  1. 1. Initial Development and Validation of Language-Based Assessments for Meaningful Change

    University essay from Lunds universitet/Institutionen för psykologi

    Author : Ulrika Söderström; [2024]
    Keywords : meaningful change; depression; Large Language Models; AI; Social Sciences;

    Abstract : Meaningful change has been discussed in multiple studies, with the recurring question of how it could be conceptualized and assessed to identify what determines meaningful change and where it occurs. Previous studies have conducted statistical analyses based on traditional rating scales (i.e., the PHQ-9) to assess meaningful change. READ MORE

  2. 2. Regularization Methods and High Dimensional Data: A Comparative Study Based on Frequentist and Bayesian Methods

    University essay from Lunds universitet/Statistiska institutionen

    Author : Markus Gerholm; Johan Sörstadius; [2024]
    Keywords : Linear regression; high dimensional data; regularization; Bayesian methods; Mathematics and Statistics;

    Abstract : As the amount of high dimensional data becomes increasingly accessible and common, the need for reliable methods to combat problems such as overfitting and multicollinearity increases. Models need to be able to manage large data sets where predictor variables often outnumber the amount of observations. READ MORE

  3. 3. Kernel Methods for Regression

    University essay from Linnéuniversitetet/Institutionen för matematik (MA)

    Author : Tom Lennart Rossmann; [2023]
    Keywords : Kernel Methods; Regression; Ridge Regression;

    Abstract : Kernel methods are a well-studied approach for addressing regression problems by implicitly mapping input variables into possibly infinite-dimensional feature spaces, particularly in cases where standard linear regression fails to capture non-linear relationships in data. Therefore, the choice between standard linear regression and kernel regression can be seen as a tradeoff between constraints on the number of features and the number of training samples. READ MORE

  4. 4. Regression with Bayesian Confidence Propagating Neural Networks

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

    Author : Raghav Rajendran Bongole; [2023]
    Keywords : Machine Learning; Neural Networks; Brain-like computing; Bayesian Confidence Propagating Neural Networks; Maskininlärning; neurala nätverk; hjärnliknande datorer; Bayesian Förtroendespridande neurala nätverk;

    Abstract : Bayesian Confidence Propagating Neural Networks (BCPNNs) are biologically inspired artificial neural networks. These networks have been modeled to account for brain-like aspects such as modular architecture, divisive normalization, sparse connectivity, and Hebbian learning. READ MORE

  5. 5. “When you see me, weep” : The archaeology of the hunger stones of Europe.

    University essay from Stockholms universitet/Arkeologi

    Author : Ivan Odbratt; [2023]
    Keywords : Hunger stones; Climate change; Memory; Archaeology;

    Abstract : This thesis investigates the phenomenon of hunger stones and their resurgence due to climate change-induced droughts, shedding light on their evolving societal significance. The initial focus lies on understanding the origins of the term and exploring how humanity has historically adapted to and remembered climatic transformations. READ MORE
