G-Loss: Graph-Guided Fine-Tuning of Language Models
Traditional loss functions for fine-tuning pre-trained language models like BERT overlook global semantic structure. This paper introduces G-Loss, a graph-guided loss function that integrates semi-supervised label propagation and dynamic graph construction. G-Loss captures global semantic relationships, resulting in more discriminative and robust embeddings. Evaluated across five benchmark datasets, G-Loss shows faster convergence and higher classification accuracy compared to traditional methods, producing semantically coherent embedding spaces.
Executive Impact

G-Loss: A Graph-Guided Fine-Tuning Framework
G-Loss shifts language model fine-tuning from local pairwise optimization to global structural alignment. By integrating a dynamically constructed semantic graph and semi-supervised Label Propagation Algorithm (LPA), G-Loss ensures both local and multi-hop consistency in the embedding manifold. This approach leads to more robust and discriminative representations, crucial for enterprise-grade NLP tasks.

Scalability and Generalization for Enterprise Deployments
G-Loss demonstrates strong generalization ability across various language models (BERT-base, RoBERTa-large, DistilBERT) and challenging GLUE benchmarks (SST-2, QNLI). Its dynamic mini-batch graph construction ensures computational efficiency, making it suitable for real-world enterprise applications without the overhead of full-graph methods.
Case Study: Enhanced Sentiment Analysis with RoBERTa-large
When combined with RoBERTa-large, G-Loss achieved new state-of-the-art results on the Movie Review (MR) dataset with 90.82% accuracy, a significant improvement over traditional methods. On the QNLI benchmark, G-Loss + RoBERTa-large scored 94.27% accuracy, demonstrating its robustness for large-scale natural language inference. This highlights G-Loss's capability to deliver superior performance even with larger, more complex base models, bridging the gap between graph-based and transformer-based paradigms more efficiently.
