3. 2. Machine Learning in Electricity Load Forecasting of Prosumer Buildings

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Lu Zhao; [2021]
   Nyckelord :;

   Sammanfattning : Short-term load forecasting plays a key role in energy optimizations such as peaking shaving and cost arbitrage. Forecasting the aggregated load of a city or region has been researched for years and produced accurate results with time lead ranging from an hour to a week. LÄS MER

4. 3. BLE Beacon Based Indoor Positioning System in an Office Building using Machine Learning

   Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

5. 4. Prediktioner av allsvenska fotbollsmatcher - Modellering och testande av strategier för satsning av kapital på spelbolagsmarknaden

   Kandidat-uppsats, Lunds universitet/Statistiska institutionen

   Författare :André Christiansen; [2019]
   Nyckelord :Expected Goals; xG; predictions; logistic regression; football; soccer; Mathematics and Statistics;

   Sammanfattning : This paper investigates if there is a quantitative relationship between Expected Goals (xG) and results in football games for the Swedish top-ranked league, Allsvenskan. Multicategory logit models are fitted with different types of explanatory xG-variables to see if these models can give better predictions than the bookmakers, and if there’s a possibility of generating a positive return using different betting strategies.
