ADA: An Attention-Based Data Augmentation Approach to Handle Imbalanced …
WitrynaMeanwhile, we propose intra-modality GCL by co-training non-pruned GNN and pruned GNN, to ensure node embeddings with similar attribute features stay closed. Last, we fine-tune the GNN encoder on downstream class-imbalanced node classification tasks. Extensive experiments demonstrate that our model significantly outperforms state-of … Witryna13 cze 2024 · A new feature selection method, namely class‐index corpus‐index measure (CiCi) was presented for unbalanced text classification, a probabilistic method which is calculated using feature distribution in both class and corpus. In the field of text classification, some of the datasets are unbalanced datasets. In these datasets, … how much rain in corpus christi

WitrynaRecently deep learning methods have achieved great success in understanding and analyzing text messages. In real-world applications, however, labeled text data are often small-sized and imbalanced in classes due to the high cost of data collection and human annotation, limiting the performance of deep learning classifiers. Therefore, this study … Witryna11 kwi 2024 · Using the wrong metrics to gauge classification of highly imbalanced Big Data may hide important information in experimental results. However, we find that analysis of metrics for performance evaluation and what they can hide or reveal is rarely covered in related works. Therefore, we address that gap by analyzing multiple … Witryna26 maj 2024 · This article explains several methods to handle imbalanced dataset but most of them don’t work well for text data.
