Zero-Shot Text Classification with Self-Training

2022 · arXiv (Cornell University)

Recent advances in large pretrained language models have increased attention to zero-shot text classification. In particular, models finetuned on natural language inference datasets have been widely adopted as zero-shot classifiers due to their promising results …

Guided Query Refinement: Multimodal Hybrid Retrieval with Test-Time Optimization

2025 · arXiv (Cornell University)

Multimodal encoders have pushed the boundaries of visual document retrieval, matching textual query tokens directly to image patches and achieving state-of-the-art performance on public benchmarks. Recent models relying on this paradigm have massively scaled the …
