21. Predicting Airbnb Prices in European Cities Using Machine Learning
Kandidat-uppsats, Blekinge Tekniska Högskola/Fakulteten för datavetenskaperSammanfattning : Background: Machine learning is a field of computer science that focuses on creating models that can predict patterns and relations among data. In this thesis, we use machine learning to predict Airbnb prices in various European cities to help the hosts in setting reasonable prices for their properties. LÄS MER
22. Uncertainty Analysis : Severe Accident Scenario at a Nordic Nuclear Power Plant
Master-uppsats, Högskolan Dalarna/Institutionen för information och teknikSammanfattning : Nuclear Power Plants (NPP) undergo fault and sensitivity analysis with scenario modelling to predict catastrophic events, specifically releases of Cesium 137 (Cs-137). The purpose of this thesis is to find which of 108 input-features from Modular Accident Analysis Program (MAAP)simulation code are important, when there is large release of Cs-137 emissions. LÄS MER
23. Neural Networks for Modeling of Electrical Parameters and Losses in Electric Vehicle
Magister-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskapSammanfattning : Permanent magnet synchronous machines have various advantages and have showed the most superiorperformance for Electric Vehicles. However, modeling them is difficult because of their nonlinearity. LÄS MER
24. Evaluating Random Forest and k-Nearest Neighbour Algorithms on Real-Life Data Sets
Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Computers can be used to classify various types of data, for example to filter email messages, detect computer viruses, detect diseases, etc. This thesis explores two classification algorithms, random forest and k-nearest neighbour, to understand how accurately and how quickly they classify data.

25. Beyond the Big Five Factors: Using Facets and Nuances for Enhanced Prediction in Life Outcomes
Master-uppsats, Lunds universitet/Institutionen för psykologiSammanfattning : Objective: Previous research using personality traits to predict life outcomes has typically utilized the Big Five factors and, occasionally, their facets. However, recent research suggests that using items (reflecting personality nuances) can account for greater predictive variance. LÄS MER
