Data Stacks is SBU Libraries' workshop series for building practical data skills, led by Ahmad Pratama, SBU Libraries Data Literacies Lead.
In this hands-on session, learn how to move beyond descriptive statistics to draw evidence-based conclusions using inferential techniques in Python and/or R. Explore how Generative AI can assist in writing statistical code & explaining outputs while identifying misleading, incomplete, or overly confident AI-generated interpretations.

BAM includes one short talk on AI research happening at BNL, followed by an open mixer over coffee and snacks for everyone to network and discuss all things AI. The first half hour will consist of presentations that will be available via ZOOM, and the second half hour will be for in person only networking.
Join us every other Tuesday at noon in CDSD's Training Room (building 725, 2nd floor) to learn about interesting AI methods and applications, engage with potential collaborators, prepare for pending FASST funding calls, and build a community of AI for Science at BNL.
HPCortex - a new, general-purpose machine learning library for HPC
Abstract: I will introduce HPCortex, a lightweight, C++, MPI-native machine-learning library for heterogeneous HPC systems. It implements many common architecture patterns including transformers, graph neural networks, and convolutional networks, and delivers performance portability across NVIDIA, AMD, and Intel GPUs while depending only on MPI and standard compiler/BLAS stacks. I will illustrate its capabilities via a surrogate model for the RHIC AGS Booster digital twin, a simple GNN for a coupled spring system, and a compact language model, then outline the roadmap.
Biography: Christopher is a research scientist and head of the Scientific Computing Applications Group in the Computational Science Department at Brookhaven National Laboratory. Previously he was an assistant staff scientist in the Physics Dept. at Columbia University, and held physics postdoctoral research positions at both Brookhaven and Columbia. He earned his Ph.D in Theoretical Physics from the University of Edinburgh, UK.
His scientific background is in lattice QCD and high performance computing, but since joining Brookhaven in 2020 his research interests have expanded to include machine learning, applied mathematics and performance analysis, with a particular emphasis on building tools to support scientific research on HPC systems.

What AI tools are available to help with the scholarly research process? Are they helpful? What do they do and is it worth the time and energy to try them out? Join librarian Christine Fena to explore and compare established and emerging AI research tools such as Elicit, Scite, Consensus, and Undermind. The workshop will not offer a lengthy tutorial on how to use any of these tools, but will provide a starting point to understanding what they are, what new ones are emerging, and how AI research assistants might bring changes to your search process. All are welcome!
Title: AI-Driven Target Selection Methods for Touch and Gaze Input
Abstract: Accurately selecting targets is an essential aspect of Human-Computer Interaction. Erroneous selections can cause tedious undo and redo actions. Additionally, some selection errors are non-reversible and can lead to undesirable consequences. However, high-accuracy target selection remains a challenge on touchscreen devices due to the small target size and imprecise touch inputs, and in gaze interaction because of the gaze tracking noise and no easy-to-use selection action. We first propose ReLM, a Reinforcement Learning-based Method for touchscreen target selection. ReLM can automatically show suggestions and require a second touch if the input is ambiguous, and can directly select a target candidate when the input is certain. Our empirical evaluation shows that ReLM reduces the error rate from 6.92% to 1.63%, and the selection time from 2.23s to 1.59s over Shift, an existing suggestion-based method. Compared to BayesianCommand, a direct selection-based method, our ReLM reduces the error rate from 3.64% to 0.89%, while increasing the selection time by only 200 ms. Secondly, we investigate how to improve target selection performance for gaze interaction. We propose BayesGaze, an eye-gaze based target selection method. It accumulates the signal of each gaze point for selecting a target calculated by Bayes Theorem, and uses a threshold mechanism to determine the target selection. Our investigation shows that BayesGaze improves target selection accuracy and speed over a dwell-based selection method, and the Center of Gravity Mapping method.

Developing research questions & effective search strategies can be challenging, and the growing use of generative AI adds a new layer of complexity to the research process. This workshop will explore how generative AI can complement traditional research methods while navigating important considerations around accuracy, transparency, privacy, and reliability. No prior AI experience is required.

Experiencing Machine Learning in Collider-Accelerator Control System
Abstract: The Relativistic Heavy Ion Collider (RHIC) at Collider-Accelerator Department (C-AD) of BNL provides the world's only high-energy polarized proton beam. It is in the unique position to study where nuclei obtain their spin. During 25 years of operation at RHIC, the C-AD controls group has developed its own control system to tune the accelerator performance, which contains millions of control points. The successful operation of this system will highly affect the machine performance. RHIC's successor, the Electron-Ion Collider (EIC), will be one of the most complex scientific instruments ever built, with the capability of colliding polarized proton and electron beams. The increasing complexity of instruments will require new, sophisticated control methods/tools to tune and optimize the accelerator performance. In this talk, I will summarize some projects developed in recent years that utilize machine learning in the C-AD controls group.
Biography: Dr. Yuan Gao is an assistant scientist at the Collider-Accelerator Department (C-AD) at Brookhaven, primarily working on developing new machine learning schemes in the control group to enhance system performance. His research interests include game theory, algorithm design, anomaly detection, and simulation modeling.
