DESCRIPTION:Prof. Shlomo Shamai The Viterbi Electrical and Computer Engine
 ering Faculty\, Technion\nThis presentation focuses on connections between
  relatively recent notions and variants of the\nInformation Bottleneck and
  classical information theoretic frameworks\, such as:\nRemote Source-Codi
 ng\; Information Combining\; Common Reconstruction\; The Wyner-Ahlswede-Ko
 rner Problem\;\nThe Efficiency of Investment Information\; CEO Source Codi
 ng under Log-Loss\,\nHypothesis Testing Error Exponent and others.\nWe ove
 rview the uplink Cloud Radio Access Networks (CRAN) with oblivious process
 ing\, which is\nan attractive model for future wireless systems and highli
 ght the basic connections to distributed\nGaussian information bottleneck 
 framework. For this setting\, the optimal trade-offs\nbetween rates (i.e.
   complexity) and information (i.e. accuracy) in the discrete and vector 
 Gaussian\nschemes is determined\, taking an information-estimation viewpoi
 nt.\nFurther\, the performance cost of the simple 'oblivious' universal pr
 ocessing in CRAN systems is\nexemplified via novel bounding techniques.\nT
 he concluding overview and outlook addresses in a unified way the dual pro
 blem of the\nprivacy funnel and recent observations on the additive noise 
 channels with a helper.\nConnections to the finite block length bottleneck
  features (related to the Courtade-Kumar conjecture)\nand entropy complexi
 ty measures (rather than mutual information) are shortly discussed.\nSome 
 challenging problems are mentioned such as the characterization of the\nop
 timal power limited inputs (`features') maximizing the `relevance' for the
  Gaussian\ninformation bottleneck\, under `complexity' constraints.\n-----

 \nThe talk is based mainly on joint research with A. Zaidi\, I.E. Auguerri
 \, G. Caire\, O. Simeone\nand S-H. Park.\nThe research of S. Shamai is sup
 ported by the European Union's Horizon 2020 Research and Innovation\nProgr
