機械学習勉強会の資料です．LSTM (Long short-term memory) について理解するために，単純なニューラルネットから話を進めていきます． The document describes various probability distributions that can arise from combining Bernoulli random variables. It shows how a binomial distribution emerges from summing Bernoulli random variables, and how Poisson, normal, chi-squared, exponential, gamma, and inverse gamma distributions can approximate the binomial a
