Determinants of range effects in face recognition     

Verbeek EL  Spetch ML  Cheng K  Clifford CW 《Learning & behavior》2006,34(3):229-240

The effects of test stimulus range on generalization gradients in humans were assessed for discriminations between faces that varied in brightness, faces that varied in orientation in the picture plane, and morphed faces. In Experiment 1, significant range effects, predicted by adaptation level theory, occurred when faces varied along the brightness or orientation dimension, but not for morphed faces. Changing the difficulty of discrimination of both training and test stimuli for Experiment 2 produced range effects in morphed faces. Experiment 3 explored training and testing stimulus factors as determinants of range effects in morphed faces. The results suggest that sufficiently biased testing ranges create shifts in response distributions (generalization gradients), and this may be amplified by using relatively difficult discriminations between training stimuli.  相似文献

AI新时代面向文化遗产活化利用的智慧数据生成路径探析     

范炜  曾蕾 《中国图书馆学报》2024,50(2):4-29

生成式人工智能引爆AI新时代,新技术不断涌现并快速迭代更新,AI技术应用呈现出百花齐放、百家争鸣的繁荣发展局面。借助AI发展东风,智慧数据的生成进入了高效、深化、多模态集成的新阶段,提升了数据驱动的文化遗产活化利用创新手段和创新形式的丰富度与可行性。本文旨在探索面向文化遗产活化利用的智慧数据生成路径。首先,从AI技术视角,对文化遗产智慧数据的内涵与价值进行回顾并知新;其次,系统分析从多元异构数据资源中生成智慧数据的典型做法;再次,以羌年为例,探讨非遗活态文化的智慧数据生成思路。最后,总结归纳AI赋能文化遗产智慧数据生成路径的四点参考策略：(1)抓住AI赋能机遇,补齐数据基础设施短板,加强数据资源体系建设;(2)尽快开展馆藏数据资源的“大语言模型+知识库”结合工作,实现智能分析与计算增强;(3)鼓励更广泛的文化遗产数据开放与共享,支持活化利用的创新应用;(4)确保可信的智慧数据。图3。表1。参考文献68。  相似文献   

Gaining and Sustaining TEL in a 1:1 Laptop Initiative: Possibilities and Challenges for Teachers and Students     

Marcia J. P. Håkansson Lindqvist 《学校用计算机》2015,32(1):35-62

The uptake and use of digital technologies is studied in Unos Umeå, a joint one-to-one (1:1) research project between Umeå University and the municipality of Umeå in Sweden. This article presents the results of the third phase of the classroom work with laptops. Using the ecology of resources model (Luckin, 2010), these possibilities and challenges can be interpreted as the manifestation of filters in the learning environment. Alleviating technical problems, targeting low student laptop use, teacher collaboration, and teacher professional development (TPD) may help teachers and students gain and sustain technology-enhanced learning (TEL) in this 1:1 initiative.  相似文献   

Compliance with freedom of information legislation by public bodies in South Africa     

Marcia Nkwe  Mpho Ngoepe 《Government Information Quarterly》2021,38(2):101567

In South Africa, freedom of information (FOI) is entrenched in section 32 of the Constitution, which guarantees every citizen the right of access to any information held by the state or by any other person that is to be used for the protection or exercise of any right. The Promotion of Access to Information Act (PAIA) is the law that gives effect to section 32 of the Constitution. Regardless of a remarkable trend towards the adoption of FOI laws, international trends have shown this does not automatically translate into fulfilment of people's right to information. This study utilised mixed method research through the explanatory sequential design to assess compliance with FOI legislation by public bodies in South Africa, with a view to develop a model for implementation of FOI. The study first conducted a quantitative study by analysing the reports of the South African Human Rights Commission from the reporting years 2006/07 to 2016/07 to assess compliance with sections 14, 15, 16, 17 and 32 of the PAIA. Thereafter, a qualitative study through interviews with purposively chosen participants was conducted to substantiate the findings of a quantitative study. Key results suggest that over the years, there were problems in the implementation of the FOI legislation in South Africa and its use was limited. Where implementation has taken place, it has been partial and inconsistent. The responsibility for the implementation of FOI legislation in most public bodies is assigned to legal departments that do not have knowledge of what records are created, and where and how they are kept. With regard to compliance, in terms of the degree of comparison, the situation was better in national departments, worse in provincial departments and worst in municipalities. The study recommends the establishment of an information governance unit to implement FOI in public bodies. Failure to assign responsibility to a relevant unit would perpetuate the non-compliance with FOI legislation by public bodies in South Africa. A model for the implementation of PAIA within a public body is suggested.  相似文献
