torch.Tensor.exponential_¶
- Tensor.exponential_(lambd=1, *, generator=None) Tensor ¶
Fills
self
tensor with elements drawn from the PDF (probability density function):Note
In probability theory, exponential distribution is supported on interval [0, ) (i.e., ) implying that zero can be sampled from the exponential distribution. However,
torch.Tensor.exponential_()
does not sample zero, which means that its actual support is the interval (0, ).Note that
torch.distributions.exponential.Exponential()
is supported on the interval [0, ) and can sample zero.
