海外TECH	DEV Community	Prevent the Overfitting through Regularization: An example by Ridge Regression	https://dev.to/rlrocha/prevent-the-overfitting-through-regularization-an-example-by-ridge-regression-45hd	Prevent the Overfitting through Regularization An example by Ridge Regression DescriptionIn my post on Polynomial Curve Fitting was discussed that adding more examples is one of the possible ways to prevent overfitting the phenomenon that occurs in the figure above where is a gap between the training lower and validation higher errors Another approach used to control the overfitting is Regularization which involves adding a penalty term to the error function to discourage the coefficients from reaching large values how to introduce Bishop in the Pattern Recognition and Machine Learning book This post continues the polynomial curve fitting analysis but through the Regularization known as Ridge Regression instead of Linear Regression RegularizationTo apply the regularization in the previous analysis it is necessary to modify the Sum of Squares Error SSE function adding the regularization parameter λ as shown in the equation below SSE ∑n N ypred y λ∣w∣SSE frac sum n N left y pred y right frac lambda left w right SSE ​n ∑N​ ypred​ y λ​∣w∣Where w ²is equivalent to w T w and the parameter or coefficient λconducts the relative importance of the regularization term compared with the SSE term As before instead use some optimization algorithms like gradient descent it is used the adapted normal equation to obtain the coefficients w as shown below W XTX λI XTyW left X T X lambda I right X T yW XTX λI XTyWhere λis the regularization parameter I is the identity matrix of size M and M is the order of the polynomial The coefficients obtained through normal equation are given by the function below def normal equation ridge x y M L Normal equation w x x L I x y I np identity M xT x T w np dot np dot np linalg pinv np dot xT x L I xT y return w Choosing the regularization parameterTo exemplify the regularization we used the overfitted model of M which obtained a Root Mean Square Error RMSE of and in training and validation sets respectively The regularization parameter λvalues ranging from to were investigated but to better illustrate the values are displayed in terms of the natural log between ≤ln λ ≤ where the value λ exp L is input from the above function and L is the value in range The RMSE of the validation set is used to choose the parameter λ The figure below shows the analysis done to choose the parameter λ For the value ln λ in the figure above the RMSE is approximately the value without regularization as the value of λtends to zero λ exp e The best parameter found red dashed is ln λ λ exp e reaching of RMSE of validation set while the training set got The table below compares the coefficient values for ln λ ∞and ln λ Note that ln λ ∞corresponds to the model without regularization and ln λ the model that has the smallest validation error with regularization It is possible to notice that the coefficients of ln λ ∞are large while the values ln λ are smaller due to the addition of the penalty term Polynomial order with normalizationAs the post of Polynomial Curve Fitting the error analysis is performed in the training and validation sets by the order of the polynomial but now with regularization The figure below shows the training and validation RMSE by the order of the polynomial where the prevention of overfitting due to the use of regularization in each analyzed order M and is noted The complete code is available on Github and Colab Follow the blog if the post it is helpful for you Follow me on Linkedin and Github	2022-05-07 13:32:27
