WebOct 6, 2024 · w1 is the class weight for class 1. Now, we will add the weights and see what difference will it make to the cost penalty. For the values of the weights, we will be using the class_weights=’balanced’ formula. w0= 10/ (2*1) = 5. w1= 10/ (2*9) = 0.55. Calculating the cost for the first value in the table:
