 Title: Opportunities and Challenges in Using the Power of the Crowd: Incentive Mechanisms, Truth Discovery, and Robustness

With the proliferation of smart mobile devices and the popularity of social networks, crowdsourcing has emerged as a new computing and sensing paradigm, which uses collective power/intelligence of the crowd to accomplish computing or sensing tasks. For crowdsourcing to be useful, we need good incentive mechanisms to attract more users to participate in the activity, we need reliable methods to find the truth from the crowdsourced data. The system also needs to be robust against various attacks, and be able to resolve dispute between the task owners and the work providers. In this talk, we will discuss the crowdsourcing computing paradigms, truthful incentive mechanisms, Sybil attacks and counter-measures, truth discovery via supervised learning and unsupervised learning, and dispute resolution, along with open research issues.

Title: Distributed Learning for Big Data Analytics: From Cloud to Edge

When accessing cloud-hosted modern applications, users often suffer a significant latency due to the long geo-distance to the central cloud. Edge computing thus emerges as an alternative paradigm that can reduce this latency by deploying services close to users. In this talk, we will analyze the methodology and limitations of popular approaches for supporting AI services on geo-distributed systems along the evolution from cloud computing to edge computing. In particular, we shall discuss how to deal with different sets of challenges in training and inference, the two phases of machine learning based applications, over heterogeneous geo-distributed systems. We shall also present our recent studies on data driven resource management among networked collaborative edges.
