  1. 26. Federated Neural Collaborative Filtering for privacy-preserving recommender systems

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Johannes Langelaar; Adam Strömme Mattsson; [2021]
    Keywords : Machine learning; Federated learning; Deep learning; Artificial intelligence; AI; Neural networks; Recommender systems; Recommendation systems; Collaborative filtering; Privacy; Federated averaging; Movielens;

    Abstract : In this thesis a number of models for recommender systems are explored, all using collaborative filtering to produce their recommendations. Extra focus is put on two models: Matrix Factorization, which is a linear model and Multi-Layer Perceptron, which is a non-linear model. READ MORE

  3. 27. Subsampling Strategies for Bayesian Variable Selection and Model Averaging in GLM and BGNLM

    University essay from Stockholms universitet/Statistiska institutionen

    Author : Jon Lachmann; [2021]
    Keywords : Bayesian model averaging; subsampling; GLM; BGNLM; IRLS; Optimisation;

    Abstract : Bayesian Generalized Nonlinear Models (BGNLM) offer a flexible alternative to GLM while still providing better interpretability than machine learning techniques such as neural networks. In BGNLM, the methods of Bayesian Variable Selection and Model Averaging are applied in an extended GLM setting. READ MORE

  4. 28. Investigation on Positioning Techniques for Indoor Office Scenario

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

    Author : Yan Shu; Yujie Zhang; [2020]
    Keywords : Technology and Engineering;

    Abstract : This master thesis aims to investigate downlink positioning techniques and improve fifth-generation (5G) cellular positioning performance in the indoor office scenario. In the thesis work, we target in the indoor office scenario because it is a typical deployment scenario standardized in 3GPP release 16. READ MORE

  5. 29. Weather Influence on LiDAR Signals using the Transient Radiative Transfer and LiDAR Equations

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Marcus Hedlund; [2020]
    Keywords : Radiative transfer; LiDAR; Transient radiative transfer;

    Abstract : The ongoing development of self driving cars requires accurate measuring devices and the objective of this thesis was to investigate how di↵erent weather will affect one of these devices, known as a LiDAR. A LiDAR uses pulsed laser light to measure the distance to an object. READ MORE
