Seed Time: SILENT RUNNING (1972) on 35mm
SILENT RUNNING (DOUGLAS TRUMBULL, 1972, 89 MINS, 35MM)
RSVP
Directed by visual effects master Douglas Trumbull (2001: A SPACE ODYSSEY, CLOSE ENCOUNTERS OF THE THIRD KIND, BLADE RUNNER), SILENT RUNNING was a prescient and unique entry in the run of cautionary ecological-themed science fiction films of the 1970s. Here, instead of mutated or rampaging members of the animal kingdom, the focus is on fauna and one man’s desperate attempt to save the surviving species that had once flourished on a now-plant barren Earth. Bruce Dern plays Freeman Lowell, a botanist on one of several cargo spaceships stationed near Saturn that house giant greenhouses for a freighter megacorporation. When he and his fellow crew members are ordered to destroy their cargo, Lowell takes radical steps to ensure the survival of his precious specimens. The film has become a cult favorite over the years, buoyed by a strong performance by Dern, a thoughtful and quirky screenplay (by DEER HUNTER director Michael Cimino and television producer Steven Bochco), three engaging droids (Huey, Dewey, and Louie), and a soundtrack by musician and composer Peter Schickele ( P. D. Q. Bach), with songs sung by Joan Baez. Made during the height of American concerns around environmental degradation in the 1970s, SILENT RUNNING is both a time capsule and a prescient meditation on the relationship between human, plant, and artificial intelligence.

Talk Title
Data-Efficient Graph Learning
Abstract
The world around us -- and our understanding of it -- is rich in relational structure: from atoms and their interactions to objects and entities in our environments. Graphs, with nodes representing entities and edges representing relationships between entities, serve as a common language to model complex, relational, and heterogeneous systems. Despite the success of recent deep graph learning, the efficacy of existing efforts heavily depends on the ideal data quality of the observed graphs and the sufficiency of the supervision signals provided by the human-annotated labels, leading to the fact that those carefully designed models easily fail in resource-constrained scenarios.
In this talk, I will present my recent research contributions centered around data-efficient learning for relational and heterogeneous graph-structured data. First, I will introduce what data-efficient graph learning is and my contributions to different research problems under its umbrella, including graph few-shot learning, graph weakly-supervised learning, and graph self-supervised learning. Based on my work, I will elucidate how to push forward the performance boundary of graph learning models especially graph neural networks with low-cost human supervision signals. I will also touch upon the real-world applications of data-efficient graph learning to different domains and finally conclude my talk with a brief overview of my future research agenda.

WED@NICO SEMINAR: Chris Bail, Duke University "Bridging Divides with Generative AI"

12:00 PM
//
Lower Level, Chambers Hall
Details
Speaker:
Chris Bail, Professor of Sociology, Political Science, and Public Policy, Duke University
Title:
Bridging Divides with Generative AI
Abstract:
Political discourse is the soul of democracy, but misunderstanding and conflict can fester in divisive conversations. The widespread shift to online discourse exacerbates many of these problems and corrodes the capacity of diverse societies to cooperate in solving social problems. Scholars and civil society groups promote interventions that make conversations less divisive or more productive, but scaling these efforts to online discourse is challenging. This talk will describe a large-scale experiment that demonstrates how online conversations about divisive topics can be improved with AI tools. Specifically, my colleagues and employ a large language model to make real-time, evidence-based recommendations intended to improve participants’ perception of feeling understood. These interventions improve reported conversation quality, promote democratic reciprocity, and improve the tone, without systematically changing the content of the conversation or moving people’s policy attitudes. These findings replicate during a half year experiment on a large social media platform.
Speaker Bio:
Chris Bail is Professor of Sociology, Political Science, and Public Policy at Duke University, where he founded the Polarization Lab. He studies how artificial intelligence shapes human behavior in a range of different settings—and social media platforms in particular. Chris is passionate about building the field of computational social science. He is the Editor of the Oxford University Press Series in Computational Social Science and the Co-Founder of the Summer Institutes in Computational Social Science. Chris received his PhD from Harvard University in 2011.

