4. 3. Combining Register Data and X-Ray Images for a Precision Medicine Prediction Model of Thigh Bone Fractures

   Master-uppsats, Linköpings universitet/Institutionen för medicinsk teknik

   Författare :Alva Nilsson; Oliver Andlid; [2022]
   Nyckelord :AI; Machine Learning; Fusion; Classification; X-Ray Images; Register Data; EHR; Femoral Fractures; AFF; NFF; Transfer Learning;

   Sammanfattning : The purpose of this master thesis was to investigate if using both X-ray images and patient's register data could increase the performance of a neural network in discrimination of two types of fractures in the thigh bone, called atypical femoral fractures (AFF) and normal femoral fractures (NFF). We also examined and evaluated how the fusion of the two data types could be done and how different types of fusion affect the performance. LÄS MER

5. 4. Modification of the RusBoost algorithm : A comparison of classifiers on imbalanced data

   Magister-uppsats, Umeå universitet/Statistik

   Författare :Isak Forslund; [2022]
   Nyckelord :;

   Sammanfattning : In many situations data is imbalanced, meaning the proportion of one class is larger than the other(s). Standard classifiers often produce undesirable results when the data is imbalanced and different methods have been developed in the attempt to improve classification under such conditions. LÄS MER

7. 5. Deep Learning Semantic Segmentation of 3D Point Cloud Data from a Photon Counting LiDAR

   Master-uppsats, Linköpings universitet/Datorseende

   Författare :Caspian Süsskind; [2022]
   Nyckelord :Deep Learning; Machine Learning; Computer vision; Semantic Segmentation; Photon Counting LiDAR; LiDAR; Point Cloud; 3D Data; Point Cloud Segmentation; Point Classification; Convolutional Neural Network; CNN; SPVCNN; Djupinlärning; LiDAR; fotonräknande LiDAR; semantisk segmentering; datorseende; punktmoln; maskininlärning;

   Sammanfattning : Deep learning has shown to be successful on the task of semantic segmentation of three-dimensional (3D) point clouds, which has many interesting use cases in areas such as autonomous driving and defense applications. A common type of sensor used for collecting 3D point cloud data is Light Detection and Ranging (LiDAR) sensors. LÄS MER
