| 題目(Title): | Data-efficient Skill Transfer for Robotics using Virtual Reality and Imitation Learning |
| 概要(Abstract)： | Imitation Learning (IL) is a paradigm where humans demonstrate the procedure to perform complex tasks which can be used to train autonomous agents. However, the performance of IL is highly sensitive to the quality of demonstrations which in turn depends on the user-interface. In this presentation, we propose the use of Virtual Reality (VR) to develop an intuitive interface that enables users to provide good demonstrations. We apply this approach to the task of training a visual attention system which is a crucial component for tasks such as autonomous driving and human-robot interaction. We show that interaction time of a few minutes is sufficient to train a deep neural network to successfully learn attention strategies. |

| 題目(Title)： | On Updating Library Dependencies in Open Source Sofware Projects |
| 概要(Abstract)： | Third-party library reuse is now common practice in contemporary software development, as it includes several benefits for developers. Library dependencies are constantly evolving, with newly added features and patches that fix bugs in older versions. To take full advantage of resuse, developers should always keep up to date with the latest versions. In this presentation, I will introduce to work related to library updates and the issues faced. The first study is an empirical study on library migration. We show how libraries are not been updated, even when the updates include vulnerabilities. In the second study, we introduce our software universal graph model to help with library usage and updates. We show how the model can be utilized in the form of visualization and has been used to build tools that will assist developers to update their third-party libraries. |
