CDS Seminar(23 August, 2019): Deceptive Media Manipulation – An arms race: Learning to defend & deceive
Fri, 23 Aug 19 @ 1:00 PM -- 2:00 PM
Department of Computational and Data Sciences
SPEAKER : Dr. Maneesh Kumar Singh (Verisk)
TITLE : “Deceptive Media Manipulation – An arms race: Learning to defend & deceive”
Date/Time : August 23,2019 (Friday) 1:00 PM
Venue : #102, CDS Seminar Hall.
As digital manipulation techniques get better, it is becoming increasingly difficult to distinguish between real and fake data. Being able to model the real world and generate realistic data has many exciting applications. However, it poses a serious challenge when such data is generated by malicious actors with an intent to deceive the user (or the computer
system) into believing that the fake data being generated is real. While such attacks on images have garnered much attention, they span across media types including speech & audio, text and, finally, fake news. To counter these attacks, intensive efforts have been undertaken by the ML community to generate effective defense strategies which malicious
adversaries, in turn, seek to circumvent. This has led to a virtual arms race.
In this talk, I will provide an overview of the recent efforts in my group at Verisk. We have focused on developing algorithms to defend against expert manipulation of images as well as adversarial attacks that can bypass such defenses. Most of this work is hot off the press and under review at various conferences.
Dr. Singh is Head R&D, Verisk | AI and the Director of the Human and Computation Intelligence Lab. His lab is working on creating collaborative (HMC, MMC) systems for efficient extraction of information & knowledge from unstructured data, capable of closed-loop & explainable reasoning and continuous learning, with applications in vision, NLP, speech and
