1. Statistical Inference of Information in Networks : Causality and Directed Information Graphs
Sammanfattning : Over the last decades, the advancements in measurement, collection, and storage of data have provided tremendous amounts of information. Thus, it has become crucial to extract valuable features and analyze the characteristics of data. As we study more complex systems (e.g. LÄS MER
2. Structural Models of Network Contacts Between Actors Governed by Activity and Attraction
Sammanfattning : This thesis consists of five papers on the subject of statistical modeling of stochastic networks. The NG-model proposed in Paper I combines a block structure with parameters that capture the identities of vertices and thus the new approach stresses the concept of ego-nets, which describes the structure around identified vertices.

3. On Directed Random Graphs and Greedy Walks on Point Processes
Sammanfattning : This thesis consists of an introduction and five papers, of which two contribute to the theory of directed random graphs and three to the theory of greedy walks on point processes. We consider a directed random graph on a partially ordered vertex set, with an edge between any two comparable vertices present with probability p, independently of all other edges, and each edge is directed from the vertex with smaller label to the vertex with larger label.

4. Convergence to the Tracy-Widom distribution for longest paths in a directed random graph
Sammanfattning : .... LÄS MER
5. Exploiting Coherence in Voxelized Geometry
Sammanfattning : In computer graphics, the geometry of virtual worlds can be represented in numerousways, from collections of simple triangles or voxels to higher-order primitives likecurved surfaces. There is a trade-off, both in terms of memory consumption and processingtime, between the cost of an individual primitive and the number of primitivesrequired to faithfully represent the world.
