Support Vector Machines and Decision Trees

Support vector machines (SVMs) classify trading data by finding the optimal hyperplane separating different classes. SVMs are effective for binary classification problems, such as determining whether a stock price will rise or fall. By maximizing the margin between support vectors (data points nearest the hyperplane), SVMs enhance prediction reliability.

Decision trees, in contrast, create a tree-like model of decisions and their possible outcomes. Each node represents a decision point, splitting the data based on specific criteria (e.g., price thresholds). Decision trees are intuitive and straightforward, making them useful for feature selection and identifying critical trading signals.
