sparsemax( logits, name=None )
Defined in tensorflow/contrib/sparsemax/python/ops/sparsemax.py
.
Computes sparsemax activations 1.
For each batch i
and class j
we have sparsemax[i, j] = max(logits[i, j] - tau(logits[i, :]), 0)
Args:
-
logits
: ATensor
. Must be one of the following types:half
,float32
,float64
. -
name
: A name for the operation (optional).
Returns:
A Tensor
. Has the same type as logits
