MIMOMamba: From Scalar Duality to Matrix-Valued Attention

ICML 2026poster

The state space duality (SSD) framework, central to modern state-space models (SSMs) such as Mamba, has established an efficient attention-like mechanism by leveraging the commutative property of linear recurrences. However, existing formulations are limited to single-input single-output (SISO) syst…

Adaptive Kernel Design for Bayesian Optimization Is a Piece of CAKE with LLMs

NeurIPS 2025poster

The efficiency of Bayesian optimization (BO) relies heavily on the choice of the Gaussian process (GP) kernel, which plays a central role in balancing exploration and exploitation under limited evaluation budgets. Traditional BO methods often rely on fixed or heuristic kernel selection strategies, w…

Demystifying Model Averaging for Communication-Efficient Federated Matrix Factorization

ICASSP 2021accepted

Federated learning (FL) is encountered with the challenge of training a model in massive and heterogeneous networks. Model averaging (MA) has become a popular FL paradigm where parallel (stochastic) gradient descent (GD) is run on a small sampled subset of clients multiple times before uploading the…
