  2. 2. Principal Component Analysis and the Cross-Sectional Variation of Returns

    University essay from

    Author : Armin Ramovic; Mikael Åkerman; [2021-06-23]
    Keywords : Principal Component Analysis; PCA; principal components; cross-sectional variation of returns; risk premia; asset pricing; demensionality reduction; risk factors; machine learning;

    Abstract : We utilize Principal Component Analysis (PCA), a dimensionality reduction technique, on a set of 142 risk factors, including macroeconomic factors, proposed in financial literature to construct factor models with high explanatory powers when analysing the cross-sectional variation of portfolio returns. We apply a Fama and Macbeth (1973) two-pass regression to estimate risk premia commanded by our principal components. READ MORE

    Keywords : Classification; Random Forest; Linear Discriminant Analysis; Naive Bayes; Principal Component Analysis; Drift; Baseline Compensation; Normalization; Sensor; Signal Preprocessing.;

    Abstract : This thesis is carried out in collaboration with a private company, DANSiC AB This study is an extension of a research work started by DANSiC AB in 2019 to classify a source. This study is about classifying a source into two classes with the sensitivity of one source higher than the other as one source has greater importance. READ MORE

  4. 4. Temporal Multivariate Distribution Analysis of Cell Shape Descriptors

    University essay from Umeå universitet/Institutionen för fysik

    Author : Amanda Krantz; [2021]
    Keywords : ;

    Abstract : In early drug discovery and the study of the effects of new chemical compounds on cancer cells, the change in cell shape over time provides vital information about cell health. Live-cell image analysis systems can be used to extract cell-shape describing parameters of individual cells during exposure to new drugs. READ MORE

  5. 5. Venous Component Separation From a Pulse Oximeter Signal using Blind Source Separation with Ultrasound Imaging as Reference

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Björn Walter; Stefan Piiroinen; [2021]
    Keywords : Photoplethysmogram; PPG; Ultrasound; Blind Source Separation; PCA; SOBI; venous component; Technology and Engineering;

    Abstract : Intradialytic hypotension (IDH) is a major drawback of haemodialysis and occurs in more than every fifth dialysis treatment. There is a need for real-time measurement, with an ability to detect IDH before it occurs. Photoplethysmography (PPG) may provide sufficient information about hemodynamic status to prevent IDH.
