I tried the chatbot - I must admit I'm surprised how well it worked actually! Got me interested, I hope you don't mind a few questions:
When you write 'built i from scratch' what do you mean? That you handcrafted all the data?
How long did it take to develop this bot, and what technologies did you use?
- olavgg 10y agoYes, all the data we use to train our model on, is handcrafted by our AI trainers. What they do is figure out all the different questions that are most common to ask for each intent we want to predict. We have built a tool that helps them creating all these sentences, often we use templates with keywords. It is still under development, we started at the end of last summer. We use Torch and Python-NLTK.
- prokerhov 10y agoWhy have you chosen torch instead of staying completely in python? I assume that you use nltk for tagging, entity regoncition, ... and torch for your classifier. What kind of model is possible in LUA-torch that could not be done in python with caffe/tensorflow?
- olavgg 10y agoBecause it is a lot easier to tune and debug your model in Torch without diving into C/C++. https://news.ycombinator.com/item?id=13428098 https://news.ycombinator.com/item?id=13428098 We may switch to pyTorch though, but Lua works rather well for now.
