视觉异常检测(VAD)是机器学习中的关键领域,旨在识别图像中偏离正常模式的异常,常面临异常数据稀缺和无监督训练需求的挑战。为加速该领域的研究与实际部署,我们提出MoViAD——一个全面且高度模块化的库,提供对当前最优VAD模型、训练器、数据集及实用工具的快速访问。该库支持持续学习、半监督、少样本、噪声数据等多种场景,并通过专门的边缘与物联网(Edge and IoT)设置解决实际部署难题,提供优化后的模型与骨干网络,以及量化与压缩工具,实现高效的本地执行与分布式推理。MoViAD集成多种骨干网络、鲁棒的评估指标(像素级与图像级)及效率分析工具。其设计兼顾快速部署与高度可扩展性,使工程师可轻松适配自定义模型、数据集与骨干网络,同时为研究人员提供灵活实验环境以开发新方法。

原文摘要 · Abstract (English)

VAD is a critical field in machine learning focused on identifying deviations from normal patterns in images, often challenged by the scarcity of anomalous data and the need for unsupervised training. To accelerate research and deployment in this domain, we introduce MoViAD, a comprehensive and highly modular library designed to provide fast and easy access to state-of-the-art VAD models, trainers, datasets, and VAD utilities. MoViAD supports a wide array of scenarios, including continual, semi-supervised, few-shots, noisy, and many more. In addition, it addresses practical deployment challenges through dedicated Edge and IoT settings, offering optimized models and backbones, along with quantization and compression utilities for efficient on-device execution and distributed inference. MoViAD integrates a selection of backbones, robust evaluation VAD metrics (pixel-level and image-level) and useful profiling tools for efficiency analysis. The library is designed for fast, effortless deployment, enabling machine learning engineers to easily use it for their specific setup with custom models, datasets, and backbones. At the same time, it offers the flexibility and extensibility researchers need to develop and experiment with new methods.
