tensorplay.nn.functional.linear_cross_entropy(input: TensorBase, linear_weight: TensorBase, target: TensorBase, *, linear_bias=None, weight=None, reduction: [str](https://docs.python.org/3/library/stdtypes.html#str) = 'mean', ignore_index=None, label_smoothing: [float](https://docs.python.org/3/library/functions.html#float) = 0.0, options=None) → TensorBase[[source]](../_modules/tensorplay/nn/functional.html#linear_cross_entropy)

Compute cross entropy between input, transformed linearly, and
target.

Equivalent to cross_entropy(linear(input, linear_weight), target,
**kwargs) (reference path; chunked/fused options are ignored).
