Struct ActivationStats 

pub struct ActivationStats { /* private fields */ }

Incremental activation statistics for a single layer.

Tracks min, max, mean, standard deviation, and a 256-bin histogram. Supports incremental updates via Chan’s parallel algorithm.

Implementations

impl ActivationStats

pub fn min(&self) -> f32

Minimum observed value.

pub fn max(&self) -> f32

Maximum observed value.

pub fn mean(&self) -> f32

Running mean.

pub fn std(&self) -> f32

Running standard deviation.

pub fn count(&self) -> usize

Number of observations.

impl ActivationStats

pub fn from_data(data: &[f32]) -> Self

Create stats from a single batch of observations.

pub fn update(&mut self, data: &[f32])

Incrementally merge a new batch of observations into the stats.

pub fn percentile(&self, p: f32) -> f32

Estimate the value at percentile p (0–100) from the histogram.

pub fn histogram_data(&self) -> Vec<(f32, usize)>

Return histogram data as (bin_center, count) pairs.

Trait Implementations

impl Clone for ActivationStats

fn clone(&self) -> ActivationStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ActivationStats

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

Formats the value using the given formatter.

impl Default for ActivationStats

fn default() -> Self

Returns the “default value” for a type.
