Minnesota Natural Language Processing Seminar Series: Pushing the Boundary of Unsupervised Text Generation

The Minnesota Natural Language Processing (NLP) Seminar is a venue for faculty, postdocs, students, and anyone else interested in theoretical, computational, and human-centric aspects of natural language processing to exchange ideas and foster collaboration. The talks are every other Friday from 12 p.m. - 1 p.m. during the Fall 2021 semester.

This week's speaker, Philippe Laban (Salesforce Research), will be giving a talk titled "Pushing the Boundary of Unsupervised Text Generation."

Abstract

Recent progress in automated text generation relies predominantly on the use of large datasets, sometimes requiring millions of examples for each application setting. In the first part of the talk, we'll develop novel text generation methods that balance the goals of fluency, consistency, and relevancy without requiring any training data. We focus on text summarization and simplification by directly defining a multi-component reward, and training text generators to optimize this objective. The novel approaches that we introduce perform better than all existing unsupervised approaches and in many cases outperform those that rely on large datasets, showing that high-performing NLP models are possible when little data is available.

Biography

Philippe Laban is a Research Scientist at Salesforce Research, where he works on text generation projects, including summarization and interactive question answering. Previously, he obtained his Ph.D. from UC Berkeley, where he was advised by Marti Hearst and John Canny. His work in Berkeley focused on designing unsupervised methods for text generation and on building and adapting NLP techniques to a very large, noisy and evolving news dataset. He did his undergraduate education at Georgia Tech, doing research in signal processing and discrete mathematics.

UMN Machine Learning Seminar: Probability Maximization via Minkowski Functionals: Convex Representations and Tractable Resolution

The UMN Machine Learning Seminar Series brings together faculty, students, and local industrial partners who are interested in the theoretical, computational, and applied aspects of machine learning, to pose problems, exchange ideas, and foster collaborations. The talks are every Thursday from 12 p.m. - 1 p.m. during the Fall 2021 semester.

This week's speaker, Uday V. Shanbhag (Penn State), will be giving a talk titled "Probability Maximization via Minkowski Functionals: Convex Representations and Tractable Resolution."

Abstract

In this paper, we consider the maximization of a probability P{ζ∣ζ∈K(x)} over a closed and convex set X, a special case of the chance-constrained optimization problem. We define K(x) as K(x)≜{ζ∈K∣c(x,ζ)≥0} where ζ is uniformly distributed on a convex and compact set K and c(x,ζ) is defined as either {c(x,ζ)≜1−|ζTx|m, m≥0} (Setting A) or c(x,ζ)≜Tx−ζ (Setting B). We show that in either setting, P{ζ∣ζ∈K(x)} can be expressed as the expectation of a suitably defined function F(x,ξ) with respect to an appropriately defined Gaussian density (or its variant), i.e. Ep~[F(x,ξ)]. We then develop a convex representation of the original problem requiring the minimization of g(E[F(x,ξ)]) over X where g is an appropriately defined smooth convex function. Traditional stochastic approximation schemes cannot contend with the minimization of g(E[F(⋅,ξ)]) over X, since conditionally unbiased sampled gradients are unavailable. We then develop a regularized variance-reduced stochastic approximation ({\textbf{r-VRSA}}) scheme that obviates the need for such unbiasedness by combining iterative {regularization} with variance-reduction. Notably, ({\textbf{r-VRSA}}) is characterized by both almost-sure convergence guarantees, a convergence rate of O(1/k1/2−a) in expected sub-optimality where a>0, and a sample complexity of O(1/ϵ6+δ) where δ>0.

CS&E Colloquium: Symbolic Execution as a Flexible Tool for Binary Analysis

The computer science colloquium takes place on Mondays from 11:15 a.m. - 12:15 p.m.

This week's speaker, Stephen McCamant (University of Minnesota), will be giving a talk titled "Symbolic Execution as a Flexible Tool for Binary Analysis."

Abstract

Analyzing software at the binary (machine code) level is advantageous or required in many scenarios, but it can be more challenging than source-level analysis because of the complexities of instruction sets and a lack of high-level structure. Symbolic execution is a very useful approach for building binary analyses because it encapsulates instruction-set complexity, does not require high-level structure, and serves as a foundation on which a variety of analyses can be built. I'll describe the open-source FuzzBALL system for binary symbolic execution we are developing at the University of Minnesota to discuss some design trade-offs. Then I'll briefly sketch three applications of binary symbolic execution. In test generation for security vulnerabilities, symbolic execution acts as an enhanced dynamic analysis. In enumerating the targets of jump tables, symbolic execution acts as a static analysis without conservative approximation.  And in generating tests for CPU emulators, it performs bounded-exhaustive enumeration.

Biography

Stephen McCamant is an Associate Professor of Computer Science and Engineering at the University of Minnesota, where he has been since the fall of 2012. His main research area is program analysis for software security and correctness. He is especially interested in binary code analysis and transformation, hybrid dynamic/static techniques and symbolic execution, information flow/taint analysis, and applications of decision procedures. His research on software-based fault isolation won the USENIX Security Test of Time award in 2018, and was adopted in Google's Native Client system. He received his Ph.D from the Massachusetts Institute of Technology in 2008, and from 2008-2012 he was a postdoc at UC Berkeley.

UMN Machine Learning Seminar: Machine Learning and Scientific Computing

The UMN Machine Learning Seminar Series brings together faculty, students, and local industrial partners who are interested in the theoretical, computational, and applied aspects of machine learning, to pose problems, exchange ideas, and foster collaborations. The talks are every Thursday from 12 p.m. - 1 p.m. during the Fall 2021 semester.

This week's speaker, Eric Vanden-Eijnden (New York University), will be giving a talk titled "Machine Learning and Scientific Computing."

Abstract

The recent success of machine learning suggests that neural networks may be capable of approximating high-dimensional functions with controllably small errors. As a result, they could outperform standard function interpolation methods that have been the workhorses of current numerical methods. This feat offers exciting prospects for scientific computing, as it may allow us to solve problems in high-dimension once thought intractable. At the same time, looking at the tools of machine learning through the lens of applied mathematics and numerical analysis can give new insights as to why and when neural networks can beat the curse of dimensionality. I will briefly discuss these issues, and present some applications related to solving PDE in large dimensions and sampling high-dimensional probability distributions.
