1. 1. Integrating web data miningand machine learningalgorithms to predict progression free survival and overall survival in multiple myeloma patients

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Yijie Zhou; [2023]
   Keywords : ;

   Abstract : Multiple myeloma patients have highly variable progression free survival and overall survivalranging from a few weeks to more than 5 years. Stratification of these patients can help toidentify high risk patients i-e patients with short-term progression free survival and overallsurvival. READ MORE

3. 2. Perron-Frobenius' Theory and Applications

   University essay from Linköpings universitet/Algebra, geometri och diskret matematik; Linköpings universitet/Tekniska fakulteten

   Author : Karl Eriksson; [2023]
   Keywords : Positive matrices; nonnegative matrices; Perron-Frobenius; linear dynamical systems; Leslie matrices; Markov chain; Google s PageRank algorithm; Positiva matriser; icke-negativa matriser; Perron-Frobenius; linjära dynamiska system; Leslie matris; Markov-kedja; Google s PageRank algoritm;

   Abstract : This is a literature study, in linear algebra, about positive and nonnegative matrices and their special properties. We say that a matrix or a vector is positive/nonnegative if all of its entries are positive/nonnegative. First, we study some generalities and become acquainted with two types of nonnegative matrices; irreducible and reducible. READ MORE

4. 3. Damping Factor Analysis for PageRank

   University essay from Mälardalens universitet/Akademin för utbildning, kultur och kommunikation

   Author : Fredrik Scheie; [2022]
   Keywords : PageRank; Damping factor; Probability matrix; Google matrix;

   Abstract : The purpose of this thesis is to present research related to the damping factor in relation to the PageRank algorithm where a method of symbolic calculations is used to calculate eigenvalues, eigenvectors corresponding to the Google matrix in relation to both directed and undirected graphs. These graphs given comprise all the directed graphs up to four vertices and in addition the undirected graphs of five vertices are given in this thesis. READ MORE

5. 4. Invasive species in Weddell Sea : Effects on food web structure

   University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

   Author : Inger-Marie Wohlfarth; [2020]
   Keywords : Centrality; Climate change; Food webs; Google PageRank; Invasive species; Structure; Weddell Sea;

   Abstract : The cold water of Antarctica has a unique endemic fauna, where durophagous predators are rare or absent. Due to climate change the water is heating up and the predators have begun to return to the Southern Ocean, which could bring a lot of changes to the food web. There is a high risk it will lead to losses in the unique marine fauna of Antarctica. READ MORE

6. 5. A comparison of a Lazy PageRank and variants for common graph structures

   University essay from Mälardalens högskola/Akademin för utbildning, kultur och kommunikation

   Author : Barkat Aziz Ali; [2018]
   Keywords : Lazy PageRank; graph structures;

   Abstract : The thesis first reviews the mathematics behind the Google’s PageRank, which is the state-of-the-art webpage ranking algorithm. The main focus of the thesis is on exploring a lazy PageRank and variants, related to a random walk, and by realizing that, they can be computed using the very same algorithm, find lazy PageRank and variants' expressions for some common graph structures, for example, a line-graph, a complete-graph, a complete-bipartite graph including a star graph, and try to get some understanding of the behavior of the PageRank, when a network evolves, for example either by a contraction or an expansion of graphs’ nodes or links.
