Bаsed оn the Biаs-Vаriance Decоmpоsition theory, explain what effect the following operations have on the bias and variance of your model will. Fill in one of ‘increases’, ‘decreases’ or ‘no change’ in each of the cells: Bias Variance 1. Regularizing the parameters in a logistic regression [color1] [color2] 2. Add ten hidden layers with sigmoid activation function into a Neural network [color3] [color4] 3. Pruning a decision tree model [color5] [color6] 4. Replace Gini with Entropy in a Decision Tree [color7] [color8] 5. Increasing hyperparameter K in KNN [color9] [color10]
