  1. 1. Regularization for Sparseness and Smoothness : Applications in System Identification and Signal Processing

    Författare :Henrik Ohlsson; Lennart Ljung; Jacob Roll; Bo Wahlberg; Linköpings universitet; []
    Nyckelord :Regularization; sparsity; smothness; lasso; l1; fMRI; bio-feedback; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : In system identification, the Akaike Information Criterion (AIC) is a well known method to balance the model fit against model complexity. Regularization here acts as a price on model complexity. LÄS MER

  3. 2. Higher-Order Regularization in Computer Vision

    Författare :Johannes Ulén; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computer Vision; Regularization; Segmentation; Dense Stereo;

    Sammanfattning : At the core of many computer vision models lies the minimization of an objective function consisting of a sum of functions with few arguments. The order of the objective function is defined as the highest number of arguments of any summand. LÄS MER

  4. 3. Regularization of Parameter Problems for Dynamic Beam Models

    Författare :Sara Rydström; Börje Nilsson; Fredrik Berntsson; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Euler-Bernoulli beam equation; parameter identification; bending stiffness; refractive index; Tikhonov regularization; Applied mathematics; Tillämpad matematik; Mathematics; Matematik;

    Sammanfattning : The field of inverse problems is an area in applied mathematics that is of great importance in several scientific and industrial applications. Since an inverse problem is typically founded on non-linear and ill-posed models it is a very difficult problem to solve. LÄS MER

  5. 4. Resettling Displaced Residents from Regularized Settlements in Dar es Salaam City, Tanzania : The case of Community Infrastructure Upgrading Program (CIUP)

    Författare :Dawah Lulu Magembe-Mushi; Inga Britt Werner; John Lupala; Kristina Nilsson; KTH; []
    Nyckelord :Regularization; upgrading; displaced residents; informal settlements; resettlement; displacement; Dar es Salaam; Tanzania;

    Sammanfattning : This research seeks to examine the process of displacement and resettlement of residents who had been affected by regularization process within Manzese and Buguruni wards in Dar es Salaam City, Tanzania. It aimed at analyzing the issues and opportunities faced by the affected residents during regularization. LÄS MER

  7. 5. Algorithms for a Partially Regularized Least Squares Problem

    Författare :Ingegerd Skoglund; Tommy Elfving; Inge Söderkvist; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Least squares; Regularization; Block-matrices; Conjugate gradient; QR-factorization; Cross-validation; Numerical analysis; Numerisk analys;

    Sammanfattning : Vid analys av vattenprover tagna från t.ex. ett vattendrag betäms halten av olika ämnen. Dessa halter är ofta beroende av vattenföringen. LÄS MER
