Remarks

For Beginners: This scheduler follows a cosine curve, providing smooth progression that starts slow, accelerates in the middle, and slows down again near the end. This can help with convergence stability.

Progression Pattern:

fraction = 0.5 * (1 - cos(π * progress))

Constructors

CosineScheduler(int, T?, T?)

Initializes a new instance of the CosineScheduler<T> class.

public CosineScheduler(int totalEpochs, T? minFraction = default, T? maxFraction = default)

Parameters

totalEpochs int

Total number of training epochs.

minFraction T

Initial data fraction (default 0.1).

maxFraction T

Final data fraction (default 1.0).

Properties

Methods

GetDataFraction()

Gets the current data fraction using cosine annealing.
