RLLChatBot - ConvAI Submission

Koustuv Sinha, Nicolas Angelard-Gontier, Peter Henderson, Prasanna Parthasarathy, Mike Noseworthy & Joelle Pineau

As a part of a broader ConvAI challenge, we, the Dialog Group of McGill University under the supervision of Dr Joelle Pineau, have trained a chatbot which can converse fluently with human judges with respect to a given article. The articles are chosen from a broad corpus of SQUAD dataset, where topically they vary from politics to sports to general news. The challenge is to have a fluent conversation with the bot, centering around the topic of the article. Current system uses an ensemble of Generative, Retrieval, and rule based models, and a decision agent learned over actual human-bot responses to select the best candidate response at a given time. We ranked third in the human evaluation round and currently competing in the final round to be held alongside NIPS 2017. Our proposal was also recently awarded ParlAI research grant from Facebook.

MongoLive

Github

Browser based utility library for offline synchronization with Remote MongoDB instances

Being my final year project, I was then heavily into the NoSQL world learning the quirks of MongoDB, and came to realize there were no offline solution to MongoDB instances. While CouchDB, another leading NoSQL provider, had its own offline client solution known as PouchDB, MongoDB had none. So in an attempt to help MongoDB developers to have a client-only offline failsafe, and also to recreate some of the features of PouchDB, I started off with this project with the expert guidance of my mentor Ms. Ee Kian Wong.

Features :

  • Offline Data saved in LocalStorage
  • Easy synchronization to remote MongoDB Instance
  • Built in concurrency handler

Caveats :

  • Lots of legacy code, needs to be brushed up
