The K-Nearest Neighbours algorithm is a classification algorithm that takes a bunch of labeled points and uses them to learn how to label other points. However, there is a strong correlation between a categorical variable and other variables if the ANOVA test gives us a large F-test score and a small p-value. Ridge regression controls the magnitude of these polynomial coefficients by introducing the parameter alpha. Information models and data models are different and serve different purposes. --, correlation coefficient close to +1 or -1, F-test score: variation between sample group means divided by variation within sample group, small F implies poor correltaion between variale categories and target variable, large F implies strong correlation between variable categories and target variable, p-value: confidence degree (whether the obtained result is statistically significant), What task does the method value_counts perform?
