  1. 11. Portfolio Risk Modelling in Venture Debt

    Master-uppsats, KTH/Matematisk statistik

    Författare :John Eriksson; Jacob Holmberg; [2023]
    Nyckelord :Startup Default Probability; Venture Debt; Gaussian Copula; Value-at-Risk; Expected Shortfall; Exposure at Default; Loss Given Default; Forecast; Linear Dynamic System; ARIMA Time Series; Monte Carlo Simulation; Linear Regression; Central Limit Theorem;

    Sammanfattning : This thesis project is an experimental study on how to approach quantitative portfolio credit risk modelling in Venture Debt portfolios. Facing a lack of applicable default data from ArK and publicly available sets, as well as seeking to capture companies that fail to service debt obligations before defaulting per se, we present an approach to risk modeling based on trends in revenue.

  3. 12. Evaluating machine learning models for time series forecasting in smart buildings

    M1-uppsats, KTH/Hälsoinformatik och logistik

    Författare :Sarugan Balachandran; Diego Perez Legrand; [2023]
    Nyckelord :Machine learning; supervised learning; time series forecasting; neural networks; LSTM; En- semble LSTM; AT-LSTM; ARIMA; XGBoost; Maskininlärning; övervakad inlärning; tidsserie-prognostisering; neurala nätverk; LSTM; En- semble LSTM; AT-LSTM; ARIMA; XGBoost;

    Sammanfattning : Temperature regulation in buildings can be tricky and expensive. A common problem when heating buildings is that an unnecessary amount of energy is supplied. This waste of energy is often caused by a faulty regulation system. LÄS MER

  4. 13. Forecasting Monthly Swedish Air Traveler Volumes

    Kandidat-uppsats, Uppsala universitet/Statistiska institutionen

    Författare :Mark Becker; Peter Jarvis; [2023]
    Nyckelord :Forecasting; SARIMA; Neural network autoregression; Exponential smoothing; the Prophet model; Random Walk; MAE; MAPE; RMSE;

    Sammanfattning : In this paper we conduct an out-of-sample forecasting exercise for monthly Swedish air traveler volumes. The models considered are multiplicative seasonal ARIMA, Neural network autoregression, Exponential smoothing, the Prophet model and a Random Walk as a benchmark model. LÄS MER

  5. 14. Do Inflation Expectations Granger Cause Inflation? A VEC Model Approach

    D-uppsats, Handelshögskolan i Stockholm/Institutionen för nationalekonomi

    Författare :Alice Hindersson; Siri Jäderberg; [2023]
    Nyckelord :Forecasting; Inflation; Inflation Expectations; VEC Model; Granger Causality;

    Sammanfattning : Being able to accurately predict future inflation is of great importance for a wide range of actors in the economy, as well as for the effectiveness of monetary policy decisions. In this thesis, we examine whether survey measures of inflation expectations contribute to more accurate inflation forecasts in Sweden. LÄS MER

  7. 15. Predicting Waveforms with Machine Learning for Efficient Triggering in Monitoring Systems

    Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Amanda Rautio; [2023]
    Nyckelord :;

    Sammanfattning : Energy systems need to evolve to meet the requirements of the modern world and the future. Hence, substantial effort is needed at an academic and industrial level to develop valuable diagnostic techniques. LÄS MER
