In today's highly computerized environment, large amounts of data are created every second. These unprocessed data can be from multiple information sources (e.g., mobile phones calls, SMS, GPS locator, emails, tweets, social networking sites, etc.) and/or from data sources that are distributed in nature (e.g., wireless sensor networks, distributed data mining systems, cloud computing systems, etc.). They are often high dimensional, scattered, and non-stationary, but the relevant information about the underlying processes of interest generally lies in a lower dimensional embedding space of a few parameters.

520 $a In today's highly computerized environment, large amounts of data are created every second. These unprocessed data can be from multiple information sources (e.g., mobile phones calls, SMS, GPS locator, emails, tweets, social networking sites, etc.) and/or from data sources that are distributed in nature (e.g., wireless sensor networks, distributed data mining systems, cloud computing systems, etc.). They are often high dimensional, scattered, and non-stationary, but the relevant information about the underlying processes of interest generally lies in a lower dimensional embedding space of a few parameters.
520 $a My research goal is precisely to model and analyze large quantities of high-dimensional data that are collected from various sources in a multi-agent system, and to theoretically study the underlying diffusion patterns as the result of a complex web of interactions in a network of agents. To this end, this dissertation is divided into two parts. The first parts focuses on investigating methods for extracting low-dimensional structure from high-dimensional data and adaptively tracking the principal subspace of data streams that are collected at different agents. We also analyze the case of learning the data conveyed from a distributed network using an in-network gossip-based protocol. We show that relatively simple iterative message passing followed by local computations can converge to the optimum solution while reducing the computation burden that arises from centralized processing. This motivates the second part of this thesis, which focuses on the mathematical modeling and theoretical tools for analyzing information propagation and diffusion in networks. We compare models for social learning in the context of economics and social sciences with those used in the study of distributed sensor networks, explaining how consensus emerges or fails to emerge in both scenarios. Furthermore, we investigate various local interaction models in social networks with an emphasis on the situation where agents interact more strongly with the agents that have similar beliefs. The question that we seek to address is how social interactions lead to the formation of opinions in a social group.
