# Statistics Layers¶

class AccuracyLayer

Compute and accumulate multi-class classification accuracy. The accuracy is averaged over mini-batches. If the spatial dimension is not singleton, i.e. there are multiple labels for each data instance, then the accuracy is also averaged among the spatial dimension.

bottoms

The blob names for prediction and labels (in that order).

dim

Default -2 (penultimate). Specifies the dimension to operate on.

class BinaryAccuracyLayer

Compute and accumulate binary classification accuracy. The accuracy is averaged over mini-batches. Labels can be either {0, 1} labels or {-1, +1} labels

bottoms

The blob names for prediction and labels (in that order).
