1. 1. Exploring Automated Early Problem Identification Based on Diagnostic Trouble Codes

   University essay from Institutionen för tillämpad informationsteknologi

   Author : Mathias Forsman; Yihan Yang; [2024-03-05]
   Keywords : Automotive Industry; Early Problem Identification; Diagnostic Trouble Code; Case Study; Laboratory Experiment ; Machine Learning; Linear Regression; K-means Clustering;

   Abstract : In the current automotive industry, problem identification is a reactive process. It starts when the customer experiences a vehicle problem and goes to the workshop. Subsequently, all the problem-related data will be collected from the workshop and forwarded to the vehicle manufacturer. READ MORE

3. 2. Vertical movement asymmetries in 3-year-old SWB horses and their associations with scores in Young Horse Tests

   University essay from SLU/Dept. of Anatomy, Physiology and Biochemistry

   Author : Anna Kallings Larsson; [2024]
   Keywords : orthopaedic health; objective gait assessment; conformation; linear profiling; movement asymmetry; artificial intelligence; computer vision; Swedish Warmblood;

   Abstract : To improve equine performance and welfare, many attempts have been made to investigate associations between performance, longevity, orthopaedic health, conformation and talent. Causal relationships between these qualities supported by strong scientific evidence are lacking. READ MORE

4. 3. Robust Portfolio Optimization with Correlation Penalties

   University essay from KTH/Matematisk statistik

   Author : Pelle Nydahl; [2023]
   Keywords : Portfolio Optimization; Portfolio Allocation; Robust Optimization; Correlation; Risk Factor Model; EMA Filtering; Weighted Linear Regression; Portföljoptimering; Portföljallokering; Robust optimering; Korrelation; Riskfaktor-modell; EMA-filtrering; Viktad linjär regression;

   Abstract : Robust portfolio optimization models attempt to address the standard optimization method's high sensitivity to noise in the parameter estimates, by taking an investor's uncertainty about the estimates into account when finding an optimal portfolio. In this thesis, we study robust variations of an extension of the mean-variance problem, where an additional term penalizing the portfolio's correlation with an exogenous return sequence is included in the objective.
