深度学习的可解释性研究综述

近年来,深度学习在很多领域得到广泛应用;然而,由于深度神经网络模型的高度非线性操作,导致其可解释性较差,并常常被称为“黑箱”模型,无法应用于一些对性能要求较高的关键领域;因此,对深度学习的可解释性开展研究是很有必要的。首先,简单介绍了深度学习;然后,围绕深度学习的可解释性,从隐层可视化、类激活映射（CAM）、敏感性分析、频率原理、鲁棒性扰动测试、信息论、可解释模块和优化方法这8个方面对现有研究工作进行分析;同时,展示了深度学习在网络安全、推荐系统、医疗和社交网络领域的应用;最后,讨论了深度学习可解释性研究存在的问题及未来的发展方向。

Microvascular Experimentation in the Chick Chorioallantoic Membrane as a Model for Screening Angiogenic Agents including from Gene-Modified Cells

The chick chorioallantoic membrane (CAM) assay model of angiogenesis has been highlighted as a relatively quick, low cost and effective model for the study of pro-angiogenic and anti-angiogenic factors. The chick CAM is a highly vascularised extraembryonic membrane which functions for gas exchange, nutrient exchange and waste removal for the growing chick embryo. It is beneficial as it can function as a treatment screening tool, which bridges the gap between cell based in vitro studies and in vivo animal experimentation. In this review, we explore the benefits and drawbacks of the CAM assay to study microcirculation, by the investigation of each distinct stage of the CAM assay procedure, including cultivation techniques, treatment applications and methods of determining an angiogenic response using this assay. We detail the angiogenic effect of treatments, including drugs, metabolites, genes and cells used in conjunction with the CAM assay, while also highlighting the testing of genetically modified cells. We also present a detailed exploration of the advantages and limitations of different CAM analysis techniques, including visual assessment, histological and molecular analysis along with vascular casting methods and live blood flow observations.

Decomposition and reconstitution principle for complex surfaces and its applications

Though there are already a variety of models for complex surfaces, they are not so convenient as needed in practice. A hierarchical model and the principle of decomposition and reconstitution for complex surfaces have been proposed, which have the potential to enhance the support of automated design systems on creative work intelligently Then the progress made is discussed involving the applications of the new principle in the following three areas:conjugation surface calculation, tool path generation in numerically controlled machining, and machining process innovation by re-recognition
