what is CNN actually learning and why previous full model training didn’t work
what is the plot of layer 1?
- coefficients? weights? filters
- finding some basic shapes
what are the plots of layer 2?
- 16 filters
- each filter is good at finding one type of pattern
What are the plots of layer3?
- 12 filters
- each is more complex patterns
What are inside plots of layer4 and layer 5?
- filters to find out even more complex patterns using previous layer patterns
Which layer’s filter pattern can be improved?
- less likely for layer 1
- maybe not layer 4-5
- probably much later layers should be changed to some extent
Why the previous full model train won’t work?
- the same learning rate is applied to earlier and later layers
