chainer.Summary chainer.DictSummary
A chainer.Variable
can be converted into a sparse matrix in e.g. COO (Coordinate list) format. A sparse matrix stores the same data as the original object but with a different internal representation, optimized for efficient operations on sparse data, i.e. data with many zero elements.
Following are a list of supported sparse matrix formats and utilities for converting between a chainer.Variable
and these representations.
Note
Please be aware that only certain functions accept sparse matrices as inputs, such as chainer.functions.sparse_matmul
.
