我的理解,首先由于任务需要,softmax后必接argmax。argmax无法求导,因此引入重参数化操作求导。 此外,由于softmax仍是强者恒强的操作,argmax无法采样到logits较低的sample,为了引入随机性,使得argmax采样到各sample的概率符合原softmax的概率分布,在softmax中加入随机采样的gumbel噪声,使得logits较低的sample也有机会被ar...
Hence, a test statistic is proposed here for detection of a pair of upper and lower outliers from a Gumbel distribution with known scale parameter. The critical values of the statistic are obtained and some examples are also given to highlight the use of the statistic. The advantage of the ...
A procedure is presented for finding maximum likelihood estimates for the four parameters of a mixture of two Gumbel distributions, using classified and unclassified observations. A nonlinear discriminant function for a mixture of two Gumbel distributions is derived and estimated based on small sample ...
A weakening of the common conditions to a set of theorems concerning strong approximations of quantile processes is investigated, when the limiting extreme value distribution is the Gumbel’s law. Two results based on B.V. Gnedenko’s and R.V. Mises’s works are given.Nikos Papoutsis...
