RMSprop class

Implements the RMSprop optimization algorithm. Maintains a moving average of squared gradients to normalize gradient magnitudes, dividing the learning rate by the square root of recent gradient variances.

Constructors

RMSprop(List<Tensor> parameters, {required double learningRate, double beta = 0.99, double epsilon = 1e-8})

Creates an RMSprop optimizer for parameters with the given learningRate, decay factor beta, and numerical stability constant epsilon.

Properties

beta ↔ double

Exponential decay factor for the moving average of squared gradients.

getter/setter pair

epsilon ↔ double

Small constant added to the denominator to prevent division by zero.

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

step() → void

Performs a single optimization step, updating moving squared gradients and adjusting parameter values.

override

toString() → String

A string representation of this object.

inherited

zeroGrad() → void

Clears gradients by resetting the gradient buffer of every managed tensor in parameters to 0.0.
