内容摘要：

  在这个大数据/人工智能/机器学习时代，当我们用约1750亿个自由参数训练网络时，降维有多重要？即使如今所有问题都不是大数据问题，不涉及文字和（或）图像，或很多问题不能依赖于黑盒模型，降维仍具有相关性和重要性。此外，通常这些黑盒系统无法应对现实生活中决策系统的开放世界性质。因此，降维、数据可视化、决策系统的透明度及其应对开放世界问题的能力非常重要。下面将讨论模糊系统对于这些问题的方法设计：降维保持数据的几何结构；一种独特的综合特征选择和系统识别的方法；当高维数据基本上位于低维流形上时的一种流形学习方法，其中一些方法是首次尝试。接下来将阐述这样的模糊系统如何能够轻松地避免在它应该做出决定的时候做出决定。最后，将讨论一些需要进一步研究的问题。

Abstract:

      How relevant is dimensionality reduction in this era of big data/AI/ML when we train networks with about 175 billion free parameters? In my view, it is still relevant and important because even today all problems are not big data problems; all problems do not involve texts and/or images;  and many problems cannot rely on black-box models. Moreover, usually these black-box systems cannot deal with the open-world nature of real-life decision making systems. Consequently, dimensionality reduction, data visualization, transparency of  a decision making system, and its ability to cope with the open-world problems are important. We shall discuss these issues and explain how fuzzy systems can realize the desirable attributes of a decision making system. Next I shall discuss  designing of fuzzy systems for these tasks: dimensionality reduction preserving the geometric structure of the data; an unique integrated approach to feature selection and system identification; and manifold learning when a high dimensional data lie essentially on a lower dimensional manifold. Some of these are first attempts. I shall demonstrate how easily such a system can refrain from making a decision when it should. Finally, I shall discuss some of the problems that need further investigation.
