torch (version 0.8.1)

distr_poisson: Creates a Poisson distribution parameterized by rate, the rate parameter.

Description

Samples are nonnegative integers, with a pmf given by $$ \mbox{rate}^{k} \frac{e^{-\mbox{rate}}}{k!} $$

Usage

distr_poisson(rate, validate_args = NULL)

Arguments

rate

(numeric, torch_tensor): the rate parameter

validate_args

whether to validate arguments or not.

m <- distr_poisson(torch_tensor(4))
m$sample()
}
