What does ps mean? In dogsbreed, the ps is set to 0.2 at some point. Thanks!
It will be explained in later lessons (depending on where you are in the video).
In short, it refers to the dropout parameter. This is a parameter that helps combat overfitting by telling the learner that for certain layers, during training, it should throw away 20% of the activations.
I recommend watching the lesson (3 or 4?) where Jeremy demonstrates how NNs work in MS Excel. He also shows there how dropout works.
Thanks for the reply. I already know what dropout is, just that the name of the parameter, ps, isn’t immediately obvious to me of what it refers to.
