#include <training_ops.h> Mettez à jour '*var' selon le schéma Ftrl-proximal.
Résumé
accum_new = accum + grad * grad linéaire += grad - (accum_new^(-lr_power) - accum^(-lr_power)) / lr * var quadratique = 1.0 / (accum_new^(lr_power) * lr) + 2 * l2 var = (signe(linéaire) * l1 - linéaire) / quadratique si |linéaire| > l1 sinon 0,0 cumul = accum_new
Arguments :
- scope : un objet Scope
- var : doit provenir d'une variable ().
- cumul : doit provenir d'une variable ().
- linéaire : doit provenir d’une variable().
- grad : Le dégradé.
- lr : facteur d’échelle. Ça doit être un scalaire.
- l1 : régularisation L1. Ça doit être un scalaire.
- l2 : régularisation L2. Ça doit être un scalaire.
- lr_power : facteur d'échelle. Ça doit être un scalaire.
Attributs facultatifs (voir Attrs ) :
- use_locking : Si
True , la mise à jour des tenseurs var et accum sera protégée par un verrou ; sinon, le comportement n'est pas défini, mais peut présenter moins de conflits.
