Web6 de nov. de 2024 · Conventional classifiers trained with the cross-entropy loss treat all misclassifications equally. However, certain categories may be more semantically related to each other than to other categories, implying that some classification mistakes may be more severe than others. For instance, an autonomous vehicle confusing a car for a truck is … Web9 de mar. de 2024 · The task of Fine-grained Entity Type Classification (FETC) consists of assigning types from a hierarchy to entity mentions in text. Existing methods rely on distant supervision and are thus susceptible to noisy labels that can be out-of-context or overly-specific for the training sentence. Previous methods that attempt to address these …
