  3. 22. Evaluation of the Robustness of Different Classifiers under Low- and High-Dimensional Settings

    University essay from Uppsala universitet/Statistiska institutionen

    Author : Linnea Lantz; [2019]
    Keywords : LDA; QDA; DLDA; DQDA; GQDA;

    Abstract : This thesis compares the performance and robustness of five different varities of discriminant analysis, namely linear (LDA), quadratic (QDA), generalized quadratic (GQDA), diagonal linear (DLDA) and diagonal quadratic (DQDA) discriminant analysis, under elliptical distributions and small sample sizes.  By means of simulations, the performance of the classifiers are compared against separation of mean vectors, sample size, number of variables, degree of non-normality and covariance structures.

  4. 23. Linear Discriminant Analysis with Repeated Measurements

    University essay from Linköpings universitet/Matematisk statistik

    Author : Evelina Skinner; [2019]
    Keywords : Classification; repeated measurements; linear discriminant analysis; the Growth Curve model; missing data; classification robustness; additional measurements;

    Abstract : The classification of observations based on repeated measurements performed on the same subject over a given period of time or under different conditions is a common procedure in many disciplines such as medicine, psychology and environmental studies. In this thesis repeated measurements follow the Growth Curve model and are classified using linear discriminant analysis. READ MORE

  5. 24. Evaluation of a Radiomics Model for Classification of Lung Nodules

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Parastu Rahgozar; [2019]
    Keywords : Lung Nodule; Radiomics; Tumor Classification;

    Abstract : Lung cancer has been a major cause of death among types of cancers in the world. In the early stages, lung nodules can be detected by the aid of imaging modalities such as Computed Tomography (CT). In this stage, radiologists look for irregular rounded-shaped nodules in the lung which are normally less than 3 centimeters in diameter. READ MORE
