To learn the underlying parent-child influence relationships between nodes in a diffusion network, most existing approaches require timestamps that pinpoint exact time when node infections occur historical processes. In many real-world processes like spread of epidemics, monitoring such infection temporal information is often expensive and difficult. this work, we study how to carry out network inference without timestamps, using only final statuses each process, which are more readily...

Heavy broilers exposed to hot summer conditions experience fluctuations in surface temperatures due heat stress, which leads decreased performance. Maintaining a bird's homeostasis depends on several environmental factors (temperature, relative humidity, and air velocity). It is important understand the responses of birds amount loss surrounding environment create thermal comfort for heavy improved performances welfare. This study investigates variation under high low velocity treatments....

Shared bicycles provide a green, environmentally friendly, and healthy mode of transportation that effectively addresses the “final mile” problem in urban travel. However, uneven distribution imbalance user demand can significantly impact experience bicycle usage efficiency, which makes it necessary to predict demand. In this paper, we propose novel shared-bicycle prediction method based on station clustering. First, address challenge capturing patterns station-level demand, exhibits...

Previous studies normally formulate named entity recognition (NER) as a sequence labeling task and optimize the solution in sentence level. In this article, we propose document-level optimization approach to NER apply it domain-specific task. As baseline, state-of-the-art approach, i.e., long-short-term memory (LSTM), perform word classification. On basis, define global objective function with obtained classification results achieve via Integer Linear Programming (ILP). Specifically,...

To identify the data examples of rare categories that form small compact clusters in large sets, existing approaches mostly require enough labeled as a training set to learn classifier, assuming rare-category are spherical or nearly spherical. Nonetheless, is usually difficult obtain practice, and many real-world applications often with arbitrary shapes. In this paper, we investigate how all category an shape based on only one seed (i.e., example). Instead finding local region around seed,...
