MS Thesis Defense - Chia-wei Tang
by Thomas, Chris 30 Apr '24

30 Apr '24

Hello, You are invited to attend Chia-wei Tang's MS thesis defense Wednesday, May 1st. Title: M3D: MultiModal MultiDocument Fine-Grained Inconsistency Detection Date: May 1, 2024 Time: 1:00pm Location: Online Zoom: https://virginiatech.zoom.us/j/8956885181 Committee members: Chris Thomas (Chair), Lifu Huang (Member), Ismini Lourentzou(Member) Abstract: Fact-checking claims is a highly laborious task that involves understanding how each factual assertion within the claim relates to a set of trusted source materials. Existing approaches make sample-level predictions but fail to identify the specific aspects of the claim that are troublesome and the specific evidence relied upon. In this thesis, we introduce a method and new benchmark for this challenging task. Our method predicts the fine-grained logical relationship of each aspect of the claim from a set of multimodal documents, which include text, image(s), video(s), and audio(s). We also introduce a new benchmark of claims requiring multimodal multi-document reasoning, which we construct using a novel claim synthesis technique. Experiments show that our approach significantly outperforms state-of-the-art baselines on this challenging task on two benchmarks while providing finer-grained predictions, explanations, and evidence.

Reminder about Zoom and Prelims/Defenses
by Shaffer, Cliff 30 Apr '24

30 Apr '24

I want to remind everyone that Final Defenses and Prelim Exams are (obviously) official University events with Grad School rules. In particular, these invariably involve a private discussion by the committee. Therefore, students are not permitted to set up the Zoom meeting if you are using Zoom. This needs to be set up by the committee chair or appropriate designated person, so as to guarantee the integrity of the private portion of the meeting. Sorry for any inconvenience that this might cause, but that's the rule. -- Dr. Cliff Shaffer Professor and Associate Department Head for Graduate Studies Department of Computer Science Phone: (540) 231-4354 Virginia Tech, Blacksburg, VA 24061 WWW: www.cs.vt.edu/~shaffer<http://www.cs.vt.edu/~shaffer>

[PhD Students] For PhD students who have not taken the qualifier exam
by Shaffer, Cliff 29 Apr '24

29 Apr '24

Recently, the faculty voted to slightly modify the PhD qualifier process. The modification only affects students who are either (1) currently in their first year or (2) otherwise have not yet taken the qualifier exam. For those who already have an exam score (or anyone who has already arranged with me to be given 3 points for their research), the old rules apply. Under the old rules, students would take the exam (or not) and separately request an interpretation of their research points from the Graduate Program Director. With the changes now in place, all assessments for the Depth portion of the exam (that is, the requirement to receive 3 points from a combination of the exam and research) will be made by the PhD Qualifier Exam Committees. As part of signing up for the PhD qualifier exam (typically in late Fall), a student is to apply to a Qualifier Exam Committee in their research area. The committee will determine (1) student research points, and, when needed, (2) examination points (exams are typically given in Spring). As in the current system, the committee might waive the exam, granting a student all 3 points for their prior research. The Qualifier Exam Committee will ultimately render a pass or fail decision for each student applying to their committee regarding the depth portion of the exam, based on a holistic view of their research productivity and (when appropriate) their Qualifier exam score. Students who do not pass their first attempt will be given a second attempt the following year. But note that to be eligible for the second attempt, one has to take the exam “on time” (in your second Spring semester), unless granted an explicit postponement. -- Dr. Cliff Shaffer Professor and Associate Department Head for Graduate Studies Department of Computer Science Phone: (540) 231-4354 Virginia Tech, Blacksburg, VA 24061 WWW: www.cs.vt.edu/~shaffer<http://www.cs.vt.edu/~shaffer>

MS Defense (5/3, 11:30, 4211 Gilbert) on MLPerf PowerPack
by Cameron, Kirk 29 Apr '24

