TaoLv commented on issue #16735: Use single-bit for mask in dropout operator URL: https://github.com/apache/incubator-mxnet/pull/16735#issuecomment-586662412 > Why does it increase memory load? If there are N elements, per the Bernoulli distribution generation in VSL, we still need to allocation memory and write `N*4` bytes to it. To generate bit mask, we need load the `N*4` bytes back and write `N/8` bytes with bits.
