A new study utilizing the TRIBE model, a combination of Llama-3.2, V-JEPA2, and Wav2Vec-BERT, found that predicted neural signals from fMRI data do not accurately forecast viewer engagement on YouTube. Researchers analyzed engagement curves derived from TRIBE's predicted cortical responses against "most replayed" heatmaps for 48 YouTube videos. The results showed no significant correlation, indicating that the model's predictions do not align with viewer re-watch behavior, even when controlling for factors like loudness and motion. AI
IMPACT This research suggests current multimodal brain-encoding models may not effectively capture behavioral engagement signals, highlighting a gap in predicting user interaction with content.
