  1. 1. Feature Selection for Microarray Data via Stochastic Approximation

    Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Erik Rosvall; [2024-03-18]
    Nyckelord :feature selection; feature ranking; microarray data; stochastic approximation; Barzilai and Borwein method; Machine Learning; AI;

    Sammanfattning : This thesis explores the challenge of feature selection (FS) in machine learning, which involves reducing the dimensionality of data. The selection of a relevant subset of features from a larger pool has demonstrated its effectiveness in enhancing the performance of various machine learning algorithms. LÄS MER

  3. 2. Adapted data collection in field utilizing RMR and the Q-system

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Amanda Olsson; [2024]
    Nyckelord :Rock mass classification; Q-slope; SMR; Slope stability;

    Sammanfattning : The focus on slope stability has increased rapidly in Norway over the last years due to several unwanted landslides. In Norway, the most used method today to classify the rock mass and to determine the required reinforcement, is the Q-system. In addition to that the RMR method is also a commonly used method.

  4. 3. Predictive Modeling of Pipetting Dynamics. Multivariate Regression Analysis: PLS and ANN for Estimating Density and Volume from Pressure Recordings

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Lisa Linard Pedersen; [2024]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Thermo Fisher Scientific manufacture automatic pipetting instruments for diagnostic tests. These tests are sensitive to abnormalities and changes in e.g. volume or density could potentially lead to less precision or other issues in the pipetting work flow. LÄS MER

  5. 4. The association between obesity, low-grade inflammation, self-reported knee symptoms and radiographic knee osteoarthritis in individuals with knee pain : A longitudinal cohort study

    Magister-uppsats, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Författare :Alma Buer; [2024]
    Nyckelord :osteoarthritis knee pain; artros knä smärta;

    Sammanfattning : Abstract  Background One of the earliest signs of knee osteoarthritis (OA) is knee pain which correlates with inflammation and disease severity. Knee OA affects 260 million worldwide, and is in similarity with obesity, characterized by ongoing low-grade inflammation. LÄS MER

  7. 5. UPPLEVD TRYGGHET I EN TID AV ESKALERAT SKJUTVAPENVÅLD : En kvantitativ studie över betydelsen av storstadsområden och sociodemografiska egenskaper

    Kandidat-uppsats, Umeå universitet/Sociologiska institutionen

    Författare :Emelie Jäderberg; Maja Palm; [2024]
    Nyckelord :gang violence; gun violence; metropolitan areas; perceived security; shootings; socio-demographics;

    Sammanfattning : Gun violence has increased significantly in Sweden in the past years. The purpose of this study is therefore to investigate whether the number of shootings has an impact on the residents' sense of perceived security in Sweden's metropolitan areas, with the control variables of the socio-demographic characteristics gender, age and education level.
