Study Notes
Machine Learning
Machine learning is a subset of artificial intelligence that involves training algorithms to make predictions or decisions based on data.
Supervised Learning
- Type of machine learning where the algorithm is trained on labeled data
- Goal is to learn a mapping between input data and output labels
- Examples: image classification, speech recognition, sentiment analysis
- Types of supervised learning:
- Regression: predicts continuous output variable
- Classification: predicts categorical output variable
Deep Learning
- Subset of machine learning that uses neural networks with multiple layers
- Inspired by structure and function of the human brain
- Can be used for both supervised and unsupervised learning
- Types of deep learning:
- Convolutional Neural Networks (CNNs): image recognition, object detection
- Recurrent Neural Networks (RNNs): sequential data, language modeling
Neural Networks
- Model composed of interconnected nodes (neurons) that process inputs
- Each node applies an activation function to the input, producing an output
- Can be used for supervised, unsupervised, and reinforcement learning
- Types of neural networks:
- Feedforward Networks: no feedback loops
- Feedback Networks: feedback loops, used for RNNs
Reinforcement Learning
- Type of machine learning where the algorithm learns through trial and error
- Goal is to maximize a reward signal by taking actions in an environment
- Examples: game playing, robotics, autonomous driving
- Key concepts:
- Agent: takes actions in the environment
- Environment: responds to the agent's actions
- Reward: feedback signal for the agent's actions
- Policy: mapping from state to action
- Value function: estimates expected reward for each state
Machine Learning
- Subset of artificial intelligence that involves training algorithms to make predictions or decisions based on data.
Supervised Learning
- Trained on labeled data to learn a mapping between input data and output labels.
- Goal is to make predictions on new, unseen data.
- Examples include image classification, speech recognition, and sentiment analysis.
- Two types of supervised learning:
- Regression: predicts continuous output variable.
- Classification: predicts categorical output variable.
