Speech Title: Connecting Isolated Social Multimedia Big Data

Abstract: The explosion of social media has led to various Online Social Networking (OSN) services. Today's typical netizens are using a multitude of OSN services. Exploring the user-contributed cross-OSN heterogeneous data is critical to connect between the separated data islands and facilitate value mining from big social multimedia. From the perspective of data fusion, understanding the association among cross-OSN data is fundamental to advanced social media analysis and applications. From the perspective of user modeling, exploiting the available user data on different OSNs contributes to an integrated online user profile and thus improved customized social media services. This talk will introduce a user-centric research paradigm for cross-OSN mining and applications and some pilot works along two basic tasks: (1) From users: cross-OSN association mining and (2) For users: cross-OSN user modeling.

He is a Fellow of IEEE.

Speech Title: Bridging Vision and Language for Image Captioning

Abstract: As human beings, we can use our vision capabilities and language to perceive the world around us and to communicate with each other. While it seems to be easy for human beings to accomplish a wide variety of tasks that combine the two modalities, it is quite challenging for machines because it requires the model to understand both images and language, especially how they relate to each other. In this talk, I will discuss a few of my group’s recent works to bridge images and natural language via leveraging language inductive bias for the application of image captioning. I will also touch the future directions along this line.

Speech Title: The Power of Differential Privacy for Secure Data Sharing

Abstract:  In the era of cloud computing with the evolving demand of big data processing, privacy-preserving computing (PPC) has arisen as an effective way to achieve secure distributed computing and information sharing which serves as the base for realization of widespread Smart City and e-Society. PPC requires to develop a computation paradigm for solving a given problem that takes privacy-protected data as input and produces an output that is utilizable to the public yet secure against privacy attacks. There is a rich literature on the topic and numerous advancements have appeared in the past decade with the focus on improved security against various privacy attacks in the cloud computing environment. In these PPC paradigms, the demand of security assurance against emerging privacy attacks makes the task of maintaining output's utility to public become ever more challenging. In the first part of this talk, I will first introduce the problem of privacy-preserving computing, its research challenges in cloud big data computing, then give a taxonomy on data protection techniques categorized on the security levels of data publishing, with the focus on differential privacy as an effective method to combat inference attacks, and provide an overview on our contributions in privacy-preserving computing. In the second part, to show the power of differential privacy for secure data sharing, I will give two examples of our work of applying differential privacy to achieve privacy-preserving recommendation and data clustering against inference attacks. As concluding remarks, I will further illustrate the application of differential privacy in obtaining privacy-preserving solutions for some statistical and combinatorial optimization problems.
