The following equation, known as the BBP formula [1], will let you compute the nth digit of π directly without having to compute the previous digits. I've seen this claim many times, but I've never seen it explained in much detail how this formula lets you extract digits of π. First of all, this formula
GELU: Gaussian Error Linear Units | approximations
The GELU (Gaussian Error Linear Units) activation function was proposed in [1]. This function is x Φ(x) where Φ is the CDF of a standard normal random variable. As you might guess, the motivation for the function involves probability. See [1] for details. The GELU function is not too far from the more familiar ReLU,
