public class ResourceSparseApplyFtrlV2
extends Pointer

Update relevant entries in '*var' according to the Ftrl-proximal scheme. That is for rows we have grad for, we update var, accum and linear as follows: grad_with_shrinkage = grad + 2 * l2_shrinkage * var accum_new = accum + grad_with_shrinkage * grad_with_shrinkage linear += grad_with_shrinkage + (accum_new^(-lr_power) - accum^(-lr_power)) / lr * var quadratic = 1.0 / (accum_new^(lr_power) * lr) + 2 * l2 var = (sign(linear) * l1 - linear) / quadratic if |linear| > l1 else 0.0 accum = accum_new Arguments: * scope: A Scope object * var: Should be from a Variable(). * accum: Should be from a Variable(). * linear: Should be from a Variable(). * grad: The gradient. * indices: A vector of indices into the first dimension of var and accum. * lr: Scaling factor. Must be a scalar. * l1: L1 regularization. Must be a scalar. * l2: L2 shrinkage regulariation. Must be a scalar. * lr_power: Scaling factor. Must be a scalar. Optional attributes (see Attrs): * use_locking: If True, updating of the var and accum tensors will be protected by a lock; otherwise the behavior is undefined, but may exhibit less contention. Returns: * the created Operation
