WebMay 28, 2024 · Previous studies proposed alternative functions to softmax de Brébisson and Vincent (); Mohassel and Zhang (); Ollivier ().The study of de Brébisson and Vincent explored spherical family functions: the spherical softmax and Taylor softmax. They showed that these functions do not outperform softmax when the length of an output vector is large. WebFor this, several probability mapping functions have been proposed and employed in literature such as softmax, sum-normalization, spherical softmax, and sparsemax, but there is very little understanding in terms how they relate with each other. Further, none of the above formulations offer an explicit control over the degree of sparsity.
