Conferences, Lectures, & Seminars
Speaker: Dr. Huan Liu , Regents Professor and Ira A. Fulton Professor of Computer Science and Engineering - Arizona State University
Talk Title: Ceaseless Inquiries: From AI to AI - What I Learned During My Years at USC under Dr. Bekey and What Came After
Abstract: My time at USC as a graduate student, with Dr. George Bekey as my advisor, had an indelible impact on my career. In this talk, I will illustrate how my research career was shaped by Dr. Bekey’s supervision and the ambience at USC at the time. My research journey in AI began in Robotics, and evolved into Knowledge-based Systems, Machine Learning, Data Mining, Social Computing, and Social Media Mining with posts in Australia, Singapore, and finally in the US, where I now teach at ASU. On the shoulders of giants, I learned valuable lessons on how to be an effective advisor and what the essence of research is. With the swift development of AI, we will have many more research opportunities to make novel contributions at accelerating speeds.

Title: Performance Modeling and Optimization for Machine Learning Systems: from Cloud Training to Edge Inference
Date and Time: Fri, April 25, 2-4pm
Location: EEB 403
Committee Members: Leana Golubchik (Chair), Murali Annavaram, Peter Beerel, Jyotirmoy V. Deshmukh, William G. J. Halfond
Abstract: Deep neural networks (DNNs) have achieved remarkable success in a wide range of tasks, from computer vision to natural language processing. However, as these networks substantially grow in scale, ensuring efficient performance across the entire lifecycle - from cloud-based training to edge-device inference - remains a crucial problem. Our work addresses this need by developing performance modeling and optimization techniques for both cloud-based distributed training and edge-based inference.
First, we develop training throughput prediction models (coarse-grained and fine-grained) for distributed stochastic gradient descent (SGD), characterizing the impact of communication bottlenecks and node stragglers in synchronous/asynchronous and centralized/decentralized settings. Second, we propose an operation-wise framework that accurately predicts the inference latency of various neural architectures - such as CNNs and Vision Transformers (ViTs) - across diverse mobile platforms and ML frameworks. Finally, we propose a heterogeneous co-execution approach that combines low-overhead synchronization with ML-based workload partitioning on mobile CPUs and GPUs, substantially speeding up inference tasks. Together, these three contributions form a comprehensive methodology for end-to-end DNN performance evaluation and optimization, providing practical insights for large-scale training in the cloud and efficient deployment at the edge.Location: Hughes Aircraft Electrical Engineering Center (EEB) - 403

Title of Thesis Proposal: AI-Mediated Dispute Resolution
Date and Time: Friday 25 April 2025 3-5PM
Location: GCS 402C
Committee Members: Dr. Jonathan Gratch, Dr. Gale Lucas, Dr. Jesse Thomason, Dr. Laurent Itti, and Dr. Peter Kim
Abstract: When conflict arises so does the possibility of potentially irreparable harm interpersonally, policitally, or professionally. Simultaneously, finding effective mediators, especially for those without the means to hire an expert, remains a challenge and may preclude resolution. In this proposal, I examine whether one can leverage recent advances in artificial intelligence to create automated mediators -- democratizing conflict mediation. First, I present a laboratory setting wherein we induce conflict in dyads of human crowd workers as they roleplay a buyer-seller dispute -- yielding the KODIS corpus. Second, we examine whether LLMs can understand emotion dynamics in KODIS to forecast dispute outcomes -- showing they can predict subjective outcomes, and uncovering escalatory spirals as the literature predicts. Lastly, I outline my plan to create automated mediators over the remainder of my PhD.Location: Henry Salvatori Computer Science Center (SAL) - 213
