1. 11. Personalized Federated Learning for mmWave Beam Prediction Using Non-IID Sub-6 GHz Channels

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Yuan Cheng; [2022]
   Keywords : Personalized Federated Learning; Millimeter wave; Beamforming; DeepMIMO; Non-IID; Personaliserad Federad Inlärning; Millimetervågor; Strålformning; DeepMIMO; Icke-IID;

   Abstract : While it is difficult for base stations to estimate the millimeter wave (mmWave) channels and find the optimal mmWave beam for user equipments (UEs) quickly, the sub-6 GHz channels which are usually easier to obtain and more robust to blockages could be used to reduce the time before initial access and enhance the reliability of mmWave communication. Considering that the channel information is collected by a massive number of radio base stations and would be sensitive to privacy and security, Federated Learning (FL) is a match for this use case.

3. 12. Mortality Prediction in Intensive Care Units by Utilizing the MIMIC-IV Clinical Database

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Raymond Wang; [2022]
   Keywords : Clinical Data Science; Mortality Prediction; MIMIC-IV; Machine Learning; NLP; ICU;

   Abstract : Machine learning has the potential of significantly improving daily operations in health care institutions but many persistent barriers are to be faced in order to ensure its wider acceptance. Among such obstacles are the accuracy and reliability. READ MORE

4. 13. Prognostics for Condition Based Maintenance of Electrical Control Units Using On-Board Sensors and Machine Learning

   University essay from Linköpings universitet/Fordonssystem

   Author : Gabriel Fredriksson; [2022]
   Keywords : machine learning; random forest; random survival forest; condition based maintenance; cbm; reliability; solder joint failure; thermomechanical cycling; ECU; lifetime prediction; data-driven; statistics; BGA; PCBA; field quality; maintenance; truck; bus; vehicle;

   Abstract : In this thesis it has been studied how operational and workshop data can be used to improve the handling of field quality (FQ) issues for electronic units. This was done by analysing how failure rates can be predicted, how failure mechanisms can be detected and how data-based lifetime models could be developed. READ MORE

5. 14. Uncertainty quantification for neural network predictions

   University essay from Umeå universitet/Statistik

   Author : Jonas Borgström; [2022]
   Keywords : ;

   Abstract : Since their inception, machine learning methods have proven useful, and their usability continues to grow as new methods are introduced. However, as these methods are used for decision-making in most fields, such as weather forecasting,medicine, and stock market prediction, their reliability must be appropriately evaluated before the models are deployed.
