Study Notes
Human Learning
- Knowledge acquisition involves experience, observations, and interactions with the environment.
- Key components include processing, practice, feedback, reflection, and social interaction.
- Learning is complex and often spans a lifetime.
Introduction to Machine Learning
- First introduced by Arthur Samuel in 1959 at IBM.
- Involves training data to build mathematical models for making predictions or decisions.
- ML systems improve over time by learning from historical data, predicting outcomes for new data.
Supervised Learning
- Focuses on predicting a categorical output based on input variables.
- Classification is a common method for categorical outputs with popular algorithms including Naïve Bayes, Decision Trees, and Support Vector Machines.
- Regression predicts continuous values by estimating the relationship between variables, identifying trends and important factors.
Applications of Supervised Learning
- Predicting game results based on historical data.
- Medical diagnosis using past labeled data for diseases.
- Stock and real estate pricing predictions based on historical trends.
- Text classification for categorizing emails and messages.
- Speech recognition technology.
Unsupervised Learning
- Operates without labeled data, focusing on discovering patterns and similarities within datasets.
- Clustering groups similar data points together, such as customer behavior analysis.
- Differentiates from classification by working with unlabelled datasets.
Components of Unsupervised Learning
- Clustering identifies similar patterns and groups based on attributes like size or behavior.
- Association analysis determines relationships among variables, enhancing marketing strategies (e.g., Market Basket Analysis).
Reinforcement Learning (RL)
- Involves an agent learning through interactions within an environment, often via trial and error.
- Key components include actions, states, policies, rewards, and Q-values.
- Aims to maximize cumulative rewards, adapting behaviors based on feedback and observations.
Key Features of Reinforcement Learning
- No supervisor involved; the agent learns autonomously.
- Sequential decision-making in dynamic environments.
- Time is an essential factor, influencing the learning process.
Approaches to Implement Reinforcement Learning
- Model-Based: Complete knowledge about the environment; suitable for static environments.
- Model-Free: Learning from repeated actions and outcomes in dynamic settings.
- Hybrid Approach: Combines value-based and policy-based methods for refined decision-making.
Example Algorithms in Reinforcement Learning
- Monte Carlo Tree Search (MCTS) selects and simulates moves to determine optimal actions.
- Model Predictive Control (MPC) predicts system outputs while adhering to constraints.
- Advantage Actor-Critic (A2C) algorithm uses an advantage function to measure action effectiveness in states.
