tf.contrib.sparsemax.sparsemax
Computes sparsemax activations 1.
tf.contrib.sparsemax.sparsemax(
logits, name=None
)
For each batch i and class j we have
$$sparsemax[i, j] = max(logits[i, j] - tau(logits[i, :]), 0)$$
| Args | |
|---|---|
logits | A Tensor. 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. |
