Struct MeanVarianceNormalizeLayerParams 

pub struct MeanVarianceNormalizeLayerParams {
    pub across_channels: bool,
    pub normalize_variance: bool,
    pub epsilon: f32,
}

A layer that performs mean variance normalization, along axis = -3.

.. code::

  y = MeanVarianceNormalizeLayer(x)

Requires 1 input and produces 1 output.

Input A blob with rank greater than equal to 3. Example: Rank 4 blob represents [Batch, channels, height, width] For ranks greater than 3, the leading dimensions, starting from 0 to -4 (inclusive), are all treated as batch.

Output A blob with the same shape as the input.

If acrossChannels == true normalization is performed on flattened input, i.e. the input is reshaped to (Batch,C), where “Batch” contains all dimensions from 0 to -4 (inclusive), and C contains dimensions -1, -2, -3.

If acrossChannels == false normalization is performed within a channel, across spatial dimensions (i.e. last two dimensions).

Fields

across_channels: bool

If true, mean and variance are computed across channels.

normalize_variance: bool

If false, only mean is subtracted.

epsilon: f32

A small constant to avoid division by 0 while normalizing variance. Defaults to 1e-6 if not set or set to 0.

Trait Implementations

impl PartialEq for MeanVarianceNormalizeLayerParams

fn eq(&self, other: &MeanVarianceNormalizeLayerParams) -> 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.
