cauchy_¶

paddle. cauchy_ ( x, loc=0, scale=1, name=None ) [source]

Fills the tensor with numbers drawn from the Cauchy distribution.

Parameters

• x (Tensor) – the tensor will be filled, The data type is float32 or float64.

• loc (scalar, optional) – Location of the peak of the distribution. The data type is float32 or float64.

• scale (scalar, optional) – The half-width at half-maximum (HWHM). The data type is float32 or float64. Must be positive values.

• name (str, optional) – For details, please refer to Name. Generally, no setting is required. Default: None.

Returns

input tensor with numbers drawn from the Cauchy distribution.

Return type
