2. 1. Order in the random forest

   Author : Isak Karlsson; Henrik Boström; Lars Asker; Pierre Geurts; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Machine learning; random forest; ensemble; time series; data series; sequential data; sparse data; high-dimensional data; Computer and Systems Sciences; data- och systemvetenskap;

   Abstract : In many domains, repeated measurements are systematically collected to obtain the characteristics of objects or situations that evolve over time or other logical orderings. Although the classification of such data series shares many similarities with traditional multidimensional classification, inducing accurate machine learning models using traditional algorithms are typically infeasible since the order of the values must be considered.

4. 2. Nearest Neighbor Classification in High Dimensions

   Author : Sampath Deegalla; Henrik Boström; Slawomir Nowaczyk; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nearest Neighbor; High-Dimensional Data; Curse of Dimensionality; Dimensionality Reduction; data- och systemvetenskap; Computer and Systems Sciences;

   Abstract : The simple k nearest neighbor (kNN) method can be used to learn from high dimensional data such as images and microarrays without any modification to the original version of the algorithm. However, studies show that kNN's accuracy is often poor in high dimensions due to the curse of dimensionality; a large number of instances are required to maintain a given level of accuracy in high dimensions.

   Abstract : Mikroskopi är idag ett fundamentalt verktyg inom forskning, där det tillåter oss att skåda in och utforska våra prover i hög detalj. Mycket utav utvecklingen av nya mikroskopimetoder har strävat efter att öka den detaljnivå vi kan uppnå. READ MORE

6. 4. Secure and Privacy-aware Data Collection and Processing in Mobile Health Systems

   Author : Leonardo H Iwaya; Simone Fischer-Hübner; Leonardo Martucci; Rose-Mharie Åhlfeldt; Sokratis Katsikas; Karlstads universitet; []

   Abstract : Healthcare systems have assimilated information and communication technologies in order to improve the quality of healthcare and patient's experience at reduced costs. The increasing digitalization of people's health information raises however new threats regarding information security and privacy. READ MORE

7. 5. A path along deep learning for medical image analysis : With focus on burn wounds and brain tumors

   Author : Marco Domenico Cirillo; Anders Eklund; Veronika Cheplygina; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Deep learning; Medical image analysis; Burn wounds; Brain tumors; Image classification; Image segmentation; Image augmentation; CNNs; GANs;

   Abstract : The number of medical images that clinicians need to review on a daily basis has increased dramatically during the last decades. Since the number of clinicians has not increased as much, it is necessary to develop tools which can help doctors to work more efficiently. READ MORE
