DECSELFMASK: Leveraging Unlabeled Text via Self-Relevance-Guided Masking for Decoder-Only Classification

arXiv:2606.09466v2 Announce Type: replace Abstract: Classification tasks require annotated data, which can often be expensive, time-consuming, or even unfeasible to collect. This is the case of the medical domain, where large datasets often have few annotated examples. To address this, we propose DecSelfMask (Decoder Self-learning by Masking), an approach to enhance decoder-only performance on classification tasks. We build on common self-learning approaches by leveraging a model to create training examples from unlabeled data to propose a novel relevance-guided masking strategy. We use releva

Why this matters
Why now

The increasing demand for specialized AI applications, particularly in fields with limited annotated data like medicine, is driving innovation in self-supervised learning techniques.

Why it’s important

This development allows for more efficient and robust classification models with less reliance on costly and time-consuming human-annotated datasets, accelerating AI deployment in critical sectors.

What changes

The barrier to entry for developing high-performing AI models in data-scarce domains is lowered, making AI more accessible and enabling new applications in fields like medical diagnosis.
