Captsone Project

Capstone Project

QABot: A Chatbot for Open Question Answering Using Neural Networks

QABot: A Chatbot for Open Question Answering Using Neural Networks: Built “QABot”, a Chatbot using the sequence-to-sequence Deep Learning model that utilizes the Encoder Decoder Neural Network architecture combined with Attention Mechanism to answer user search queries. Created a model by training a Deep Neural using the PyTorch Deep Learning Framework. Used Recurrent Neural Network architecture that are better at dealing with text sequences. Used both Teacher Forcing and Auto-Regressive approaches for model training and Auto-Regressive approach for model evaluation. Used BERT (Bidirectional Encoder Representations from Transformers) for tokenization and combined Transformer and GPT-2 for model fine tuning.
