EDDIE: A Knowledge-Backed QA Agent

Built an open-domain, contextual, conversational QA agent using modified DrQA, BERT and PGNet architectures It has a document retriever, neural reader, clarifying system and an answer ranking moduleTrained an attentive stacked biLSTM model having 45% F1 accuracy on QuAC dataset. Used attentive history embeddings for contextImproved the retriever accuracy (% match in top 5 doc) from 11% to 64% by adding previous QA pairs and topic as context in queries to retrieverResearch Project | Team Size: 1 | Jan'19 - Dec'19 | Github Repo Technologies: Python, PyTorch, NLP, Information Retrieval

Adversarial Question Generation

Built a framework that generates questions, using transformer based uniLM model, on which a given QA system fails. Trained a 2 layer neural network classifier on failed questions (using infersent embeddings) of a given QA system (BiDAF, BERT based) to classify above generated questions as unanswerable/answerable, with 65% accuracy Research Project | Team Size: 3 | Sep'19 - Oct'19 | Github Repo Technologies: Python, PyTorch, ML, NLP

BKPFS: A Backup File System

Developed a backup file system, BKPFS, using a stackable file system WRAPFSBKPFS creates a hidden backup directory and multiple backup files per file to backup any modifications to the file. Users can use ioctls to list, view, recover or delete any of the backups. Wrote ~2000 lines of kernel code to implement system calls, ioctl commands, visibility and retention policies.
