  1. 1. Track Before Detect in Active Sonar Systems

    University essay from Uppsala universitet/Signaler och system

    Author : Johnny Ljung; [2021]
    Keywords : signal processing; active sonar systems; track-before-detect; target tracking; reverberation; signalbehandling; aktiva sonarsystem; spårning innan detektion; målspårning; reverberation;

    Abstract : Detection of an underwater target with active sonar in shallow waters such as the Baltic sea is a big challenge. This since the sound beams from the sonar will be reflected on the surfaces, sea surface and sea bottom, and the water volume itself which generates reverberation. READ MORE

  3. 2. A Bayesian Filtering Approach to Incorporate Views in Economic Scenario Generation

    University essay from Lunds universitet/Matematisk statistik

    Author : Arvid Cederberg; [2020]
    Keywords : Mathematics and Statistics;

    Abstract : .... READ MORE

  4. 3. Traffic State Estimation for Signalized Intersections : A Combined Gaussian Process Bayesian Filter Approach

    University essay from KTH/Transportplanering

    Author : Michael Sederlin; [2020]
    Keywords : Traffic State Estimation; Traffic Flow modelling; Gaussian Processes; Bayesian Filtering; Kalman Filter; Traffic Signals; Intersection; Non-parametric;

    Abstract : Traffic State Estimation (TSE) is a vital component in traffic control which requires an accurate viewof the current traffic situation. Since there is no full sensor coverage and the collected measurementsare inflicted with random noise, statistical estimation techniques are necessary to accomplish this. READ MORE

  5. 4. Recommender System for Gym Customers

    University essay from Linköpings universitet/Statistik och maskininlärning

    Author : Roshni Sundaramurthy; [2020]
    Keywords : Recommender system; collaborative filtering; matrix factorization; sparse matrix; latent semantic analysis; singular value decomposition; alternating least square; Bayesian personalized ranking; logistic matrix factorization; stochastic gradient descent; AUC metric; mean average precision; normalized discounted cumulative gain; Rekommendationssystem;

    Abstract : Recommender systems provide new opportunities for retrieving personalized information on the Internet. Due to the availability of big data, the fitness industries are now focusing on building an efficient recommender system for their end-users. This thesis investigates the possibilities of building an efficient recommender system for gym users. READ MORE

  6. 5. An application of Bayesian Hidden Markov Models to explore traffic flow conditions in an urban area

    University essay from Uppsala universitet/Statistiska institutionen

    Author : Lovisa Andersson; [2019]
    Keywords : Bayesian statistics; hidden states; Markov chain; traffic flow modeling; filtering; smoothing; most probable state sequence; MCMC; Hamiltonian Monte Carlo; No-U-Turn sampler;

    Abstract : This study employs Bayesian Hidden Markov Models as method to explore vehicle traffic flow conditions in an urban area in Stockholm, based on sensor data from separate road positions. Inter-arrival times are used as the observed sequences. READ MORE
