  1. 31. Offline and Online Models for Learning Pairwise Relations in Data

    Författare :Fazeleh Sadat Hoseini; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mulit-Armed Bandit; Pairwise Relations; Performance Modeling; Motion Trajectory Clustering; Minimax Distance; Bottleneck Identification; Online Learning; Representation Learning; Memory Efficiency; Concurrent Programming; Thompson Sampling;

    Sammanfattning : Pairwise relations between data points are essential for numerous machine learning algorithms. Many representation learning methods consider pairwise relations to identify the latent features and patterns in the data. This thesis, investigates learning of pairwise relations from two different perspectives: offline learning and online learning. LÄS MER

  5. 34. Creating and maintaining topologies in wireless networks

    Författare :Tomas Johansson; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dependable Communication and Computation Systems; Kommunikations- och beräkningssystem;

    Sammanfattning : Wireless ad-hoc networks differs in many aspects compared to traditional infrastructured networks. Among other things, individual nodes cannot be expected to know the topology of the entire network. LÄS MER

  7. 35. Data-Driven Techniques for Modeling and Analysis of User Behavior

    Författare :Christian Nordahl; Håkan Grahn; Marie Netz; Veselka Boeva; Blekinge Tekniska Högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Our society is becoming more digitalized for each day. Now, we are able to gather data from individual users with higher resolution than ever. With the increased amount of data on an individual user level, we can analyze their behavior. LÄS MER
