  1. 1. Topological regularization and relative latent representations

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

    Author : Alejandro García Castellanos; [2023]
    Keywords : Algebraic Topology; Large Language Models; Relative Representation; Representation Learning; Model Stitching; Topological DataAnalysis; Zero-shot; Algebraisk topologi; Stora språkmodeller; Relativ representation; Representationsinlärning; Modell sömmar; Topologisk dataanalys; Zero-shot;

    Abstract : This Master's Thesis delves into the application of topological regularization techniques and relative latent representations within the realm of zero-shot model stitching. Building upon the prior work of Moschella et al. READ MORE

  3. 2. Unauthorised Session Detection with RNN-LSTM Models and Topological Data Analysis

    University essay from KTH/Matematik (Avd.)

    Author : Nazar Maksymchuk Netterström; [2023]
    Keywords : Recurrent Neural Network; Long-Short-Term-Memory; Topological Data Analysis; Session based data; Anomaly detection; Time-series analysis; Imbalanced data; Master thesis; Neurala nätverk; Topologisk data analys; Detektion av avvikelse; Sessionsbaserad data; Tidserieanalys; Inbalancerad data; Masteruppsats;

    Abstract : This thesis explores the possibility of using session-based customers data from Svenska Handelsbanken AB to detect fraudulent sessions. Tools within Topological Data Analysis are employed to analyse customers behavior and examine topological properties such as homology and stable rank at the individual level. READ MORE

  4. 3. Probing Charm Production with Three-Particle Correlations in pp Collisions

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Author : Kim Haupt; [2023]
    Keywords : pp collisions; charm production; three-particle correlation; Pythia; Physics and Astronomy;

    Abstract : This thesis aims to investigate possible correlations between charm production and baryon production in proton-proton collisions through three-particle correlations. The question attempted to be answered is where, for a given charmed baryon, the balancing anti-charm particle and balancing anti-baryon are located. READ MORE

  5. 4. Electron-skyrmion systems, in and out of equilibrium, and isolated or contacted to reservoirs

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Emil Adam Jonatan Östberg; [2023]
    Keywords : skyrmion; skyrmions; NEGF; freen s function; quantum transport; non-equlibrium; topology; topological charge; skyrmionics; current induced; open system; Physics and Astronomy;

    Abstract : A Kondo lattice skyrmion model in contact with a macroscopic environment is simulated to explore skyrmion dynamics, which is an extension of previous work. The system is simulated using non-equilibrium Green's functions within the generalized Kadanoff-Baym ansatz and the wide band limit. READ MORE

  6. 5. Quantum Transport in Topological Insulator Nanowires

    University essay from KTH/Fysik

    Author : Sergi Pradas Rodriguez; [2023]
    Keywords : quantum transport; topological insulators; nanowires; numerical analysis; Kwant; etc.; kvanttransport; topologiska isolatorer; nanotrådar; numerisk analys; Kvant; etc.;

    Abstract : Three-dimensional topological insulators are materials that have a bulk band gap like a traditional insulator, but which hold topologically protected conducting surface states. In this thesis we present a numerical analysis of the surface states of topological insulator nanowires in the tight-binding approximation. READ MORE
