ViBT Image Generation: How Brownian Bridge Models Achieve 4× Faster AI Inference
20 days ago 高效码农ViBT: Vision Bridge Transformer at Scale – A Practical Deep Dive What is ViBT and why does it achieve up to 4× faster inference than token-heavy conditional diffusion models while maintaining comparable quality? ViBT is the first large-scale realization of Brownian Bridge generative models for vision tasks. Instead of the classic “noise-to-data” paradigm, it directly learns stochastic trajectories from a structured source (image/video) to a structured target, eliminating most conditioning tokens and dramatically reducing compute. Figure: Example results of ViBT across instruction-based editing, stylization, colorization, and frame interpolation. Why the Noise-to-Data Paradigm Feels Wrong for Conditional Generation Most modern image …

From Human Memory to AI Continual Learning: How Nested Learning Solves the “Amnesia” Problem in Large Models
1 months ago 高效码农If you’ve been following machine learning’s evolution, you’ve probably noticed a strange paradox: while today’s AI systems can write poetry, debug code, and reason through complex problems, they still struggle with something a three-year-old does effortlessly—learning new things without forgetting old ones. It’s like meeting someone who can recite the entire encyclopedia but can’t remember your name five minutes after you meet. Google Research’s recent introduction of Nested Learning, presented at NeurIPS 2025, challenges this fundamental limitation. This isn’t another incremental architecture tweak. It’s a rethinking of how we understand deep learning itself, inspired by how the human brain continually …
From O(n²) to O(L·√L): How DeepSeek-V3.2-Exp Slashes Long-Context Costs Without Hurting Quality
2 months ago 高效码农A 5-minute read for engineers who need 128 K tokens tonight, not next quarter. 1. The Scene: 2 A.M. and the Context-Length Wall Li, a Beijing-based ML engineer, just wanted his 671 B model to read a 100 k-token spec and answer one obscure question. By token 60 k the GPU fans sounded like jet engines; at 90 k the server threw an OOM and the latency graph looked like Everest. Sound familiar? Long-context is the new memory wall—and the bill is paid in both dollars and sleep. The next morning DeepSeek dropped an experimental image on Docker Hub: lmsysorg/sglang:dsv32 …
AI Video Restoration: Transform Blurry Videos to Cinematic Clarity with Text-to-Video AI
4 months ago 高效码农Vivid-VR: Turning Blurry Footage into Cinematic Clarity with a Text-to-Video Transformer Authors: Haoran Bai, Xiaoxu Chen, Canqian Yang, Zongyao He, Sibin Deng, Ying Chen (Alibaba – Taobao & Tmall Group) Paper: arXiv:2508.14483 Project page: https://csbhr.github.io/projects/vivid-vr/ 1. Why Should You Care About Video Restoration? If you have ever tried to upscale an old family video, salvage a live-stream recording, or polish AI-generated clips, you have probably asked: “ “Photos can be enhanced—why not videos?” Traditional tools either leave the footage smeared or create disturbing “AI faces.” Pure diffusion image models fix one frame beautifully but give the next frame a new …
