  1. 1. Domain Knowledge and Representation Learning for Centroid Initialization in Text Clustering with k-Means : An exploratory study

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

    Författare :David Yu; [2023]
    Nyckelord :Natural language processing; Sentiment analysis; Clustering; Language model; Transformer; Heuristic; Språkteknologi; Sentimentanalys; Klustering; Språkmodell; Transformer; Heuristik;

    Sammanfattning : Text clustering is a problem where texts are partitioned into homogeneous clusters, such as partitioning them based on their sentiment value. Two techniques to address the problem are representation learning, in particular language representation models, and clustering algorithms. LÄS MER

  3. 2. Miljö och landskap : En undersökning av landskap och miljö i relation till placeringen avboplatser i Ystadområdet

    Kandidat-uppsats, Uppsala universitet/Arkeologi

    Författare :Rasmus Larshagen; [2023]
    Nyckelord :Predictive modeling; Maxent; Ystad area; Settlement patterns; Neolithic; Bronze age; Prediktiv modellering; Maxent; Ystadområdet; Bosättnings mönster; Neolitikum; Bronsålder;

    Sammanfattning : Denna studie undersöker relationen mellan landskap, miljö och placeringen av boplatser från neolitikum och bronsålder i Ystadområdet. Uppsatsen åstadkommer detta genom maximal entropi modellering av boplatsernas placering i relation till flera variabler i landskapet och miljön. LÄS MER

  4. 3. Exploring true random number generators Build on commercial-off-the-shelve Components

    M1-uppsats, Malmö universitet/Institutionen för datavetenskap och medieteknik (DVMT)

    Författare :Linnéa Mörk; [2023]
    Nyckelord :TRNG; RNG; Random number generator; commercial-off-the-shelve;

    Sammanfattning : Generating random numbers can be accomplished through various methods, with the primary distinction lying between pseudo-random number generators (PRNGs), which are commonly used for applications that require a large amount of random data, and true random number generators (TRNGs), which are commonly used for applications that need security and unpredictability. This thesis explores the feasibility of harnessing frequency variations in the electrical grid as a source of entropy for a TRNG. LÄS MER

  5. 4. Continuous Quantum Control of Quantum Dot Systems

    Master-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Daniel Holst; [2022]
    Nyckelord :Quantum Control; Quantum Fokker-Planck Master Equation; Maxwell s demon; Quantum dots; Full counting statistics; Generalized Quantum Measurements; Thermodynamics; Physics and Astronomy;

    Sammanfattning : Control and feedback operation of quantum systems have in recent years gained a lot of interest since they are fundamental to achieving functional quantum information processing systems but also of great importance in applications of information to energy conversion within quantum thermodynamics. This thesis has treated a new formalism for feedback control of quantum systems. LÄS MER

  7. 5. Explanation Methods for a Medical Image Classifier by Analysis of its Uncertainty

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

    Författare :Sanskar Gupta; [2022]
    Nyckelord :Uncertainty; Confidences; Calibration; Clustering; Multiclass classification;

    Sammanfattning : Over the last decade, neural networks have reached almost every field of science and technology. They have become a crucial part of various real-world applications, such as medical imaging. LÄS MER
