Online Detection of Anomalies in Temporal Knowledge Graphs with Interpretability

1 code implementation1 Aug 2024 Jiasheng Zhang, Rex Ying, Jie Shao

When new knowledge emerges, AnoT maps it onto a node in the rule graph and traverses the rule graph recursively to derive the anomaly score of the knowledge.

DTGB: A Comprehensive Benchmark for Dynamic Text-Attributed Graphs

1 code implementation17 Jun 2024 Jiasheng Zhang, Jialin Chen, Menglin Yang, Aosong Feng, Shuang Liang, Jie Shao, Rex Ying

Moreover, we conduct extensive benchmark experiments on DTGB, evaluating 7 popular dynamic graph learning algorithms and their variants of adapting to text attributes with LLM embeddings, along with 6 powerful large language models (LLMs).

StreamE: Learning to Update Representations for Temporal Knowledge Graphs in Streaming Scenarios

2 code implementations journal 2023 Jiasheng Zhang, Jie Shao, Bin Cui

To reduce the parameter size, entity representations in StreamE are decoupled from the model training to serve as the memory module to store the historical information of entities.

Privacy Preserving in Non-Intrusive Load Monitoring: A Differential Privacy Perspective

no code implementations12 Nov 2020 Haoxiang Wang, Jiasheng Zhang, Chenbei Lu, Chenye Wu

In this paper, we cast one-shot non-intrusive load monitoring (NILM) in the compressive sensing framework, and bridge the gap between theoretical accuracy of NILM inference and differential privacy's parameters.

Treat the Word As a Whole or Look Inside? Subword Embeddings Model Language Change and Typology

1 code implementation WS 2019 Yang Xu, Jiasheng Zhang, David Reitter

We use a variant of word embedding model that incorporates subword information to characterize the degree of compositionality in lexical semantics.
