Heat Conduction Process on Community Networks as a Recommendation Model
Yi-Cheng Zhang, Marcel Blattner, Yi-Kuo Yu
Using heat conduction mechanism on a social network we develop a systematic method to predict missing values as recommendations. This method can treat very large matrices that are…
Exploring an opinion network for taste prediction: an empirical study
Marcel Blattner, Yi-Cheng Zhang, Sergei Maslov
We develop a simple statistical method to find affinity relations in a large opinion network which is represented by a very sparse matrix. These relations allow us to predict missi…
