Learning from Semi-Factuals: A Debiased and Semantic-Aware Framework for Generalized Relation Discovery

no code implementations12 Jan 2024 Jiaxin Wang, Lingling Zhang, Jun Liu, Tianlin Guo, Wenjun Wu

The key challenges of GRD are how to mitigate the serious model biases caused by labeled pre-defined relations to learn effective relational representations and how to determine the specific semantics of novel relations during classifying or clustering unlabeled instances.

Computation Offloading and Resource Allocation in F-RANs: A Federated Deep Reinforcement Learning Approach

no code implementations13 Jun 2022 Lingling Zhang, Yanxiang Jiang, Fu-Chun Zheng, Mehdi Bennis, Xiaohu You

In this paper, by considering time-varying network environment, a dynamic computation offloading and resource allocation problem in F-RANs is formulated to minimize the task execution delay and energy consumption of MDs.

Consistent Style Transfer

1 code implementation6 Jan 2022 Xuan Luo, Zhen Han, Lingkang Yang, Lingling Zhang

Recently, attentional arbitrary style transfer methods have been proposed to achieve fine-grained results, which manipulates the point-wise similarity between content and style features for stylization.

Learning First-Order Rules with Relational Path Contrast for Inductive Relation Reasoning

no code implementations17 Oct 2021 Yudai Pan, Jun Liu, Lingling Zhang, Xin Hu, Tianzhe Zhao, Qika Lin

Relation reasoning in knowledge graphs (KGs) aims at predicting missing relations in incomplete triples, whereas the dominant paradigm is learning the embeddings of relations and entities, which is limited to a transductive setting and has restriction on processing unseen entities in an inductive situation.
