expm1¶

paddle.sparse. expm1 ( x, name=None ) [source]

Calculate elementwise exp(x)-1 , requiring x to be a SparseCooTensor or SparseCsrTensor.

\[out = exp(x) - 1\]

Parameters

• x (Tensor) – The input Sparse Tensor with data type float32, float64.

• name (str, optional) – Name for the operation (optional, default is None). For more information, please refer to Name.

Returns

A Sparse Tensor with the same data type and shape as x .

Examples

import paddle

dense_x = paddle.to_tensor([-2., 0., 1.])
sparse_x = dense_x.to_sparse_coo(1)
out = paddle.sparse.expm1(sparse_x)
