CSCE 496/896 (Spring 2018) Hack-A-Thon 2: Defining a Model

Make-up session at 4:30 Wednesday, January 24, in Avery 119

Assigned Monday, January 22
Due Thursday, January 25 Saturday, January 27 at 11:59 p.m.

First, download the file hackathon_2.ipynb. Then, go to and log in via two-factor authentication. You then need to select "Local Jupyter Notebook" and click "Upload" to upload hackathon_2.ipynb

The MNIST data is on crane in the folder

The folder has four numpy files: mnist_test_images.npy, mnist_train_images.npy, mnist_test_labels.npy, and mnist_train_labels.npy. (These files are also zipped up in, but you should use the ones already on crane for this assignment.) The Jupyter Notebook for this hack-a-thon contains instructions for reading data from these files.

Now you should be able to step through the notebook (note that nothing in the "Coda" section is required). When done, select "File" → "Close and Halt". Then check the box next to your notebook and click "Download". Then go to handin and submit your ipynb file by 11:59pm Thursday.

If you have questions about the exercise, see this solution file.
