The computer science colloquium takes place on Mondays from 11:15 a.m. - 12:15 p.m.

This week's talk is a part of the Cray Distinguished Speaker Series. This series was established in 1981 by an endowment from Cray Research and brings distinguished visitors to the Department of Computer Science & Engineering every year.

This week's speaker, Daniel D. Lee (Cornell Tech), will be giving a talk titled "Geometry and Latent Representations in Machine Learnings".

Abstract

The advent of deep neural networks has brought significant advancements in the development and deployment of novel AI technologies. Recent large-scale neural network architectures have shown significantly better performance for object classification, segmentation, scene understanding and multimodal representations.  How can we understand how the representations of sensor input signals are transformed by deep neural networks? I will show how statistical insights can be gained by analyzing the high-dimensional geometrical structure of these representations as they are reformatted in neural network hierarchies.

This week's speaker, Ziyue Xu (Nvidia), will be giving a talk titled, "Federated Learning: Image, Language, and Beyond".

Abstract

Federated learning (FL) is a method used for training artificial intelligence models with data from multiple sources while maintaining data anonymity, thus removing many barriers to data sharing. In this talk, we will discuss two major aspects of FL: the research towards FL model development, and the tool needed to perform a real-life multi-institute FL study. Specifically, we will cover recent works on personalized FL, vertical FL, and client-contribution, and will illustrate the implementation of FL under various model settings using NVFlare - the NVIDIA Federated Learning Application Runtime Environment.

This week's speaker, Zhiqi (Woody) Bu (Amazon AWS AI), will be giving a talk titled, "On the Computational Efficiency of Differentially Private Deep Learning".

Abstract

Differentially private (DP) optimization is the standard paradigm to learn large neural networks that are accurate and privacy-preserving. The computational cost for DP deep learning, however, is notoriously heavy due to the per-sample gradient clipping. Existing DP implementations are 2−1000× more costly in time and space complexity than the standard (non-private) training. In this work, we develop a novel Book-Keeping (BK) technique that implements existing DP optimizers (thus achieving the same accuracy), with a substantial improvement on the computational cost. Specifically, BK enables DP training on large models and high dimensional data to be roughly as efficient as the standard training, whereas previous DP algorithms can be inefficient or incapable of training due to memory error. The computational advantage of BK is supported by the complexity analysis as well as extensive experiments on vision and language tasks. Our implementation achieves state-of-the-art (SOTA) accuracy with very small extra cost: on GPT2 and at the same memory cost, BK has 1.0× the time complexity of the standard training (0.75× training speed in practice), and 0.6× the time complexity of the most efficient DP implementation (1.24× training speed in practice). We will open-source the codebase for the BK algorithm.

This week's speaker, Yao-Yi Chiang (University of Minnesota), will be giving a talk titled, "Spatial AI and Its Applications in an Interdisciplinary World".

Abstract

Knowing what has happened, where and when, and how it has changed over space and time is the key to modeling complex spatiotemporal phenomena and understanding how humans depend on, adapt, and modify them. Today, many disciplines produce and use an increasing volume of data containing location and time information, either explicitly, e.g., mobility data, air quality data, satellite imagery, or implicitly, e.g., scanned historical maps and text documents. However, the substantial heterogeneity in these data coupled with inconsistencies in their spatiotemporal scales often result in existing methods focusing on a few data sources and treating the space and time dimensions as an afterthought, limiting their capability to solve critical problems. This talk will present recent highlights of our research results in Spatial Artificial Intelligence. The talk will present machine learning methods leveraging spatial science theories for predicting spatiotemporal phenomena and building a spatial language model to facilitate geospatial entity typing and linking. This talk will also outline our ongoing research directions in Spatial AI and interdisciplinary impact in public health, transportation, national security, geography, history, library, and digital humanities.

Talk Title: “Transforming Children’s Technologies through Developmentally Responsive Designs” By Dr. Saba Kawas

Abstract
Today's computing technologies—from smartphones to wearables to embedded computing—impact how children learn, play, communicate, and interact with others. Popular media and common wisdom often portray technology use by children as detrimental to their growth and well-being. However, in recent years, much research evidence in child-computer interaction, health, and education suggests that well-designed interactive technologies can have developmental and positive benefits for children and young adults' well-being. The overarching goals of my research are to draw theoretically-driven and research-based design considerations to account for adolescents' and children's developmental needs and overall well-being when designing technologies for them and to support designers in creating developmentally responsive technologies for children and adolescents. In this talk, I will describe a series of research studies that identify children's developmental needs and co-designing with children and adolescents different systems and tools to support their health and well-being. Based on the findings from this work, I will discuss pathways to bridge the Child-Computer Interaction research-practice gap.

Biography

Presentation title: “Research and Economic Development at the University at Buffalo”

Abstract:

As Vice President for Research and Economic Development, Dr. Govindaraju oversees the University at Buffalo’s diverse and broad-reaching research enterprise as well as the institution’s industry engagement. 

The university’s research program has launched a number of new opportunity areas, which Dr. Govindaraju will speak to. Among them includes a multi-million dollar, university-funded investment in high-end, cutting-edge equipment for use by researchers across campus. As well, a re-emphasized focus on the ever-strengthening international partnerships which focus on critical and emerging technology as well as collaboration within higher education. UB is home to “Communities of Excellence” – which aligns interdisciplinary teams of faculty, students and practitioners in diverse fields using research, education and engagement activities to create integrated solutions to issues – such as sustainable manufacturing and global health inequities. As well, Dr. Govindaraju launched the Buffalo Blue Sky program to provide funding for high-impact research that is structured to encourage cross-disciplinary partnerships to address “grand challenge” problems that are too complex for a single disciplinary approach.

A computer scientist, researcher and AI and machine learning expert, Dr. Govindaraju also will highlight UB’s recently created National AI Institute for Exceptional Education – funded by a $20M grant from the National Science Foundation and Institute of Education Sciences – for which he is PI and Director. Leaning into the positive impact pioneering AI can have on social good, the institute brings together the work of top-tier research scientists from nine institutions to address – drawing on AI as a key tool –the national shortage of speech-language pathologists. Dr. Govindaraju will share how the University at Buffalo, which is serving as the lead institution on the initiative, is elevating and prioritizing the work and future ambitions and opportunities of AI. Too, how the institute can serve as a model for cross-disciplinary and multi-institutional partnerships.
