DESCRIPTION:In this talk\, I will discuss the problem of lossy source codi
 ng under the logarithmic loss distortion measure. This distortion measure 
 is a natural choice in settings where the decoder (or decompressor) produc
 es a soft reconstruction of the source\, i.e.\, a probability distribution
 \, instead of a point estimate. I will focus on block-coding in discrete m
 emoryless settings\, and present new results on the error exponent under a
 n excess distortion constraint. I will then extend the results to settings
  with side information. The proofs are based on the method of types\; and 
 make use of the close relationship between lossy source coding under logar
 ithmic loss\, and almost lossless source coding with list decoding.\n\n
