  1. 1. Improving Community Detection Methods for Network Data Analysis

    Författare :Farnaz Moradi; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Spam; Overlapping Communities; Networks; Misbehavior Detection; Seed Selection; Community Detection Algorithms; Medical Query Logs;

    Sammanfattning : Empirical analysis of network data has been widely conducted for understanding and predicting the structure and function of real systems and identifying interesting patterns and anomalies. One of the most widely studied structural properties of networks is their community structure. LÄS MER

  3. 2. Graph-based Analytics for Decentralized Online Social Networks

    Författare :Amira Soliman; Sarunas Girdzijauskas; Eiko Yoneki; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Decentralized Community Detection; Community-aware Learning; Spam Detection; Identity Validation; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : Decentralized Online Social Networks (DOSNs) have been introduced as a privacy preserving alternative to the existing online social networks.  DOSNs remove the dependency on a centralized provider and operate as distributed information management platforms. LÄS MER

  4. 3. Towards Understanding the Social Structure of Email and Spam Traffic

    Författare :Farnaz Moradi; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Internet Backbone Traffic; Email Networks; Spam; Social Network Analysis; Community Detection; Anomaly Detection;

    Sammanfattning : Email is a pervasive means of communication on the Internet. Email exchanges between individuals can be seen as social interactions between email sender(s) and receiver(s), thus can be represented as a network. LÄS MER

  5. 4. Salient Region Detection Methods with Application to Traffic Sign Recognition from Street View Images

    Författare :Keren Fu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; normalized cut; traffic sign recognition; saliency propagation; color distribution; continuous conditional random field; manifold; Salient region detection; adaptive graph edge weights; color contrast; geodesics;

    Sammanfattning : In the computer vision community, saliency detection refers to modeling the selective mechanism in human visual attentions. Outputs of saliency detection algorithms are called saliency maps, which represent conspicuousness levels of different scene areas. LÄS MER

  7. 5. Mobile robot fault detection using multiple localization modules

    Författare :Paul Sundvall; Bo Wahlberg; Patric Jensfelt; Fredrik Gustafsson; KTH; []
    Nyckelord :;

    Sammanfattning : Most applications in service robotics require that the position of the robot is accurately known. Faults affecting the localization system can thus have serious effects on the overall performance. LÄS MER
