为解决颈椎健康评分及数据标注困难的问题,提出一种基于多值输入多示例学习的颈椎健康状态在线评分算法,仅需在训练阶段对颈椎运动数据长时序列的简单评分标注,即可估计颈椎短时状态的健康评分.首先将多值输入的多示例学习模型划分为多个二值输入的子分类器并分别进行训练,然后使用高斯模型将各个子分类器训练得到的示例分值融合,最后以一种新的包得分机制计算包的分值并完成颈椎健康状态的实时评分.通过包的分值预测准确率计算、示例可视化显示与分析、包得分曲线显示与分析和实时分值评分分析这些定性和定量实验,说明了该算法评估用户颈椎健康的有效性. 相似文献

在3G网络到来之前,GSM的无线数据业务将越来越多的被应用,EDGE无线分组业务将受到更多的要求和关注。考虑到3G的入网延迟和移动数据业务的大量需求,预计能带来高速数据传输的EDGE将在不久的将来在现网被大规模地推广和应用,终端用户也将能体验到更多的新业务类型,而QoS是这些高速数据业务的保证,它势必将作为一个重要的特性出现在EDGE网络中并让终端用户确实感觉到它的实用价值。目前,很多设备制造商在最新产品中已经引进了QoS的支持,[第一段] 相似文献

In this paper, we address the demanding task of developing intelligent systems equipped with machine creativity that can perform design tasks automatically. The main challenge is how to model human beings' creativity mathematically and mimic such creativity computationally. We propose a ``synthesis reasoning model" as the underlying mechanism to simulate human beings' creative thinking when they are handling design tasks. We present the theory of the synthesis reasoning model, and the detailed procedure of designing an intelligent system based on the model. We offer a case study of an intelligent Chinese calligraphy generation system which we have developed. Based on implementation experiences of the calligraphy generation system as well as a few other systems for solving real-world problems, we suggest a generic methodology for constructing intelligent systems using the synthesis reasoning model. 相似文献
