1. A Gradient Boosting Tree Approach for Behavioural Credit Scoring
University essay from KTH/Matematisk statistikAbstract : This report evaluates the possibility of using sequential learning in a material development setting to help predict material properties and speed up the development of new materials. To do this a Random forest model was built incorporating carefully calibrated prediction uncertainty estimates. READ MORE

2. A Comparative Analysis of Decision Tree Models in Identifying Landslide Susceptibility and Type Classification
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : Landslides pose a significant risk to human life and infrastructure, especially in Italy, which has a high frequency of landslide occurrences. To mitigate these hazards, Landslide Susceptibility Mapping (LSM) is crucial for identifying risk areas and developing appropriate mitigation strategies. READ MORE

3. Optimizing Load Balancing inRaytracing for Radio Frequency PropagationPredictive models developed for simulation systems
University essay from Uppsala universitet/Institutionen för informationsteknologiAbstract : This thesis presents two predictive models with the aim of pre-allocating memory efficiently in the Ericsson Radio Frequency Propagation Simulation System through the prediction model, so as to achieve the effect of load balancing. The proposed approaches utilize interpolation and the Gradient Boosting Decision Tree (GBDT) method from machine learning for prediction and apply both methods in multiple test scenarios. READ MORE

4. Evaluation of Machine Learning Classifiers for Refractory Epilepsy Classification
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Epilepsy is a neurological disease, where up to 40% of patients, known as having refractory epilepsy, do not become seizure-free through antiepileptic drugs (AEDs). Epilepsy surgery has the highest possibility of treating patients with refractory epilepsy, however, many are never referred to surgical evaluation. READ MORE

5. Modeling Melodic Accents in Jazz Solos
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : This thesis looks at how accurately one can model accents in jazz solos, more specifically the sound level. Further understanding the structure of jazz solos can give a way of pedagogically presenting differences within music styles and even between performers. Some studies have tried to model perceived accents in different music styles. READ MORE
