  1. 16. The Effects of Low-Quality University Education on Young Graduated Labour Outcomes: The Peruvian Experience

    University essay from Lunds universitet/Ekonomisk-historiska institutionen

    Author : Adriana Cristina Raygada Mimbela; [2023]
    Keywords : quality of university education; graduated labour outcomes; Peruvian youth; National Survey of Households ENAHO ; Business and Economics; Social Sciences;

    Abstract : This thesis examines the relationship between university education quality and young graduates' labour outcomes. The thesis employs a micro-level data analysis based on the National Survey of Households (ENAHO) and information from the National Board of University Education (SUNEDU). READ MORE

  3. 17. Robustness Against Non-Normality : Evaluating LDA and QDA in Simulated Settings Using Multivariate Non-Normal Distributions

    University essay from Uppsala universitet/Statistiska institutionen

    Author : Gånheim Viktor; Åslund Isak; [2023]
    Keywords : Classification; Linear Discriminant Analysis; Quadratic Discriminant Analysis; Normality Assumption;

    Abstract : Evaluating classifiers in controlled settings is essential for empirical applications, as extensive knowledge on model-behaviour is needed for accurate predictions. This thesis investigates robustness against non-normality of two prominent classifiers, LDA and QDA. READ MORE

  4. 18. Finding Causal Relationships Among Metrics In A Cloud-Native Environment

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

    Author : Suresh Rishi Nandan; [2023]
    Keywords : Causality; Causal Discovery; Bayesian Network; Conditional Independence; Partial Correlation; Ensemble Causal Discovery; Anomaly Detection; Causal Graphs; Causality; Causal Discovery; Bayesian Network; Conditional Indeberoende; partiell korrelation; Ensemble Causal Discovery; Anomali Detektion; kausala grafer;

    Abstract : Automatic Root Cause Analysis (RCA) systems aim to streamline the process of identifying the underlying cause of software failures in complex cloud-native environments. These systems employ graph-like structures to represent causal relationships between different components of a software application. READ MORE

  5. 19. Scalable Nonparametric L1 Density Estimation via Sparse Subtree Partitioning

    University essay from Uppsala universitet/Statistik, AI och data science

    Author : Axel Sandstedt; [2023]
    Keywords : density estimation; scalable density estimation; nonparametric density estimation; scalable nonparametric density estimation; L1; L_1; anomaly detection; regression analysis;

    Abstract : We consider the construction of multivariate histogram estimators for any density f seeking to minimize its L1 distance to the true underlying density using arbitrarily large sample sizes. Theory for such estimators exist and the early stages of distributed implementations are available. READ MORE

  6. 20. Vibroacoustic Analysis of an OLTC Diverter Switch for Condition Monitoring : Time frequency analysis with Fourier and wavelet transform in combination with multivariate logistic regression for condition monitoring of OLTC diverter switch

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Simon Persson; [2023]
    Keywords : Wavelet transform; CWT; logistic regression; machine learning; ML; vibroacoustic analysis; time frequency analysis; tap changer; diverter switch; power transformer; classification; prediction; condition; vibrations; state prediction; Hitachi Energy;

    Abstract : Vibrations are everywhere around us all the time and we often recognise them as sounds that we can hear and analyse with our brain. In this thesis, data that has been gathered from a diverter switch (DS) in a controlled environment, is analysed. READ MORE
