DeltaProduct: Improving State-Tracking in Linear RNNs via Householder Products

NeurIPS 2025poster

Linear Recurrent Neural Networks (linear RNNs) have emerged as competitive alternatives to Transformers for sequence modeling, offering efficient training and linear-time inference. However, existing architectures face a fundamental trade-off between expressivity and efficiency, dictated by the stru…

Unlocking State-Tracking in Linear RNNs Through Negative Eigenvalues

ICLR 2025oral

Linear Recurrent Neural Networks (LRNNs) such as Mamba, RWKV, GLA, mLSTM, and DeltaNet have emerged as efficient alternatives to Transformers for long sequences. However, both Transformers and LRNNs struggle to perform state-tracking, which may impair performance in tasks such as code evaluation. In…

Bayesian Optimization-Based Combinatorial Assignment

AAAI 2023technical

We study the combinatorial assignment domain, which includes combinatorial auctions and course allocation. The main challenge in this domain is that the bundle space grows exponentially in the number of items. To address this, several papers have recently proposed machine learning-based preference e…

Monotone-Value Neural Networks: Exploiting Preference Monotonicity in Combinatorial Assignment

IJCAI 2022poster

Many important resource allocation problems involve the combinatorial assignment of items, e.g., auctions or course allocation. Because the bundle space grows exponentially in the number of items, preference elicitation is a key challenge in these domains. Recently, researchers have proposed ML-base…

NAS-Bench-1Shot1: Benchmarking and Dissecting One-shot Neural Architecture Search

ICLR 2020poster

One-shot neural architecture search (NAS) has played a crucial role in making NAS methods computationally feasible in practice. Nevertheless, there is still a lack of understanding on how these weight-sharing algorithms exactly work due to the many factors controlling the dynamics of the process. In…
