5.4 Making Code Reproducible
Code
What we covered in this video lecture
This lecture covered some common sources of randomness that we face when training neural networks. Randomness is not necessarily a bad thing. Sometimes, a particular initial random weight configuration can lead to bad local minima, so it is recommended to train a network multiple times with different initial random weights. However, sometimes randomness can be annoying when we want to share or reproduce results — this is especially true when we are working on research papers or writing unit test. So, in this lecture, we covered some methods for reducing the sources of randomness in our neural network training code.
(Note that deterministic settings on a GPU, for example, when we work with convolutional networks later, make neural networks train a tad slower, which is whhy they are typically not used by default.)
