Talk Title
The Rational Programmer, A Method for Investigating Programming Language Pragmatics
Abstract
"The work of software developers directly depends on decisions that
language creators make for them. Therefore, when language creators choose
from a number of design alternatives, they should consider how their
choices affect the developers. Specifically, language creators should
consider the use of a language feature in particular work contexts, an
idea analogous to what linguists call ``pragmatics.'' However, so far,
there are only a few instruments for investigating Programming Language
(PL) pragmatics.
To address this gap, I have developed a new scientific instrument called
the Rational Programmer. At the technical level, the Rational Programmer
method puts the idea of simulation, a technique with a long history in
Computer Science, to new use in PL research. The heart of a
rational-programmer simulation is an algorithmic abstraction of using a
language feature for information gathering, interpretation and action in a
work context. Typically, a rational-programmer simulation produces a
recommendation for a use strategy that a developer can employ while
working in the given context. It may also identify a problematic aspect of
a feature's design with concrete evidence, which then the creators and
developers can leverage to address the problem. Finally, a
rational-programmer simulation can inform instructors how to teach
students the effective use of a feature. In this talk, I will demonstrate
the workings of the Rational Programmer method with examples."

WED@NICO SEMINAR: Oscar Stuhler, Northwestern University "Studying Textual Representations of Social Structures"
Northwestern Institute on Complex Systems (NICO)
12:00 PM
//
Lower Level, Chambers Hall
Details
Speaker:
Oscar Stuhler, Assistant Professor, Department of Sociology, Northwestern University
Title:
Studying Textual Representations of Social Structures
Abstract:
Textual data contain rich accounts of actions taken by different actors, of relationships, and of particular identities’ attributes. In other words, texts contain representations of social structures. Sociology has a long tradition of formally studying such structures. However, with the embrace of computational text analysis, sociologists' focus has shifted from grammar-based approaches to ones based on co-occurrence, such as word embeddings. Time to bring grammar back in! In this talk, I will first present a framework for extracting grammatically structured information like the above from text. I then show how this allows us to study larger discursive patterns by presenting both past and ongoing research. In particular, I will be talking about gender and agency in fiction writing (1850-2010) and contending conceptions of refugees in German news. I will close with some work in progress that leverages generative large language models to extend this ongoing research program.
Speaker Bio:
Oscar Stuhler is a sociologist studying discourse with formal, quantitative methods. Much of his work focuses on how to measure, analyze, and theorize textual representations of social structures. Oscar is an Assistant Professor at Northwestern University’s Department of Sociology. He completed his PhD in sociology at New York University.

Complex Systems Seminar: Jennifer Schwarz: "Physical Processes that Function as Learning Mechanisms"
Physics and Astronomy Complex Systems Seminars
2:00 PM
//
F160, Technological Institute
Details
All biological systems are learning systems. Moreover, all biological systems are physical systems. Therefore, there exists a direct connection between physics and learning. To tease out these statements, we will discuss efforts to uncover new learning mechanisms, or algorithms, from a physics perspective, aka physical learning, such as multi-mechanism learning (MML) and frequency propagation (FP). MML can be implemented to recognize static patterns as well as dynamic ones and provides a simple physical explanation for the underlying basis of bidirectionality observed in neuronal circuits, for example. While MML and FP are supervised physical learning algorithms, efforts are also underway to develop unsupervised physical learning algorithms given the recent observation that physical learning can be viewed as feedback-based aging in a glassy landscape. All in all, these combined efforts point towards a unified framework of learning with and without brains that may help us build both better artificial intelligence systems and biological intelligence systems, including a network of brain organoids.

Advancing arrhythmia patient care with digital twins and AI
ABSTRACT:
Precision medicine is envisioned to provide therapy tailored to each patient. The rapidly increasing ability to capture extensive patient data, coupled with machine learning, is a pathway to achieving this vision. A different pathway towards precision medicine is the increasing ability to encode known physics laws and physiology knowledge within mathematical equations and to adapt such models to represent the behavior of a specific patient.
Wouldn’t it be great to have a digital representation of ourselves that allows doctors to simulate our personal medical history and health conditions using relationships learned both from data and from biophysics knowledge? That virtual replica of ourselves would integrate data-driven machine learning and multiscale physics-based modeling to continuously update itself as our health condition changes and more information about our interaction with the environment is acquired. These digital twins would forecast the trajectory of the patient’s disease, estimate risk of adverse events, and predict treatment response so that the potential outcome would inform treatment decision.
This presentation explores the synergies that have been achieved between machine learning and mechanistic physics-based heart models towards enabling precision medicine in cardiology. It showcases how machine learning and multiscale cardiac modeling complement each other in engineering your heart’s health. A highlight is the robust prediction of sudden cardiac death risk in different heart diseases. Another application of the heart digital twin technology is illustrated by the development of a precise treatment for patients suffering from arrhythmias. This application prevents future re-hospitalizations and repeat procedures, shifting the treatment selection from being based on the state of the patient today to optimizing the state of the patient tomorrow.

