Anchor-Guided Balanced Learning for Trajectory Representation
Trajectory Representations Learning (TRL) serves as a foundational technology for supporting intelligent transportation. However, models trained on real-world data often suffer from performance degradation caused by inherent spatiotemporal distribution bias, which reflects the heterogeneity of urban structures and human movement behaviors. This leads to representations that overfit to frequent patterns, resulting in weak robustness and limited ge…
Text Geolocation Prediction via Self-Supervised Learning
Text geolocation prediction aims to infer the geographic location of text with text semantics, serving as a fundamental task for various geographic applications. As the mainstream approach, the deep learning-based methods follow the supervised learning paradigms, which rely heavily on a large amount of labeled samples to train model parameters. To address this limitation, this paper presents a method for text geolocation prediction without labele…
The Promotion Effect of the Belt and Road Initiative on China's Tea Export Trade
Since the Belt and Road Initiative was put forward, countries that have signed cooperation agreements with China have become important partners of China's export trade. As a significant commodity in China's foreign trade, tea has ushered in a new development opportunity. This paper selects the data from the UN Comtrade database on China's tea export trade to 20 countries from 2008 to 2020 and uses the difference-in-differences model to study the …
Price Decision-Making in Dual-Channel Healthcare Services Supply Chain Considering the Channel Acceptance, Price Ceiling, and Public Welfare
Given that an increasing number of online healthcare channels play an essential role as a supply method in the healthcare service supply chain (HSSC), this paper studies the price decision-making problem for a dual-channel HSSC considering the channel acceptance, price ceiling, and public welfare. In this HSSC, a healthcare institution establishes both a traditional offline channel and an online channel to provide healthcare services for some hea…
Robust Operating Room Scheduling Model with Violation Probability Consideration under Uncertain Surgery Duration
This paper proposes an operating room (OR) scheduling model to assign a group of next-day patients to ORs while adhering to OR availability, priorities, and OR overtime constraints. Existing studies usually consider OR scheduling problems by ignoring the influence of uncertainties in surgery durations on the OR assignment. In this paper, we address this issue by formulating accurate patient waiting times as the cumulative sum of uncertain surgery…
