DDoS: a 20-year journey from compromised workstations to IoT attacks

Sven Dietrich

Math & Computer Science Dept.

John Jay College of Criminal Justice

April 11, 12pm-1pm

Room N923


In this 20-year retrospective, we discuss some of the challenges of dealing with distributed denial-of-service (DDoS) attacks from its origins in 1999 to the recent attacks in the late 2010s.  We describe first architectures of DDoS agents, the challenges of DDoS agent/bot forensics, the variety of topologies and command-and-control mechanisms for botnets over the years, the different victim populations from scientific workstations to IoT devices, future and current Internet design considerations, as well as attack and defense mechanisms at the host and network levels.




Building noise robust machine listeners with data and inspiration from humans

Michael Mandel

Associate Professor

Brooklyn College, Graduate Center

November 8, 12pm-1pm

Room N919


Matching human performance is one of the most difficult problems for a variety of speech communication technologies, including automatic speech recognition, voice processing in hearing aids, and mobile telephony.  One theory of human noise robustness is that listeners pick out reliable “glimpses” of a target sound and utilize contextual clues to fill in missing information using top-down knowledge.  This talk presents work that brings both of these processes to machines.



Driving Enterprise Transformation with Virtual & Augmented Reality

October 11, 12pm-1pm
Room N919


Enterprises are embracing Virtual and Augmented Reality, using VR and AR to transform the way businesses work, train their staff, collaborate, communicate and interact with clients. We will examine the current trend of VR and AR usage from different industries such as Aviation, Automobile and Retail with a specific emphasis on use cases for the Architectural, Engineering and Construction industry.



Eager Execution in TensorFlow

Alexandre Passos

Software Engineer Google

April 12, 12pm-1pm Room N923





In this talk we’ll go over TensorFlow, an open- source cross-platform machine learning library developed by Google, and explore its new feature: eager execution. We’ll go over how to use it to write dynamic models, to debug and profile models, and to learn deep learning.
