Vision Transformer

This repository provides the official implementation of Vision Transformer (ViT) and MLP-Mixer architectures for image recognition, based on seminal research papers from Google Research. It includes pre-trained models on datasets like ImageNet and ImageNet-21k, along with code for fine-tuning on custom datasets using JAX and Flax. ## Key Features - **Vision Transformer (ViT)** — Applies transformer architecture to image patches for scalable image recognition. - **MLP-Mixer** — An all-MLP architecture for vision tasks, offering an alternative to convolutional networks. - **Pre-trained Models** — Includes a wide variety of ViT and Mixer models (e.g., ViT-B/16, ViT-L/16, Mixer-B/16) pre-trained on ImageNet and ImageNet-21k. - **Fine-tuning Support** — Provides configurable scripts to fine-tune models on datasets like CIFAR-10, CIFAR-100, and custom datasets. - **LiT Models** — Includes Locked-image text Tuning models for zero-shot transfer learning with image-text alignment. - **Cloud Integration** — Supports training on Google Cloud VMs with GPU or TPU accelerators. ## Philosophy The project emphasizes reproducibility and accessibility of state-of-the-art vision models, offering well-documented code and pre-trained checkpoints to facilitate research and practical applications in computer vision.

mip-NeRF

Mip-NeRF is an extension of Neural Radiance Fields (NeRF) that addresses aliasing artifacts by representing scenes at continuously-valued scales. It renders anti-aliased conical frustums instead of single rays, enabling higher-quality synthesis of novel views from 2D images while being faster and more compact than the original NeRF. ## Key Features - **Multiscale Scene Representation** — Models scenes at continuous scales to handle varying image resolutions. - **Anti-Aliased Rendering** — Renders conical frustums instead of rays, reducing blur and aliasing artifacts. - **Improved Detail Preservation** — Significantly enhances NeRF's ability to capture fine details. - **Computational Efficiency** — 7% faster than NeRF and half the model size, while reducing error rates by 17-60%. - **Scalable Performance** — Matches brute-force supersampled NeRF accuracy while being 22x faster on multiscale datasets. ## Philosophy Mip-NeRF is designed to efficiently solve the aliasing problem in neural rendering by integrating multiscale representation directly into the NeRF framework, prioritizing both rendering quality and computational performance.
