Title: LLMs can construct powerful representations and streamline sample-efficient supervised learning

Abstract:
arXiv:2603.11679v3 Announce Type: replace Abstract: As real-world datasets become more complex and heterogeneous, supervised learning is often bottlenecked by input representation design. Modeling multimodal data, such as time-series, free text, and structured records, often requires non-trivial domain expertise. We propose an agentic pipeline to streamline this process. First, an LLM analyzes a small but diverse subset of text-serialized input examples in-context to synthesize a global rubric,