• NU-authenticated attendees will be automatically admitted. Others, please email amy.nedoss@northwestern.edu to be admitted from the waiting room.
Abstract:
At the Toyota Research Institute (TRI), we've been working on behavior cloning for dexterous manipulation. Building on the Diffusion Policy framework that we've recently developed in collaboration with Shuran Song, we now have a very solid pipeline for taking ~50-100 bimanual haptic teleop demonstrations and turning that into a surprisingly effective visuomotor (+tactile) policy. Because there is no explicit state representation required, these skills work equally well manipulating deformable, liquid, or other difficult to model tasks as they do for more traditional rigid-object manipulation. We're actively scaling this up into the multi-task setting and now see a plausible path towards "Large Behavior Models". This behavior cloning pipeline is working incredibly well, and must be understood deeply in the broader context of output-feedback control. Time permitting, I'll also tell you a bit about some new results in optimization-based planning and control, and where they might fit in the age of foundation models.

WED@NICO SEMINAR: Daniel Harris, Brown University "At the interface: physical analogy with interfacial fluid mechanics"
Northwestern Institute on Complex Systems (NICO)
12:00 PM
//
Lower Level, Chambers Hall
Details
Speaker:
Daniel Harris, Assistant Professor of Engineering, Brown University
Title:
At the Interface: Physical Analogy with Interfacial Fluid Mechanics
Abstract:
Maxwell describes physical analogy as a "partial similarity between the laws of one science and those of another which makes each of them illustrate the other." Hydrodynamics has long since been a source of physical analogy, sharing similar equations with other seemingly disparate fields of physics. The focus of this talk will be on physical analogies with interfacial fluid systems, where accessible tabletop experiments can be used to investigate and communicate physical phenomena at vastly different scales. Following a brief review of some historical examples of analogy in interfacial fluid mechanics, I will describe two recent tabletop experiments developed in our lab that share similarities with certain microscopic colloidal systems. While physical analogy can be fruitfully used to advance science across disciplines, it can also be leveraged to enhance scientific communication and pedagogy.
Speaker Bio:
Daniel M. Harris is an Assistant Professor of Engineering at Brown University in the Fluids and Thermal Sciences group. Before joining Brown, Dan was a Postdoctoral Research Associate and Lecturer at the University of North Carolina at Chapel Hill in the Department of Mathematics.

Statistics and Data Science Seminar: "T-Stochastic Graphs"
Department of Statistics and Data Science
11:00 AM
//
Ruan Conference Room – lower level, Chambers Hall
Details
T-Stochastic Graphs
Karl Rohe, Professor of Statistics, University of Wisconsin-Madison
Abstract: Previous statistical approaches to hierarchical clustering for social network analysis all construct an "ultrametric" hierarchy. While the assumption of ultrametricity has been discussed and studied in the phylogenetics literature, it has not yet been acknowledged in the social network literature. We show that "non-ultrametric structure" in the network introduces significant instabilities in the existing top-down recovery algorithms. To address this issue, we introduce an instability diagnostic plot and use it to examine a collection of empirical networks. These networks appear to violate the "ultrametric" assumption. We propose a deceptively simple class of probabilistic models called T-Stochastic Graphs which impose no topological restrictions on the latent hierarchy. Perhaps surprisingly, this model generalizes the previous models. To illustrate this model, we propose six alternative forms of hierarchical network models and then show that all six are equivalent to the T-Stochastic Graph model. These alternative models motivate a novel approach to hierarchical clustering that combines spectral techniques with the well-known Neighbor-Joining algorithm from phylogenetic reconstruction. We prove this spectral approach is statistically consistent.

