nki.language.sigmoid#

nki.language.sigmoid(x, dtype=None, mask=None, **kwargs)[source]#

Logistic sigmoid activation function on the input, element-wise.

((Similar to torch.nn.functional.sigmoid))

sigmoid(x) = 1/(1+exp(-x))

Parameters:

  • x – a tile.

  • dtype – (optional) data type to cast the output type to (see Supported Data Types for more information); if not specified, it will default to be the same as the data type of the input tile.

  • mask – (optional) a compile-time constant predicate that controls whether/how this instruction is executed (see NKI API Masking for details)

Returns:

a tile that has sigmoid of x.
