decision trees, support vector regression) that can model even more intricate relationships between features and the target variable. Decision Trees: These work by asking a series of yes/no questions based on data features to classify data points. A significant drop suggests that feature is important. accuracy).

Decision Trees Decision trees recursively partition data into subsets based on the most significant attribute values. Python’s Scikit-learn provides easy-to-use interfaces for constructing decision tree classifiers and regressors, enabling intuitive model visualisation and interpretation.

Clustering and dimensionality reduction are common tasks in unSupervised Learning. For example, clustering algorithms can group customers by purchasing behaviour, even if the group labels are not predefined. Decision trees are easy to interpret but prone to overfitting. Different algorithms are suited to different tasks.

Techniques like linear regression, time series analysis, and decision trees are examples of predictive models. These models do not rely on predefined labels; instead, they discover the inherent structure in the data by identifying clusters based on similarities. Model selection requires balancing simplicity and performance.

This is used for tasks like clustering, dimensionality reduction, and anomaly detection. For example, clustering customers based on their purchase history to identify different customer segments. Reinforcement learning: This involves training an agent to make decisions in an environment to maximize a reward signal.