A holistic and critical look at language agents
Yu Su, Assistant Professor, Department of Computer Science and Engineering, The Ohio State University
Abstract: How are the contemporary AI agents powered by LLMs different from those of the earlier generations? I argue that their most distinct trait is a new capability of using language as a vehicle of both 'thought' and communication, and therefore they are best called "language agents." I will describe a conceptual framework for these language agents, followed by a more in-depth discussion on several core competencies, including memory, planning, and tool use. I will conclude the talk with interesting future directions.

"Harnessing big data for precision medicine”
Abstract:
Despite advancements in treatment options for cancer, a majority of cancer types continue to lack fully characterized and effective targeted therapies to improve disease diagnostics, prognoses, and patient survival outcomes. Therefore, there is an urgent need to gain a more comprehensive understanding of the molecular basis of diseases and develop novel prognostic and therapeutic strategies. Our lab utilizes cutting-edge techniques in systems biology to understand the molecular mechanisms of complex diseases. We conducted a series of pan-cancer analyses to provide clinical insights into cancer therapy, including RNA targeted therapy (Journal of the National Cancer Institute, 2018; Genome Medicine, 2019a; Genome Medicine, 2019b; Nature Communications, 2019; Cancer Research, 2022), chronotherapy (Cell Systems, 2018), hypoxia-targeted therapy (Nature Metabolism, 2019), target therapy (Genome Medicine, 2020a), autophagy-targeted therapy (Nature Communications, 2022), and immunotherapy (Nature Immunology, 2019; Nature Communications, 2020a; Nature Communications, 2020b; Genome Medicine, 2020b; Advanced Science, 2020; Journal of the National Cancer Institute, 2021; Cancer Cell, 2021; The Innovation, 2021; Journal for Immunotherapy of Cancer, 2022; Nature Reviews Clinical Oncology, 2022; Cell Metabolism, 2023; The Innovation, 2023; Nature Reviews Clinical Oncology, 2023). These studies shed light on future clinical considerations for the development of innovative therapies for cancer types currently lacking effective treatment options. We will further develop highly innovative prognostic and therapeutic strategies with the potential to produce a major impact on biomedical research.

Subsampling for Big Data Regression with Measurement Constraints
Lin Wang, Assistant Professor of Statistics, Purdue University
Abstract: Despite the availability of extensive data sets, it is often impractical to observe the labels for all data points due to various measurement constraints in many applications. To address this challenge, subsampling approaches can be employed to select a subset of design points from a large pool for observation, resulting in substantial savings in labeling costs. In this presentation, I will introduce our recent research on computationally feasible subsampling techniques. Our primary focus is on regression with labeled data, which includes linear regression, ridge regression, and nonparametric additive regression. For these regression tasks, we have developed sampling approaches that aim to minimize the mean squared error in estimations and predictions. We will demonstrate the effectiveness of our proposed approaches through theoretical analysis and extensive numerical results.

Appl Math: Pedram Hassanzadeh on "Integrating the Spectral Analyses of Neural Networks and Nonlinear Physics for Explainability, Generalizability, and Stability"
McCormick-Engineering Sciences and Applied Mathematics (ESAM)
11:15 AM
//
M416, Technological Institute
Details
Title: Integrating the Spectral Analyses of Neural Networks and Nonlinear Physics for Explainability, Generalizability, and Stability
Speaker: Pedram Hassanzadeh, The University of Chicago
Abstract: In recent years, there has been substantial interest in using deep neural networks (NNs) to improve the modeling and prediction of complex, multiscale, nonlinear dynamical systems such as turbulent flows and Earth’s climate. In idealized settings, there has been some progress for a wide range of applications from data-driven spatio-temporal forecasting to long-term emulation to subgrid-scale modeling. However, to make these approaches practical and operational, i.e., scalable to real-world problems, a number of major questions and challenges need to be addressed. These include 1) instabilities and the emergence of unphysical behavior, e.g., due to how errors amplify through NNs, 2) learning in the small-data regime, 3) interpretability based on physics, and 4) out-of-distribution generalization (e.g., extrapolation to different parameters, forcings, and regimes) which is essential for applications to non-stationary systems such as a changing climate. While some progress has been made in addressing (1)-(4), e.g., doing transfer learning for generalization, these approaches have been often ad-hoc, as currently there is no rigorous framework to analyze deep NNs and develop systematic and general solutions to (1)-(4). In this talk, I will discuss some of the approaches to address (1)-(4), for example, once we identify spectral bias as the cause of instabilities in state-of-the-art weather models like Pangu-weather, GraphCast, and FourCastNet. Then I will introduce a new framework that combines the spectral (Fourier) analyses of NNs and nonlinear physics, and leverages recent advances in theory and applications of deep learning, to move toward rigorous analysis of deep NNs for applications involving dynamical systems. For example, this approach can guide and explain transfer learning and pruning in such applications. I will use examples from turbulence modeling and weather/climate prediction to discuss these methods and ideas.

