Lesson 13 graph axes

On Lesson 13 Convolutions, there are a number of graphs that I would like to know what are the axes used:

Questions:

  1. In the graphs below, is the x-axis the layer number, with zero being the first layer and 750 the output layer?

My knowledge is still patchy, and clarifying things like these will help solidify it.

Thank you!

The X axis are the mini-batch number.

There are N (=60,000 for MNIST) / bs (=64 or 512 for this example) number of mini-batches or number of times the model is utilized for each epoch
So the total range of X = (Total number of Epochs) * (N / bs or number of mini-batches)

For the top graph, bs = 64: (1) * (60,000 / 64) = 937
For the bottom graph, bs = 512: (1) * (60,000 / 512) = 117

@meanpenguin I see now, thanks again! :slight_smile:
