WebMay 24, 2024 · @morganmcg1 the purpose of L2 regularization is to "spread out" the weights in dot products, ensuring that more "independent measurements" (dimensions of the input) get used more equally, instead of any one feature dominating the computation. WebD-HCNN uses HOG feature images, L2 weight regularization, dropout and batch normalization to improve the performance. We discuss the advantages and principles of D-HCNN in detail and conduct experimental evaluations on two public datasets, AUC Distracted Driver (AUCD2) and State Farm Distracted Driver Detection (SFD3). WebMar 26, 2024 · L2 normalization can be useful when you want to force learned embeddings to lie on a sphere or something like that, but I'm not sure this function is intended for use in a data preprocessing scenario like you describe.
