  1. Minimal information for studies of extracellular vesicles (MISEV2023): From basic to advanced approaches

    2024 · Journal of Extracellular Vesicles

    Extracellular vesicles (EVs), through their complex cargo, can reflect the state of their cell of origin and change the functions and phenotypes of other cells. These features indicate strong biomarker and therapeutic potential and have …

  2. JSCN: Joint Spectral Convolutional Network for Cross Domain Recommendation

    2019 · arXiv (Cornell University)

    Cross-domain recommendation can alleviate the data sparsity problem in recommender systems. To transfer the knowledge from one domain to another, one can either utilize the neighborhood information or learn a direct mapping function. However, all …

  3. Joint Deep Modeling of Users and Items Using Reviews for Recommendation

    2017

    A large amount of information exists in reviews written by users. This source of information has been ignored by most of the current recommender systems while it can potentially alleviate the sparsity problem and improve …

  4. Texygen: A Benchmarking Platform for Text Generation Models

    2018 · arXiv (Cornell University)

    We introduce Texygen, a benchmarking platform to support research on open-domain text generation models. Texygen has not only implemented a majority of text generation models, but also covered a set of metrics that evaluate the …

  5. Spectral collaborative filtering

    2018

    Despite the popularity of Collaborative Filtering (CF), CF-based methods are haunted by the cold-start problem, which has a significantly negative impact on users' experiences with Recommender Systems (RS). In this paper, to overcome the aforementioned …

  6. Lifelong Sequential Modeling with Personalized Memorization for User Response Prediction

    2019

    User response prediction, which models the user preference w.r.t. the presented items, plays a key role in online services. With two-decade rapid development, nowadays the cumulated user behavior sequences on mature Internet service platforms have …

  7. Texygen

    2018

    We introduce Texygen, a benchmarking platform to support research on open-domain text generation models. Texygen has not only implemented a majority of text generation models, but also covered a set of metrics that evaluate the …

  8. Continuous-Time Sequential Recommendation with Temporal Graph Collaborative Transformer

    2021

    In order to model the evolution of user preference, we should learn user/item embeddings based on time-ordered item purchasing sequences, which is defined as Sequential Recommendation~(SR) problem. Existing methods leverage sequential patterns to model item …
