Multilayer machine-learning framework for screening catalytic activity and selectivity

Abstract: Machine learning (ML) studies based on quantum chemical datasets have emerged as a powerful tool for accelerating catalyst discovery. However, their potential applications remain limited by high costs, low data quality, and restricted reliability. Here, we report a multilayer binary classification framework (MLBC) for screening catalytic performance in multistep processes with ML models. Key features include low-cost synthetic data generation via kinetic Monte Carlo simulations, high-quality data that capture catalytic behavior under reaction conditions, robust treatment of imbalanced data distributions, and descriptor selection that enhances reliability and interpretability. Using carbon dioxide (CO 2 ) hydrogenation to methanol (CH 3 OH) on copper (Cu)-based catalysts as a case study, the MLBC framework outperforms conventional ML models by demonstrating high reliability and strong generalization in classifying systems with activity and methanol selectivity exceeding those of Cu. In addition, feature analysis reveals that control over the critical transition steps between competing pathways governs activity and selectivity in CO 2 hydrogenation.

In addition to our speaker, we will have a number of CDS staff in attendance with expertise in AI methods and applications including image analysis, foundation models development, and inverse problem solving.

Abstract: The faster AI automation spreads through the economy, the more profound its potential impacts, both positive (improved productivity) and negative (worker displacement). The previous literature on AI Exposure cannot predict this pace of automation since it attempts to measure an overall potential for AI to affect an area, not the technical feasibility and economic attractiveness of building such systems. In this work, we present a new type of AI task automation model that is end-to-end, estimating: the level of technical performance needed to do a task, the characteristics of an AI system capable of that performance, and the economic choice of whether to build and deploy such a system. The result is a first estimate of which tasks are technically feasible and economically attractive to automate - and which are not. We focus on computer vision, where cost modeling is more developed. We find that at today's costs U.S. businesses would choose not to automate most vision tasks that have AI Exposure, and that only 23% of worker wages being paid for vision tasks would be attractive to automate. This slower roll-out of AI can be accelerated if costs fall rapidly or if it is deployed via AI-as-a-service platforms that have greater scale than individual firms, both of which we quantify. Overall, our findings suggest that AI job displacement will be substantial, but also gradual - and therefore there is room for policy and retraining to mitigate unemployment impacts.

Abstract:

Photorealistic editing of human facial expressions and head articulations remains a long-standing topic in the computer graphics and computer vision community. Methods enabling such control have great potential in AR/VR applications where a 3D immersive experience is valuable, especially when this control extends to novel views of the scene in which the human subject appears. Traditionally, 3D Morphable Face Models (3DMMs) have been used to control the facial expressions and head pose of a human head. However, the PCA-based shape and expression spaces of 3DMMs lack the expressivity. They cannot model essential elements of the human head such as hair, skin details, and accessories such as glasses that are paramount for realistic reanimation. In this thesis, we present a set of methods that enables facial reanimation, starting from editing expressions in still face images to creating fully controllable neural 3D portraits with control over facial expressions, head pose, and viewing direction of the scene using only casually captured monocular videos from a smartphone to finally achieving studio-like quality from the said monocular captures.
First, we propose a method for editing facial expressions in near-frontal facial images through the unsupervised disentangling of expression-induced deformations and texture changes. Next, we extend facial expression editing to human subjects in 3D scenes. We represent the scene and the subject in it using a semantically guided neural field. This enables control over the subject's facial expressions and the viewing direction of the scene they're in. We then present a method that learns, in an unsupervised manner, to deform static 3D neural fields using facial expression and head-pose dependent deformations, enabling control over facial expressions and head pose of the subject along with the viewing direction of the 3D scene they're in. Next, we propose a method that makes the learning of the aforementioned deformation field robust to strong illumination effects, which adversely impact the registration of the deformation. We then propose an extension of this unsupervised deformation model to 3D Gaussian splatting by constraining it using a 3D morphable model, resulting in a rendering speed of 18 FPS--a 100x speed improvement over prior work. Finally, we propose a method that bridges the quality gap between 3D portraits created using in-the-wild monocular data and multi-view studio capture data. We accomplish this using a two-stage method. First, we train a StyleGAN to relight and inpaint in-the-wild face texture maps (with strong illumination effects and incompletely captured regions). Next, we both reconstruct and generate identity-specific facial details that may be poorly captured in the in-the-wild captures. Once trained, we can generate studio-like complete avatars from monocular phone captures.

