Expand description

Configuration parameters for a LossScaler.

Fields§

§policy: ScaleUpdatePolicy

Which update policy to use.

§initial_scale: f64

Starting loss scale (default 65536.0 = 2^16).

§min_scale: f64

Floor for the loss scale (default 1.0).

§max_scale: f64

Ceiling for the loss scale (default 2^24 = 16_777_216.0).

§scale_up_factor: f64

Multiplicative factor applied to the scale on a successful streak (Dynamic policy uses 2.0 to double; Gradual uses a configurable value close to 1, e.g. 1.001).

§scale_down_factor: f64

Multiplicative factor applied on overflow (should be < 1, e.g. 0.5).

§scale_up_interval: u64

Number of clean (non-overflow) steps required before a scale-up. For Dynamic this is often 2000; for Gradual it can be smaller.
