Some recent work

A paper generalizing, establishing universality, and showing promise in LZ78-based information processing tasks:
A Family of LZ78-based Universal Sequential Probability Assignments
This paper also formed the basis for 1) our compression-based genomic classification pipeline with dramatic accuracy boosts and compute reductions relative to state‐of‐the‐art deepnets:
Genomic Data Classification via Universal Compression
as well as for 2) "GenAI" applications (e.g. symbolic music):
LZMidi: Compression-Based Symbolic Music Generation
and 3) sequential limited delay/lookahead estimation:
Universal Discrete Filtering with Lookahead or Delay
Adaptively trading off speed and accuracy when using LLM‐based models for time‐sensitive tasks:
Win Fast or Lose Slow: Balancing Speed and Accuracy in Latency-Sensitive Decisions of LLMs
A new diffusion framework replacing Gaussian noising with Poisson, providing sound theoretical guarantees and justification, as well as practical computational advantages and accuracy improvements:
ItDPDM: Information-Theoretic Discrete Poisson Diffusion Model
Compressed 2D Gaussian Splatting for efficient CLIP vision-language alignment:
Vision-Language Alignment from Compressed Image Representations using 2D Gaussian Splatting
A paper exploring entropic and statistical properties of the LZ78‐based sequential probability assignment (SPA) as an information source:
The LZ78 Source
Information‐computation trade‐offs in some highly non‐linear transforms:
Information-Computational Trade-offs in Non-linear Transforms
A Framework for Compressive On-chip Action Potential Recording
Pumiao Yan, Dante G. Muratore, E.J. Chichilnisky, Boris Murmann, and Tsachy Weissman