EES Seminar- Environmental Engineers Are the Circular Carbon Engineers- Jason Ren
McCormick - Civil and Environmental Engineering (CEE)
2:00 PM
//
A230, Technological Institute
Details
Abstract: Achieving carbon circularity and net zero emissions requires a comprehensive understanding of emissions and re-valorization of waste carbon, while keeping fossil carbon underground. Environmental engineers are uniquely positioned to lead sustainable carbon management as the “circular carbon engineers”. For example, modern wastewater treatment is evolving from “removal-centered” to a “recovery-oriented” approach, and the increasing availability of low-cost renewable electricity presents new opportunities to convert "electrons to molecules". This presentation will highlight recent efforts to address knowledge gaps in the complex GHG emission profiles of the wastewater sector, utilizing both field studies and data science methods. It will also discuss technologies for electrifying treatment processes, co-valorizing wastewater and CO2, performing electrolysis of impaired water, and producing commodity chemicals using electroactive membranes.
Bio: Dr. Zhiyong Jason Ren (https://ren.princeton.edu) is a professor in the department of Civil and Environmental Engineering and the Andlinger Center for Energy and the Environment at Princeton University. He leads the Princeton Water & Energy Technologies (WET) Lab with research focusing on water sector decarbonization and digitalization. His group uses electrochemistry, microbiology, and data science tools to gain insights into the fundamental determining factors, and they develop models and technologies for resource recovery during environmental and chemical processes. Dr. Ren has received numerous recognitions including the Walter J. Weber, Jr. AEESP Frontier in Research Award (2024), the Paul L. Busch Award (2021), and Walter L. Huber Research Prize (2020). He is a Fellow of Royal Society of Chemistry and International Water Association. He is an Associate Editor for Environmental Science & Technology (ES&T) and ES&T Letters. Ren received his Ph.D. in environmental engineering from Penn State University.

WED@NICO SEMINAR: Guy Aridor, Kellogg School of Management "The Value of Belief Data in Online Recommendation Systems"
Northwestern Institute on Complex Systems (NICO)
12:00 PM
//
Lower Level, Chambers Hall
Details
Speaker:
Guy Aridor, Assistant Professor of Marketing, Kellogg School of Management, Northwestern University
Title:
The Value of Belief Data in Online Recommendation Systems
Abstract:
Designing algorithmic recommendation systems on online platforms is simultaneously a data collection and an algorithmic problem, though most work has focused on the algorithmic aspects. In this talk, I’ll describe several recent papers that show the value of collecting data not just on consumption behavior, but also on pre-consumption attitudes — what consumers think about items they have not consumed. I’ll discuss how an economic model of user consumption choices in environments that incorporates these attitudes can rationalize empirical consumption patterns on a movie recommendation platform, MovieLens. We then test the assumptions of and the hypotheses generated by this model in a field experiment on MovieLens that collects such belief data in order to decompose the mechanisms that drive the effectiveness of recommendations. Finally, I’ll discuss a practical procedure and a resulting open-source dataset collected via this procedure that we implement on the MovieLens platform that allows for the collection of such data at scale that can enable the incorporation of such data into the design of recommendation systems.
Speaker Bio:
Guy Aridor is an Assistant Professor of Marketing at Northwestern Kellogg School of Management and a research affiliate at CESifo. His research employs tools from economics and quantitative marketing to investigate policy and antitrust issues in the digital economy, as well as the effects of new technologies on consumer behavior. He has a particular interest in consumer privacy, recommendation systems, and social media platforms. He holds a PhD in economics from Columbia University and a BA in pure/applied mathematics, computer science, and economics from Boston University.
