  1. 16. Tame representations in Topological Data Analysis: decompositions, invariants and metrics

    Författare :Francesca Tombari; Wojciech Chachólski; Patrizio Frosini; Peter Bubenik; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; topological data analysis; tameness; decompositions; invariants; metrics; Matematik; Mathematics;

    Sammanfattning : This thesis is a compilation of results that can be framed within the field of applied topology. The starting point of our study is objects presenting a possibly complex intrinsic geometry. The main goal is then to simplify, without trivializing, the geometric information characterising these objects by choosing an appropriate representation.

  3. 17. Statistical Feature Selection : With Applications in Life Science

    Författare :Roland Nilsson; Jesper Tegnér; Johan Björkegren; Sepp Hochreiter; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Machine learning; supervised learning; classification; dimemsionality reduction; multiple testing; gene expression; microarray; cancer; Bioinformatics; Bioinformatik;

    Sammanfattning : The sequencing of the human genome has changed life science research in many ways. Novel measurement technologies such as microarray expression analysis, genome-wide SNP typing and mass spectrometry are now producing experimental data of extremely high dimensions. LÄS MER

  4. 18. Generalized General Logics

    Författare :Robert Helgesson; Patrik Eklund; Andrzej Tarlecki; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datalogi;

    Sammanfattning : Logic as a vehicle for sound reason has a long and lustrous history and while most developments follow the traditional notions of binary truth and crisp sentences, great efforts have been placed into the problem of reasoning with uncertainties. To this end the field of "fuzzy logic" is now of great importance both theoretically and practically. LÄS MER

  5. 19. Be My Guest: Normalizing and Compiling Programs using a Host Language

    Författare :Nachiappan Valliappan; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; programming languages; embedded domain-specific languages; normalization by evaluation;

    Sammanfattning : In programming language research, normalization is a process of fundamental importance to the theory of computing and reasoning about programs. In practice, on the other hand, compilation is a process that transforms programs in a language to machine code, and thus makes the programming language a usable one. LÄS MER

  7. 20. Modular Normalization with Types

    Författare :Nachiappan Valliappan; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Programming Languages; Functional Programming;

    Sammanfattning : With the increasing use of software in today’s digital world, software is becoming more and more complex and the cost of developing and maintaining software has skyrocketed. It has become pressing to develop software using effective tools that reduce this cost. LÄS MER
