Masked Autoencoders (MAEs) represent a significant shift in self-supervised learning (SSL) due to their independence from augmentation techniques for generating positive (and/or negative) pairs as in contrastive frameworks. Their masking and reconstruction strategy also aligns well with SSL approaches in natural language processing. Most MAEs are built upon Transformer-based architectures where visual features are not regularized as opposed to their convolutional neural network (CNN) based counterparts, which can potentially limit their effectiveness. To address this, we introduce a novel batch-wide layer-wise regularization loss applied to representations of different Transformer layers. We demonstrate that by plugging in the proposed regularization loss, one can significantly improve the performance of MAE-based baselines.

Moral values play a crucial role in our decision-making process by defining what is right and wrong. With the emergence of political activism and moral discourse on social media, and the latest developments in Natural Language Processing, we are looking at an opportunity to analyze moral values to observe trends as they form. Recent studies have extensively examined the performance of different NLP models for estimating moral values from text, but none of them has tackled the problem of transfer learning. Our study provides a comprehensive look into the cross-domain performance of three state-of-the-art models. We find that BERT, the current most used model in Natural Language Processing, offers the best results. For reproducibility, we publicly release our code on GitHub.
