negative

→Tensor

negative(x: Tensor)

Element-wise negation.

Verbose alias of lucid.neg. Equivalent to the unary - operator on a tensor.

xTensor

Input tensor. Any numeric dtype.

Tensor

Tensor of the same shape and dtype as x whose entries are $-x_i$ .

Mathematical definition:

\text{out}_i = -x_i

The gradient with respect to x is $-1$ everywhere.

>>> import lucid
>>> x = lucid.tensor([1.0, -2.0, 3.5])
>>> lucid.negative(x)
Tensor([-1.,  2., -3.5])
