Nettet17. mar. 2016 · 2. There are minor differences in multiple logistic regression models and a softmax output. Essentially you can map an input of size d to a single output k times, or map an input of size d to k outputs a single time. However, multiple logistic regression models are confusing, and perform poorer in practice. NettetThe log-linear model is natural for Poisson, Multinomial and Product-Multinomial sampling. They are appropriate when there is no clear distinction between response and explanatory variables or when there are more than two responses. This is a fundamental difference between logistic models and log-linear models. canning smoked fish
