Decoding Naturalistic Speech from fMRI with Temporal Modeling and Multimodal Alignment

Reconstructing what a person perceives from their brain activity is a stringent test of whether neural recordings carry meaningful information. Naturalistic speech offers a rich testbed for this challenge: it unfolds over multiple timescales, but fMRI's noisy, temporally smeared measurements make this structure hard to...

Benchmarking External Generalization of SPD Matrix Learning for Resting-State fMRI Connectome Prediction

A reproducible age-prediction benchmark across six rs-fMRI datasets is introduced and provides common inputs, model settings, data splits, and analysis scripts so that future SPD matrix learning methods can be evaluated under the same external-validation protocol.
