Title: On Federated Learning and Personalized Information Processing 

Abstract: As a distributed learning architecture with data isolation training and user privacy protection mechanism, federated learning has received extensive attentions from academia and industry. However, federated learning still faces the great challenges of  the heterogeneity of multiuser data, the heterogeneity of different agent computing capability and the diversity of communication channels as well as the imbalance and correlation of multi-category data distributions etc. In this talk, we shall introduce a new personalized information processing technique. We first introduce a centralized mode data learning model under the general model, and use it as a benchmark to give the theoretical performance upper bound of the data processing mode under the federal mechanism. Based on the theoretical limit, we formulate an optimization problem for personalized information processing, and use the principle of water-filling in information theory to derive the explicit expression of the optimal data weights. Then database test is used to verify the effectiveness of the theoretical scheme, and some system design principles of theoretical interpretability are also given. Finally, we also point out the potential application scenarios of this new developed approach and its new progresses in Vehicular Edge computing.

Title:Environmental Sustainability and Intelligence as well as General Green Technologies

Abstract: Although the term of green has been often used to refer to energy consumption reduction or energy efficiency by many people and literatures, green actually should refer to environmental sustainability in more general senses. Environmental sustainability issues have been important topics for recent years, which has impacted and will further impact individuals, enterprises, governments, and societies. Environmental sustainability is not simply regarding reducing the amount of waste or using less energy, but relevant to developing processes leading to completely sustainable human society in the future. The long term consequences of the relevant serious issues have not yet been fully forecasted, but it has been generally accepted in many communities that immediate responses are necessary. From 30 November to 12 December 2015, the 21th United Nations Climate Change Conferences of the Parties (COP 21) was held in Paris, France, as the a historical breakthrough and milestone towards securing the future Earth, a global agreement on the reduction of climate change, the text of which represented a consensus of the representatives of more than 193 countries attending it, which was a profound milestone for global environmental sustainability. Nowadays there is another significant tendency on data driven intelligence. This talk would discuss the history, technical issues, challenges, and new trends of data driven environmental sustainability and Intelligence. Further this talk will extend the view to general green technologies.
