EcustDiff

DIY an Autodiff to challenge Fashion-MNIST

What is Fashion-MNIST

See https://github.com/zalandoresearch/fashion-mnist/blob/master/README.zh-CN.md

Data available at ./data.

(Dataset information: http://yann.lecun.com/exdb/mnist/)

What is Autodiff

See Ref2.

Implementation: See Ref3 and ./ecust_autodiff.

Test:

# sudo pip install nose
nosetests -v autodiff_test.py

How

See ./notebook/mnist.ipynb.

Conclusion

We implement a simple reverse-mode autodiff library, and run a logistic regression on Fashion-MNIST.

What's more? We can implement a CNN classifier on Fashion-MNIST via EucstAutodiff. TBD.
