Pretraining Objective Shapes Cross-Category Generalization in Affective Image Prediction: A Geometric Comparison of Vision Transformer Encoders

This paper compares how different pretraining objectives affect the generalization of Vision Transformers in affective image prediction, finding that contrastive learning outperforms classification pretraining in cross-category generalization.

Precise Spatial Tuning of Visually Driven Alpha Oscillations in Human Visual Cortex

The paper measures alpha oscillations in human visual cortex using intracranial electrodes and finds they are spatially specific, with receptive field models showing larger spatial tuning compared to broadband power.
