WebSamples are binary (0 or 1). They take the value 1 with probability p and 0 with probability 1 - p. Example: >>> m = Bernoulli(torch.tensor( [0.3])) >>> m.sample() # 30% chance 1; 70% chance 0 tensor ( [ 0.]) Parameters: probs ( Number, Tensor) – the probability of sampling 1 logits ( Number, Tensor) – the log-odds of sampling 1 WebDec 28, 2024 · The Cauchy distribution can be seen as arising from a process that is not at all esoteric — a simple act of drawing angles from a uniform distribution. Yet, it has no mean and variance and thus sample means are wildly fluctuating as is evident from the histograms above.
