Automated SMT-based Verification for Reasoning about Approximations

Automated SMT-based Verification for Reasoning about Approximations

2 years ago
Approximate computing is an emerging area for trading off the accuracy of an application for improved performance, lower energy costs, and tolerance to unreliable hardware. However, care has to be taken to ensure that the approximations do not cause significant divergence from the reference implementation. Previous research has proposed various metrics to guarantee several relaxed […]
Inter-Active Learning with Queries on Instances and Features

Inter-Active Learning with Queries on Instances and Features

2 years ago
In this talk, I will discuss a few projects aimed at “closing the loop” for interactive natural language annotation and learning. In particular, I describe two systems that combine active and semi-supervised learning by asking humans to label both instance queries (e.g., passages of text) and feature queries (e.g., advice about words or capitalization patterns, […]
The Strange Logic of Galton-Watson Trees

The Strange Logic of Galton-Watson Trees

2 years ago
The Galton-Watson tree is a basic demographic model. The classic equation for a Galton-Watson tree being infinite has two solutions, only one of which is “correct.” What about other properties. (Example: Some node has precisely two children.) We show that when the property is what is called first order than there is a unique solution […]

Speech recognition and understanding technologies rely on supervised learning techniques which typically require tens or hundreds of hours of good quality, human annotated speech in order to train acoustic and language models. In this talk, I argue that it is worthwhile considering an alternative approach, based on unsupervised algorithms, and grounded on the study of […]
Mobile Sensor Big Data Challenges in Realizing Precision Medicine

Mobile Sensor Big Data Challenges in Realizing Precision Medicine

2 years ago
National Center of Excellence for Mobile Sensor Data-to-Knowledge (MD2K) is one of the 11 national Centers of Excellence funded by the Big Data-to-knowledge (BD2K) program of the National Institutes of Health (NIH). While other centers are addressing various aspects of biomedical big data (e.g., genomics, informatics), MD2K is leading the effort on development of big […]
Comics and Stuff: An Introduction

Comics and Stuff: An Introduction

2 years ago
The status and nature of comics are under transition, as comics move from a disposable medium to one which is perceived as having enduring value. The emergence of the so-called “graphic novel” represents a shift in how comics are published, in terms of what kind of cultural status they command, in terms of who reads […]
Bioinformatics: Local Views and Global Conclusions

Bioinformatics: Local Views and Global Conclusions

2 years ago
Graph-structured data has become a universal phenomenon in the sciences, and novel mathematics is required to tackle the problems stemming from analyzing this data. The following challenge in bioinformatics exemplifies this general class of problems: the protein Interaction graph G of an organism has one vertex for each of its proteins and an edge for […]
Extreme Classification: A New Paradigm for Ranking & Recommendation

Extreme Classification: A New Paradigm for Ranking & Recommendation

2 years ago
The objective in extreme multi-label classification is to learn a classifier that can automatically tag a data point with the most relevant subset of labels from a large label set. Extreme multi-label classification is an important research problem since not only does it enable the tackling of applications with many labels but it also allows […]
Intelligent Control of Crowdsourcing

Intelligent Control of Crowdsourcing

2 years ago
Crowd-sourcing labor markets (e.g., Amazon Mechanical Turk) are booming, because they enable rapid construction of complex workflows that seamlessly mix human computation with computer automation. Example applications range from photo tagging to audio-visual transcription and interlingual translation. Similarly, workflows on citizen science sites (e.g. GalaxyZoo) have allowed ordinary people to pool their effort and make […]
Improving Urban Public Education: Lessons from Charter Schools

Improving Urban Public Education: Lessons from Charter Schools

2 years ago
Charter schools represent one of the fastest growing, yet controversial innovations in education reform. In this talk, I will review several papers measuring urban school performance from a series of papers using data from Boston, New York City, Denver, and New Orleans from MIT’s School Effectiveness and Inequality Initiative. In addition to discussing the broader […]

President Obama recently launched the Precision Medicine Initiative, a confluence of efforts in data science, bioinformatics, systems biology and genomics. Precision medicine’s promise of “the right medicine to the right patient at the right time” is predicated on the assumption that a patient’s health data may be mapped directly to the “right medicine.” It is […]
