Linear regression finds the mathematical equation that best describes the Y variable as a function of the X variables (features). Specifically, the interpretation of j is the expected change in y for a one-unit change in x j when the other covariates are held fixedthat is, the expected value of the You learned: The classical name Decision Tree and the more Modern name CART for the algorithm. The simplest classification algorithm is logistic regression which makes it sounds like a regression method, but its not. Lets get started with your hello world machine learning project in Python. Any value above 0.5 is considered as 1, and any point below 0.5 is considered as 0.
