public class MPSNNOptimizerRMSProp
extends MPSNNOptimizer

MPSNNOptimizerRMSProp The MPSNNOptimizerRMSProp performs an RMSProp Update RMSProp is also known as root mean square propagation. s[t] = decay * s[t-1] + (1 - decay) * (g ^ 2) variable = variable - learningRate * g / (sqrt(s[t]) + epsilon) where, g is gradient of error wrt variable s[t] is weighted sum of squares of gradients API-Since: 12.0

Encode an MPSNNOptimizerRMSProp object to a command buffer to perform out of place update The following operations would be applied s[t] = decay * s[t-1] + (1 - decay) * (g ^ 2) variable = variable - learningRate * g / (sqrt(s[t]) + epsilon) where, g is gradient of error wrt variable s[t] is weighted sum of squares of gradients

Parameters:

commandBuffer - A valid MTLCommandBuffer to receive the encoded kernel.

Description copied from class: MPSKernel

NSSecureCoding compatability While the standard NSSecureCoding/NSCoding method -initWithCoder: should work, since the file can't know which device your data is allocated on, we have to guess and may guess incorrectly. To avoid that problem, use initWithCoder:device instead.

Overrides:

Parameters:

aDecoder - The NSCoder subclass with your serialized MPSKernel

device - The MTLDevice on which to make the MPSKernel

Returns:

A new MPSKernel object, or nil if failure. API-Since: 11.0
