Title: Latent Bridges for Multi-Table Question Answering
Abstract: GRAB is a lightweight latent bridge that encodes multi-table databases as relational graphs and injects query-conditioned structural tokens into frozen LLMs, significantly improving tabular reasoning without full fine-tuning.”

Title: Beyond Fixed Points: Superpolynomial Capacity of Asymmetric Hopfield Networks
Abstract: Classical Hopfield networks are limited to static patterns due to symmetric weights, whereas asymmetric networks can encode temporal sequences via limit-cycle attractors. Achieving high-capacity storage of long sequences in classical synchronous asymmetric networks, however, has remained a challenge. We present a simple and robust construction within the classical asymmetric Hopfield model with binary neurons and synchronous updates, that allows $n$ neurons to support $\exp\!\big(\Omega(n/(\log n)^2)\big)$ distinct limit-cycle attractors, each with period $\exp\!\big(\Omega(\sqrt n/\log n)\big)$ and robust to random noise with flip probability up to $\frac12-o(1)$, yielding superpolynomial capacity in both the number and length of stored sequences. This is the first demonstration of such capacity for asymmetric Hopfield networks, which we obtain by combining results from combinatorics, number theory and the analysis of opinion dynamics. Our findings show that synchronous asymmetric Hopfield networks possess a sequence-memory capacity which is larger and more robust than previously recognized, demonstrating that, in both biological and artificial neural systems, robust sequence representation can be achieved through coarse architectural motifs rather than complex nonlinearities.
11:30 - 11:50
Presentation by Shamik Basu, Ph.D. student (INRIA), Chair of Ezio Malis
Title: CAROL: Canonical Equivariant Network For Robot Localisation
Abstract: Localization in large-scale environments requires estimating a robot pose as a rigid-body transformation in SE(d) relative to a reference frame. In the absence of GPS,
global localization consists of aligning observations with a large-scale map without prior pose information. PR-by-PE methods address this task by directly regressing the pose.
However, most state-of-the-art approaches rely on decoupled pipelines that estimate rotation and translation sequentially, often projecting 3D geometry into lower-dimensional representations. This breaks the joint action of SE(d) and leads to error accumulation. We propose CAROL, an SE(d)-equivariant framework based on learned canonicalization of point sets and point clouds, enabling a unified treatment of vision and LiDAR data. After canonicalization, features are extracted with PointNet++ and lifted equivariantly to jointly perform place recognition and pose estimation. Experiments on the NCLT and Oxford RobotCar datasets show that CAROL improves localization success and precision over state-of-the-art PR-by- PE methods while maintaining comparable runtime
