mindspore.ops.csr_softsign

mindspore.ops.csr_softsign(x: CSRTensor)[source]

Softsign activation function.

The function is shown as follows:

\[\text{SoftSign}(x) = \frac{x}{1 + |x|}\]

Parameters

x (CSRTensor) – Input CSRTensor, with float16 or float32 data type.

Returns

CSRTensor, with the same type and shape as the x.

Raises

TypeError – If x is not a CSRTensor.
TypeError – If dtype of x is neither float16 nor float32.

Supported Platforms:: Ascend GPU CPU

Examples

>>> indptr = Tensor([0, 1, 2, 2], dtype=mstype.int32)
>>> indices = Tensor([3, 0], dtype=mstype.int32)
>>> values = Tensor([-1, 2], dtype=mstype.float32)
>>> shape = (3, 4)
>>> x = CSRTensor(indptr, indices, values, shape)
>>> output = ops.csr_softsign(x)
>>> print(output.values)
