  2. 1. Governing the manifold subject : a praxiography of Swedish HIV treatment

    Author : Jeffrey A. Christensen; Peter Danholt; Linköpings universitet; []
    Keywords : HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Swedish HIV treatment; enactment; governing assemblages; the manifold subject; matters of accountability;

    Abstract : This thesis investigates a multiplicity of ways in which the subject of Swedish HIV treatment is enacted. Drawing on my own experiences of living with HIV in Sweden, the thesis articulates a concern with reflexive, performative, and normative dimensions of contemporary governing assemblages, research practices, and medical interventions.

  4. 2. Manifold Learning in Computational Biology

    Author : Jens Nilsson; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nonlinear Dimensionality Reduction; Gene Expression Data; Computational Biology; Machine Learning; Manifold Learning;

    Abstract : This thesis deals with manifold learning techniques and their application in gene expression data analysis. Manifold learning is the study of methods that aim to infer geometrical structure from data sampled from manifolds, enabling nonlinear solutions to various machine learning tasks. READ MORE

  5. 3. Manifold learning and representations for image analysis and visualization

    Author : Anders Brun; Hans Knutsson; Magnus Herberthson; Carl-Fredrik Westin; Reiner Lenz; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; manifold learning; image analysis; signal processing; diffusion tensor mri; Medical informatics; Medicinsk informatik;

    Abstract : We present a novel method for manifold learning, i.e. identification of the low-dimensional manifold-like structure present in a set of data points in a possibly high-dimensional space. The main idea is derived from the concept of Riemannian normal coordinates. READ MORE

  6. 4. Regression on Manifolds with Implications for System Identification

    Author : Henrik Ohlsson; Lennart Ljung; Jonas Mårtensson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System Identification; High-Dimensional Regression; Manifold; Gray-Box Identification.; Automatic control; Reglerteknik;

    Abstract : The trend today is to use many inexpensive sensors instead of a few expensive ones, since the same accuracy can generally be obtained by fusing several dependent measurements. It also follows that the robustness against failing sensors is improved. As a result, the need for high-dimensional regression techniques is increasing. READ MORE

  7. 5. Salient Region Detection Methods with Application to Traffic Sign Recognition from Street View Images

    Author : Keren Fu; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; normalized cut; traffic sign recognition; saliency propagation; color distribution; continuous conditional random field; manifold; Salient region detection; adaptive graph edge weights; color contrast; geodesics;

    Abstract : In the computer vision community, saliency detection refers to modeling the selective mechanism in human visual attentions. Outputs of saliency detection algorithms are called saliency maps, which represent conspicuousness levels of different scene areas. READ MORE
