  1. 1. Predictive Modeling and Statistical Inference for CTA returns : A Hidden Markov Approach with Sparse Logistic Regression

    University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

    Author : Oskar Fransson; [2023]
    Keywords : Probability theory; Statistical inference; finance; CTA; managed futures; machine learning; statistical learning; stochastic process; sparse logistic regression; Markov Chain Monte Carlo; Hidden Markov model;

    Abstract : This thesis focuses on predicting trends in Commodity Trading Advisors (CTAs), also known as trend-following hedge funds. The paper applies a Hidden Markov Model (HMM) for classifying trends. Additionally, by incorporating additional features, a regularized logistic regression model is used to enhance prediction capability. READ MORE

  3. 2. Trampoline jump classification using sparse data in machine learning

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

    Author : Fredrik Bitén; [2021]
    Keywords : ;

    Abstract : Within the last few years, machine learning has grown rapidly and become widely used when classifying data from inertial measurement units (IMU). Sensor data, and in particular accelerometer data, are used in different types of trick classifications for various sporting exercises. READ MORE

  4. 3. A mixed clinicopathological and molecular proxy of homologous recombination deficiency in triple negative breast cancer

    University essay from Lunds universitet/Examensarbeten i bioinformatik

    Author : Elise Walford; [2021]
    Keywords : Biology and Life Sciences;

    Abstract : Clinical models are increasingly employed in medical science as either diagnostic or prognostic aids. Machine-learning methods are able to draw links in large data that can be used to predict patient risk and allow more informed decisions regarding treatment and medication intervention. READ MORE

  5. 4. Diet, Emission and Diabetes : A treelet transform pattern analysis on Västerbotten Intervention Program

    University essay from Umeå universitet/Epidemiologi och global hälsa

    Author : Wossenseged Birhane Jemberie; [2018]
    Keywords : Treelet transform; Dietary patterns; Greenhouse gas emissions; Carbon footprint; dietary GHGE patterns; Diabetes; Dysglycemia; Västerbotten Intervention Program;

    Abstract : Objective: Researches which studied the relation of dietary greenhouse gas emissions with health outcomes are few, inconsistent and most of them are modelling studies which have not investigated empiric dietary emission patterns. In this study, we employ a posteriori data dimension reduction method, treelet transform, to identify dietary and diet related emission patterns concurrently. READ MORE

  6. 5. Automated Bug Report Routing

    University essay from Linköpings universitet/Statistik och maskininlärning

    Author : Caroline Svahn; [2017]
    Keywords : ;

    Abstract : As the software industry grows larger by the minute, the need for automated solutions within bug report management is on the rise. Although some research has been conducted in the area of bug handling, new, faster or more precise approaches are yet to be developed. READ MORE
