Study Notes
Machine Learning
Machine learning is a subset of artificial intelligence that involves training algorithms to learn from data and make predictions or decisions without being explicitly programmed.
Types of Machine Learning:
-
Supervised Learning: The algorithm is trained on labeled data, where the correct output is already known. The goal is to make predictions on new, unseen data.
- Example: Image classification, where the algorithm is trained on labeled images to learn the features of different objects.
-
Unsupervised Learning: The algorithm is trained on unlabeled data, and the goal is to discover patterns or relationships in the data.
- Example: Clustering customers based on their buying behavior.
-
Reinforcement Learning: The algorithm learns by interacting with an environment and receiving feedback in the form of rewards or penalties.
- Example: Training a robot to navigate a maze by rewarding it for reaching the goal.
Machine Learning Algorithms:
- Linear Regression: A linear model that predicts a continuous output variable based on one or more input features.
- Decision Trees: A tree-based model that splits data into subsets based on features and makes predictions.
- Random Forest: An ensemble model that combines multiple decision trees to improve accuracy and reduce overfitting.
- Neural Networks: A model inspired by the structure of the human brain, composed of interconnected nodes (neurons) that process inputs.
- Support Vector Machines (SVMs): A model that finds the best hyperplane to separate classes in the feature space.
Key Concepts:
- Overfitting: When a model is too complex and performs well on the training data but poorly on new data.
- Underfitting: When a model is too simple and fails to capture the underlying patterns in the data.
- Bias-Variance Tradeoff: The tradeoff between the error introduced by simplifying a model (bias) and the error introduced by fitting the noise in the data (variance).
- Gradient Descent: An optimization algorithm used to minimize the loss function and find the optimal parameters for a model.
Applications:
- Image Recognition: Machine learning algorithms can be used to recognize objects, people, and scenes in images.
- Natural Language Processing (NLP): Machine learning algorithms can be used to analyze and generate human language.
- Recommendation Systems: Machine learning algorithms can be used to recommend products or services based on user behavior.
- Autonomous Systems: Machine learning algorithms can be used to control and navigate autonomous vehicles, robots, and drones.
