RmsPropConfig

Struct RmsPropConfig 

Source
pub struct RmsPropConfig {
    pub lr: f32,
    pub alpha: f32,
    pub eps: f32,
    pub weight_decay: f32,
    pub momentum: f32,
    pub centered: bool,
}
Expand description

torch.optim.RMSprop と同一の既定値。

Fields§

§lr: f32

学習率(lr)。有限かつ >= 0.0 を RmsProp::new が検証する。

§alpha: f32

二乗移動平均の減衰率(alpha)。有限かつ [0.0, 1.0) を RmsProp::new が検証する(alpha = 1.0 は square_avg が 一切更新されない退化ケースのため意図的に拒否する)。

§eps: f32

ゼロ除算防止項(eps)。sqrt(square_avg) の後に加算する (PyTorch と同順)。有限かつ > 0.0 を RmsProp::new が検証 する。

§weight_decay: f32

L2 正則化係数。PyTorch RMSprop と同じ coupled 方式(勾配へ weight_decay * param を加算してから以降の更新式へ渡す。 AdamW の decoupled 方式とは異なる)。有限かつ >= 0.0 を RmsProp::new が検証する。

§momentum: f32

モメンタム係数。> 0.0 のとき buf = momentum*buf + g/avg を経由した更新(p -= lr*buf)へ切り替わる。有限かつ >= 0.0 を RmsProp::new が検証する。

§centered: bool

centered RMSprop(avg = sqrt(square_avg - grad_avg^2))を 有効化するか。false(既定)では avg = sqrt(square_avg)。
