- Classification: Predicting a categorical output label (e.g. spam vs. not spam emails).
-
Training process:
- Collect and label a dataset.
- Train the algorithm on the labeled data.
- Test the algorithm on a separate dataset to evaluate its performance.
-
Examples of algorithms:
- Linear Regression
- Decision Trees
- Random Forest
- Support Vector Machines (SVMs)
Unsupervised Learning
- Definition: A type of machine learning where the algorithm is trained on unlabeled data to discover patterns or relationships.
- Goal: The algorithm learns to identify clusters, dimensions, or anomalies in the data.
-
