Enum ScaleMode 

pub enum ScaleMode {
    PerBatch,
    EMA {
        decay: f32,
    },
    Fixed,
}

Scale-tracking strategy for Op::FakeQuantize. Determines how the per-channel s[c] is computed each forward pass.

• PerBatch — recompute s[c] = max(|x|) / q_max from the current data on every call. Simple, no extra inputs, but noisy for activations (max-abs jumps batch-to-batch).

• EMA { decay } — keep a running s[c] in a state tensor (passed as a second op input). On each call, blend the current per-batch max-abs into the state via state' = decay·state + (1-decay)·max_abs. Smooth scale over training, makes activation-QAT actually trainable. Typical decay = 0.99.

• Fixed — never recompute. The state tensor’s value is used as-is each call (set once at construction or by the caller). Useful when scales are pre-calibrated.

Trait Implementations

impl Clone for ScaleMode

fn clone(&self) -> ScaleMode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ScaleMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for ScaleMode

fn default() -> ScaleMode

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ScaleMode

fn deserialize<__D>( __deserializer: __D, ) -> Result<ScaleMode, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for ScaleMode

fn hash<H>(&self, state: &mut H)

where H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ScaleMode

fn eq(&self, other: &ScaleMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for ScaleMode

fn partial_cmp(&self, other: &ScaleMode) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for ScaleMode

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for ScaleMode

impl Eq for ScaleMode
