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

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

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

    Abstract : 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. READ MORE

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

    University essay from Malmö universitet/Institutionen för datavetenskap och medieteknik (DVMT)

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

    Abstract : 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. READ MORE

  4. 3. Continuous Quantum Control of Quantum Dot Systems

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

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

    Abstract : 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. READ MORE

    Author : Sanskar Gupta; [2022]
    Keywords : Uncertainty; Confidences; Calibration; Clustering; Multiclass classification;

    Abstract : 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. READ MORE

  6. 5. Polar Codes for Biometric Identification Systems

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

    Author : Yicheng Bao; [2022]
    Keywords : Biometrics; Polar codes; Identification systems; Convolutional neural networks; Autoencoder; Privacy preservation; Biometri; Polära koder; Identifieringssystem; Konvolutionella neurala nätverk; Autoencoder; Sekretessskydd;

    Abstract : Biometrics are widely used in identification systems, such as face, fingerprint, iris, etc. Polar code is the only code that can be strictly proved to achieve channel capacity, and it has been proved to be optimal for channel and source coding. READ MORE
