The Data Science Lunch Seminar Series is an informal weekly gathering of NYU Data Science affiliated persons to discuss data science related topics. Each week there is a 30 minute presentation, over lunch (provided), with additional time for conversation and questions. The series meets Wednesdays from 12:30-1:30 PM at the Center for Data Science.

December 1st
Pablo BarberaPhD Candidate in Politics
Topic: How Social Media Reduces Mass Political Polarization: 
Using a new method to estimate the ideological positions of social media users and their communication networks over time, I provide evidence that exposure to dissonant political messages on social media induces political moderation. For the paper, click here.

December 9th

Topic: Fast Algorithms for Gaussian Processes

February 5th

Topic: Quantifying Feedforward Control: A Linear Scaling Model for Fingertip Forces and Object Weight
In this paper, we fit a linear growth curve to the biomechanical data of grasping  in order to understand the relationship between fingertip forces and object weight among healthy subjects. Our results show evidence of feedforward control during the grasping task when healthy subject grasp/lift an object with familiar weights.

Topic: Network Analysis and Nonparametric Statistics
Networks are ubiquitous in today’s world.  Any time we make observations about people, places, or things and the interactions between them, we have a network.  Yet a quantitative understanding of real-world networks is in its infancy, and must be based on strong theoretical and methodological foundations.  The goal of this talk is to provide some insight into these foundations from the perspective of nonparametric statistics, in particular how trade-offs between model complexity and parsimony can be balanced to yield practical algorithms with provable properties.

Topic: Progressive Analytics: A New Programming Paradigm for Large-Scale Data Exploration

September 21st
Kyunghyun ChoAssistant Professor, Computer Science and Data Science
Topic: Lost in Interpretability
I hear from non-ML as well as ML researchers once a while that they find it difficult to work with neural networks due to the lack of interpretability compared to other simpler models which are in many cases some variants of linear models. This has always made me wonder if there is a natural tradeoff between interpretability and modelling accuracy. In this talk, however, I argue that no such tradeoff exists, which has been argued already more than a decade ago by Breiman (2001). Furthermore, I present some recent results from deep learning showing that seemingly complex models, such as deep neural nets and recurrent neural nets, are in fact interpretable, if we try hard enough.
