Web18 de dez. de 2024 · In this paper, we propose hierarchy–aware multiclass AdaBoost, allowing for the first time weak classifiers in an ensemble learning setting to be trained for hierarchical multiclass classification while incorporating a hierarchy–aware loss function directly into the training process. Experimental results on numerous real–world datasets ... 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. The state-of-the-art relies on distant supervision and is susceptible to noisy labels that can be out-of-context or overly-specific relative to the training example. Previous methods that attempt to address this ...

Hierarchy-aware Loss Function on a Tree Structured Label Space …
WebThe paper introduces a hierarchy-aware loss function in a Deep Neural Network for an audio event detection task that has a bi-level tree structured label space. The goal is not only to improve audio event detection performance at all levels in the label hierarchy, … Web1 de mai. de 2024 · Rank based loss has two promising aspects, it is generalisable to hierarchies with any number of levels, and is capable of dealing with data with … Web28 de abr. de 2024 · To bridge the gap, in this paper, we propose HPT, a Hierarchy-aware Prompt Tuning method to handle HTC from a multi-label MLM perspective. Specifically, we construct a dynamic virtual template and label words that take the form of soft prompts to fuse the label hierarchy knowledge and introduce a zero-bounded multi-label cross … philosophy gone wild
