List-Level Distribution Coupling with Applications to Speculative Decoding and Lossy Compression

Joseph Rowan, Buu Phan, Ashish Khisti

We study a relaxation of the problem of coupling probability distributions -- a list of samples is generated from one distribution and an accept is declared if any one of these sam…

On Self-Adaptive Perception Loss Function for Sequential Lossy Compression

Sadaf Salehkalaibar, Buu Phan, Likun Cai +4

We consider causal, low-latency, sequential lossy compression, with mean squared-error (MSE) as the distortion loss, and a perception loss function (PLF) to enhance the realism of…

Robust Federated Finetuning of LLMs via Alternating Optimization of LoRA

Shuangyi Chen, Yuanxin Guo, Yue Ju +3

Parameter-Efficient Fine-Tuning (PEFT) methods like Low-Rank Adaptation (LoRA) optimize federated training by reducing computational and communication costs. We propose RoLoRA, a f…

Robust Federated Finetuning of Foundation Models via Alternating Minimization of LoRA

Shuangyi Chen, Yue Ju, Hardik Dalal +2

Parameter-Efficient Fine-Tuning (PEFT) has risen as an innovative training strategy that updates only a select few model parameters, significantly lowering both computational and m…
