Structural reasoning, the ability to recognize and make inferences over the relational structure between objects and concepts, is a hallmark of human cognition, yet prevailing methods often collapse relational topology into flat embeddings, cannot discover hidden structure and lack interpretability. We introduce Neural...
Conditioned DFA (nDFA), a family that adapts established inverse-moment preconditioning to either side of this update, is studied, establishing practical benefits and important limits of conditioning learning with fixed random feedback.

Through a four-speaker attention decoding benchmark, it is shown that combining behavioral and physiological signals improves decoding performance over EEG-only approaches, enabling future advances in multimodal auditory attention decoding.

NeuronSifter treats decision quality as a property of the intervention interface, not of controller placement, and selects measurements by their expected reduction in intervention loss, assimilating typed outcomes into the same posterior.

Personal adaptation of three frozen EEG foundation models was evaluated in 235 held-out subjects in 235 held-out subjects from three motor-imagery datasets, comparing each subject's adapter with the population model and with adapters fitted to other subjects.
FAST-Brain is proposed, a unified flow-aligned spatio-temporal surrogate brain model that addresses all three challenges of resting-state functional magnetic resonance imaging data, and achieves state-of-the-art performance in recovering functional connectivity, effective connectivity, and the implicit low-dimensional...

The Temporal Simplicial Neural Network is introduced, which represents EEG recordings as sequences of evolving simplicial complexes, and jointly learns higher-order interactions and their temporal evolution by combining simplicial convolutions with recurrent updates.

A distribution-aware, information-theoretic measure of effective connectivity based on channel capacity under general residual distributions based on normalizing flows is introduced, and a principled distribution-aware framework for effective-connectivity estimation beyond Gaussian residual modeling is established.

This work introduces a symbolic distillation pipeline that converts trained neural likelihoods into explicit, interpretable expressions optimized for efficient parameter estimation, and uses a recovery-directed objective to guide symbolic regression toward expressions that preserve parameter-recovery accuracy.
The results suggest that depth and feedforward blocks enable transformers to implement adaptive inference, and this is advantageous when the distribution over latent variables has hierarchical structure.
A new model family (CortexMAE) trained using the masked autoencoder framework is introduced, and in this setting the CortexMAE family outperforms prior models by a large margin, and the first open evaluation suite (Brainmarks) for fMRI foundation models is released.
