DESCRIPTION:\n*The seminar on 18.02. is cancelled. I will be postponed lat
 er in the term.*\n\nTraditionally\, AI and Machine Learning communities ha
 ve considered knowledge from the perspective of discrete vs continuous rep
 resentations\, knowledge bases (KBs) vs dense vectors or logic vs algebra.
  While these are important dichotomies\, in this talk I will argue that we
  should put more focus on another: parametric vs non-parametric modelling.
  Roughly\, in the former a fixed set of parameters is used\, in the latter
  parameters grow with data. I will explain recent advances in knowledge in
 tensive NLP from this perspective\, show the benefit of hybrid approaches\
 , and discuss KBs as non-parametric approaches with relatively crude assum
 ptions about what future information needs will be. By replacing these ass
 umptions with a learnt model\, we show that such “modern KBs” are a ve
 ry attractive alternative or complement to current approaches.   \n  \nBio
 : \n  \nSebastian Riedel is a researcher at Facebook AI research\, profess
 or in Natural Language Processing and Machine Learning at the University C
 ollege London (UCL) and an Allen Distinguished Investigator. He works in t
 he intersection of Natural Language Processing and Machine Learning\, and 
 focuses on teaching machines how to read and reason. He was educated in Ha
 mburg-Harburg (Dipl. Ing) and Edinburgh (MSc.\, PhD)\, and worked at the U
 niversity of Massachusetts Amherst and Tokyo University before joining UCL
