IDLmloptQuickProp

Optimization algorithms are used by neural networks to help minimize an error function by modifying the model’s internal learnable parameters. The IDLmloptQuickProp optimizer follows a quadratic approximation of the previous gradient step and the current gradient, which is expected to be close to the minimum of the loss function.

Example

Compile_opt idl2

Optimizer = IDLmloptQuickProp(0.1)

Print, Optimizer(0.1, 0.1, 0.1)

Note: Though the above is how an optimizer can be used as a standalone object, the common scenario is to pass it to the IDLmlFeedForwardNeuralNetwork::Train() method via the OPTIMIZER keyword.

Syntax

Optimizer = IDLmloptQuickProp()

Result = Optimizer(LearningRate)

Arguments

LearningRate

Specify the initial learning rate value to use as a starting point. Note that if this parameter is too small, it may lead to slow convergence, and if it is too large, it can miss the optimal solution.
