WebIn these cases, such visualizations are difficult and we would rather simply find the particular model that maximizes the validation score. Scikit-Learn provides automated tools to do this in the grid search module. Here is an example of using grid search to find the optimal polynomial model. http://duoduokou.com/python/62081781962252174090.html
WebThe equation that describes any straight line is: $$ y = a*x+b $$ In this equation, y represents the score percentage, x represent the hours studied. b is where the line starts at the Y-axis, also called the Y-axis intercept and a defines if the line is going to be more towards the upper or lower part of the graph (the angle of the line), so it is called the slope of the line.
