NLP Reading Group
The Natural Language Processing reading group attempts to keep abreast of interesting research ideas and results that may be useful to us. We typically read and discuss one paper per week. All our past papers are listed below.
The reading group is listed every semester as a 1credit course, 600.765 ("Selected Topics in NLP"). Contact the instructor (Jason Eisner) to get on the mailing list. At the first course meeting, we brainstorm a bunch of topics for the semester, and vote on which ones to pursue. We then spend about 4 weeks per topic. Although some topics are within NLP, many of them explore potentially relevant work from related fields such as machine learning and linguistics.
During the summer we usually catch up on the latest NLP conference papers.
 Instructions on how to present in reading group.
 Jason's advice on how to read a paper.
 Other weekly reading groups led by CLSP faculty are the ones on semantics (Fridays), probabilistic formal languages, and machine learning (Mondays).

 Summary: There are several approaches to learning syntax in an unsupervised fashion but this paper belongs to the growing notion of exploiting multiple languages to reduce ambiguity in the learning task. The most important takehome message from the paper is, it is possible to consistently reduce the gap between supervised and unsupervised learning by progressively adding more languages to the mix. This is akin to the multiview learning results in machine learning literature. An earlier work by the same authors (EMNLP'08) showed how by carefully selecting pairs of languages in multilingual learning one can achieve better accuracies. The current paper builds on that result and shows that it is not really necessary to handpick the bilingual pairs; robust performance is guaranteed by blindly adding more languages.
 Well, not so blindly. Adding more languages to the setup means estimating more parameters in the model. Without careful implementation, such a model can become intractable. Section 3 explains in detail about the generative setup and the inference procedure. Starting with Goldwater's monolingual HMM tagging like setup for each language, the HMMs are stitched together using alignment links and latent variables called "superlingual tags" leading to a product of experts model. The superlingual tags can be considered as tags that generate similar kind of syntactic entities in each of the languages. The inference procedure as with any nontrivial npbayes setup involves computing integrals that don't have a closed form solution. Monte Carlo sampling is a standard approach to solve such problems. Gibbs sampling is one such method. The details of the sampling process is in sections 3.53.7. This part is a bit technical and will be discussed either tomorrow and/or the sessions on nonparametric bayesian methods. There are other methods one could use, like variational methods and expectation propagation instead.

 Liang Sun, Shuiwang Ji, and Jieping Ye (2008). A Least Squares formulation for Canonical Correlation Analysis. Proc. of ICML08, Helsinki
 Hotelling, in 1936, proposed a method to characterize the relationship between two variables which widely became known as "Canonical Correlation Analysis" (CCA). This involves solving the generalized eigenvalue problem of the kind Ax = \lambda Bx, which can further be reduced to the symmetric eigenvalue problem (via Cholesky decomposition) in the CCA case. It is a general interest in statistics literature to connect different statistical models to the least squares problem not only to exploit the simpler solutions for solving such problems but also to relate with other methods. The least squares formulation also allows extending the different models using the regularization framework. The least squares formulation for the CCA model involves tying together an older result showing the equivalence of CCA and the Fisher LDA, and a recent least squares formulation of multiclass LDA.
 CCA has been applied traditionally in social sciences and more recently in IR. There is literature applying CCA for problems in crosslingual IR, image retrieval, and learning lexicons. Interestingly, the ACL'08 paper by Haghighi et. al. on learning bilingual lexicons using CCA is not the first paper to do that. There is at least one paper as early as 2004 by Cancedda & friends from XRCE that does something similar and does not get cited in the ACL paper.

 This is a specialization to HMMs of the DBN version given earlier by Binder, Murphy & Russell (1997). See also section 3.7.1 of Kevin Murphy's thesis.
 Related work: This kind of trick was really pioneered by D. S. Hirschberg (1975), who cut the space requirements of longest common subsequence from quadratic all the way down to linear. Hirschberg's version can be nicely adapted to edit distance. Now, edit distance (and more generally, multiple sequence alignment) is really just a special case of shortest path in a graph. Hirschberg (1975), above, was generalized by Korf (1999)'s "Divide and Conquer Bidirectional Search, which Korf & Zhang (2000) (who discuss all these algorithms) further improved to "Divide and Conquer Frontier Search." Edelkamp & Meyer (2001) give logspace methods for improving A* search for the shortest path in a graph. (Note that A* search often fits in memory for our DP problems; reducing its memory requirements becomes paramount when we are searching trees that branch without rejoining, e.g., chess.) Bidirectional search, which is distantly related to A*, is also pretty well studied, including recent work at JHU's AMS Dept.

 ... discussing (loopy) belief propagation as background for survey propagation, a topic which has been getting more attention lately for its ability to "solve very large hard combinatorial problems, such as determining the satisfiability of Boolean formulas. Chapter 8 of Chris Bishop's textbook is supposed to be a good treatment of graphical models overall. He covers BP in section 8.4.4 after first presenting factor graphs in 8.4.3., David MacKay's treatment of BP, also in terms of factor graphs, is in chapter 26 of his book [2]. It's worth reading this chapter in full, perhaps first reading chapter 16. ... the update equations are given as (26.11) and (26.12) ... [substantial further discussion by Jason was here] Some people may prefer Bishop's style, others MacKay's.

 The edited collection that this appears in is generally interesting. Bresnan defends and develops lexicalized grammars in general; the idea of separate surface and semantic roles; and Bresnan & Kaplan's LFG in particular. You should know that she originated (in 1978) the extremely influential idea of lexicalized syntax  the idea that a grammar is simply a collection of lexical entries to be assembled in standard languageindependent ways, but that there are also "lexical redundancy rules" that relate, e.g., active and passive entries for the same verb. Some chapters address morphological and cognitive issues pertaining to lexicalization, including an essay by Pinker on lexicalist learning., Slides from Erin's presentation can be found here.
