Description: Orthogonal features in the context of machine learning refer to those variables or attributes that are independent of each other and are not correlated. This means that a change in one feature does not affect the others, allowing each to provide unique information to the model. Orthogonality is a key concept in statistics and data analysis, as it facilitates the interpretation of results and improves learning efficiency. When features are orthogonal, issues of multicollinearity, which can distort the results of predictive models, are minimized. Furthermore, orthogonality allows various machine learning algorithms, such as linear regression or decision trees, to operate more effectively, as each feature can be evaluated in isolation. In summary, orthogonal features are fundamental for building robust and accurate models in machine learning, as they ensure that each variable contributes independently to the model’s decision-making process.
