1. 21. Using Data-Driven Feasible Region Approximations to Handle Nonlinear Constraints When Applying CMA-ES to the Initial Margin Optimization Problem

   University essay from KTH/Matematisk statistik

   Author : Karl Wallström; [2021]
   Keywords : Optimization; Initial margin; Evolutionary algorithms; CMA-ES; Support vector machines; Boundary constraint handling; Nonlinear constraints; Repair algorithms; Feasible region approximation; Optimering; Initial margin; Evolutionära algoritmer; CMA-ES; Support vector machines; Hantering av bivillkor; Icke-linjära bivillkor; Reparationsalgoritmer; Approximation av tillåtet område;

   Abstract : The introduction of initial margin requirements for non-cleared OTC derivatives has made it possible to optimize initial margin when considering a network of trading participants. Applying CMA-ES, this thesis has explored a new method to handle the nonlinear constraints present in the initial margin optimization problem. READ MORE

3. 22. Offline Reinforcement Learning for Remote Electrical Tilt Optimization : An application of Conservative Q-Learning

   University essay from KTH/Matematik (Avd.)

   Author : Marcus Kastengren; [2021]
   Keywords : Remote Electrical Tilt; Antenna Tilt Optimization; Reinforcement Learning; Offline Reinforcement Learning; Conservative Q-Learning; Fjärrlutning; Antennlutningsoptimering; Förstärkningsinlärning; Offline-förstärkningsinlärning; Konservativ Q-inlärning;

   Abstract : In telecom networks adjusting the tilt of antennas in an optimal manner, the so called remote electrical tilt (RET) optimization, is a method to ensure quality of service (QoS) for network users. Tilt adjustments made during operations in real-world networks are usually executed through a suboptimal policy, and a significant amount of data is collected during the execution of such policy.

4. 23. Coordinate conversion for the Hough transform

   University essay from Uppsala universitet/Högenergifysik

   Author : Edvin Eriksson; [2021]
   Keywords : particle accelerator; coordinate transformation; hough transform; uppsala; bachelor thesis; kandidatarbete; uppsala; fysik;

   Abstract : This thesis attempts to develop a conversion algorithm between local coordinates in constituent detector modules and global coordinates encompassing the whole detector structure in a generic detector. The thesis is a part of preparatory work for studying the Hough Transform as a means of track reconstruction in the level-1 hardware trigger in the upgraded trigger and data acquisition (TDAQ) system in the phase 2 upgrade of the ATLAS detector at CERN.

5. 24. Gate Recurrent Unit Neural Networks for Hearing Instruments

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Harshit Sharma; Pallavi Rajanna; [2020]
   Keywords : Keyword Spotting; GRU; Gated; Recurrent; Unint; RNN; Hearing Instruments; Hearing; Instruments.; Technology and Engineering;

   Abstract : Gated Recurrent Unit (GRU) neural networks have gained popularity for applications such as keyword spotting, speech recognition and other artificial intelligence applications. Typically for most applications training and inference is performed on cloud servers, and the result are transferred to the power constrained device, e.g. READ MORE

6. 25. Music Recommendations; Approximating user distributions to address the cold start problem

   University essay from Lunds universitet/Statistiska institutionen

   Author : Johan Hammarstedt; [2020]
   Keywords : Music recommendation Content based filtering Collaborative filtering Matrix factorization user-feature distribution; Technology and Engineering;

   Abstract : In today's data driven society the world is at a point of information overload. As people rely on Google for information and other platforms such as Netflix and Spotify for entertainment, the need for relevant filtering of content has never been higher. As a result, recommendation systems have seen a great surge in demand. READ MORE
