  1. 1. A GP-Surrogate-Based Bayesian Framework for Surge Barrier Optimization

    University essay from KTH/Matematik (Avd.)

    Author : Abel Valko; [2022]
    Keywords : Bayesian Optimization; Gaussian Process Regression; Storm Surge; GeoClaw; GISSR;

    Abstract : Tropical cyclone induced storm surges are some of the largest environmental risks facing infrastructure and human life in dense urban environments. Hurricane Sandy caused 44 deaths and damage of 19 billion US dollars in New York City alone. READ MORE

  2. 2. Cost optimization in the cloud : An analysis on how to apply an optimization framework to the procurement of cloud contracts at Spotify

    University essay from Linköpings universitet/Produktionsekonomi

    Author : Harald Ekholm; Daniel Englund; [2020]
    Keywords : cloud computing; Spotify; monte carlo; MC; stochastic processes; stochastic programming; Google Cloud Platform; GCP; IT; computational resources; optimization; cost optimization; forecast; procurement;

    Abstract : In the modern era of IT, cloud computing is becoming the new standard. Companies have gone from owning their own data centers to procuring virtualized computational resources as a service. This technology opens up for elasticity and cost savings. Computational resources have gone from being a capital expenditure to an operational expenditure. READ MORE

  3. 3. AUTOMATED OPTIMAL FORECASTING OF UNIVARIATE MONITORING PROCESSES : Employing a novel optimal forecast methodology to define four classes of forecast approaches and testing them on real-life monitoring processes

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

    Author : Stanislav Razroev; [2019]
    Keywords : predictions; forecasting; optimal forecasting; forecast classes; optimality rules; ensemble forecasting; state switching; combinational forecasting; optimality framework; exponential smoothing; ARIMA; ARMA; SARIMA; Double-Seasonal Holt-Winters; time series; Wikipedia; Wikimedia; Wikipedia data; Twitter; Twitter data; electricity data; monitoring processes; monitoring process; monitoring; error metrics; outliers; missing values;

    Abstract : This work aims to explore practical one-step-ahead forecasting of structurally changing data, an unstable behaviour, that real-life data connected to human activity often exhibit. This setting can be characterized as monitoring process. READ MORE

  4. 4. Application of Machine Learning techniques to Optimization algorithms

    University essay from KTH/Optimeringslära och systemteori

    Author : Geoffrey Dabert; [2017]
    Keywords : ;

    Abstract : Optimization problems have been immuned to any attempt of combination with machine learning until a decade ago but it is now an active research field. This thesis has studied the potential implementation of a machine learning heuristic to improve the resolution of the optimization scheduling problems based on a Constraint Programming solver.

  5. 5. Back to a General Theory - An Essay in Persuasion

    University essay from Handelshögskolan i Stockholm/Institutionen för nationalekonomi

    Author : Georg Meier; Petter Svärd; [2017]
    Keywords : Keynes; DSGE model; ergodicity; effective demand; tripartite economics;

    Abstract : Many Western countries experience failing monetary policy after the 2008 financial crisis. The lack of alternatives to established rules, even when they appear to fail, motivates a close look at the economic ideas John Maynard Keynes developed in his crisis-ridden lifetime, to answer the question: What can Keynes' writings contribute to the contemporary macroeconomic discussion? We trace from the publication of the General Theory (1936) until our time how macroeconomics has narrowed down into theoretical consensus, elevating policy recommendations developed in moderate times to an exclusive status of optimality.
