  1. 1. Convergence Properties for Different Null Space Bases When Solving the Initial Margin Optimization Problem Using CMA-ES

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

    Author : Jacob Barnholdt; Filip Carlsson; [2020]
    Keywords : Financial mathematics; CMA-ES; Optimization; Initial Margin; Null space representations; Finansiell matematik; CMA-ES; Optimering; Initial Margin; Nollrumsrepresentationer;

    Abstract : This thesis evaluates how the evolutionary algorithm CMA-ES (Covariance Matrix Adaption Evolution Strategy) can be used for optimizing the total initial margin for a network of banks trading bilateral OTC derivatives. The algorithm is a stochastic method for optimization of non-linear and, but not limited to, non-convex functions. READ MORE

  3. 3. Dispersion management and characterization of ultrashort laser pulses for the optimization of parametric processes

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Axel Elfving; [2019]
    Keywords : frequency resolved optical gating; optical parametric amplification; difference frequency generation; nonlinear optics; laser pulse compression; lasers; optics; Technology and Engineering; Physics and Astronomy;

    Abstract : This thesis set out to continue the development of a short-wave infrared (SWIR) optical parametric amplifier (OPA). The system is based on a Yb-ber chirped pulse amplification (CPA) laser delivering 400 fs long pulses, centered around 1030 nm, at 200 kHz repetition rate and 40 W average power. READ MORE

  4. 4. A study on the application of machine learning algorithms in stochastic optimal control

    University essay from KTH/Matematisk statistik

    Author : Xin Huang; [2019]
    Keywords : ;

    Abstract : By observing a similarity between the goal of stochastic optimal control to minimize an expected cost functional and the aim of machine learning to minimize an expected loss function, a method of applying machine learning algorithm to approximate the optimal control function is established and implemented via neural approximation. Based on a discretization framework, a recursive formula for the gradient of the approximated cost functional on the parameters of neural network is derived. READ MORE

  5. 5. The Information Bottleneck : Connections to Other Problems, Learning and Exploration of the IB Curve

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

    Author : Borja Rodriguez Galvez; [2019]
    Keywords : ;

    Abstract : In this thesis we study the information bottleneck (IB) method. This is an informationtheoretic framework which addresses the question of what are the relevant factors of arandom variable X to explain another statistically dependent random variable Y . Thesefactors are embedded into a bottleneck variable T obeying the Markov condition Y $X $ T. READ MORE
