Project leaderboard and deadline

Some students have asked about the deadline for the class project. The deadline will be 4 weeks from now (the Monday after classes end) on 18 April.

As was mentioned in class, we put up a leaderboard where we ask you to submit the results you achieved on either project (classification scores for Dogs vs. Cats and samples or perplexity scores for the vocal synthesis task). Don’t wait until the end to do so, please put up intermediate results as well!

Final Exam

The final exam is in-class and scheduled for the last day of class, Thursday April 14, 2016, at the usual 9:30-11:30 class time.

You are not allowed to open up your phone or laptop (or any other means to connect to the internet) during the exam, but you are allowed to bring your own 8.5×11 cheat sheet (2-pager).

As a guide (but thing might be different), here are some exams from previous years.

Sequence windows

As was briefly discussed in class and mentioned on the getting started page, you will need to split up your idea in subsequences in order to train RNNs. To do so, I just added a new transformer to Fuel that does this for you (should be merged soon, but you can check out the branch or copy-paste the code if you want to use it right now).

You can use it as follows:

from fuel.datasets.youtube_audio import YouTubeAudio
from fuel.transformers.sequences import Window

data = YouTubeAudio('XqaJ2Ol5cC4')
stream = data.get_example_stream()

sequence_size = 10
windows = Window(1, sequence_size, sequence_size, True, stream)
for source, target in windows.get_epoch_iterator():
    train(source, target)
