  1. 1. Preoperative prediction of sentinel nodal status using mammography images

    University essay from Lunds universitet/Matematisk statistik

    Author : Malin Hjärtström; Maren Høibø; [2021]
    Keywords : Mathematics and Statistics;

    Abstract : Breast cancer is the most common cancer among women in Sweden, accounting for approximately 30 % of the cancer cases. The overall prognosis is good, but worsens if the cancer metastasizes from the primary tumor. READ MORE

  2. 2. Scenario Dose Calculation for Robust Optimization in Proton Therapy Treatment Planning

    University essay from Lunds universitet/Matematik LTH

    Author : Johan Sundström; [2021]
    Keywords : cancer; radiation therapy; proton therapy; treatment planning; robust optimization; dose calculation algorithms; scenarios; patient setup; range error; organ motion; pencil beam scanning; computational efficiency; range-corrected dose-mapping; Mathematics and Statistics;

    Abstract : Robust optimization plays a vital role in proton therapy treatment planning. A monoenergetic beam of protons has a finite range and delivers most of its dose at some specific depth in the patient. This allows the design of treatments that mainly damage the tumor and not any surrounding tissue. READ MORE

  3. 3. Classification of EEG Data Using Convolutional Neural Networks and the Scaled Reassigned Spectrogram

    University essay from Lunds universitet/Matematisk statistik

    Author : Karin Pagels; [2021]
    Keywords : Mathematics and Statistics;

    Abstract : Electroencephalography (EEG) is a medical technique for measuring brain activity through several channels connected to the scalp. Interpreting EEG data is a difficult problem because of the large amount of noise contained in the data. READ MORE

  4. 4. 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

  5. 5. Generative Adversarial Networks in Lip-Synchronized Deepfakes for Personalized Video Messages

    University essay from Lunds universitet/Matematik LTH

    Author : Johan Liljegren; Pontus Nordqvist; [2021]
    Keywords : Generative Adversarial Networks; GAN; Lip-Synchronization; Deepfake; Deep Learning; Autoencoder; WGAN; WGAN-GP; L1WGAN-GP; Skip-Connections; FID-Score; Mathematics and Statistics; Technology and Engineering;

    Abstract : The recent progress of deep learning has enabled more powerful frameworks to create good-quality deepfakes. Deepfakes, which are mostly known for malicious purposes, have great potential to be useful in areas such as the movie industry, education, and personalized messaging. READ MORE
