WebThe most popular deep learning library TensorFlow by default uses 32 bit floating point precision. The choice is made as it helps in 2 causes: Lesser memory requirements Faster calculations 64 bit is only marginally better than 32 bit as very small gradient values will also be propagated to the very earlier layers. WebComparison on using float32 instead of float64: Half the size in memory and on disk Half the memory bandwidth required (may be a bit faster in some operations)
