mindspore.ops.glu

mindspore.ops.glu(x, axis=- 1)[source]

Computes GLU (Gated Linear Unit activation function) of input tensors.

\[{GLU}(a, b)= a \otimes \sigma(b)\]

where \(a\) is the first half of the input matrices and \(b\) is the second half.

Here \(\sigma\) is the sigmoid function, and \(\otimes\) is the Hadamard product. See Language Modeling with Gated Convluational Networks.

Parameters

x (Tensor) – Tensor to be splited. Its dtype is Number, and shape is \((\ast_1, N, \ast_2)\) where * means, any number of additional dimensions.
axis (int, optional) – the axis to split the input. It must be int. Default: -1 , the last axis of x.

Returns

Tensor, the same dtype as the x, with the shape \((\ast_1, M, \ast_2)\) where \(M=N/2\).

Raises

TypeError – If dtype of x is not Number.
TypeError – If x is not a Tensor.
