Universal Variable-to-Fixed Length Lossy Compression at Finite Blocklengths
Nematollah Iri
We consider universal variable-to-fixed length compression of memoryless sources with a fidelity criterion. We design a dictionary codebook over the reproduction alphabet which is…

Type Size Code for Compressing Erdös-Rényi Graphs
Nematollah Iri
We consider universal source coding of unlabeled graphs which are commonly referred to as graphical structures. We adopt an Erdös-Rényi model to generate the random graphical struc…

Fundamental Limits of Universal Variable-to-Fixed Length Coding of Parametric Sources
Nematollah Iri, Oliver Kosut
Universal variable-to-fixed (V-F) length coding of -dimensional exponential family of distributions is considered. We propose an achievable scheme consisting of a dictionary, us…
