  1. 1. Sequential Anomaly Detection for Log Data Using Deep Learning

    University essay from Göteborgs universitet/Institutionen för matematiska vetenskaper

    Author : Lina Hammargren; Wei Wu; [2021-06-14]
    Keywords : anomaly detection; recurrent neural network; long short-term memory; semi-supervised learning; seq2seq; transformer; unsupervised learning; log analysis;

    Abstract : AbstractSoftware development with continuous integration changes needs frequent testing forassessment. Analyzing the test output manually is time-consuming and automatingthis process could be beneficial to an organization. READ MORE

  2. 2. Hierarchical Clustering To Improve Portfolio Tail Risk Characteristics

    University essay from Lunds universitet/Matematisk statistik

    Author : Adam Eidenvall; [2021]
    Keywords : Hierarchical Clustering; Asset Allocation; Portfolio Construction; Graph Theory; Machine Learning; Risk Parity; Regime Shift; Bootstrapping; Walk Forward; Mathematics and Statistics;

    Abstract : Many agree that estimating portfolio risks has better estimation possibilities, than estimations on returns. Therefore investors attempts to construct better, more efficient riskmanaged portfolios by diversifying portfolios through factors rather than traditional asset classes. READ MORE

  3. 3. Named-entity recognition with BERT for anonymization of medical records

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Olle Bridal; [2021]
    Keywords : NLP; anonymization; de-identification; NER; BERT; medical records; Swedish;

    Abstract : Sharing data is an important part of the progress of science in many fields. In the largely deep learning dominated field of natural language processing, textual resources are in high demand. In certain domains, such as that of medical records, the sharing of data is limited by ethical and legal restrictions and therefore requires anonymization. READ MORE

  4. 4. Identifying Machine States and Sensor Properties for a Digital Machine Template : Automatically recognize states in a machine using multivariate time series cluster analysis

    University essay from Mittuniversitetet/Institutionen för informationssystem och –teknologi

    Author : Jakob Viking; [2021]
    Keywords : Digital twin; Digital shadow; Unsupervised learning; Cluster analysis; HDBSCAN; Chi-squared goodness of fit test;

    Abstract : Digital twins have become a large part of new cyber-physical systems as they allow for the simulation of a physical object in the digital world. In addition to the new approaches of digital twins, machines have become more intelligent, allowing them to produce more data than ever before. READ MORE

  5. 5. Optimisation of autoencoders for prediction of SNPs determining phenotypes in wheat

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildningUppsala universitet/Institutionen för informationsteknologi

    Author : Karthik Nair; [2021]
    Keywords : Deep Learning; Machine Learning; Convolutional Neural Networks; Convolutional Variational Autoencoders; Autoencoders; SNP-Phenotype relationships; Genetics; Agricultural Bioinformatics; Neural Networks; Unsupervised Learning;

    Abstract : The increase in demand for food has resulted in increased demand for tools that help streamline plant breeding process in order to create new varieties of crops. Identifying the underlying genetic mechanism of favourable characteristics is essential in order to make the best breeding decisions. READ MORE
