Tensor.cauchy(median=0.0, sigma=1.0)[source]

Fills the tensor with numbers drawn from the Cauchy distribution. It is defined as follows:

\[f(x)= \frac{1}{\pi} \frac{\sigma}{(x-median)^2 +\sigma^2}\]

Warning

This is an experimental API that is subject to change or deletion.

Parameters

  • median (float, optional) – the location parameter, specifying the location of the peak of the distribution. Default: 0.0.

  • sigma (float, optional) – the scale parameter which specifies the half-width at half-maximum. Default: 1.0.

Returns

Tensor. A Tensor with the same type and shape of input.

Supported Platforms:

Ascend CPU
