1. Evaluation of Machine Learning Classifiers for Refractory Epilepsy Classification
Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : 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. LÄS MER
2. Modeling Melodic Accents in Jazz Solos
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : 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. LÄS MER
3. Predicting IPO Underpricing: A study on the predictability of IPO underpricing through machine learning algorithms
C-uppsats, Handelshögskolan i Stockholm/Institutionen för redovisning och finansieringSammanfattning : This paper primarily serves to examine whether a specific subset of variables, derived from publicly available pre-IPO data, can be effectively modeled to predict and classify if an IPO will be underpriced using non-linear machine learning (ML) models. Secondly, we analyze whether the performance of ML-based models is greater compared to conventional linear models. LÄS MER
4. Maskininlärning med konform förutsägelse för prediktiva underhållsuppgifter i industri 4.0
Master-uppsats, Jönköping University/JTH, Avdelningen för datavetenskapSammanfattning : This thesis is a cooperation with Knowit, Östrand \& Hansen, and Orkla. It aimed to explore the application of Machine Learning and Deep Learning models with Conformal Prediction for a predictive maintenance situation at Orkla. Predictive maintenance is essential in numerous industrial manufacturing scenarios. LÄS MER
5. Prediction of Stock Returns Using Accounting Data with a Machine Learning Approach
Master-uppsats, Göteborgs universitet/Graduate SchoolSammanfattning : The relationship between accounting data and stock price prediction has been a hot topic for over half a century. Researchers have been trying to identify the relationship and investigate how it may be useful when trying to improve prediction accuracy. LÄS MER
