LiVeAction: a Lightweight, Versatile, and Asymmetric Neural Codec Design for Real-time Operation

Researchers introduced LiVeAction, a lightweight asymmetric neural codec for real-time, resource-constrained compression.

It simplifies the encoder with an FFT-like structure and replaces adversarial/perceptual losses with a variance-based rate penalty.

The method achieves better rate-distortion performance than state-of-the-art generative tokenizers across diverse signal types.

LiVeAction is aimed at practical deployment on low-power devices such as sensors, where efficiency matters most.
