EMA(Exponential Moving Average)

When training a model, it is often beneficial to maintain moving averages of the trained parameters. Evaluations that use averaged parameters sometimes produce significantly better results than the final trained values.

Create an EMA instance

ema = EMA(model,0.999)

Create shadow parameters of trainable parameters of model

ema.register()

Update the value of shadow parameters after the change of trainable parameters (This is usually used in the training loop of the model).

ema.update()

Set the parameters of the model as shadow parameters

ema.apply_shadow()

Set the parameters of the model to actual values

ema.restore()
