PASSL is a Paddle based vision library for state-of-the-art Self-Supervised Learning research withPaddlePaddle. PASSL aims to accelerate research cycle in self-supervised learning: from designing a new self-supervised task to evaluating the learned representations.

Key features of PASSL：

• Reproducible implementation of SOTA in Self-Supervision

  Existing SOTA in Self-Supervision are implemented -SimCLR,MoCo(v1),MoCo(v2),MoCo-BYOL,BYOL,BEiT. Supervised classification training is also supported.

• Modular Design

  Easy to build new tasks and reuse the existing components from other tasks (Trainer, models and heads, data transforms, etc.)

🛠️ The ultimate goal of PASSL is to use self-supervised learning to provide more appropriate pre-training weights for downstream tasks while significantly reducing the cost of data annotation.

📣 Recent Update:

• (2022-2-9): Refactoring README
• 🔥 Now：

• Self-Supervised Learning Models

PASSL implements a series of self-supervised learning algorithms, SeeDocument for details on its use

Benchmark Linear Image Classification on ImageNet-1K.

Comming Soon：More algorithm implementations are already in our plans ...

• Classification Models

PASSL implements influential image classification algorithms such as Visual Transformer, and provides corresponding pre-training weights. Designed to support the construction and research of self-supervised, multimodal, large-model algorithms. SeeClassification_Models_Guide.md for more usage details

🔥 PASSL provides a detailed dissection of the algorithm, seeTutorial for details.

SeeINSTALL.md.

Please seeGETTING_STARTED.md for the basic usage of PASSL.
