1. 21. Machine learning methods for seasonal allergic rhinitis studies

   University essay from Linköpings universitet/Statistik och maskininlärning

   Author : Zijie Feng; [2021]
   Keywords : Machine learning; Seasonal allergic rhinitis; Random forest; Partial least squares discriminant analysis; Bootstrap; Cubic smoothing splines; Single-cell RNA sequencing;

   Abstract : Seasonal allergic rhinitis (SAR) is a disease caused by allergens from both environmental and genetic factors. Some researchers have studied the SAR based on traditional genetic methodologies. As technology develops, a new technique called single-cell RNA sequencing (scRNA-seq) is developed, which can generate high-dimension data. READ MORE

3. 22. Bayes Factors for the Proposition of a Common Source of Amphetamine Seizures.

   University essay from Linköpings universitet/Statistik och maskininlärning

   Author : Yash Pawar; [2021]
   Keywords : Amphetamine Data; LDA; PLS-DA; NSC; Gaussaianize; pairwise ratios;

   Abstract : This thesis sets out to address the challenges with the comparison of Amphetamine material in determining whether they originate from the same source or different sources using pairwise ratios of peak areas within each chromatogram of material and then modeling the difference between the ratios for each comparison as a basis for evaluation. The evaluation of an existing method that uses these ratios to determine the sum of significant differences between each comparison of material that is provided is done. READ MORE

4. 23. NSGA-II DESIGN FOR FEATURE SELECTION IN EEG CLASSIFICATION RELATED TO MOTOR IMAGERY

   University essay from Mälardalens högskola/Akademin för innovation, design och teknik

   Author : Robin Johansson; [2020]
   Keywords : ;

   Abstract : Feature selection is an important step regarding Electroencephalogram (EEG) classification, for a Brain-Computer Interface (BCI) systems, related to Motor Imagery (MI), due to large amount of features, and few samples. This makes the classification process computationally expensive, and limits the BCI systems real-time applicability. READ MORE

5. 24. Feature Extraction and Classification of Medication-Induced Hyperkinesia During Treatment of Parkinson's Disease

   University essay from Lunds universitet/Matematisk statistik

   Author : Erik Liljeroth; [2020]
   Keywords : Parkinson s disease; neural network; autoencoder; classification; feature extraction; Mathematics and Statistics;

   Abstract : The recent progress in wearable sensor technology, signal processing and machine learning enables novel applications in fields such as automatic disease symptom tracking and classification. In this project, data from an ongoing Parkinson’s disease study at the Lund University Hospital is gathered and analyzed, and classification models of varying complexity for symptom severity are evaluated.

6. 25. Injector diagnosis based on engine angular velocity pulse pattern recognition

   University essay from Uppsala universitet/Signaler och system

   Author : David Nyman; [2020]
   Keywords : machine learning; supervised machine learning; neural network; internal combustion engine; fault diagnosis;

   Abstract : In a modern diesel engine, a fuel injector is a vital component. The injectors control the fuel dosing into the combustion chambers. The accuracy in the fuel dosing is very important as inaccuracies have negative effects on engine out emissions and the controllability. READ MORE