An Automatic Finite-Sample Robustness Check: Can Dropping a Little Data Change Conclusions?
Tamara Broderick, Associate Professor, Department of Electrical Engineering and Computer Science at MIT
Abstract: Practitioners will often analyze a data sample with the goal of applying any conclusions to a new population. For instance, if economists conclude microcredit is effective at alleviating poverty based on observed data, policymakers might decide to distribute microcredit in other locations or future years. Typically, the original data is not a perfect random sample from the population where policy is applied -- but researchers might feel comfortable generalizing anyway so long as deviations from random sampling are small, and the corresponding impact on conclusions is small as well. Conversely, researchers might worry if a very small proportion of the data sample was instrumental to the original conclusion. So we propose a method to assess the sensitivity of statistical conclusions to the removal of a very small fraction of the data set. Manually checking all small data subsets is computationally infeasible, so we propose an approximation based on the classical influence function. Our method is automatically computable for common estimators. We provide finite-sample error bounds on approximation performance and a low-cost exact lower bound on sensitivity. We find that sensitivity is driven by a signal-to-noise ratio in the inference problem, does not disappear asymptotically, and is not decided by misspecification. Empirically we find that many data analyses are robust, but the conclusions of several influential economics papers can be changed by removing (much) less than 1% of the data.

Talk Title:
Tuning into the Cosmic Symphony: Pulsar Timing, the Gravitational Wave Background, and Beyond
About this Talk: In the cosmic symphony of gravitational waves, supermassive black hole binaries provide the bass notes. However, when these colossal duos play all at once, their individual melodies overlap into an indistinct rumble. After 15 years of effort, astronomers announced last summer that they have at last found evidence for this background hum of gravitational waves using an observatory that spans our entire Milky Way galaxy. Tune in with us to hear more about gravitational wave symphonies, monstrous black holes, colliding galaxies, dead stars, and more!
About the Presenter:
Dr. Caitlin A. Witt is the CIERA-Adler Postdoctoral Fellow at CIERA and the Adler Planetarium. Her main research interests are supermassive black hole binaries (SMBHBs), the low frequency gravitational waves they emit, and their effects on their host galaxies. As a member of the North American Nanohertz Observatory for Gravitational Waves (NANOGrav), Caitlin leads efforts to detect continuous gravitational waves from individual SMBHBs with pulsar timing arrays and develop methods to use information learned in electromagnetic searches for SMBHBs in multi-messenger searches for these elusive pairs. She is also interested in searches for periodicity in AGN light curves, efficient computational analysis of large data sets, and data visualization. At Adler, Caitlin is working with the Public Observing team to develop a research program for Chicago students using Adler’s Doane Observatory.

CIERA - Annual Public Lecture Series
Next Steps in Python: Parsing text with NLTK
Northwestern IT Research Computing and Data Services
12:00 PM
Details
Next Steps in Python Workshop Series is a seven-part series covering intermediate Python skills, tips, and tricks guaranteed to make your coding life easier. You do not need to attend each session to participate - there is a new lesson each week.
Each one-hour session meets via Zoom on Wednesdays at noon, CDT.
Parsing text with NLTK
NLTK is one of Python's main libraries for natural language processing (NLP). This workshop introduces the library by focusing on how to parse text to create bags of words. In other words, this workshop teaches how to go from raw text (a string) to a list of words that can be used for different NLP methods.
Prerequisites: Participants should be familiar with Python at an introductory level.

WED@NICO SEMINAR: Serguei Saavedra, MIT "How Do Ecological Systems Become (re)Assembled?"
Northwestern Institute on Complex Systems (NICO)
12:00 PM
//
Lower Level, Chambers Hall
Details
Speaker:
Serguei Saavedra, Associate Professor, Department of Civil and Environmental Engineering, MIT
Title:
How Do Ecological Systems Become (re)Assembled?
Abstract:
One of the most iconic thought experiments in biology is what would happen if we could rewind the tape of life on Earth and play it again. Would the tape have a different story in every replay? Or is there a general order of events? The relevance of this thought experiment is not just philosophical or counterfactual, because (re)assembly processes undergone by ecological systems, from microbes to mega-fauna, are continuously replicating the experiment. By integrating theoretical and empirical work, in this talk I will provide a guideline to increase our understanding about the (re)assembly possibilities of ecological systems. Explaining and predicting the (re)assembly of ecological systems underpins our ability to develop successful interventions in bio-restoration, bio-technologies, and bio-medicine.
Speaker Bio:
Serguei Saavedra is an Associate Professor at MIT in the Department of Civil and Environmental Engineering. He is also an external faculty at Santa Fe Institute.
