Ema weight decay

Web具体地，EMA的超参decay一般设为接近1的数，从而保证每次EMA_weights的更新都很稳定。每batch更新流程为： Weights=Weights+LR*Grad； （模型正常的梯度下降） EMA_weights=EMA_weights*decay+(1-decay)*Weights； （根据新weight更新EMA_weights） WebOct 20, 2024 · The exponential moving average (EMA) is a weighted average of recent period's prices. It uses an exponentially decreasing weight from each previous price/period. In other words, the formula gives recent prices more weight than past prices. For example, a four-period EMA has prices of 1.5554, 1.5555, 1.5558, and 1.5560.
