While forming teams, we realized how tedious the entire process was. Depending on the hackathon, forming teams involves some combination of scrolling through an endless list of posts on a #team-forming slack channel, google sheet, or awkwardly being directed to some corner of the room to meet others. Not only does this waste precious time and is inefficient, many of the postings on the google sheet or slack channel look the same after scrolling through for some time.
FriendlyBot solves all these problems and provides a platform for limitless other opportunities through its highly advanced, custom-built-from-ground-up learning algorithms.
What it does
Through FriendlyBot, teams can seamlessly find individuals to recruit to their team based on the skills they need. For individuals looking for teams, FriendlyBot enables them to discover teams to join based on their skill-set and projects they are most likely to be interested in, determined through FriendlyBot's advanced algorithms.
How we built it
FriendlyBot's NLU backend parses structured data from user queries by generating embedding representations of user queries using a siamese LSTM (deep recurrent neural networks). It is optimized for GPU computing, with computing costs lowered to the extent that it can in fact be run on a 14 year old's laptop.
Challenges we ran into
We ran into various challenges while building FriendlyBot. The first set of issues were setting up the webhooks to work with our local development environment. While we tried popular tunneling solution ngrok, it served to no avail, and we were resorted to keeping it deployed on the Heroku platform. In addition, the Facebook Graph API was challenging to use, particularly Facebook Auth.
Challenges while building the natural language understanding engine involved dealing with managing high-dimensional spaces and mapping out boundaries for clusters required for classification. Because of the length of the average human sentence, we had to account for exploding and disappearing gradients by using a special variation of a recurrent neural network that was a siamese LSTM first implemented by a MIT professor just a few months ago.
