Propagation Kernels
Marion Neumann, Roman Garnett, Christian Bauckhage +1
We introduce propagation kernels, a general graph-kernel framework for efficiently measuring the similarity of structured data. Propagation kernels are based on monitoring how info…
A Note on Archetypal Analysis and the Approximation of Convex Hulls
Christian Bauckhage
We briefly review the basic ideas behind archetypal analysis for matrix factorization and discuss its behavior in approximating the convex hull of a data sample. We then ask how go…
Marginalizing over the PageRank Damping Factor
Christian Bauckhage
In this note, we show how to marginalize over the damping parameter of the PageRank equation so as to obtain a parameter-free version known as TotalRank. Our discussion is meant as…
A Comparison of Methods for Player Clustering via Behavioral Telemetry
Anders Drachen, Christian Thurau, Rafet Sifa +1
The analysis of user behavior in digital games has been aided by the introduction of user telemetry in game development, which provides unprecedented access to quantitative data on…
Strong Regularities in Growth and Decline of Popularity of Social Media Services
Christian Bauckhage, Kristian Kersting
We analyze general trends and pattern in time series that characterize the dynamics of collective attention to social media services and Web-based businesses. Our study is based on…
Characterizations and Kullback-Leibler Divergence of Gompertz Distributions
Christian Bauckhage
In this note, we characterize the Gompertz distribution in terms of extreme value distributions and point out that it implicitly models the interplay of two antagonistic growth pro…
Computing the Kullback-Leibler Divergence between two Generalized Gamma Distributions
Christian Bauckhage
We derive a closed form solution for the Kullback-Leibler divergence between two generalized gamma distributions. These notes are meant as a reference and provide a guided tour tow…
