鲁棒模式识别研究进展

Towards Robust Pattern Recognition: A Review

Xu-Yao Zhang, Cheng-Lin Liu, Ching Y. Suen

摘要:

许多模式识别任务的准确性逐年快速提高,达到甚至超过了人类的表现。从准确性的角度来看,模式识别似乎是一个即将解决的问题。然而,高精度的模式识别系统一旦投入实际应用,由于在开放和变化的环境中缺乏鲁棒性,可能会变得不稳定和不可靠。本文从打破封闭世界假设、独立同分布假设和干净大数据假设这三个基本假设的角度,对鲁棒模式识别的研究进行了综述,这些假设构成了大多数模式识别模型的基础。事实上,我们的大脑在复杂、开放和不断变化的环境中,在不同的背景、模式和任务下,通过在微弱或嘈杂的监督下只展示几个例子,不断地、渐进地学习概念。这些是人类智能和机器智能之间的主要区别,与上述三个假设密切相关。在见证了当今准确性提高的重大进展后,本文将使我们能够分析当前方法的缺点和局限性,并确定鲁棒模式识别的未来研究方向。

英文摘要:

The accuracies for many pattern recognition tasks have increased rapidly year by year, achieving or even outperforming human performance. From the perspective of accuracy, pattern recognition seems to be a nearly-solved problem. However, once launched in real applications, the high-accuracy pattern recognition systems may become unstable and unreliable, due to the lack of robustness in open and changing environments. In this paper, we present a comprehensive review of research towards robust pattern recognition from the perspective of breaking three basic and implicit assumptions: closed-world assumption, independent and identically distributed assumption, and clean and big data assumption, which form the foundation of most pattern recognition models. Actually, our brain is robust at learning concepts continually and incrementally, in complex, open and changing environments, with different contexts, modalities and tasks, by showing only a few examples, under weak or noisy supervision. These are the major differences between human intelligence and machine intelligence, which are closely related to the above three assumptions. After witnessing the significant progress in accuracy improvement nowadays, this review paper will enable us to analyze the shortcomings and limitations of current methods and identify future research directions for robust pattern recognition.
