Experience

ML Researcher, 2022-2024

Database and Dependable Computing Lab

Ajou University, Suwon, South Korea

Extracting Low-Resource Datasets for Affordable Adaptation of LLMs:

  • Processed > 1000 TB of Common Crawl for < 2 $, extracting SOTA monolingual datasets for 7 languages.
  • Improved multi-lingual LLMs using Quantized Low-Rank Adaptation (QLoRA) on consumer GPUs.
  • Published in Proceedings of Symposium of the Korean Institute of Communications and Information Sciences.
  • Code released at “UnifiedCrawl

Generalized Output Spaces for Classifiers:

  • Improved cross-domain/cross-task generalization of multi-modal classifiers by fusing descriptions of classes/tasks.
  • Achieved SOTA zero-shot performance on CIFAR, RCV1, 20 NG (under review for publication).

Projects & Open Source Contributions

Information Retrieval for Low-Resource Languages (2022)

  • Trained a BERT-like transformer Language-Model (LM) for IR for African languages.
  • Compared traditional IR approaches (tf-idf, BM25) vs. SOTA approaches.

Open Source Contributions

  • Added support for more languages to “AllTrans”, an android application translator.
  • Added extra languages to “Android-Auto-Localization”, to localize Android application’s resources.
