Focal Transformer: Focal Self-attention for Local-Global Interactions in Vision Transformers
❤️ Become The AI Epiphany Patreon ❤️ ► https://www.patreon.com/theaiepiphany In this video I cover a new paper coming from Microsoft: "Focal Self-attention for Local-Global Interactions in Vision Transformers" where they introduce a new transformer layer called focal attention. The main idea is to reduce the complexity but preserve the long-range dependencies. They achieve this by attending to the nearby tokens in a fine-grained manner and to the tokens that are further away they attend their coarsened representations. ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ ✅ Paper: https://arxiv.org/abs/2107.00641 ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ ⌚️ Timetable: 00:00 Main idea of the paper: focal self-attention 04:55 Overview of Focal Transformer architecture 08:15 Focal Self-Attention layer 12:30 Computational complexity, overlapping regions 15:30 SOTA results but with a disclaimer 17:30 Ablations 19:50 Outro, Focal Transformer is slower than Swin ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ 💰 BECOME A PATREON OF THE AI EPIPHANY ❤️ If these videos, GitHub projects, and blogs help you, consider helping me out by supporting me on Patreon!
