《搜索和推荐中的深度匹配》——2.5 延伸阅读

Query重构是解决搜索中查询文档不匹配的另一种方法,即将Query转换为另一个可以进行更好匹配的Query。Query转换包括Query的拼写错误更正。例如,【1】提出了一种源渠道模型,【2】 提出了一种用于该任务的判别方法。Query转换还包括Query分段【3】【4】【5】。受统计机器翻译 (SMT) 的启发,研究人员还考虑利用翻译技术来处理Query文档不匹配问题,假设Query使用一种语言而文档使用另一种语言。【6】利用基于单词的翻译模型来执行任务。【7】 提出使用基于短语的翻译模型来捕获查询中单词和文档标题之间的依赖关系。主题模型也可用于解决不匹配问题。一种简单而有效的方法是使用term匹配分数和主题匹配分数的线性组合【8】。概率主题模型也用于平滑文档语言模型(或Query语言模型)【9】【10】。 【11】对搜索中语义匹配的传统机器学习方法进行了全面调查。

    Google Earth Engine ——MCD43C3第6版双向反射分布函数和反照率(BRDF/Albedo)反照率数据集是在0.05度(赤道5,600米)的气候模拟网格(CMG)中使用16天数据

    The MCD43C3 Version 6 Bidirectional Reflectance Distribution Function and Albedo (BRDF/Albedo) Albedo dataset is produced daily using 16 days of Terra and Aqua MODIS data in a 0.05 degree (5,600 meters at the equator) Climate Modeling Grid (CMG). Data are temporally weighted to the ninth day of the retrieval period which is reflected in the Julian date in the file name. This CMG product covers the entire globe for use in climate simulation models. MCD43C3 provides black-sky albedo (directional hemispherical reflectance) and white-sky albedo (bihemispherical reflectance) at local solar noon. Black-sky albedo and white-sky albedo values are available as a separate layer for MODIS spectral bands 1 through 7 as well as the visible, near infrared (NIR), and shortwave bands. Along with the 20 albedo layers are ancillary layers for quality, local solar noon, percent finer resolution inputs, snow cover, and uncertainty. See dataset user guide for more information.

    征稿|CEC 2023 Special Session on "EC in Healthcare Industry"

    Worldwide, the healthcare industry would continue to thrive and grow, due to the increasing demands of diagnosis, treatment, disease prevention, medicine, and service which affect the mortal rates and life quality of human beings. Two key issues of the modern healthcare industry are improving healthcare quality, as well as reducing economic and human costs. The problems in the healthcare industry can be formulated as scheduling, planning, predicting, and optimization problems, where evolutionary computation methods can play an important role. Although evolutionary computation has been applied to scheduling and planning for trauma system and pharmaceutical manufacturing, other problems in the healthcare industry such as decision making in computer-aided diagnosis and predicting for disease prevention have not been properly formulated for evolutionary computation techniques, and many evolutionary computation techniques are widely adopted in the healthcare community.
