1. Order in the random forest
Sammanfattning : In many domains, repeated measurements are systematically collected to obtain the characteristics of objects or situations that evolve over time or other logical orderings. Although the classification of such data series shares many similarities with traditional multidimensional classification, inducing accurate machine learning models using traditional algorithms are typically infeasible since the order of the values must be considered.

2. Studies in Efficient Discrete Algorithms
Sammanfattning : This thesis consists of five papers within the design and analysis of efficient algorithms.In the first paper, we consider the problem of computing all-pairs shortest paths in a directed graph with real weights assigned to vertices. We develop a combinatorial randomized algorithm that runs in subcubic time for a special class of graphs. LÄS MER
3. Finding, extracting and exploiting structure in text and hypertext
Sammanfattning : Data mining is a fast-developing field of study, using computations to either predict or describe large amounts of data. The increase in data produced each year goes hand in hand with this, requiring algorithms that are more and more efficient in order to find interesting information within a given time. LÄS MER
4. Dynamic Matrix Algorithms and Applications in Convex and Combinatorial Optimization
Sammanfattning : Dynamic algorithms are used to efficiently maintain solutions to problems where the input undergoes some changes.This thesis studies dynamic algorithms that maintain solutions to linear algebra problems and we explore their applications and implications for dynamic graphs and optimization problems.

5. INCREMENTAL FAULT DIAGNOSABILITY AND SECURITY/PRIVACY VERIFICATION
Sammanfattning : Dynamical systems can be classified into two groups. One group is continuoustime systems that describe the physical system behavior, and therefore are typically modeled by differential equations. The other group is discrete event systems (DES)s that represent the sequential and logical behavior of a system. LÄS MER
