2024-04-09 11:06:13 PiSSA: Principal Singular Values and Singular Vectors Adaptation of Large Language Models

Significantly improved finetuned perf by simply changing the initialization of LoRA's AB matrix from Gaussian/zero to principal components.

On GSM8K, Mistral-7B fine-tuned with PiSSA achieves an accuracy of 72.86%, outperforming LoRA’s 67.7% by 5.16%.

2023-09-14 20:22:31 Introducing Würstchen: Fast Diffusion for Image Generation

Diffusion model, whose text-conditional component works in a highly compressed latent space of images

Würstchen - это диффузионная модель, которой работает в сильно сжатом латентном пространстве изображений.

Почему это важно? Сжатие данных позволяет на порядки снизить вычислительные затраты как на обучение, так и на вывод модели.

Обучение на 1024×1024 изображениях гораздо затратное, чем на 32×32. Обычно в других моделях используется сравнительно небольшое сжатие, в пределах 4x - 8x пространственного сжатия.

Благодаря новой архитектуре достигается 42-кратное пространственное сжатие!

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.

2023-06-05 07:53:43 ​​The effectiveness of MAE pre-pretraining for billion-scale pretraining

Revolutionizing the current pretrain-then-finetune paradigm of computer vision, this research has introduced an innovative pre-pretraining stage. Utilizing the Masked Autoencoder (MAE) technique for model initialization, this pre-pretraining strategy scales with the size of both the model and the data. This makes it an ideal tool for training next-generation foundation models, even on the grandest scales.

The robustness of our pre-pretraining technique is demonstrated by consistent improvement in model convergence and downstream transfer performance across diverse model scales and dataset sizes. The authors measured the effectiveness of pre-pretraining on a wide array of visual recognition tasks, and the results have been promising. The ielargest model achieved unprecedented results on iNaturalist-18 (91.3%), 1-shot ImageNet-1k (62.1%), and zero-shot transfer on Food-101 (96.0%), underlining the tremendous potential of proper model initialization, even when handling web-scale pretraining with billions of images.
