    abstract = "Our study explores multi-label emotion classification using fine-tuned BERT models, achieving superior performance over traditional methods such as logistic regression. The intricate nature of overlapping emotional expressions in text necessitates a robust classification framework. Fine-tuning BERT with weighted binary cross-entropy loss enhances predictive accuracy, particularly for underrepresented emotions like anger and joy. Moreover, threshold optimization plays a pivotal role in refining decision boundaries, boosting recall, and increasing the macro F1-score. Comparative analysis against RoBERTa and XGBoost further underscores the effectiveness of contextual embeddings in capturing subtle emotional nuances. Despite these improvements, challenges such as class imbalance and inter-class confusion persist, highlighting the need for future advancements in ensemble learning, contrastive pretraining, and domain-adaptive fine-tuning."
