BERTnesia: Investigating the capture and forgetting of knowledge in BERT
Published in BLACKBOXNLP 2020, 2020
In this paper, we probe BERT specifically to understand and measure the relational knowledge it captures.

Explainable Information Retrieval: A Survey
Published in arXiv, 2022
This survey fills a vital gap in the otherwise topically diverse literature of explainable information retrieval. It categorizes and discusses recent explainability methods developed for different application domains in information retrieval, providing a common framework and unifying perspectives.

GeneMask: Fast Pretraining of Gene Sequences to Enable Few-Shot Learning
Published in ECAI 2023, 2023
We learn a new vocabulary of relevant DNA basepair groups using pointwise mutual information and show that it allows for significantly faster pretraining of DNA language models.
