A story of viral co-infection, co-transmission and co-feeding in ticks: how to compute an invasion reproduction number

1 code implementation22 Mar 2024 Giulia Belluccini, Qianying Lin, Bevelynn Williams, Yijun Lou, Zati Vatansever, Martín López-García, Grant Lythe, Thomas Leitner, Ethan Romero-Severson, Carmen Molina-París

We show that a simple model, with two populations of ticks infected with one strain, resident or invasive, and one population of co-infected ticks, does not have Alizon's neutrality property.

Iterative Memory Network for Long Sequential User Behavior Modeling in Recommender Systems

no code implementations29 Sep 2021 Qianying Lin, Wen-Ji Zhou, Yanshi Wang, Qing Da, Qing-Guo Chen, Bing Wang

Extensive empirical studies show that our method outperforms various state-of-the-art sequential modeling methods on both public and industrial datasets for long sequential user behavior modeling.

Learning-To-Ensemble by Contextual Rank Aggregation in E-Commerce

no code implementations19 Jul 2021 Xuesi Wang, Guangda Huzhang, Qianying Lin, Qing Da

Combined with the idea of Bayesian Optimization and gradient descent, we solve the online contextual Black-Box Optimization task that finds the optimal weights for sub-models given a chosen RA model.

Diversity Regularized Interests Modeling for Recommender Systems

no code implementations23 Mar 2021 Junmei Hao, JingCheng Shi, Qing Da, AnXiang Zeng, Yujie Dun, Xueming Qian, Qianying Lin

Each interest of the user should have a certain degree of distinction, thus we introduce three strategies as the diversity regularized separator to separate multiple user interest vectors.
