The Promises and Challenges of Chatbots in Software Engineering

Chatbots are envisioned to dramatically change the future of software engineering, allowing practitioners to chat and inquire about their software projects and interact with different services using natural language. In this talk, we will present our work that proposes a framework that uses chatbots to support software engineering tasks, and identifies challenges that developers face when developing these chatbots, including a comparison of popular Natural Language Understanding (NLU) platforms. We will then finish with a demo and our experience deploying a real-world chatbot called AskGit.

Deep Learning 2.0: Extending the Power of Deep Learning to the Meta-Level

Deep Learning (DL) has been incredibly successful, due to its ability to automatically acquire useful representations from raw data by a joint optimization process of all layers. However, despite this joint optimization of the network weights, current DL practice still requires substantial efforts to manually optimize on the meta-level to define the neural architecture and training hyperparameters for the data at hand. The next logical step is to jointly optimize these components as well, based on meta-level learning and optimization. I predict that this will allow the next generation of DL systems to simply accept data and user objectives to optimize for (which can, e.g., include fairness, robustness, uncertainty calibration, interpretability, etc) and to thereby provide a clean interface between domain experts (who best know the data and the relevant objectives for the application at hand, but do not need to be machine learning experts) on the one hand and the next-generation DL system on the other hand. In this talk, I will discuss several advances towards this goal, focussing on (1) the joint optimization of several meta-choices in the DL pipeline and (2) the efficiency of this meta-optimization, and (3) taking into account user objectives other than performance.
