Lights and shadows in Evolutionary Deep Learning: Taxonomy,critical methodological analysis,cases of study,learned lessons,recommendations and challenges

Much has been said about the fusion of bio-inspired optimization algorithms and Deep Learning models for several purposes: from the discovery of network topologies and hyperparametric configurations with improved performance for a given task, to the optimization of the model’s parameters as a replacement for gradient-based solvers. Indeed, the literature is rich in proposals showcasing the application of assorted nature-inspired approaches for these tasks. In this work we comprehensively review and critically examine contributions made so far based on three axes, each addressing a fundamental question in this research avenue: (a) optimization and taxonomy (Why?), including a historical perspective, definitions of optimization problems in Deep Learning, and a taxonomy associated with an in-depth analysis of the literature, (b) critical methodological analysis (How?), which together with two case studies, allows us to address learned lessons and recommendations for good practices following the analysis of the literature, and (c) challenges and new directions of research (What can be done, and what for?). In summary, three axes – optimization and taxonomy, critical analysis, and challenges – which outline a complete vision of a merger of two technologies drawing up an exciting future for this area of fusion research.     

A review of digital twin in product design and development

In the era of digitalization, there are many emerging technologies, such as the Internet of Things (IoT), Digital Twin (DT), Cloud Computing and Artificial Intelligence (AI), which are quickly developped and used in product design and development. Among those technologies, DT is one promising technology which has been widely used in different industries, especially manufacturing, to monitor the performance, optimize the progresses, simulate the results and predict the potential errors. DT also plays various roles within the whole product lifecycle from design, manufacturing, delivery, use and end-of-life. With the growing demands of individualized products and implementation of Industry 4.0, DT can provide an effective solution for future product design, development and innovation. This paper aims to figure out the current states of DT research focusing on product design and development through summarizing typical industrial cases. Challenges and potential applications of DT in product design and development are also discussed to inspire future studies.     

新时期空间规划转向与政策绩效提升路径

公共政策限制或扩展了人的行为, 以此牵引空间需求并塑造城乡形态。而城乡 规划的本质即是人类社会对空间需求的集体 意志,是权衡社会、文化、经济和环境等无 边界因素之后的集体选择。城乡规划在新时 期融入了国土空间规划体系,但由于边界不 明确、作用机制不明朗、效果不直接、责任难 认定等原因,在积极贡献的同时,承受了较多 质疑甚至不实之责。为了更加清晰地认知空 间规划及其政策,可以借鉴西方城市发展和 规划理论探索经验,重新认知和区分规划领 域学理、法理、机理的内涵与差别,同时,探 讨提升空间规划政策绩效的路径,大体包括 推动经验判断转向情景演算、识别实施传导 机制、划定可试错的领域并完善纠错机制以 及促进规划政策全过程的知识积累等方面。
