        Research Projects

        •  Convolutional Neural Network based Triage Techniques toward Automation of Bug Assignments (NRF project)  
        We aim to develop a deep-learning based automated tool for solving the problem of bug assignments. Recently Convolutional Neural Network (CNN) has shown superior performance not only in multi-media area such as image retrieval but also in text document classifications. We extend the state-of-the-art sentence classification algorithm based on CNN to implement a recommendation system for bug triage. Specifically, our proposed research includes 1) Developing a bug assignment system using CNN, 2) Study on effective word embedding and optimal parameter settings, 3) Devising techniques against imbalance of training data.
