Oral Outstanding Paper Award | ICLR 2021

https://arxiv.org/pdf/2011.03459.pdf
Complex query answering with neural link predictors.

We 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/
A platform for real-time analysis and prediction of current touristic activities in Armenia based on deep learning methods.

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/deeplanguageclass
Lectured and held workshops on NLP topics.

I 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/
Founder.

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/
Created a library for differentiable machine learning based on PyTorch for classic, parametric, and learnable T and S-norms.

The library supports the seamless addition of new differentiable modules and supports complete CI/CD for safety.
