Weighted-Rank Contrastive Regression for Robust Learning on Imbalance Social Media Popularity Prediction
Keywords: Social Media Popularity Prediction, Contrastive Learning, Imbalance Regression, Rank-N-Contrast, Social Media Prediction Dataset
Abstract: Social Media Popularity Prediction (SMPP) is the task of forecasting the level of engagement a social media post will receive. It is crucial
for understanding audience engagement and enabling targeted marketing strategies. However, the inherent imbalance in real-world
social media data, where certain popularity levels are underrepresented, poses a significant challenge. In this study, we leveraged the
recent success of contrastive learning and its growing integration into regression tasks by introducing a Weighted-Rank CR loss to
address the data imbalance challenges. Experiments on the Social Media Prediction Dataset demonstrated that our method outperformed
the vanilla approach and the current state-of-the-art contrastive regression approach Rank-N-Contrast.
