This paper addresses our approach to Task 11 (Track A and B) at the SemEval-2025, which focuses on the challenge of multilingual emotion detection in text, specifically identifying perceived emotions. The task is divided into tracks, we participated in two tracks: Track A, involving multilabel emotion detection, and Track B, which extends this to predicting emotion intensity on an ordinal scale. Addressing the challenges of imbalanced data and linguistic diversity, we propose a robust approach using pre-trained language models, fine-tuned with techniques such as extensive and deep hyperparameter optimization, along with loss function combinations to improve performance on imbalanced datasets and underrepresented languages. Our results demonstrate strong performance on Track A, particularly in low-resource languages such as Tigrinya (ranked 2nd), Igbo (ranked 3rd), and Oromo (ranked 4th). This work offers a scalable framework for emotion detection with applications in cross-cultural communication and human-computer interaction.
