Utilities¶
Convolution/Deconvolution utilities¶
Calculates output size of convolution. |
|
Calculates output size of deconvolution. |

Implementation of Walker’s alias method. |
Common utilities¶
Shows Chainer runtime information. |
Reporter¶
Object to which observed values are reported. |
|
Returns the current reporter object. |
|
Reports observed values with the current reporter object. |
|
Returns a report scope with the current reporter. |
Summary and DictSummary¶
Online summarization of a sequence of scalars. |
|
Online summarization of a sequence of dictionaries. |
Sparse utilities¶
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()
.
A sparse matrix in COO format. |
|
Returns a single or a batch of matrices in COO format. |
Experimental feature annotation¶
Declares that user is using an experimental feature. |
