Label Augmentation for Zero-Shot Hierarchical Text Classification

ACL 2024long

Hierarchical Text Classification poses the difficult challenge of classifying documents into multiple labels organized in a hierarchy. The vast majority of works aimed to address this problem relies on supervised methods which are difficult to implement due to the scarcity of labeled data in many re…

Invariant Representations with Stochastically Quantized Neural Networks

AAAI 2023technical

Representation learning algorithms offer the opportunity to learn invariant representations of the input data with regard to nuisance factors. Many authors have leveraged such strategies to learn fair representations, i.e., vectors where information about sensitive attributes is removed. These metho…
