1. 6. Evaluation of Physics Informed Neural Networks in engineering simple structural analysis problems

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Georgios Nentidis; [2023]
   Keywords : ;

   Abstract : Neural Networks have found many applications for a long time in Machine Learning in different disciplines, and have especially flourished in the last decade because of the ever-increasing processing power especially from GPUs. Because of their ability to operate as universal function approximators and model nonlinear processes, attempts have been made in recent years to be also used for modeling partial differential equation (PDE) solutions.

3. 7. Elastic Net Regression for Prosthesis Control in Short Residual Limb Amputees: Performance and Generalizability

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Oskar Berg; [2023]
   Keywords : Neuroengineering; Statistics; Biomedical Signal Processing; Technology and Engineering;

   Abstract : This Master's thesis in Biomedical Engineering investigates the performance and generalizability of linear regression models in context of prosthesis control for short residual limb amputees. This thesis uses intramuscular electromyography data, and a regression and emplys a regression technique called Elastic Net Regression - a technique that combines L1 and L2-regularization - to predict 1-DOF isometric forces outputs from fingers and the wrist.

4. 8. LDPC DropConnect

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

   Author : Xi Chen; [2023]
   Keywords : Bayesian approach; Machine learning; Coding theory; Measurement uncertainty; Algorithms; Bayesiansk metod; Maskininlärning; Kodningsteori; Mätosäkerhet; Algoritmer;

   Abstract : Machine learning is a popular topic that has become a scientific research tool in many fields. Overfitting is a common challenge in machine learning, where the model fits the training data too well and performs poorly on new data. READ MORE

5. 9. Swedish Stock and Index Price Prediction Using Machine Learning

   University essay from Mälardalens universitet/Akademin för utbildning, kultur och kommunikation

   Author : Henrik Wik; [2023]
   Keywords : Stock Price Prediction; Machine Learning; Time Series Analysis; Linear Regression; K-Nearest Neighbors; Random Forest; Support Vector Machines; Neural Networks;

   Abstract : Machine learning is an area of computer science that only grows as time goes on, and there are applications in areas such as finance, biology, and computer vision. Some common applications are stock price prediction, data analysis of DNA expressions, and optical character recognition. READ MORE

6. 10. Computer-vision as an ErrorRecognition Tool for IndustryProduction Lines : A comparative study of models and neural networks

   University essay from Mittuniversitetet/Institutionen för data- och elektroteknik (2023-)

   Author : André Lundholm; [2023]
   Keywords : Computer-vision; Machine Learning; Wood Industry; Neural Network; Convolutional Neural Network; Anomaly Detection; Outlier Detection; Object Detection;

   Abstract : To use machine learning as a tool to help humans perform tasks is a common occurrence these days. Machine learning integration in the wood processing industry however, is more rare. Therefore it is suitable to research if machine learning works for some problem in this area. READ MORE
