LTG-Oslo Hierarchical Multi-task Network: The importance of negation for document-level sentiment in Spanish

2019-06-18 · Jeremy Barnes

This paper details LTG-Oslo team's participation in the sentiment track of the NEGES 2019 evaluation campaign. We participated in the task with a hierarchical multi-task network, which used shared lower-layers in a deep BiLSTM to predict negation, while the higher layers were dedicated to predicting document-level sentiment. The multi-task component shows promise as a way to incorporate information on negation into deep neural sentiment classifiers, despite the fact that the absolute results on the test set were relatively low for a binary classification task.

OSLO: One-Shot Label-Only Membership Inference Attacks

2024-05-27 · Yuefeng Peng, Jaechul Roh, Subhransu Maji, Amir Houmansadr

We introduce One-Shot Label-Only (OSLO) membership inference attacks (MIAs), which accurately infer a given sample's membership in a target model's training set with high precision using just \emph{a single query}, where…
