Joint Fixed-Rate Universal Lossy Coding and Identification of Continuous-Alphabet Memoryless Sources
13 years 5 months ago
Abstract--The problem of joint universal source coding and density estimation is considered in the setting of fixed-rate lossy coding of continuous-alphabet memoryless sources. For...
