervised learning: training data is unlabeled, and the algorithm learns to identify patterns or relationships.
- Reinforcement learning: algorithm learns through trial and error by interacting with an environment.
Natural Language Processing
- A subfield of artificial intelligence that focuses on the interaction between computers and humans in natural language.
- Key applications:
- Language translation
- Sentiment analysis
- Text summarization
- Chatbots
- NLP techniques:
- Tokenization: breaking down text into individual words or tokens
- Part-of-speech tagging: identifying the grammatical category of each word
- Named entity recognition: identifying and extracting specific entities such as names, locations, and organizations
Computer Vision
- A subfield of artificial intelligence that focuses on enabling computers to interpret and understand visual data from the world.
- Key applications:
- Image recognition and classification
- Object detection and tracking
- Image segmentation
- Facial recognition
- Computer vision techniques:
- Convolutional neural networks (CNNs): using neural networks to process and analyze images
- Edge detection: identifying the boundaries between objects in an image
Deep Learning
- A subset of machine learning that involves the use of neural networks with multiple layers to analyze and interpret data.
- Key applications:
- Image recognition and classification
- Speech recognition
- Natural language processing
- Game playing and decision making
- Deep learning techniques:
- Convolutional neural networks (CNNs): using neural networks to process and analyze images
- Recurrent neural networks (RNNs): using neural networks to process and analyze sequential data
Neural Networks
- A machine learning model inspired by the structure and function of the human brain.
- Key components:
- Artificial neurons: individual units that process and transmit information
- Connections: the links between artificial neurons
- Layers: the organization of artificial neurons into hierarchical structures
- Neural network types:
- Feedforward neural networks: information flows only in one direction, from input to output
- Recurrent neural networks (RNNs): information flows in a loop, allowing the network to keep track of state
