  1. 21. A study about Active Semi-Supervised Learning for Generative Models

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Elisio Fernandes de Almeida Quintino; [2023]
    Keywords : Semi-Supervised Learning; Active Learning; Generative Models; Mixture Models; Semi-Övervakad Inlärning; Aktiv Inlärning; Generativa Modeller; Mixturmodeller;

    Abstract : In many relevant scenarios, there is an imbalance between abundant unlabeled data and scarce labeled data to train predictive models. Semi-Supervised Learning and Active Learning are two distinct approaches to deal with this issue. READ MORE

  3. 22. Statistics of Electric and Magnetic Fields at the Earth’s Bow Shock

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

    Author : Tsz-Kiu Wong-Chan; [2023]
    Keywords : MMS; Earth’s bow shock; Collisionless shocks; Correlation study; statistics; Space; Space plasma physics; MMS; Jordens bogchock; Kollisionsfria chocker; Korrelationsstudie; Statistik; Rymd; Rymdplasmafysik;

    Abstract : The interaction between the solar wind and Earth’s magnetic field creates the Earth’s bow shock. It is an ideal region for space probes like MMS, THEMIS or Clusters to study the collisionless shock phenomenon in space plasma. READ MORE

  4. 23. Characterizing, classifying and transforming language model distributions

    University essay from Uppsala universitet/Institutionen för lingvistik och filologi

    Author : Annika Kniele; [2023]
    Keywords : Large Language Models LLMs ; GPT; BERT; NLP; deep learning; machine learning; computational linguistics; language technology;

    Abstract : Large Language Models (LLMs) have become ever larger in recent years, typically demonstrating improved performance as the number of parameters increases. This thesis investigates how the probability distributions output by language models differ depending on the size of the model. READ MORE

  5. 24. The Magnetocaloric Effect in Antiferromagnetic and Noncollinear Magnets

    University essay from Uppsala universitet/Materialteori

    Author : Siri Alva Berge; [2023]
    Keywords : magnetocaloric effect; atomistic spin dynamics; monte carlo; antiferromagnet; neodymium; noncollinear magnetism;

    Abstract : The magnetocaloric effect (MCE) is the temperature change in a magnetic material due to a change in an applied magnetic field. How the MCE behaves in different magnetic materials and at different phase transitions is fundamental to understand. READ MORE

  6. 25. Towards algorithmic theory construction in physics

    University essay from Stockholms universitet/Fysikum

    Author : Hampus Möller; [2023]
    Keywords : Symbolic regression; machine learning; symmetry; minimum description length; entropy;

    Abstract : This master thesis explores the challenge of algorithmic hypothesis generation and its connection to potential inductive biases. In the scientific method, hypotheses are formulated and tested against data for validity. The process of hypothesis generation is, however, not explicitly formulated. READ MORE
