6. Sentiment Classification of Amazon Product Reviews
Master-uppsats, Uppsala universitet/Statistiska institutionenSammanfattning : Opinions and attitudes expressed online contain information useful to companies and organizations. By using machine learning and statistical models automated ways of understanding online behavior can be implemented. LÄS MER
7. Sleep apnea prediction in a Swedish cohort : Can the STOP-Bang questionnaire be improved?
Magister-uppsats, Umeå universitet/StatistikSammanfattning : Obstructive sleep apnea (OSA) is defined as more than five breathing pauses per hour of sleep, an apnea-hypopnea index (AHI) > 5. STOP-Bang is a questionnaire that predicts the risk of sleep apnea based on risk factors, like snoring, hypertension, and throat circumference greater than 40 cm. LÄS MER
8. Classification of Repeated Measurement Data Using Growth Curves and Neural Networks
Master-uppsats, Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakultetenSammanfattning : This thesis focuses on statistical and machine learning methods designed for sequential and repeated measurement data. We start off by considering the classic general linear model (MANOVA) followed by its generalization, the growth curve model (GMANOVA), designed for analysis of repeated measurement data. LÄS MER
9. E-noses equipped with Artificial Intelligence Technology for diagnosis of dairy cattle disease in veterinary
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The main goal of this project, running at Neurofy AB, was that developing an AI recognition algorithm also known as, gas sensing algorithm or simply recognition algorithm, based on Artificial Intelligence (AI) technology, which would have the ability to detect or predict diary cattle diseases using odor signal data gathered, measured and provided by Gas Sensor Array (GSA) also known as, Electronic Nose or simply E-nose developed by the company. Two major challenges in this project were to first overcome the noises and errors in the odor signal data, as the E-nose is supposed to be used in an environment with difference conditions than laboratory, for instance, in a bail (A stall for milking cows) with varying humidity and temperatures, and second to find a proper feature extraction method appropriate for GSA.

10. Classification of a Sensor Signal Attained By Exposure to a Complex Gas Mixture
Master-uppsats, Linköpings universitet/Statistik och maskininlärningSammanfattning : 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. LÄS MER
