Study Recruitment: Interaction Study with a Presentation System
by Keelawat, Panayu 17 Feb '25

17 Feb '25

Dear all, The Programming with Intelligent Machines & Environments Lab (PRIME Lab) at Virginia Tech is seeking individuals to participate in a 30-minute in-person study focused on exploring interaction techniques for preparing presentation materials from classroom discussions. We are specifically looking for individuals with teaching experience (e.g., instructors, UTAs, GTAs, etc.) who have prepared presentation materials for a class. In this study, participants will interact with simulated discussion and use multimodal inputs (e.g., voice and gestures) to generate, refine, and update slide content. Participants will be compensated $15 for their time and effort upon completion of the study. The research protocol for this study has been reviewed and approved by the Virginia Tech Institutional Review Board (IRB #24-1020). If you are interested in participating, please fill out the form: https://forms.gle/fwewxb4c2Aqi7fd76 If you have any questions or would like to know more about the study, please don’t hesitate to reach out. For more information, please contact Panayu Keelawat (panayu(a)vt.edu<mailto:panayu@vt.edu>). This study is being conducted under the supervision of Dr. Yan Chen (ych(a)vt.edu<mailto:ych@vt.edu>).

invitation to Atul Bharadwaj's MS thesis defense, 2:00 PM on Wednesday, February 19
by Lenwood S. Heath 17 Feb '25

17 Feb '25

You are invited to Atul Bharadwaj's MS thesis defense, 2:00 PM on Wednesday, February 19, in 1210 Torgersen. The abstract for the defense is below. There is no Zoom option; just drop in! -- Lenwood S. Heath Professor 2160J Torgersen Hall Department of Computer Science Cell phone: (540) 392-6672 Virginia Tech FAX: (540) 231-6075 Blacksburg, VA 24061-0106 Email: heath(a)vt.edu -------------------------------------------------------------------------- Message and signature (c)2025 Lenwood S. Heath All rights reserved -------------------------------------------------------------------------- COVID-19 Variant Detection through Genomic Sequences and Jaccard Similarities Atul Bharadwaj The COVID-19 pandemic has underscored the urgent need for efficient genomic surveillance to track the emergence and spread of SARS-CoV-2 variants. This study developed a computational framework to enhance variant detection by leveraging a database-driven approach and genomic sequence analysis. The framework utilizes MySQL database architecture where each variant is stored in distinct tables, enabling rapid comparison and classification of new variants through Jaccard similarity calculations. The approach employs advanced bioinformatics tools including Sourmash for signature generation and NumPy for computational analysis, alongside Python-MySQL connectors for seamless database interactions. The system implements similarity thresholds of 0.817 for primary classification and 0.867 for secondary validation to determine variant group membership. Both whole-genome and spike-only sequence data were analyzed to compare their effectiveness in identifying variants of concern, with the database structure accommodating both types of genomic data. The results demonstrated the framework's ability to accurately detect and classify SARS-CoV-2 variants with high sensitivity and specificity. When a new variant is introduced, the system calculates Jaccard similarity scores between the new variant and existing variant tables, automatically creating new tables for potentially novel variants that fall below-established similarity thresholds. The study highlighted the potential of spike-only sequences as a cost-effective alternative for variant detection in resource-limited settings, while also revealing their limitations compared to whole-genome analysis. This research contributes to global genomic surveillance efforts by providing scalable database tools for rapid variant identification, aiding public health strategies, vaccine development, and therapeutic interventions.

PhD Final Defense for Frank Wanye: Fast & Accurate Graph Clustering
by Wuchun Feng 16 Feb '25

16 Feb '25

I am pleased to invite you to attend the PhD Final Defense for Frank Wanye, as articulated below. When: Monday, February 17 at 3:00 p.m. Where: Torgersen 2050 or via Zoom @ https://virginiatech.zoom.us/my/wfeng What: Fast and Accurate Graph Clustering Graph clustering, also known as community detection, is a fundamental problem in graph analytics with applications across a wide variety of domains including bioinformatics, social media analysis, and anomaly detection. Graph clustering algorithms can be grouped into two categories: inferential and descriptive. While inferential algorithms deliver high accuracy, they also deliver poor performance and poor scalability, particularly on large graphs. Conversely, descriptive algorithms are fast and scalable but significantly less accurate. We focus on accelerating the performance and improving the scalability of stochastic block partitioning (SBP), an inferential graph-clustering algorithm based on sequential Bayesian inference. Like other inferential algorithms, SBP is highly accurate even on graphs with a complex community structure, but it does not scale well to large real-world graphs that can contain upwards of a million vertices. Our contributions center around developing novel approaches for accelerating SBP, namely data reduction via sampling, shared-memory parallelization, and distributed-memory parallelization. We then integrate these approaches into a unified, accelerated SBP implementation, which exhibits up to 322-fold speedup over sequential SBP on a one-million vertex graph when processed on 64 compute nodes with 128 cores each. Importantly, our approach accelerates SBP without sacrificing the algorithm’s accuracy on both real-world and synthetic graph datasets. ~~ Wu FENG | Synergy Lab | Depts. of CS, ECE, BEAM | NSF SHREC Center & SEEC Center at Virginia Tech | Professor, Turner Faculty Fellow, and Director | 2050 Torgersen Hall | 620 Drillfield Drive | VT | Blacksburg VA 24061 | 540-231-1192 | wfeng(a)vt.edu
