  1. 21. Imitation Learning on Branching Strategies for Branch and Bound Problems

    Master-uppsats, KTH/Matematisk statistik

    Författare :Magnus Axén; [2023]
    Nyckelord :Graph Networks; Convolutions; MIP; Branch and Bound; Facility Location Problem; MDP; Imitation Learning; Graf nätverk; Faltning; Blandade heltaltsproblem; Branch and Bound; Facility Location Problem; Markov; Imitationsinlärning;

    Sammanfattning : A new branch of machine and deep learning models has evolved in constrained optimization, specifically in mixed integer programming problems (MIP). These models draw inspiration from earlier solver methods, primarily the heuristic, branch and bound. LÄS MER

  3. 22. Analysis of simulated functional diversity in tropical forests: Differences between cultivated and naturally grown secondary forests in Cambodia

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Clarissa Graf; [2023]
    Nyckelord :physical geography; ecosystem analysis; functional diversity; plant functional traits; ecosystem modelling; secondary forest ecosystems; sustainable forest management; LPJ-GUESS; Earth and Environmental Sciences;

    Sammanfattning : Accelerated deforestation represents a major global environmental concern. Over the last decades Cambodia has experienced a drastic decrease in forest cover and measures to halt deforestation have not been as effective as planned. LÄS MER

  4. 23. Software Fault Detection in Telecom Networks using Bi-level Federated Graph Neural Networks

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Rémi Bourgerie; [2023]
    Nyckelord :5G 4G; Federated Learning; Graoh Learning; Graph-based Federated Learning; Temporal Graph Neural Networks; Time Series; Anomaly Detection; Fault Detection; 5G 4G; Federerat lärande; Graf lärande; Grafbaserat federerat lärande; Temporal Graph Neural Networks; Tidsserier; Upptäckt av anomalier; Upptäckt av fel;

    Sammanfattning : The increasing complexity of telecom networks, induced by the recent development of 5G, is a challenge for detecting faults in the telecom network. In addition to the structural complexity of telecommunication systems, data accessibility has become an issue both in terms of privacy and access cost. LÄS MER

  5. 24. Impact of Central Nodes in Information Propagation over Graphs

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Oskar Mellegård; [2023]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : There are many systems which can be represented as graphs, to say the least the networks in which we communicate with each other. Thorough understanding of graph structures enables better predictions of the dynamics in real life networks, such as the spreading of a disease in a community or failure propagation in a system.

  7. 25. Comparing Wrist Movement Analysis Technologies

    M1-uppsats, KTH/Hälsoinformatik och logistik

    Författare :Markus Hanna; Anton Cajander; [2023]
    Nyckelord :Work-Related Musculoskeletal Disorders; Depth Camera; Intel RealSense D435i; Inertial Measurement Unit; MediaPipe Hands; Hand Tracking; Arbetsrelaterade muskuloskeletala sjukdomar; Djupkamera; Intel RealSense D435i; Inertial Mätenhet; MediaPipe Hands; Handspårning;

    Sammanfattning : The wrist is a body part that can be used during repetitive movements in many work environments. There is a need to measure these movements in order to notice harmful repetitive movements in advance. There are many different ways to measure these movements, such as with the use of a depth camera. LÄS MER
