ukraine-war-pov

This model is a fine-tuned version of xlm-roberta-base on a dataset of 30K social media posts (a balanced set of 15K for each label) from Ukraine manually annotated for pro-Ukrainian or pro-Russian point of view on the war after the 2022 invasion. It achieves the following results on a balanced test set (2K):

• Loss: 0.2166
• Accuracy: 0.9315
• F1: 0.9315
• Precision: 0.9315
• Recall: 0.9315
• AUC: 0.9774 (self-report)
