torch.Tensor.exponential_¶
- Tensor.exponential_(lambd=1, *, generator=None) Tensor ¶
Fills
self
tensor with elements drawn from the PDF (probability density function):\[f(x) = \lambda e^{-\lambda x}, x > 0\]Note
In probability theory, exponential distribution is supported on interval [0, \(\inf\)) (i.e., \(x >= 0\)) 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, \(\inf\)).Note that
torch.distributions.exponential.Exponential()
is supported on the interval [0, \(\inf\)) and can sample zero.
