L2 keras
Tīmeklis2024. gada 13. febr. · L2-regularization adds a norm penalty this loss function and as a result to each weight update. $$ \sum_{i=1}^N L\left( y_i, \; \hat y_i \right) + λ \cdot \ W\ _2^2 $$ This penalty counters the actual update, meaning that it makes the weight updates harder. This has the effect of actually increasing the output your loss function. Tīmeklis2024. gada 26. dec. · Adding regularization in keras. Regularization generally reduces the overfitting of a model, it helps the model to generalize. It penalizes the model for having more weightage. There are two types of regularization parameters:- * L1 (Lasso) * L2 (Ridge) We will consider L1 for our example.
