RDP LoRA: Geometry-Driven Identification for Parameter-Efficient Adaptation in Large Language Models

Yusuf Çelebi, Yağız Asker, Özay Ezerceli +4

Fine-tuning Large Language Models (LLMs) remains structurally uncertain despite parameter-efficient methods such as Low-Rank Adaptation (LoRA), as the layer-specific roles of inter…

Beyond Cosine Similarity: Taming Semantic Drift and Antonym Intrusion in a 15-Million Node Turkish Synonym Graph

Ebubekir Tosun, Mehmet Emin Buldur, Özay Ezerceli +1

Neural embeddings have a notorious blind spot: they can't reliably tell synonyms apart from antonyms. Consequently, increasing similarity thresholds often fails to prevent opposite…

TurkColBERT: A Benchmark of Dense and Late-Interaction Models for Turkish Information Retrieval

Özay Ezerceli, Mahmoud El Hussieni, Selva Taş +4

Neural information retrieval systems excel in high-resource languages but remain underexplored for morphologically rich, lower-resource languages such as Turkish. Dense bi-encoders…
