Abstract: Modern decision-making increasingly relies on complex data, imperfect models, and limited domain expertise--yet decisions must still be made with confidence and accountability. This talk presents a research perspective on visual analytics as a bridge between data, models, and human judgment. Through three case studies spanning public-health risk analysis, multivariate scientific visualization, and causal model auditing with large language models, I will show how interactive visualization can reveal structure in high-dimensional data, support reasoning under uncertainty, and help humans critically assess both statistical and AI-generated explanations. Together, these examples illustrate how visual analytics enables users not only to explore data, but to form, challenge, and refine beliefs that underpin scientific and societal decisions.

Scaling the NY AI Innovation Ecosystem

The State University of New York at Stony Brook will bring together leading AI experts to promote a future where AI drives responsible progress. This two-day event will provide a significant opportunity to explore the future of AI, exchange ideas, and connect with those at the forefront of research and deployment. We invite faculty, staff, and students from all SUNY institutions and beyond, as well as industry AI practitioners and policymakers to attend.

Recognized AI experts from academia, industry, and government will present on topics such as AI applications, innovative developments in research and technology, workforce development, as well as ethical and societal impacts.

A 90-minute poster session is included in the schedule. If you would like to submit an abstract for consideration, please see the Call for Abstracts. The poster session segment of the symposium will be held in honor of the Inauguration of Dr. Andrea Goldsmith, the State University of New York at Stony Brook's seventh President. Poster printing for all participants will be covered by the Inauguration Planning Committee. SUNY students presenting posters are also eligible for travel reimbursement.

We kindly ask faculty to encourage their students to attend and to submit their work for presentation.

For additional information and to register, visit the symposium website. Please direct any questions to suny-ai-symposium-sbu@stonybrook.edu.

Hidden Biases. Ethical Issues in NLP, and What to Do about Them presented by Dirk Hovy of Bocconi University

ABSTRACT: Through language, we fundamentally express who we are as humans. This property makes text a fantastic resource for research into the complexity of the human mind, from social sciences to humanities. However, it is exactly that property that also creates some ethical problems. Texts reflect the authors' biases, which get magnified by statistical models. This has unintended consequences for our analysis: If our data is not reflective of the population as a whole, if we do not pay attention to the biases contained, we can easily draw the wrong conclusions, and create disadvantages for our users.

In this talk, I will discuss several types of biases that affect NLP models, their sources, and potential counter measures: (1) Bias stemming from data, i.e., selection bias (if our texts do not adequately reflect the population we want to study), label bias (if the labels we use are skewed) and semantic bias (the latent stereotypes encoded in embeddings); (2) Biases deriving from the models themselves, i.e., their tendency to amplify any imbalances that are present in the data; (3) Design bias, i.e., the biases arising from our (the researchers) decisions which topics to analyze, which data sets to use, and what to do with them. For each bias, I will provide examples and discuss the possible ramifications for a wide range of applications, and various ways to address and counteract these biases, ranging from simple labeling considerations to new types of models.

He works in Natural Language Processing (NLP), a subfield of artificial intelligence. His research focuses on computational social science. His interests include integrating sociolinguistic knowledge into NLP models, using large-scale statistics to model the interaction between people's socio-demographic profile and their language use, and ethics for data science and algorithmic fairness.










Abstract:
Quantifying similarity is a central notion in science and data analysis, pervading everything from phylogenetic trees to the foundation of clustering. Unfortunately, despite being examined and applied for decades, traditional similarity and distance metrics have fundamental drawbacks. The key problem is that all of them are only defined over pairs of objects, so they scale quadratically when one tries to compare N objects. The present explosion in the amount of data available to us requires new ways to process information, and while some current algorithms can handle millions of points, we need alternatives applicable to billions. This is what motivated us to develop a new framework that can compare any number of objects at the same time. With this, we achieve an unprecedented linear scaling when comparing multiple objects. Here we will discuss the main properties of this formalism, along with its applications in drug design and to the analysis of Molecular Dynamics (MD) simulations. Our indices have proven to be incredibly versatile when applied to chemical space exploration and visualization, allowing us to rigorously quantify the chemical diversity of very large molecular libraries. This has led to the creation of several algorithms to sample important regions in chemical space, including a more efficient way of identifying the prevalence of activity cliffs. Additionally, our indices provide a convenient route to sample complex MD trajectories, allowing to identify representative structures very efficiently. Moreover, we can also cluster biological ensembles in a more robust way than with standard algorithms, which has led to our group's work on MDANCE, a very flexible and efficient open-source clustering module.

Abstract:
In this talk, I will present our journey of developing diverse, adaptive, uncertainty-calibrated AI planning agents that can robustly communicate and collaborate for multi-agent reasoning (on math, commonsense, coding, etc.) as well as for interpretable, controllable multimodal generation (across text, images, videos, audio, layouts, etc.). In the first part, we will discuss improving reasoning via multi-agent discussion among diverse LLMs and structured distillation of these discussion graphs (ReConcile, MAGDi), adaptively learning to balance abstraction, decomposition, refinement, and fast+slow thinking in LLM-agent reasoning (ReGAL, ADaPT, MAgICoRe, System-1.x), as well as confidence calibration in LLMs via speaker-listener pragmatic reasoning and making LLMs better teammates via multi-agent positive-negative persuasion balancing (LACIE, PBT). In the second part, we will discuss interpretable and control-lable multimodal generation via LLM-agents based planning and programming, such as layout-controllable image generation (and evaluation) via visual programming (VPGen+VPEval), consistent multi-scene video generation via LLM-guided planning (VideoDirectorGPT), interactive and composable any-to-any multimodal generation (CoDi, CoDi-2), as well as feedback-driven multi-agent interaction for adaptive environment/data generation via weakness discovery (EnvGen, DataEnvGym).
