2018 arXiv   pre-print
On the other hand, it is reported that parameter redundancy in the weight matrix in biaffine classifiers, which has O(n^2) parameters, results in overfitting (n is the number of dimensions).  ...  In this paper, we attempted to reduce the parameter redundancy by assuming either symmetry or circularity of weight matrices.  ...  This work was supported by JSPS KAK-ENHI Grant Number JP18K11457 and JST CREST Grant Number JPMJCR1513, Japan.  ...
