深度学习的发生机制与多模态数据测评研究

进入数字化知识经济时代,社会发展对教育活动提出了更高要求,旨在培养高阶思维和创新能力的深度学习备受国际社会的高度关注。为此,“深度学习如何发生”和“如何评估深度学习发生程度”,也成为亟待研究的两个关键学术问题。认知心理学、教育神经学和具身认知为理解深度学习提供了理论基础,指引人们从人—物互动视角认识个体的认知变化过程,打开了个体学习的内隐机制“黑箱”,实现内隐机制和外显表征的桥接与理解。基于这一认识与分析,通过信息输入、深度加工和学习生成三个环节,初步构建了深度学习的发生机制模型,并设置相关的学习状态指标。而要实现对深度学习发生程度的精准评价,则应依据深度学习的多模态数据测评框架,综合性采集与分析学习者的生理数据、自我评估数据、在线学习平台数据和课堂参与数据等多模态数据。但是,在采用多模态数据测评深度学习的发生及其程度时,多模态数据仍存在异质性差距、数据建模缺乏精确度、常态化评价开展困难、数据安全和伦理道德难以得到保障等问题,亟需未来开展更为深入的研究与探索。     

The Pedagogy and Pleasures of Teaching a 21st-Century Skill

Since at least the 1990s, voices both inside and outside the academy have vigorously debated whether the university has the responsibility to educate students in ‘transferable skills’ in addition to disciplinary content. Lists of these skills often include critical thinking, problem solving, collaboration, and innovation, and, almost always, communication, this article's focus. I briefly review the debate on whether such skills should be a prominent part of the university curriculum, and specifically address one argument advanced by the critics—that these skills cannot be taught. I describe my experience teaching communication relying on research-based practices and reflect on what it means to teach transferable skills in the digital age, as pedagogy changes and the university extends its reach. The article concludes with a recommendation to expand the teaching and learning of transferable skills and suggests how this can be accomplished.     

An in-plane low-noise accelerometer fabricated with an improved process flow

We present a bulk micromachined in-plane capacitive accelerometer fabricated with an improved process flow, by etching only one-fifth of the wafer thickness at the back of the silicon while forming the bar-structure electrode for the sensing capacitor. The improved flow greatly lowers the footing effect during deep reactive ion etching （DRIE）, and increases the proof mass by 54% compared to the traditional way, resulting in both improved device quality and a higher yield rate. Acceleration in the X direction is sensed capacitively by varying the overlapped area of a differential capacitor pair, which eliminates the nonlinear behavior by fixing the parallel-plate gap. The damping coefficient of the sensing motion is low due to the slide-film damping. A large proof mass is made using DRIE, which also ensures that dimensions of the spring beams in the Y and Z directions can be made large to lower cross axis coupling and increase the pull-in voltage. The theoretical Brownian noise floor is 0.47 μg/Hz^1/2 at room temperature and atmospheric pressure. The tested frequency response of a prototype complies with the low damping design scheme. Output data for input acceleration from -1 g to 1 g are recorded by a digital multimeter and show very good linearity. The tested random bias of the prototype is 130 μg at an averaging time of around 6 s.

面向计算机的深度语义分析

阐述了“深度语义分析”中“语义”的含义,强调了深度语义分析对计算机处理自然语言的必要性,接着以动词为例,具体举出了三种分析的方法,即：对词语的多个义项进行详细的语义描写;弄清动词的格框,抓住动核的必有论元,补出与自然语言理解有关的省略成分;弄清词语之间的强式语义组配模式。     

从“二人”关系看中国文化的深层结构——孙隆基《中国文化的深层结构》解读

文化具有表层和深层之分。通常情况下,人们看到的往往只是表象,而美籍华人孙隆基先生的著作《中国文化的深层结构》正是通过对“仁”——“二人关系”的解剖,挖掘出中国文化的深层结构是“二人”关系,即把个体价值消融于群体关系,从而也在一定程度上揭开了中国传统文化之谜。
