Study Notes
Supervised Learning
Definition
- Type of machine learning where the model is trained on labeled data, meaning the correct output is already known
- Goal is to learn a mapping between input data and output labels, so the model can make accurate predictions on new, unseen data
Types of Supervised Learning
- Regression: Predicting continuous or numerical values (e.g. predicting house prices)
- Classification: Predicting categorical or discrete values (e.g. spam vs. not spam emails)
Supervised Learning Process
- Data Collection: Gathering labeled data for training and testing
- Data Preprocessing: Cleaning, normalizing, and transforming data into a suitable format
- Model Selection: Choosing a suitable algorithm and model for the problem
- Model Training: Training the model on the labeled data
- Model Evaluation: Evaluating the model's performance on a test dataset
- Model Deployment: Deploying the trained model to make predictions on new data
Supervised Learning Algorithms
- Linear Regression: Simple and widely used algorithm for regression tasks
- Logistic Regression: Widely used algorithm for binary classification tasks
- Decision Trees: Simple and interpretable algorithm for classification and regression tasks
- Random Forests: Ensemble learning algorithm combining multiple decision trees
- Support Vector Machines (SVMs): Powerful algorithm for classification and regression tasks
- Neural Networks: Complex and powerful algorithm for classification and regression tasks
Supervised Learning Challenges
- Overfitting: When the model is too complex and performs well on training data but poorly on test data
- Underfitting: When the model is too simple and performs poorly on both training and test data
- ** Curse of Dimensionality**: When the model is affected by the high dimensionality of the data
- Imbalanced Data: When the classes in the data are not equally represented
