Experience
Oral Outstanding Paper Award | ICLR 2021
https://arxiv.org/pdf/2011.03459.pdfWe proposed a framework for efficiently answering complex queries on incomplete Knowledge Graphs. We translated each question into an end-to-end differentiable objective, where a pre-trained neural link predictor computes the truth value of each atom.
Travelinsights
https://www.travelinsights.ai/The tool allows for scalable real-time analysis of events, sentiments, topics, and insights into Armenia's touristic activities and trends.
Fifth Summer School on Mathematics and Applications at YSU
https://github.com/deeplanguageclassI created models for Armenian Transliteration and pipelines for Armenian Lemmatization and semantic segmentation.
Worked on improving word embeddings and held NLP workshops and sessions.
FastEnt
https://fastent.github.io/Created a pipeline for automated custom named entity recognition and disambiguation. Developed pipelines for continuous scraping and dataset generation and implemented robust methods for named entity generalization and detection.
TorchNorms
https://pypi.org/project/torchnorms/The library supports the seamless addition of new differentiable modules and supports complete CI/CD for safety.
