apeforest commented on issue #16735: Use single-bit for mask in dropout operator URL: https://github.com/apache/incubator-mxnet/pull/16735#issuecomment-572830100 @TaoLv Thanks for your review. I ran operator profining using benchmark.opperf.utils.benchmark_utils.run_performance_test. The result shows speed up in forward but some degradation in backward pass. w/ this change: ``` [{'Dropout': [{'avg_time_forward_Dropout': 1.3266, 'max_storage_mem_alloc_cpu/0': 4259.8398, 'avg_time_backward_Dropout': 0.2682, 'inputs': {'data': (1024, 1024), 'p': 0.5}}]}] ``` w/o this change: ``` [{'Dropout': [{'avg_time_forward_Dropout': 1.7864, 'max_storage_mem_alloc_cpu/0': 6291.4561, 'avg_time_backward_Dropout': 0.1836, 'inputs': {'data': (1024, 1024), 'p': 0.5}}]}] ```
