- Trained on Reddit Data

The chatbot is trained on Reddit Data using Tensorflow Neural Machine Translation (nmt). This model is based on Encoder-Decoder Architecture. It uses a concept that training a chatbot is similar to training a machine translation (Engish - Japanese) model , the only differnce being that it is English - English translation. The training data had 740k samples of question-answer pairs. Its training files were prepared on google Colab. The Chatbot was trained on 512x3 neural network for 100k epochs with batch size of 64 . It was trainedon AWS t2xLarge for about 10 days ( non-GPU ). The hyperparameters were set to fit the constraints of the server we had.(16GB RAM). It can be improved if the number of epochs are increased as there was enough data.
Since Reddit data is a little slang and doesn't contain proper answers to some trivial qustions, same is true for out chatbot also.
The Chatbot is currently deployed and running on AWS ec2 instance - t2micro (free-tier).

Next, We are working on to make chatbot a bit specific to answer health related queries of people like queries regarding a particular disease, Corona Virus etc. Even the model to answer corona virus related questions is ready but we could not deploy that live due to server constraints.
- Windows
EVA is the native windows executable software. The GUI is developed using Electron-JS .Some node modules used are - IPC Listener,PythonShell etc. It can also run in background,minized in system tray. So, just start the Desktop and start shooting questions of any sort.
- Android App
It only covers only chatbot part as all native Desktop functionalities could not be migrated to Android. The App is developed in React Native. It used React-Native Paper Elements for styling and utilises the chatbot hosted on AWS instance.
- CLI
All functionalities can also be used with command line python interface.
