Webb1 juni 2024 · Let’s also define Y, a Bernoulli RV with P (Y=1)=p and P (Y=0)=1-p. Y represents each independent trial that composes Z. We already derived both the variance and expected value of Y above. Using the following property E (X+Y)=E (X)+E (Y), we can derive the expected value of our Binomial RV Z: Webbtorch.bernoulli(input, *, generator=None, out=None) → Tensor. Draws binary random numbers (0 or 1) from a Bernoulli distribution. The input tensor should be a tensor containing probabilities to be used for drawing the binary random number. Hence, all values in input have to be in the range: 0 \leq \text {input}_i \leq 1 0 ≤ inputi ≤ 1.
