Memory-Augmented Spiking Networks: Synergistic Integration of Complementary Mechanisms for Neuromorphic Vision

This paper demonstrates that synergistically integrating Supervised Contrastive Learning, Hopfield networks, and Hierarchical Gated Recurrent Networks into Spiking Neural Networks achieves optimal neuromorphic vision performance on N-MNIST by balancing accuracy, energy efficiency, and structured neuronal clustering, rather than relying on isolated architectural optimizations.

Robust Parameter and State Estimation in Multiscale Neuronal Systems Using Physics-Informed Neural Networks

This paper presents a physics-informed neural network (PINN) framework that robustly reconstructs hidden state variables and estimates biophysical parameters in multiscale neuronal models using only partial, noisy voltage observations, effectively overcoming the convergence failures and sensitivity issues common in traditional numerical methods.

Permutation-Equivariant 2D State Space Models: Theory and Canonical Architecture for Multivariate Time Series

This paper introduces the Variable-Invariant Two-Dimensional State Space Model (VI 2D SSM) and its unified VI 2D Mamba architecture, which theoretically establish and implement a permutation-equivariant framework for multivariate time series that eliminates artificial variable ordering to achieve state-of-the-art performance with improved structural scalability.

Generalized Reduction to the Isotropy for Flexible Equivariant Neural Fields

This paper introduces a principled method to reduce GG-invariant functions on product spaces X×MX \times M to HH-invariant functions on XX alone, where HH is the isotropy subgroup of MM, thereby enabling flexible Equivariant Neural Fields to handle arbitrary group actions and heterogeneous product spaces without structural constraints.
