Tucker Attention: A generalization of approximate attention mechanisms

ICML 2026poster

The pursuit of reducing the memory footprint of the self-attention mechanism in multi-headed self attention (MHA) spawned a rich portfolio of methods, e.g., group-query attention (GQA) and multi-head latent attention (MLA). The methods leverage specialized low-rank factorizations across embedding di…

A geometric framework for momentum-based optimizers for low-rank training

NeurIPS 2025poster

Low-rank pre-training and fine-tuning have recently emerged as promising techniques for reducing the computational and storage costs of large neural networks. Training low-rank parameterizations typically relies on conventional optimizers such as heavy ball momentum methods or Adam. In this work, we…

Dynamical Low-Rank Compression of Neural Networks with Robustness under Adversarial Attacks

NeurIPS 2025oral

Deployment of neural networks on resource-constrained devices demands models that are both compact and robust to adversarial inputs. However, compression and adversarial robustness often conflict. In this work, we introduce a dynamical low-rank training scheme enhanced with a novel spectral regulari…

GeoLoRA: Geometric integration for parameter efficient fine-tuning

ICLR 2025poster

Low-Rank Adaptation (LoRA) has become a widely used method for parameter-efficient fine-tuning of large-scale, pre-trained neural networks. However, LoRA and its extensions face several challenges, including the need for rank adaptivity, robustness, and computational efficiency during the fine-tunin…

Structure Preserving Neural Networks: A Case Study in the Entropy Closure of the Boltzmann Equation

ICML 2022spotlight

In this paper, we explore applications of deep learning in statistical physics. We choose the Boltzmann equation as a typical example, where neural networks serve as a closure to its moment system. We present two types of neural networks to embed the convexity of entropy and to preserve the minimum…
