   Kandidat-uppsats, SLU/School for Forest Management

   Författare :Felix Nilsson; Joakim Bengtsdahl; [2023]
   Nyckelord :gallring; uppföljning; laserskanning;

   Sammanfattning : Gallring är en av de skogsvårdsåtgärder som utförs i våra skogar för att bemöta de olika skogliga mål som skogsägarna har för sin skog. I Sveriges skogar så utförs gallringsåtgärder på ca 400 000 hektar årligen. LÄS MER

   Sammanfattning : Artificial intelligence techniques, such as artificial neural networks, random forests, or support vector machines, have been used to address a variety of problems in numerous industries. However, in many cases, models have to deal with issues such as imbalanced data or high multi-dimensionality. LÄS MER

5. 9. COMPARATIVE ANALYSIS OF MACHINE LEARNING LOAD FORECASTING TECHNIQUES

   Magister-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

   Författare :Humphry Takang Bate; [2023]
   Nyckelord :;

   Sammanfattning : Load forecasting plays a critical role in energy management, and power systems, enabling efficient resource allocation, improved grid stability, and effective energy planning and distribution. Without accurate very short term load forecasting, utility management companies face uncertain load patterns, unrealistic prices, and poor infrastructure planning. LÄS MER

7. 10. A Causal Analysis of Cat Bond Markets

   D-uppsats, Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

   Författare :Tim Matheis; [2023]
   Nyckelord :Cat bonds; Insurance-linked securities; Causal machine learning; Random forests;

   Sammanfattning : This work is a contribution to the causal analysis of the catastrophe bond market, which has generated high excess returns over the last two decades. Since these excess returns remain partially unexplainable and the interest in catastrophe bonds is increasing, the causal study of the factors affecting their premiums is of high relevance. LÄS MER
