​​Tracking Everything Everywhere All at Once

In the field of motion estimation, a remarkable breakthrough has just arrived! Introducing OmniMotion, an innovative method that pioneers a complete and globally consistent motion representation. OmniMotion moves beyond the constraints of traditional optical flow or particle video tracking algorithms that are hindered by limited temporal windows and difficulties in maintaining global consistency of estimated motion trajectories. Instead, OmniMotion enables accurate, full-length motion estimation of every pixel in a video sequence - a truly remarkable feat.

OmniMotion represents a video using a quasi-3D canonical volume and accomplishes pixel-wise tracking via the transformation between local and canonical spaces. This representation doesn't just ensure global consistency; it also opens the doors to tracking through occlusions and modeling any mixture of camera and object motion. The extensive evaluations conducted on the TAP-Vid benchmark and real-world footage have proven that OmniMotion outperforms existing state-of-the-art methods by a substantial margin, both quantitatively and qualitatively.

​​QLoRA: Efficient Finetuning of Quantized LLMs

Thia paper introduces QLoRA, a novel finetuning approach that decreases memory usage significantly, while maintaining impressive performance. Imagine this - a 65 billion parameter model finetuned on a single 48GB GPU, while preserving full 16-bit task performance. This method involves backpropagating gradients through a frozen, 4-bit quantized pretrained language model into Low Rank Adapters, a method that opens up new frontiers in machine learning. The icing on the cake is their high-performing model family, Guanaco, which trumps all previously released models on the Vicuna benchmark, achieving a staggering 99.3% of the performance level of ChatGPT with just 24 hours of finetuning on a single GPU.

The study also unveils several innovative techniques to conserve memory without compromising performance. These include 4-bit NormalFloat (NF4), an innovative data type that is theoretically optimal for normally distributed weights, double quantization for average memory footprint reduction, and paged optimizers to handle memory spikes. The QLoRA approach was applied to finetune more than 1000 models, leading to a detailed analysis of instruction following and chatbot performance across various model types and scales. The results affirm that QLoRA finetuning on a small, high-quality dataset yields state-of-the-art results, even with smaller models than previously used. A notable finding is that GPT-4 evaluations offer a cost-effective alternative to human evaluation. All models and code, including CUDA kernels for 4-bit training, have been released by the researchers.

​​Voicebox: Text-Guided Multilingual Universal Speech Generation at Scale

In the ever-evolving field of natural language processing and computer vision research, the revolution is being led by large-scale generative models like GPT and DALL-E. These models have the remarkable capability of generating high fidelity text or image outputs, and more importantly, they possess a 'generalist' character, able to solve tasks that they weren't explicitly trained to accomplish. However, when it comes to speech generative models, there's still a significant gap in terms of scale and task generalization. Enter, Voicebox - a pioneering advancement set to redefine the landscape of speech generation technology.

Voicebox is an exceptionally versatile text-guided generative model for speech at an impressive scale. Trained on over 50K hours of unfiltered, unenhanced speech data, Voicebox is a non-autoregressive flow-matching model, designed to infill speech, given an audio context and text. Much like its predecessors, Voicebox is able to perform a wide range of tasks through in-context learning, but with an added flexibility - it can condition on future context. The applications are boundless - from mono or cross-lingual zero-shot text-to-speech synthesis to noise removal, content editing, style conversion, and diverse sample generation. What's truly phenomenal is Voicebox's capability to outshine the state-of-the-art zero-shot TTS model, VALL-E, on both intelligibility and audio similarity metrics, while being a staggering 20 times faster.

​​Self-Supervised Learning from Images with a Joint-Embedding Predictive Architecture

In a recent breakthrough, a novel approach for learning highly semantic image representations has been introduced that eschews the need for hand-crafted data augmentations. The strategy, known as Image-based Joint-Embedding Predictive Architecture (I-JEPA), offers a refreshing, non-generative pathway to self-supervised learning from images. The concept underpinning I-JEPA is deceptively simple, yet incredibly powerful: it takes a single context block from an image and predicts the representations of various target blocks within the same image.

I-JEPA's core design principle - its masking strategy - plays a pivotal role in shaping the system's semantic prowess. The key is to sample target blocks at a sufficiently large, semantic scale while using a context block that provides ample, spatially distributed information. When integrated with Vision Transformers, I-JEPA exhibits impressive scalability. To illustrate, a ViT-Huge/14 model was trained on ImageNet using just 16 A100 GPUs in under 72 hours, delivering robust performance across a wide spectrum of tasks, including linear classification, object counting, and depth prediction.

​​StableRep: Synthetic Images from Text-to-Image Models Make Strong Visual Representation Learners

In a ground-breaking exploration of visual representation learning, researchers have leveraged synthetic images produced by leading text-to-image models, specifically Stable Diffusion, achieving promising results. The study uncovers two key insights - firstly, when configured correctly, self-supervised methods trained on synthetic images can match or even outperform those trained on real images. This suggests an exciting avenue for efficient and effective representation learning, reducing the need for extensive real image datasets.

Secondly, the researchers have devised a novel approach called StableRep, a multi-positive contrastive learning method that treats multiple images, generated from the same text prompt, as mutual positives. The compelling finding is that StableRep, trained solely with synthetic images, outperforms representations learned by prominent methods such as SimCLR and CLIP, even when these used real images. In a striking demonstration, when language supervision is added, StableRep trained with 20M synthetic images outperforms CLIP trained with a whopping 50M real images. These findings not only underscore the potential of synthetic data but also pave the way for more efficient, large-scale visual representation learning.

​​Scaling Transformer to 1M tokens and beyond with RMT

Imagine extending the context length of BERT, one of the most effective Transformer-based models in natural language processing, to an unprecedented two million tokens! This technical report unveils the Recurrent Memory Transformer (RMT) architecture, which achieves this incredible feat while maintaining high memory retrieval accuracy.

The RMT approach enables storage and processing of both local and global information, allowing information flow between segments of the input sequence through recurrence. The experiments showcase the effectiveness of this groundbreaking method, with immense potential to enhance long-term dependency handling in natural language understanding and generation tasks, as well as enable large-scale context processing for memory-intensive applications.
