Title: Federated Learning of Structure Discovery and Rule-Based Systems With Privacy Constraints

Abstract: Quite often in real-world environment, data can be available only locally coming with strict constraints imposed on their usage beyond individual data islands. Such restrictions constitute genuine conceptual and algorithmic challenges when it comes to solving problems of global data analysis and the development of global models. A lot of pursuits located in this realm fall under the umbrella of federated learning where this learning paradigm is linked with the computing ideas of cloud computing.

The discovery of the structure of data to be realized at the global level becomes highly demanding given the required privacy of attributes to address the existing challenge, a number of ways of conceptualization of the collaborative clustering are discussed. In spite of the diversity of the ensuing optimization mechanism, it is worth stressing that building a global structure is completed at a higher level of abstraction. Subsequently, it is shown that a sound conceptual setting involves concepts of information granules and mechanisms of Granular Computing. The quality of constructed relationships is also analyzed at the level of granular constructs. The accommodation of privacy constraints in the design of rule-based architectures with the rules assuming the form “if condition is Ai then y=fi(x), i=1,2,...,c is elaborated in detail. The attributes not publicly available are expressed through information granules Ai built through collaborative clustering whereas remaining attributes (x) are used in the construction of the local functions. A way of forming the rules through unsupervised federated learning is investigated along with the detailed algorithmic developments. A granular characterization of the obtained model formed by the server vis-a-vis data located at the level of individual clients is discussed and a number of case studies is studied.

Title: Blockchain and Zero-trust Computing

Abstract: Blockchain has emerged as a new technology to enable multiple agents to complete transactions that require strong security and reliability, even though these agents do not trust each other and the media supporting their interactions is not trustworthy. Such a property drives zero-trust computing to come into being, which is a computing paradigm supporting collaborative computing services in a zero-trust environment. In this talk, we first introduce zero-trust computing, using the evolutions of cryptocurrency, web, and computing paradigms as examples to demonstrate why zero-trust computing plays fundamental and critical roles in enabling the exciting applications driven by the next-generation Internet technologies in the coming years. Then we talk about the open challenges of blockchain and zero-trust computing whose solutions can nurture various zero-trust based applications that are expected to burgeon in the near future. Finally we report our effort in blockchain and zero-trust computing, serving as a catalyst for further studies to advance zero-trust computing technologies and their applications.
