以旅游大数据为基础,考虑长时间范围内的滞后效应以及不同搜索强度指数(Search Intensity Index,SII)之间的多任务影响,提出一种基于大数据的多任务旅游信息分析(Multi-tasking Tourism Information Analysis Based on Big Data,MTIABD)框架。使用融合信息重排序技术预测旅游需求,具体根据图引导结构模拟历史变量对未来变量的滞后影响。每个变量通过时间维度上的卷积神经网络(Convolutional Neural Network,CNN)进行独立编码,利用二分图动态建模滞后效应,通过图聚合进行挖掘,实现对旅游需求的精准预测。基于上述技术,构建旅游需求预测系统,旅游者能够根据需求检索不同景点的信息。在真实数据集上进行大量实验,结果表明所提出的MTIABD框架在一步和多步预测方面均优于现有方法。在平均绝对百分比误差(Mean Absolute Percentage Error,MAPE)指标下,相较于基于实例的多变量时间序列图预测框架(Instance-wise Graph-rased Framework for Multivariate Time Series Forecasting,IGMTF),MTIABD在HK-2021数据集上的性能提高了16.75%,在MO-2021数据集上的性能提高了19.79%。
“显示技术与器件”是一门以物理、光学、电子电路为基础和面向产业的应用性学科。为了适应目前信息显示产业快速发展带来的人才需求,针对该课程目前存在的知识点相对独立和零散,理论知识庞杂以及应用性不突出的特点,教学团队采用项目式教学模式,通过调整知识单元、面向产业和就业的项目式教学方法等措施进行教学改革。采用传统课堂学习和项目任务完成评价有机的融合为一体,实践结果表明:通过项目式教学,学生的积极性、课程教学实效和学生能力收获得感均得到较好的反馈。“Display Technology and Devices” represents an applied discipline rooted in physics, optics, and electronic circuits, specifically tailored to meet industry demands. In response to the talent requirements arising from the rapid advancement of the information display sector, the instructional team has embraced a project-based teaching model to effectively address the current characteristics of the course. These characteristics include relatively autonomous and fragmented knowledge segments, intricate theoretical concepts, and a pronounced deficiency in tangible applicability. Initiatives such as the restructuring of knowledge units and the implementation of industry-oriented, project-based instructional methodologies have been introduced to facilitate teaching reforms. This approach fosters a cohesive integration of traditional classroom learning with the evaluation of project task completion. Empirical evidence indicates that project-based teaching has significantly enhanced student engagement, improved the efficacy of course instruction, and bolstered students’ sense of achievement, all receiving positive feedback.
