Fine-tuning and Sampling Strategies for Multimodal Role Labeling of Entities under Class Imbalance
Résumé
We propose our solution to the multimodal semantic role labeling task from the CON-STRAINT’22 workshop. The task aims at clas-sifying entities in memes into classes such as “hero” and “villain”. We use several pre-trained multi-modal models to jointly encode the text and image of the memes, and implement three systems to classify the role of the entities. We propose dynamic sampling strategies to tackle the issue of class imbalance. Finally, we per-form qualitative analysis on the representations of the entities.
