InteractionBench: A Real-Time Interaction Benchmark for Streaming Video Systems
Enxin Song, Suhao Yu, Yifei Xu +7
A video assistant must speak when its instruction warrants a response and stay silent otherwise. We introduce a benchmark that evaluates this decision for the complete system of mo…
One Model, Two Roles: Emergent Specialization in a Shared Recurrent Transformer
Jucheng Shen, Barbara Su, Anastasios Kyrillidis
Can a shared-weight recurrent Transformer---one that repeatedly applies the same Transformer to update evolving latent states---develop distinct internal roles without being partit…
AdaPaD: Adaptive Parallel Deflation for PEFT with Self-Correcting Rank Discovery
Barbara Su, Fangshuo Liao, Anastasios Kyrillidis
Fine-tuning large language models with LoRA requires choosing a rank r before training starts. Existing approaches either extract rank-1 components sequentially, freezing each comp…
Exploiting Low-Rank Objective Structure in Discrete Quadratic Optimization
Ria Stevens, Fangshuo Liao, Barbara Su +3
We study the problem of maximizing a complex-valued quadratic form over the roots of unity. We show that when the objective matrix $\mathbf{Q}^\star \in \mathbb{C}^…
TwIST: Rigging the Lottery in Transformers with Independent Subnetwork Training
Michael Menezes, Barbara Su, Xinze Feng +3
We introduce TwIST, a distributed training framework for efficient large language model (LLM) sparsification. TwIST trains multiple subnetworks in parallel, periodically aggregates…
