Understanding the difculty of training deep feedforward neural networks Xavier Glorot: Transcript


All these experimen tal results were obtained with new initialization or training mechanisms Our objective here is to understand better why standard gradient descent from random initialization is doing so poorly with deep neural networks to better u. This is intrinsically dif64257cult because of the curse of dimensionality aword sequence on which the model will be tested is likely to be different from all the word sequences seen during training Traditional but very successful approaches based on This paper shows empirically and theoretically that r andomly chosen trials are more ef64257cient for hyperparameter optimization than trials on a grid Emp irical evidence comes from a compar ison with a large previous study that used grid search an umontrealca Google Mountain View California USA bengiogooglecom Abstract Whereas theoretical work suggests that deep ar chitectures might be more ef64257cient at represent ing highlyvarying functions training deep ar chitectures was unsuccessful unti STATE of MINNESOTA WHEREAS: WHEREAS: WHEREAS: WHEREAS: More than 15,000 children in the United are diagnosed with cancer each year, a diagnosis that directly impacts their quality of life; and Dr.YoshuaBengio(e-mail:yoshua.bengio@umontreal.ca;phone:+1(514)3436804)ReferencesAvailabletoContactProfessor,Departementd'informatiqueetderechercheoperationnelle,UniversitedeMontrealP.O.Box6128, Deep Neural Networks .
