  1. 16. Simulating Broadband Analog Aggregation for Federated Learning

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

    Author : Linus Pekkanen; Patrik Johansson; [2020]
    Keywords : Federated learning; over-the-air computation; broadband analog aggregation;

    Abstract : With increasing amounts of data coming fromconnecting progressively more devices, new machine learningmodels have risen. For wireless networks the idea of using adistributed approach to machine learning has gained increasingpopularity, where all nodes in the network participate in creatinga global machine learning model by training with the localdata stored at each node, an example of this approach is calledfederated learning.

  3. 17. On two-component Bose-Einstein condensates in a ring

    University essay from Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Author : Marcus Sköld; [2019]
    Keywords : Mathematics and Statistics;

    Abstract : A Bose-Einstein condensate is a type of gas consisting of one or more types of particles called bosons which are cooled to a temperature very close the absolute zero. Under these conditions the particles all start to occupy their lowest quantum state. READ MORE

  4. 18. Machine Learning in credit risk : Evaluation of supervised machine learning models predicting credit risk in the financial sector

    University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

    Author : Love Lundström; Oscar Öhman; [2019]
    Keywords : Credit risk; probability of default; Logistic regression; Neural network; Decision tree; Random Forest; Kredit risk; sannolikheten att fallera; Logistisk regression; Neurala nätverk; Decision Tree; Random Forest;

    Abstract : When banks lend money to another party they face a risk that the borrower will not fulfill its obligation towards the bank. This risk is called credit risk and it’s the largest risk banks faces. According to the Basel accord banks need to have a certain amount of capital requirements to protect themselves towards future financial crisis. READ MORE

  5. 19. Online intra-day portfolio optimization using regime based models

    University essay from Lunds universitet/Matematisk statistik

    Author : Sara Hafström Fremlin; [2019]
    Keywords : Multi-period portfolio selection; Model predictive control; Hidden Markov model; Mathematics and Statistics;

    Abstract : In this thesis model predictive control (MPC) is used to dynamically optimize a portfolio where the data is sampled every 5 minutes. Previous research has shown how MPC optimization applied to daily sampled financial data can generate a portfolio that exceeds the value of standard portfolio strategies such as Strategic asset allocation.

  6. 20. Conformal field theory at large N

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Nadia Flodgren; [2019]
    Keywords : Conformal field theory; conformal bootstrap; large N; anti-de Sitter; anomalous dimension; AdS CFT correspondence;

    Abstract : The conformal bootstrap method is a non-perturbative method that uses the symmetry in a conformal field theory to constrain and solve for the observables in the theory. We consider a conformal field theory with the symmetry group SU(N) and four general scalar fields as the only low dimensional operators. READ MORE
