What Does a Token Cost? A Mixture-of-Agents Measurement of Sufficient Per-Token Compute

Zhixu Du, Weijia Han, Hai Helen Li +1

Large language models spend the same amount of computation on every token they generate, regardless of how difficult each token is to produce. Methods such as speculative decoding…

DecodeShare: Tracing the Shared Subspace of LLM Decode-Time Decisions

Zishan Shao, Lixun Zhang, Kangning Cui +10

Large language models (LLMs) handle many tasks with one set of parameters, but under KV-cached inference it is unclear what task-general structure, if any, is used at decode time r…

Swimba: Switch Mamba Model Scales State Space Models

Zhixu Du, Krishna Teja Chitty-Venkata, Murali Emani +3

Mixture-of-experts (MoE) is a common approach for increasing parameter capacity, but applying MoE to state space model (SSM) token mixers can multiply the cost of the recurrent sta…

MoE-GPS: Guidlines for Prediction Strategy for Dynamic Expert Duplication in MoE Load Balancing

Haiyue Ma, Zhixu Du, Yiran Chen

In multi-GPU Mixture-of-Experts (MoE) network, experts are distributed across different GPUs, which creates load imbalance as each expert processes different number of tokens. Rece…

Robust and IP-Protecting Vertical Federated Learning against Unexpected Quitting of Parties

Jingwei Sun, Zhixu Du, Anna Dai +4

Vertical federated learning (VFL) enables a service provider (i.e., active party) who owns labeled features to collaborate with passive parties who possess auxiliary features to im…
