人工智能之拟人化

喻丰; 许丽颖
Subjects: Psychology >> Social Psychology

人工智能及其载体或者存在形式(如智能机器人、自动驾驶汽车等)不只具有智能,更具有社会功能。社会功能之具备得益于人工智能的拟人化。拟人化是将人类特征、动机、意向或心理状态赋予非人对象的心理过程或者个体差异,拟人化的产生受到激发主体知识、效能动机和社会动机的影响。对人工智能的拟人化影响存在如何拟人化(即拟人化的人工智能知觉以及破除恐怖谷效应等问题)、何时拟人化(即何种人格者在何种情境下更易拟人化人工智能)、拟人化何用(即拟人化人工智能的好处和意义)以及拟人化后的社会互动行为等问题。本文在心理学和人—机器人交互研究的基础上,讨论人工智能拟人化的如何、何时及为何问题,并对人工智能设计提供心理学思考。

如何做一个道德的人工智能体?心理学的视角

喻丰; 许丽颖
Subjects: Psychology >> Social Psychology

人工智能的飞速发展产生了一系列道德困境,如何做出道德的人工智能体(如道德人工智能机器人)成为了必须回答的问题。本文从心理学视角探究了人工智能体是否可能被赋予道德地位、被如何赋予何种道德地位;人工智能体是否需要及需要何种道德能力;人工智能体如何获得及获得何种道德规则;人工智能体能够如何深化人类对于人性、关系以及多样化的道德理解等多种问题进行了回答。从心理学的理论和实证研究出发,切实回答如何做出道德的人工智能体的疑问,期望对以人为中心的人工智能研究提供道德心理学智慧。

生物转化低值生物质制备生物油脂

Subjects: Biology >> Bioengineering

The current crisis of global warming is primarily attributed to CO2 production from excessive use of fossil fuels during recent decades, and has increased demand for renewable biofuels tremendously. Lipids are drawing considerable attention in relation to the production potential of biodiesel on the basis of their nontoxic, sustainable, and energy efficient proprieties. However, the high cost of microbial lipid produced by oleaginous microorganisms mainly stems from the high cost of glucose, which is estimated to be about 80% of the total medium cost. Therefore, considerable efforts have been directed toward minimizing the carbon source cost and finding new alternative carbon sources. In this report, several low-cost biomass including food-waste-derived volatile fatty acids, lignocellulose-based sugars, and methane derived from biogas were investigated for lipid production. After developing the culture modes and optimizing the culture conditions, both high lipid titer and productivity were achieved in high cell density cultures of different microorganisms using various carbon sources.
