DESCRIPTION:"Enabling Perception-Driven Optimization for Internet Video"\n\
 nThe landscape of online applications has changed significantly\, with the 
 rise of interactive videos in daily remote learning and meetings\, and the 
 proliferation of AI applications that stream video sensor data to machine-l
 earning models rather than human viewers\, to make our cities safer and bus
 inesses more intelligent. The result is more video data and higher expectat
 ions of video quality\, dramatically increasing the resource demands in net
 work and compute. We argue that a driving contributor is that today's video
  systems try to optimize performance metrics (latency\, buffering ratio\, e
 tc) everywhere. Instead\, video systems should be built to directly optimiz
 e user experience (in terms of engagement of human viewers and accuracy of 
 ML models). Through large-scale measurements and user studies\, we show tha
 t users' sensitivity to traditional system performance metrics varies spati
 ally and temporally more than previously believed. These findings have insp
 ired new network system designs that improve the scale and user experience 
 for human-centric applications (e.g.\, Internet videos) and AI-centric appl
 ications (e.g.\, video analytics).\n\n \n\nSpeaker Bio\n\nJunchen Jiang is 
 an Assistant Professor of Computer Science at the University of Chicago. He
  received his PhD degree from CMU in 2017 and his bachelor's degree from Ts
 inghua in 2011. His research interests are networked systems\, multimedia s
 ystems\, and their intersections with machine learning. He is a recipient o
 f a Google Faculty Research Award\, NSF CAREER Award\, and CMU Computer Sci
 ence Doctoral Dissertation Award.
