Machine Learning Algorithms - Overview

Linear Regression Type                      : Supervised Learning Target Attribute  : Continuous variable Pre-processing Remove the replace the NULL and NA values Check for Outliers and replace Divide the data into train and test data set. Check for multicollinearity. Convert the categorical variables to numeric variables Use feature selection techniques to select only the important features.                  Forward selection                  Backward selection                  Hybrid feature selection Build linear regression model (without regularization) Metrics to consider for evaluation R square value – This is the proportion of the data explained by the model Adjusted R square – This takes account of number of features RMSE – Root Mean Squared Error – This gives the root of squared difference between the actual and predicted target variable Mean Absolute Error Mean Squared Error AIC and BIC values Residual An
