  1. 26. Deep Learning for Dynamic Portfolio Optimization

    University essay from KTH/Matematisk statistik

    Author : Victor Molnö; [2021]
    Keywords : Dynamic portfolio optimization; No-trade-region; Deep learning; Policy iteration; Dynamisk portföljoptimering; Handelsstoppregion; Djupinlärning; Policyiterering;

    Abstract : This thesis considers a deep learning approach to a dynamic portfolio optimization problem. A proposed deep learning algorithm is tested on a simplified version of the problem with promising results, which suggest continued testing of the algorithm, on a larger scale for the original problem.

  3. 27. Calibration of Breast Cancer Natural History Models Using Approximate Bayesian Computation

    University essay from KTH/Matematisk statistik

    Author : Oscar Bergqvist; [2020]
    Keywords : Approximate Bayesian Computation; ABC; breast cancer natural history models; random effects; Bayesian statistics; likelihood-free inference; Approximate Bayesian computation; ABC; natural history models för bröstcancer; random effects; bayesiansk statistik; likelihood-fri inferens;

    Abstract : Natural history models for breast cancer describe the unobservable disease progression. These models can either be fitted using likelihood-based estimation to data on individual tumour characteristics, or calibrated to fit statistics at a population level. READ MORE

  4. 28. Radar Target detection using Cell Evaluation Method for Industrial Safety

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

    Author : Praanesh Sambath; [2020]
    Keywords : Functional Safety System; Conventional methods; Cell Evaluation Method; Radar Target detection; Angular Estimation.; Maskinsäkerhet; CFAR; Radar detection; Angular Estimation.;

    Abstract : The main aim of using radars in industrial safety system is to detect the presence of target accurately. The conventional methods of radar target detection algorithm such as the Cell averaging constant false alarm rate method (CA-CFAR), Greatest of constant false alarm method (GO-CFAR) and the Smallest of constant false alarm rate method (SO-CFAR) has their own disadvantage when it comes to precise target detection which is a key factor for a safety system.

  5. 29. Estimation of roughage intake for dairy cows based on eating time and individual intake rate

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Sara Pihl; [2020]
    Keywords : roughage; dairy cows; intake rate; silage; silage intake estimation;

    Abstract : Prediktering av foderintag för mjölkkor är en viktig aspekt att ta hänsyn till både ur djurvälfärdssynpunkt men även ekonomiskt då foder är en av de största utgifterna inom svensk mjölkproduktion. Precis prediktering av foderintag är viktigt för att und-vika att över- eller underutfodra sina djur vilket i sin tur kan leda till sjukdomar hos djuren och/eller högre omkostnader. READ MORE

  6. 30. Image Distance Learning for Probabilistic Dose–Volume Histogram and Spatial Dose Prediction in Radiation Therapy Treatment Planning

    University essay from KTH/Matematisk statistik

    Author : Ivar Eriksson; [2020]
    Keywords : Radiation therapy; automated planning; machine learning; autoencoder; distance optimisation; sparse pseudo-input Gaussian process; kernel density estimation; dose mimicking; dose–volume histogram; Strålbehandling; automatiserad dosplanering; maskininlärning; autoencoder; distansoptimering; glesa Gaussiska processer; sannolikhets-fördelnings-estimering; dosrekonstruktion; dos–volymhistogram;

    Abstract : Construction of radiotherapy treatments for cancer is a laborious and time consuming task. At the same time, when presented with a treatment plan, an oncologist can quickly judge whether or not it is suitable. This means that the problem of constructing these treatment plans is well suited for automation. READ MORE