CSE 600 Talk: Squeezing Software Performance via Eliminating Wasteful Operations presented by Xu Liu

ABSTRACT: Inefficiencies abound in complex, layered software. A variety of inefficiencies show up as wasteful memory operations, such as redundant or useless memory loads and stores. Aliasing, limited optimization scopes, and insensitivity to input and execution contexts act as severe deterrents to static program analysis. Microscopic observation of whole executions at instruction- and operand-level granularity breaks down abstractions and helps recognize redundancies that masquerade in complex programs. In this talk, I will describe various wasteful memory operations, which pervasively exist in modern
software packages and expose great potential for optimization. I will discuss the design of a fine-grained instrumentation-based profiling framework that identifies wasteful operations in their contexts, which guides nontrivial performance improvement. Furthermore, I will show our recent improvement to the profiling framework by abandoning
instrumentation, which reduces the runtime overhead from 10x to 3% on average. I will show how our approach works for native binaries and various managed languages such as Java, yielding new performance insights for optimization.

The Future Histories Studio at Stony Brook University and Guggenheim New York are collaborating to present a day-long symposium on October 24 at the Simons Center for Geometry and Physics. This conference will explore urgent questions at the intersection of artificial intelligence, machine learning, and the human, and is co-organized by Noam Segal, LG Electronics Associate Curator at Guggenheim New York. In this role, Noam plays an important part in researching these topics, promoting a deeper understanding of the ways in which contemporary artists use new technologies, and developing and supporting the Guggenheim's engagement with technology-based art under the LG Guggenheim Art and Technology Initiative.

The event examines the profound transformations brought by automation--how AI compels us to rethink cognition, agency, and the conditions of reason itself. As these systems become ever more embedded in daily life--largely invisible yet deeply consequential--they challenge the very foundations of subjectivity and governance. We are surrounded by logics we cannot fully access, yet which shape our realities, while new forms of alterity arise--distinct modes of reasoning that propose collective unknowns beyond established frameworks of knowledge.

This emerging terrain invites us to consider cognitive plurality, where biological and technological intelligences generate new categories, concepts, and understandings. Once unique to humans--art, authorship, judgment, invention--are now co-articulated with systems of computation and planetary-scale infrastructure. The symposium brings together artists, scholars, and technologists to probe the cultural, philosophical, and ecological implications of this entanglement.

The concept of neurodiversity has shown that neurological differences such as autism, ADHD, and dyslexia are not deficits but variations that enrich collective life. Extending this to machines can be provocative: just as neurodivergence unsettles fixed definitions of intelligence, so too AI challenges anthropocentric assumptions about cognition. Yet the analogy is limited. Neurodiversity is rooted in the lived struggles of human communities, while machines neither think nor struggle. Human cognition involves perception, learning, memory, and reasoning through embodied experience. Machine cognition, by contrast, is computational pattern recognition and statistical modeling, without consciousness or lived context, and with only narrow forms of sensing.

For this reason, the symposium advances a broader framework of cognitive diversity or technodiversity--a recognition of proliferating intelligences, human, machinic, and hybrid, as part of a shared ecology. This shift calls for new models of creativity, responsibility, and collaboration that honor the irreducibility of human thought while engaging the radical alterity of machine logics.

Uncertainty-Aware Adaptation of LLMs for Protein-Protein Interaction Analysis

Abstract: Identification of protein-protein interactions (PPIs) helps derive cellular mechanistic understanding, particularly in the context of complex conditions such as neurodegenerative disorders, metabolic syndromes, and cancer. Large Language Models (LLMs) have demonstrated remarkable potential in predicting protein structures and interactions via automated mining of vast biomedical literature; yet their inherent uncertainty remains a key challenge for deriving reproducible findings, critical for biomedical applications. In this study, we present an uncertainty-aware adaptation of LLMs for PPI analysis, leveraging fine-tuned LLaMA-3 and BioMedGPT models. To enhance prediction reliability, we integrate LoRA ensembles and Bayesian LoRA models for uncertainty quantification (UQ), ensuring confidence- calibrated insights into protein behavior. Our approach achieves competitive performance in PPI identification across diverse disease contexts while addressing model uncertainty, thereby enhancing trustworthiness and reproducibility in computational biology. These findings underscore the potential of uncertainty-aware LLM adaptation for advancing precision medicine and biomedical research.

Please join us for the next CSE 600 Seminar this Friday, October 11th, at 2:30pm in New Computer Science 120 given by Assistant Professor Mohammad Javad Amiri. Abstract: Today's distributed transaction processing systems must deal with untrustworthy environments where multiple mutually distrustful entities communicate with each other, and maintain data on untrusted infrastructure. Byzantine Fault-Tolerant (BFT) protocols have recently been extensively used by distributed transaction processing systems to establish consensus on the order of transactions. However, the proliferation of different BFT protocols has made it difficult to navigate the BFT landscape, let alone determine the protocol that best meets application needs. Moreover, as novel smart contracts, modern hardware, and new cloud platforms arise, future-proof distributed transaction processing systems need to be designed with full-stack adaptivity in mind. This talk presents our vision for a reinforcement learning (RL)-based distributed transaction processing system that adjusts effectively in real-time to changing fault scenarios and workloads.