29 Apr '24

Hi Everyone, Please see below information for Cesar Smokowski’s MS defense on Friday (May 3) in Room 4211 of Gilbert Place. There is also a zoom option though many of us will be there in person. Please share as you see fit. I hope you can join! Best, -kwc Title: MLPerf PowerPack: Defining MLPerf Inference Benchmark’s Power Profile Date: Friday, May 3, 2024 Time: 11:30am Location: Room 4211, Gilbert Place Zoom: https://virginiatech.zoom.us/my/cesar8800 Committee members: Kirk Cameron (Chair), Godmar Back (Member), Margaret Ellis (Member) Abstract: This thesis project investigates the energy consumption of individual system components during the execution of MLPerf Inference, an industry-standard benchmark suite for assessing the performance of the machine learning inference phase. The power profile of MLPerf Inference was formulated using the PowerPack framework, a collection of hardware components, including external power meters and resistors, and software tools, including benchmarks and libraries, designed to directly measure the power consumption of system components. Software power measurement tools, AMDuProf and NVIDIA-SMI, were used to compare the accuracy of PowerPack’s power consumption measurements for the CPU and GPU, respectively. The energy consumption distribution amongst the system’s CPU, GPU, and disk was tested for the NAS Parallel Benchmark (NPB) FT benchmark and the MLPerf Inference image classification benchmark. The updated MLPerf PowerPack toolkit varied within 86% to 97% accuracy when compared to AMDuProf and NVIDIA-SMI’s, native software-based power measurement tools. The MLPerf PowerPack framework was also used to identify the CPU, GPU, and disk energy consumption for the seven major functions of MLPerf Inference’s image classification benchmark. Bio: Cesar Smokowski is a Master’s student in the Department of Computer Science. He is working under the supervision of Dr. Cameron in the SCAPE Laboratory. Cesar graduated from Virginia Tech with his Bachelor’s of Science in Computer Science in 2022. Cesar’s research interests include energy efficiency and machine learning, and Cesar will join Amazon full time in summer 2024.

Ano Shukla's Master's thesis defense, Monday 4/29 3pm
by Stephen H Edwards 25 Apr '24

25 Apr '24

Dear all, You're cordially invited to Anmol "Ano" Shukla's Master's thesis defense. *Title*: *Investigating Student Perceptions of Equitable Grading Practices* *Date*: Monday, April 29, 2024 *Time*: 3:00 pm *Location*: Torgersen 1210 *Zoom*: https://virginiatech.zoom.us/j/89473192702?pwd=SzZoRWNjVEt0ZXJYNk9kQUxUSmhl… *Abstract*: Grading is one of the key components of modern pedagogy. Grades are primarily meant to be a method of communication, which is initiated by the owners of the pedagogy (instructors, school, etc.) and are received by various parties such as students: as feedback on their learning outcomes, parents, potential employers, other institutions, etc. However, traditional grading practices in wide use across institutions globally suffer from many problems and can prove to be a hindrance to students achieving their learning outcomes. Many of these practices do not have a backing in education and social research and suffer from various problems such as inherent bias, rewarding of behavior over skill or knowledge, increasing student anxiety, etc. To mitigate some of these problems, we employ Equitable Grading Practices (EGPs) in an introductory CS-1 course at Virginia Tech for the Fall 2023 and Spring 2024 semesters. In contrast, EGPs have been backed in research, follow a more open assessment method and have been shown to induce increased learning. In this thesis, we introduce these practices and evaluate student perceptions of them thereafter to answer research questions so that we may be able to refine these practices. We gather student experiences primarily through two instruments: a survey and one-on-one interviews. We describe these in detail and evaluate them through the use of statistics as well grounded theory analysis to be able to extract student perceptions of these grading practices. -- Steve --------------------------------------------------------------------------- Virginia Tech, CS Dept.

Mr. Sandeep Chinnareddy’s Master thesis defense
by Liqing Zhang 25 Apr '24

25 Apr '24

Dear all, You're cordially invited to join Mr. Sandeep Chinnareddy's Master's defense. Detailed information is below. *Title*: *Applications of Machine Learning in Source Attribution of Pathogens* *Date*: Friday, April 26, 2024 *Time*: 2:00 pm *Zoom*: https://virginiatech.zoom.us/j/8790572835 <https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fvirginiat…>. This meeting will be zoom only for non-committee members. *Committee members*: Song Li (Co-Chair), Jingqiu Liao (Co-Chair), Liqing Zhang (Member), Xuan Wang (Member) *Abstract*: This research investigates the application of machine learning techniques in computational genomics for the prediction of bacterial pathogen hosts using genomic sequences. This work describes the development of a novel bioinformatics pipeline for assembling the Gene Presence-Absence and single nucleotide polymorphism datasets from genomic assembly IDs. This methodology is applied to specific animal pathogen *Salmonella enterica* serovar Typhimurium. Phylogenetic analyses along with pan-genome and positive selection studies provide the foundational motivation for employing machine learning models. We benchmarked seven traditional machine learning algorithms, achieving a notable accuracy of 94.6% in host prediction for S. Typhimurium using the Random Forest model, underscored by SHAP value analyses which identified the most important genes and their corresponding functions. Further, this pipeline is extended to plant pathogens, *Ralstonia solanacearum* species complex to achieve an accuracy of 76% using the LightGBM model. *Bio:* Sandeep Chinnareddy is a Master’s student in the Department of Computer Science. He is working under the supervision of Dr. Song Li and Dr. Jingqiu Liao, in Li Lab of Applied Machine Learning in Genomics and Phenomics and Liao Environmental and Public Health Microbiology (LEAPH) Lab. Sandeep received his Bachelors in Electronics and Communication Engineering and a Masters in Biological Sciences from Birla Institute of Technology and Sciences (BITS) Pilani. Sandeep’s research interests include computational genomics and deep learning. Best, Song Li
