UnverifiedSPERA has the potential to become a general-purpose pre-trained backbone for EEG analysis, provided its cross-device and cross-task generalization ability is validated in broader independent evaluations.69% similarUnverifiedParameter-Efficient Fine-Tuning (PEFT) is the core technical support for achieving low-cost training.68% similarUnverifiedA linear probe can be used for isolated validation: training only a single linear classifier on top of the frozen JEPA representations — if probe accuracy is high but control is 0% the problem lies in the actor, while low probe accuracy indicates the problem is in the JEPA training itself.68% similarUnverifiedBy projecting input activations onto a small subset of the principal components of the training distribution, probes can achieve cross-domain transfer with performance nearly matching that of probes trained directly on the test distribution.68% similar
