Papers with Hawkes process
Suicide Ideation Detection via Social and Temporal User Representations using Hyperbolic Learning (2021.naacl-main)
Copied to clipboard
| Challenge: | Recent studies indicate that individuals exhibiting suicidal ideation increasingly turn to social media rather than mental health practitioners. |
| Approach: | They propose a framework leveraging a user’s emotional history and social information from a users neighborhood in a network to contextualize the interpretation of the latest tweet of a Twitter user. |
| Outcome: | The proposed framework outperforms state-of-the-art methods on this task, showing the benefits of both socially and personally contextualized representations. |
Modeling User Satisfaction Dynamics in Dialogue via Hawkes Process (2023.acl-long)
Copied to clipboard
| Challenge: | Existing estimators measure performance by user satisfaction but ignore satisfaction dynamics across turns. |
| Approach: | They propose to use user satisfaction estimation to estimate performance of dialogue systems by using an estimator to simulate users. |
| Outcome: | The proposed estimator outperforms existing estimators on four benchmark dialogue datasets. |
Graph Hawkes Transformer for Extrapolated Reasoning on Temporal Knowledge Graphs (2022.emnlp-main)
Copied to clipboard
| Challenge: | Existing methods for entity prediction cannot predict when an event will occur . there are many facts not related to the query that can confuse the model . |
| Approach: | They propose a temporal knowledge Graph reasoning model based on Graph Hawkes Transformer . the model captures instantaneous structural and temporal evolution information . |
| Outcome: | The proposed model performs much better under long-term evolution scenarios. |
