  CS Colloquium - Aastha Mehta - "Policy Compliance in Online Services"

  Department of Computer Science

  12:00 PM Room 3514, Mudd Hall ( formerly Seeley G. Mudd Library)

  EVENT DETAILS

  Title: Policy Compliance in Online Services

  Abstract

  In response to incidents of unintended disclosure and misuse of user data by online services, modern data protection regulations require service providers to restrict their collection, processing, sharing and storage of sensitive user data. However, ensuring compliance with such regulation in today's complex and rapidly evolving systems is technically challenging. In my research, I have developed practical systems to prevent unintended disclosures and misuse of data in the face of two broad classes of threats: software bugs and misconfiguration, and side channels.In this talk, I will describe Pacer, a compliance system designed to prevent indirect inference of sensitive data via side channels in shared network links in the Cloud. Pacer shapes the outbound traffic of a Cloud tenant to make it independent of the tenant's secrets. At the same time, Pacer does allow variations in the traffic shape based only on public (non-secret) aspects of the tenants' workloads, thus enabling efficient sharing of network resources and incurring moderate overhead. Implementing Pacer requires modest changes to the Cloud hypervisor and the guest OS, and minimal changes to the guest application.

  CS Seminar: AI Powered Movement Analysis, Big Rehabilitation Data and a Path to Precision Rehabilitation (R. James Cotton)

  Department of Computer Science (CS)

  EVENT DETAILS

  Speaker
  R. James Cotton, Northwestern University & Shirley Ryan AbilityLab

  Talk Title
  AI Powered Movement Analysis, Big Rehabilitation Data and a Path to Precision Rehabilitation

  Abstract
  This talk will discuss multiple methodological lines of work making movement and gait analysis more clinically accessible and biomechanically grounded. This includes reconstruction from synchronized multiview videos, smartphone videos, and wearable sensors. We will also discuss how implicit functions provide a powerful representation to map from time to joint angles, and GPU accelerated methods that enable end-to-end biomechanical fits from these different modalities. It will discuss some of the opportunities that large movement data enables, including the use of self-supervised learning to discover gait representations that can function as both diagnostic and response biomarkers. Finally, we will outline a vision for a Causal Framework for Precision Rehabilitation that can model this data to link from impairment to function and identify the optimal dynamic treatment policies to improve rehabilitation outcomes.

  Biography
  I am an electrical engineer, neuroscientist, and physiatrist working as a physician-scientist at Shirley Ryan AbilityLab and Assistant Professor in the Northwestern University Department of Physical Medicine and Rehabilitation. I completed my residency in PM&R at Shirley Ryan AbilityLab (formers Rehabilitation Institute of Chicago) where I remained as faculty. Prior to that I obtained a B.S. in Electrical Engineering from Rice University followed by an MD and PhD in systems neuroscience from Baylor College of Medicine. My lab works at the intersection of artificial intelligence, wearable sensors, computer vision, causal and biomechanical modeling, and novel technologies to more precisely monitor and improve rehabilitation outcomes.

  Research Area/Interests

  Speaker
  Kaize Ding, Northwestern University

  Talk Title
  Data-Efficient Graph Learning
  
  Abstract
  The world around us -- and our understanding of it -- is rich in relational structure: from atoms and their interactions to objects and entities in our environments. Graphs, with nodes representing entities and edges representing relationships between entities, serve as a common language to model complex, relational, and heterogeneous systems. Despite the success of recent deep graph learning, the efficacy of existing efforts heavily depends on the ideal data quality of the observed graphs and the sufficiency of the supervision signals provided by the human-annotated labels, leading to the fact that those carefully designed models easily fail in resource-constrained scenarios.

  In this talk, I will present my recent research contributions centered around data-efficient learning for relational and heterogeneous graph-structured data. First, I will introduce what data-efficient graph learning is and my contributions to different research problems under its umbrella, including graph few-shot learning, graph weakly-supervised learning, and graph self-supervised learning. Based on my work, I will elucidate how to push forward the performance boundary of graph learning models especially graph neural networks with low-cost human supervision signals. I will also touch upon the real-world applications of data-efficient graph learning to different domains and finally conclude my talk with a brief overview of my future research agenda.

  Talk Title
  Trust, Backdoor Vulnerabilities and Possible Mitigations

  Abstract
  Cryptographic tools and models enable to trust the use of technology platforms controlled by worst case computationally bounded adversaries. In this talk I will use cryptographic modeling and tools to view trust dilemmas in various phases of the machine learning pipelines. We will touch on privacy in the training stage, verification of properties of
  machine learning models, and the possibility of achieving robustness in presence of backdoors.
