Overview
- LeanVAE is an ultra-efficient VAE designed for video diffusion models
- Uses wavelet transform and dual-pathway architecture for better compression
- Achieves 35.7× compression while maintaining high fidelity
- Runs 2.62× faster than previous methods like VQVAE
- Obtains state-of-the-art FVD scores when used in video generation
Plain English Explanation
Video diffusion models have revolutionized AI-generated videos, but they require massive computational resources. The bottleneck often lies in the encoding and decoding process handled by Variational Autoencoders (VAEs).
LeanVAE tackles this problem head-on. Think of it like a...
