chinakook commented on issue #7613: 1x1 convolution acceleration URL: https://github.com/apache/incubator-mxnet/pull/7613#issuecomment-325193542 @reminisce I will complete the testings. I think performance improvement and memory reduction will show up in the image detection and segmentation cases where feature maps are very big. You can refer to the tensorflow's optimization for the 1x1 conv, it's more simple and more clear than Caffe: [tensorflow conv forward](https://github.com/tensorflow/tensorflow/blob/a0d784bdd31b27e013a7eac58a86ba62e86db299/tensorflow/core/kernels/conv_ops_using_gemm.cc#L238) [tensorflow conv backward](https://github.com/tensorflow/tensorflow/blob/42ca99b5aae03a8122ba0db94abfe1f3f5c257dc/tensorflow/core/kernels/conv_grad_input_ops.cc#L666) ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
