  1. 1. Hierarchical Clustering of Time Series using Gaussian Mixture Models and Variational Autoencoders

    University essay from Lunds universitet/Matematisk statistik

    Author : Per Wilhelmsson; [2019]
    Keywords : Clustering; Deep Learning; Machine Learning; Time Series; Variational Autoencoders; Gaussian Mixture Models; Mathematics and Statistics;

    Abstract : This thesis proposes a hierarchical clustering algorithm for time series, comprised of a variational autoencoder to compress the series and a Gaussian mixture model to merge them into an appropriate cluster hierarchy. This approach is motivated by the autoencoders good results in dimensionality reduction tasks and by the likelihood framework given by the Gaussian mixture model. READ MORE

  2. 2. Demand Forecasting Of Outbound Logistics Using Machine learning

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Ashik Talupula; [2019]
    Keywords : Demand forecasting; Time series; Outbound logistics; Machine learning.;

    Abstract : Background: long term volume forecasting is important for logistics service providers for planning their capacity and taking the strategic decisions. At present demand is estimated by using traditional methods of averaging techniques or with their own experiences which often contain some error. READ MORE

  3. 3. Unsupervised anomaly detection in time series with recurrent neural networks

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

    Author : Josef Haddad; Carl Piehl; [2019]
    Keywords : ;

    Abstract : Artificial neural networks (ANN) have been successfully applied to a wide range of problems. However, most of the ANN-based models do not attempt to model the brain in detail, but there are still some models that do. An example of a biologically constrained ANN is Hierarchical Temporal Memory (HTM). READ MORE

  4. 4. A Comparison of Different Machine Learning Models for Cardiovascular Disease Detection

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

    Author : Aleksander Mitic; Oskar Nehlin; [2019]
    Keywords : ;

    Abstract : Cardiovascular disease (CVD) is the leading cause of death worldwide and the majority of the deaths occur in low to middle income countries. This makes the prevention of CVDs an accute problem to study and much research has been done already. READ MORE

  5. 5. Microarray Quality Control using Artificial Neural Networks

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik; Lunds universitet/Beräkningsbiologi och biologisk fysik

    Author : Emil Andersson; [2019]
    Keywords : Artificial Neural Network; ANN; Microarray; Quality Control; Automated Quality Control; Physics and Astronomy;

    Abstract : When using antibody microarrays to diagnose diseases, the process of quality control of the microarray data is an important step. Currently, a part of this process is performed manually by visual inspection. READ MORE
