  3. 2. Preserving the Mental Map when Visualizing Dynamic Graphs : An Approach for Intermediate Representations in the C2 Java Compiler

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Emmy Yin; [2023]
    Keywords : Dynamic Graphs; Graph Layout Algorithms; Visualization; Hierarchical Graph Layouts; Dynamiska grafer; grafritningsalgoritmer; visualisering; hierarkiska grafritningar;

    Abstract : Graphs are powerful data structures that are widely used to represent complex forms of information. One area in which graphs are successfully being used is within compiler engineering, where a program under compilation can be represented as a graph that changes as the program is being compiled.

  4. 3. Control Barrier Functions for Formation Control of Leader-follower Multi-agent Systems

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Tianrun Sun; [2023]
    Keywords : Multi-agent System; Leader-follower System; Formation Control; Control Barrier Function; Connectivity Maintenance; Multi-agent-system; Leader-follower-system; Formations Kontroll; Kontroll Barriär Funktion; Underhåll av Anslutningsmöjligheter;

    Abstract : This thesis studies formation control for a class of general leader-follower multi-agent systems with Control Barrier Functions (CBFs) such that connectivity maintenance is fulfilled for all the neighboring agents. In leader-follower multi-agent systems, only the leader agents are controlled by the externally designed input, while the followers are guided through their dynamic couplings with the neighboring agents.

  5. 4. Breast Cancer Histological Grading Using Graph Convolutional Networks

    University essay from KTH/Matematik (Avd.)

    Author : Anton Normelius; [2022]
    Keywords : GCN; GraphSAGE; Breast cancer histological grading; GCN; GraphSAGE; Histologisk gradering av bröstcancer;

    Abstract : Technological advancements have opened up the possibility of digitizing the pathological landscape, enabling deep learning-based methods to analyze digitized tissue samples, i.e., whole slide images (WSIs). Attention has recently shifted toward modeling WSIs as graphs since graph representations can capture dynamic relationships. READ MORE

  6. 5. Reliable graph predictions : Conformal prediction for Graph Neural Networks

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Albin Bååw; [2022]
    Keywords : Conformal prediction; Graph Neural Networks; Dynamic graphs; Distribution shift; Coverage gap; Konform prediktion; Neurala Nätverk för Grafer; Dynamiska grafer; Distributionsförändring; täckningsgap;

    Abstract : We have seen a rapid increase in the development of deep learning algorithms in recent decades. However, while these algorithms have unlocked new business areas and led to great development in many fields, they are usually limited to Euclidean data. READ MORE
