  2. 16. Empirical Bayes Methods for DNA Microarray Data

    Author : Ingrid Lönnstedt; Allan Gut; Tom Britton; Mette Langaas; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematical statistics; two-channel microarrays; differential expression; replication; empirical Bayes; factorial design; interaction; time trends; hierarchical Bayes; MCMC simulations; ANOVA; F-statistics; Matematisk statistik; Mathematical statistics; Matematisk statistik;

    Abstract : cDNA microarrays is one of the first high-throughput gene expression technologies that has emerged within molecular biology for the purpose of functional genomics. cDNA microarrays compare the gene expression levels between cell samples, for thousands of genes simultaneously.

  4. 17. Guaranteeing Generalization via Measures of Information

    Author : Fredrik Hellström; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; PAC-Bayes; statistical learning; information theory; Machine learning; neural networks.; generalization;

    Abstract : During the past decade, machine learning techniques have achieved impressive results in a number of domains. Many of the success stories have made use of deep neural networks, a class of functions that boasts high complexity. Classical results that mathematically guarantee that a learning algorithm generalizes, i.e. READ MORE

  5. 18. Rainflow Analysis of Switching Markov Loads

    Author : Pär Johannesson; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; actuarial mathematics; programming; operations research; Statistics; rainflow matrix; fatigue; vehicle load; hidden Markov model; random load; Markov model; Switching process; Statistik; operationsanalys; programmering; aktuariematematik;

    Abstract : Rainflow cycles are often used in fatigue analysis of materials for describing the variability of applied loads. Therefore, an important characteristic of a random load process is the intensity of rainflow cycles, also called the expected rainflow matrix (RFM), which can be used for evaluation of the fatigue life.

  6. 19. Crossings and maxima in Gaussian fields and seas

    Author : Eva Sjö; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; operations research; Statistics; random waves; extremes; generalised Rice s formula; level-crossings; Gaussian random fields; programming; actuarial mathematics; Statistik; operationsanalys; programmering; aktuariematematik;

    Abstract : In this thesis the focus is on crossing points in random fields and the probability distributions of various crossing variables in different applications. The crossing points are generalisations to random fields of points of level crossings by stochastic processes. READ MORE

  7. 20. Modelling collective movement and transport network formation in living systems

    Author : Arianna Bottinelli; David Sumpter; Renaud Lambiotte; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; animal collective behaviour; transport networks; crowd dynamics; complex systems; ants; fish; Tillämpad matematik och statistik; Applied Mathematics and Statistics;

    Abstract : The emergence of collective patterns from repeated local interactions between individuals is a common feature to most living systems, spanning a variety of scales from cells to animals and humans. Subjects of this thesis are two aspects of emergent complexity in living systems: collective movement and transport network formation. READ MORE
