I have just started the course and completed dogscats example. Just for fun, i have tried with different datasets:
Cricket and baseketball.
Initially i have taken 10 photos each in training data and 5 in validation dataset. Rest details are same as class. My accuracy comes to ~46%. I than tried with more photos in training set (~30), accuracy improved to ~53. Still not good. Further i have increased set to 50 and add some photos to valid set as well. Now my accuracy reduced to 52%.
Just one more thing, i changed the learning rate as well. For different learning rate my accuracy varied. The best i got is 70% with learning rate .003.
Any idea what should i try further to improve the accuracy?
