In this episode we briefly say what we're up to with the podcast.  No technical content, just a description of what each episode will look like, and why we're doing this.

15 - Attention and Augmented Recurrent Neural Networks

An interview with Noah Smith.

Noah tells us about his work with his students Hao Peng and Sam Thomson.  We talk about what semantic dependency parsing is, the model that they used to approach the problem, how multi-task learning fits into this with a graph-based parser, and end with a little discussion about representation learning.

22 -  Deep Multitask Learning for Semantic Dependency Parsing, with Noah Smith

ICLR 2017 paper, by Yoon Kim, Carl Denton, Luong Hoang, and Sasha Rush.

Yoon comes on to talk with us about his paper.  The paper shows how standard attentions can be seen as an expected feature count computation, and can be generalized to other kinds of expected feature counts, as long as we have efficient, differentiable algorithms for computing those marginals, like the forward-backward and inside-outside algorithms.  We talk with Yoon about how this works, the experiments they ran to test this idea, and interesting implications of their work.

Yoon also brought up a more recent paper by Yang Liu and Mirella Lapata that computes a very similar kind of structured attention, but does so much more efficiently.  That paper is here: https://www.semanticscholar.org/paper/Learning-Structured-Text-Representations-Liu-Lapata/4435c3586364e8f8a2c8c9ee671c39d7df7e196c.

26 - Structured Attention Networks, with Yoon Kim

NIPS 2016 paper by Alexander Ratner and coauthors in Chris Ré's group at Stanford, presented by Waleed.

The paper presents a method for generating labels for an unlabeled dataset by combining a number of weak labelers.  This changes the annotation effort from looking at individual examples to constructing a large number of noisy labeling heuristics, a task the authors call "data programming".  Then you learn a model that intelligently aggregates information from the weak labelers to create a weighted "supervised" training set.  We talk about this method, how it works, how it's related to ideas like co-training, and when you might want to use it.

28 - Data Programming: Creating Large Training Sets, Quickly

ACL 2017 paper, by Yusuke Oda and others (including Graham Neubig) at Nara Institute of Science and Technology (Graham is now at Carnegie Mellon University).

Graham comes on to talk to us about neural machine translation generally, and about this ACL paper in particular.  We spend the first half of the episode talking about major milestones in neural machine translation and why it is so much more effective than previous methods (spoiler: stronger language models help a lot).  We then talk about the specifics of binary code prediction, how it's related to a hierarchical or class-factored softmax, and how to make it robust to off-by-one-bit errors.
