1. 1. Efficient Image Retrieval with Statistical Color Descriptors

   Författare :Linh Viet Tran; Reiner Lenz; Björn Kruse; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; color properties; images; statistical; content-based image retrieval CBIR ; non-parametric density estimators; image database; Kernel; Gram-Schmidt; geometry-based; Information technology; Informationsteknologi;

   Sammanfattning : Color has been widely used in content-based image retrieval (CBIR) applications. In such applications the color properties of an image are usually characterized by the probability distribution of the colors in the image. LÄS MER

3. 2. Statistical Inference of Information in Networks : Causality and Directed Information Graphs

   Författare :Sina Molavipour; Mikael Skoglund; Deniz Gündüz; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Over the last decades, the advancements in measurement, collection, and storage of data have provided tremendous amounts of information. Thus, it has become crucial to extract valuable features and analyze the characteristics of data. As we study more complex systems (e.g. LÄS MER

4. 3. Information-Theoretic Generalization Bounds: Tightness and Expressiveness

   Författare :Fredrik Hellström; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; information theory; neural networks; generalization; statistical learning; meta learning; PAC-Bayes; Machine learning;

   Sammanfattning : Machine learning has achieved impressive feats in numerous domains, largely driven by the emergence of deep neural networks. Due to the high complexity of these models, classical bounds on the generalization error---that is, the difference between training and test performance---fail to explain this success. LÄS MER

5. 4. Assessment of Enterprise Information Security : How to make it Credible and Efficient

   Författare :Erik Johansson; Torsten Cegrell; Rune Gustavsson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Enterprise Information Security; Enterprise Architecture; Security Assessment; Information Technology Management; Information technology; Informationsteknik;

   Sammanfattning : Information is an important business asset in today’s enterprises. Hence enterprise information security is an important system quality that must be carefully managed. LÄS MER

7. 5. Analyzing real-world data to promote development of active safety systems that reduce car-to-vulnerable road user accidents

   Författare :Azra Habibovic; Chalmers tekniska högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Accident prevention; Naturalistic observation; Causation analysis; Active safety system; Vulnerable road user VRU ; Driver behavior; Functional requirements; Statistical analysis; VRU behavior;

   Sammanfattning : The overall objective of the thesis is to explore various types of real-world road traffic data and to assess the extent to which they can inform the design of active safety systems that aim to prevent car-to-vulnerable road user (VRU) accidents. A combined analysis of in-depth and police reported accident data provided information on driver behavior and contextual variables, which is valuable for the development of active safety systems.
