  1. 1. Swedish Interest Rate Curve Dynamics Using Artificial Neural Networks

    University essay from KTH/Matematisk statistik; KTH/Matematisk statistik

    Author : Richard Spånberg; Billy Wallander; [2020]
    Keywords : Artificial Neural Network; Yield curve; PCA; Financial Mathematics; Neurala Nätverk; Avkastningskurva; PCA; Finansiell Matematik;

    Abstract : This thesis is a comparative study where the question is whether a neural network approach can outperform the principal component analysis (PCA) approach for predicting changes of interest rate curves. Today PCA is the industry standard model for predicting interest rate curves. READ MORE

  2. 2. Training Bayesian Neural Networks

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik

    Author : Johan Book; [2020]
    Keywords : artificial neural networks; ANN; convolutional neural networks; Physics and Astronomy;

    Abstract : Although deep learning has made advances in a plethora of fields, ranging from financial analysis to image classification, it has some shortcomings for cases of limited data and complex models. In these cases the networks tend to be overconfident in their prediction even when erroneous - something that exposes its applications to risk. READ MORE

  3. 3. Validation Based Cascade-Correlation Training of Artificial Neural Networks

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik

    Author : John Ringdahl; [2020]
    Keywords : Machine learning; Artificial Neural Networks; Constructive; Cascade-Correlation; Validation Based; Physics and Astronomy;

    Abstract : The Cascade-Correlation learning algorithm, Cascor, is a self-constructive learning algorithm introduced by Fahlman in 1990, which builds the networks one node at the time based on the errors of the network. Cascor has been criticized for creating excessively deep networks and easily overfit. READ MORE

  4. 4. 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

  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
