1. 16. Intelligent semi-structured information extraction : a user-driven approach to information extraction

   Författare :Anders Arpteg; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Artificiell intelligens; Informaitonsåtervinning; Artificial intelligence; Computer science; Datavetenskap;

   Sammanfattning : The number of domains and tasks where information extraction tools can be used needs to be increased. One way to reach this goal is to design user-driven information extraction systems where non-expert users are able to adapt them to new domains and tasks. LÄS MER

3. 17. Holistic Grasping: Affordances, Grasp Semantics, Task Constraints

   Författare :Martin Hjelm; Danica Kragic; Markus Vincze; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; robotics; robotic grasping; grasping; cognition; embodied cognition; computer vision; machine learning; artificial intelligence; AI; Gaussian process; Gaussian process latent variable model; GPLVM; 3D vision; point cloud features; robotik; manipulation; datorseende; maskininlärning; artificiell intelligens; kognition; Computer Science; Datalogi;

   Sammanfattning : Most of us perform grasping actions over a thousand times per day without giving it much consideration, be it from driving to drinking coffee. Learning robots the same ease when it comes to grasping has been a goal for the robotics research community for decades. LÄS MER

4. 18. Artificial neural networks classify myocardial perfusion images

   Författare :Dan Lindahl; Lund Klinisk fysiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tomography; radiology; Clinical physics; radionuclide imaging; ischemic heart disease; computer-assisted diagnosis; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

   Sammanfattning : In the studies of this thesis, a method for automated classification of myocardial perfusion images was successfully developed and evaluated. The results show that the method, based on artificial neural networks, was equally good, or even better than human experts. LÄS MER

5. 19. Topics on Large Deviations in Artificial Intelligence

   Författare :Adam Lindhe; Henrik Hult; Jimmy Olsson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical Statistics; Matematisk statistik;

   Sammanfattning : Artificial intelligence has become one of the most important fields of study during the last decade. Applications include medical sciences, autonomous vehicles, finance and everyday life. Therefore the analysis of convergence and stability of these algorithms is of utmost importance. LÄS MER

7. 20. A Study in the Computational Complexity of Temporal Reasoning

   Författare :Mathias Broxvall; Peter Jonsson; Ulf Nilsson; Anders Haraldsson; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; temporal and spatial information; artificiell intelligens; algebra; tractable fragments; temporal formalisms; formalism STP; Computer science; Datavetenskap;

   Sammanfattning : Reasoning about temporal and spatial information is a common task in computer science, especially in the field of artificial intelligence. The topic of this thesis is the study of such reasoning from a computational perspective. LÄS MER
