Much research on response selection in conversation systems is modeling the matching patterns between user input message (either with context or not) and response candidates, which ignores external knowledge beyond the dialog utterances. This kernel-based estimation effectively leverages both multiple structural information within a trajectory and the local motion patterns across multiple trajectories, such that the discrimination of the shrunk point can be properly increased. 2018] Our paper VisemeNet accepted by SIGGRAPH 2018. We also study how to integrate user intent modeling into neural ranking models to improve response retrieval performance.

Prof. J. Joshua Yang and his research group focus on Post-CMOS ionic and electronic devices, with applications in unconventional computing technologies. Our goal is to develop effective learning models for answer retrieval and information-seeking conversations, in order to improve the effectiveness and user experience when accessing information with a touch screen interface or a conversational interface, as commonly adopted by millions of mobile Internet devices.
On the other hand, voice-based / text-based conversational interfaces are becoming increasing popular as shown in the wide adoption of intelligent assistant services and devices such as Amazon Echo, Microsoft Cortana and Google Assistant around the world. The audio content robustly controls the motion of lips and nearby facial regions, while the speaker information determines the specifics of facial expressions and the rest of the talking head dynamics.
Collaborate with researchers on 3D facial/skeleton animations based on deep learning approaches.
2019] Joined Adobe CIL (Seattle) as a summer intern. Finally, hybrid models of response retrieval and generation are investigated in order to combine the merits of these two different paradigms of conversation models. ShapeNet is an ongoing effort to establish a richly-annotated, large-scale dataset of 3D shapes.

In this dissertation, we investigate several aspects of single-turn answer retrieval and multi-turn information-seeking conversations to handle the new challenges of search on the mobile Internet. In contrast to previous approaches that fit pre-defined skeleton templates or predict fixed sets of joints, our method produces an animation skeleton tailored for the structure and geometry of the input 3D model.

2019] Our paper SceneGraphNet accepted by ICCV 2019. We propose a 3D tube which can effectively embed both motion and scene-related information of a motion trajectory and a droplet-based method which can suitably catch the characteristics of the 3D tube for activity recognition. The increasing popularity of mobile Internet has led to several crucial changes in the way that people use search engines compared with traditional Web search on desktops. © 2009 University of Massachusetts Amherst • Site Policies, Privacy [New Video!]
Given an input, potentially incomplete, 3D scene and a query location, our method predicts a probability distribution over object types that fit well in that location. It also estimates surface skin weights based on the predicted skeleton.
