💡 Idea

• Proposed Social Recovery After Holiday.
• Concept: Encourage post-holiday emotional reset and community motivation through shared recovery activities.
• Goal: Design small, collective habits that ease transition back to daily life after long holidays.

📖 Paper Study – InternVideo2 (CVPR 2024)

• Reviewed InternVideo2: Scaling Video Foundation Models for Multimodal Understanding.
• Key insights:
  • Introduces a unified framework combining masked video modeling, contrastive learning, and next-token prediction.
  • Focuses on spatiotemporal coherence and cross-modal (video–text–audio–speech) alignment.
  • Trained on 400M video-text pairs, achieving SOTA in video retrieval, captioning, and action recognition.
• Takeaway: InternVideo2 demonstrates how scalable multimodal architectures can generalize across diverse video-language tasks.
