Daniela Huppenkothen, Moore-Sloan Postdoctoral Fellow at the NYU, Center for Data Science
Talk Title: Exploring the Violent Universe: Data Science for X-ray Astronomy
Abstract: X-ray astronomy, the study of the universe at very short wavelengths, helps us unravel physical laws under the most extreme conditions known: the densest stars, the brightest explosions, the strongest gravity, and magnetic fields, the hottest plasmas. The data sets that we have, taken with X-ray telescopes on board a fleet of space satellites, are abundant and diverse, and can be used to tackle some of the mysteries surrounding black holes, neutron stars, and stellar explosions. All of these types of sources are highly variable on timescales ranging from milliseconds to decades, and studying how their brightness changes with time is a prime tool to help us understand the underlying physics. In this talk, I will give a brief overview of the fundamental processes of nature we study with this kind of data, and show a few snapshots of projects on neutron stars and black holes I am working on at the CDS.
Bio: Daniela Huppenkothen is a Moore-Sloan Postdoctoral Fellow at the NYU Center for Data Science. She is primarily interested in time series methods for astronomy; so far, her work has focussed on developing methods for characterising variability in fast transient events (in particular magnetar bursts and black hole binary systems) in data from X-ray space telescopes, and on using empirical models to make inferences about the underlying physics of the system. She is also interested in machine learning and astrostatistics.

Talk Title: Julia Solves the Four Language Problem for Data Science
Abstract: Once upon a time, I was forced to write my data science projects in patchwork of four languages: Matlab, R, C and Ruby. Today, I only use one: Julia. In this talk I’ll explore the kinds of data science problems that Julia excels at, how it cooperates in beautiful harmony with C, C++ and Python, and where we’re going with the language in the future. There will be lots of live coding and some slides with fancy transitions.
Bio: Stefan is a Research Engineer at the NYU Center for Data Science. Previously, he’s worked as a data scientist, researcher and software engineer at Etsy, Citrix Online, and Akamai.

Talk Title: Should You Trust Your Money to a Robot?
Abstract: Financial markets emanate massive amounts of data from which machines can, in principle, learn to invest with minimal initial guidance from humans. I contrast human and machine strengths and weaknesses in making investment decisions. The analysis reveals areas in the investment landscape where machines are already very active and those where machines are likely to make significant inroads in the next few years.

5th Data Science Showcase
Wednesday, April 15th
Rumi Chunara, Assistant Professor in Computer Science and Engineering and the Global Institute of Public Health
Talk Title: Data Science for Improved Public Health
Abstract: Internet and mobile connectivity have enabled a plethora of new data that offer unprecedented opportunities in many domains. The real-time, quantitative and geo-located data generated through these crowdsourced sensors can improve population-public health surveillance, which suffers from limits due to latency, high cost, inherent contributor biases, and imprecise resolution. Simultaneously, the observational and informal nature of these data sources present some common and new data challenges. In this talk I will discuss a few approaches towards integrating crowdsourced data into epidemiological models, including increasing specificity, and relating the data to the underlying population at risk. I will also show how the proposed new data sources and methods can help approach new questions in both infectious and chronic disease.
Neil Rabinowitz, Postdoctoral Fellow, Laboratory for Computational Vision
Talk Title: The statistical structure of noise in the brain
Abstract: While those in machine learning have long drawn inspiration from brains for smart solutions to real-world problems, those of us who have tested out these analogue devices (either by owning one, or by interacting with others who do) are well aware that brains have some severe limitations. At a low level, they have to compute with noisy, slow, squidgy elements. At a high level, they’re prone to some serious mistakes. In this talk, I’ll argue that the noise in the brain is structured, and that by characterizing it, we can learn about the brain’s computational challenges, successes, and failures. In particular, I will focus on data from large populations of sensory neurons during a perceptual task, whose joint activity reveals the action of latent modulatory sources. Such data provide a rich testing ground for models that are both statistically principled and scientifically interpretable.
4th Data Science Showcase
Wednesday, October 22nd
Brian McFee, NYU Data Science Fellow
Talk title: Analyzing and Visualizing Musical Structure
Musical structure analysis seeks to produce a high-level description of the structural components of an audio recording, such as the boundaries marking transitions between sections (e.g., verse to chorus) or labeling repeated sections. The results of structure analysis can be used to generate visualizations and aid in discovery and understanding of musical content. In this talk, I’ll give a brief overview of the structure analysis problem and existing solutions, and then demonstrate a new technique based on spectral clustering. The proposed method simultaneously exploits local consistency and global repetition of acoustic features, and provides a natural encoding of structure at multiple levels of granularity.
Brenden Lake, NYU Data Science Fellow
Talk title: Towards Richer Models of Concept Learning in Machines
People can learn a new concept almost perfectly from just a single example, yet machine learning algorithms typically require tens, hundreds, or thousands of examples to perform similarly. People can also use their learned concepts in richer ways than conventional machine learning systems — for action, imagination, and explanation. I will describe a model that captures some of these human learning abilities by representing concepts as simple programs, or structured procedures that generate the observed data. The model achieves human-level performance on a one-shot classification task, and “visual Turing tests” show the model’s more creative generalizations can mimic the behavior of people.

1st Data Science Showcase
Monday, March 10th
Professor Jennifer Hill, Associate Professor of Applied Statistics, Steinhardt, gave a talk on “Causal Inference and Data Science — Why they need each other”
Jennifer Hill works on development of methods that help us to answer the causal question that are so vital to policy research and scientific development. In particular she focuses on situations in which it is difficult or impossible to perform traditional randomized experiments, or when even seemingly pristine study designs are complicated by missing data or hierarchically structured data. Most recently Hill has been pursuing two major strands of research. The first focuses on Bayesian nonparametric methods that allow for flexible estimation of causal models without the need for methods such as propensity score matching. The second line of work pursues strategies for exploring the impact of violations of typical assumptions in this work that require that all confounders have been measured. Hill is also the Co-Director of the Center for Research Involving Innovative Statistical Methodology (PRIISM) and the new Master’s Program in Applied Statistics for Social Science Research (A3SR)
