  1. 31. Optimizing the Number of Time-steps Used in Option Pricing

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Hugo Lewenhaupt; [2019]
    Keywords : Option pricing; binomial trees; machine learning; deep learning; discretization methods; optimization; recombinant tree; convergence;

    Abstract : Calculating the price of an option commonly uses numerical methods and can becomputationally heavy. In general, longer computations result in a more precisresult. As such, improving existing models or creating new models have been thefocus in the research field. READ MORE

  3. 32. Factors affecting damage to Scots pine in a multiple ungulate species system

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Matthew Knibb; [2018]
    Keywords : ungulate; browsing damage; dung pellet group counts; land use; weather;

    Abstract : Managing browsing impacts on commercial forestry is one of the main aims of ungulate management in Sweden, with Scots Pine being one of the major forestry species. Moose is the ungulate species with the greatest management focus, although in parts of Sweden it is forms a multiple ungulate species system, along with red deer, roe deer and fallow deer. READ MORE

  4. 33. A COMPARATIVE STUDY OF DEEP-LEARNING APPROACHES FOR ACTIVITY RECOGNITION USING SENSOR DATA IN SMART OFFICE ENVIRONMENTS

    University essay from Malmö universitet/Fakulteten för teknik och samhälle (TS)

    Author : Alexander Johansson; Oscar Sandberg; [2018]
    Keywords : Deep learning; Human activity recognition; IoT technology; CNN; RNN; LSTM; DNN; Decision tree; Tensorflow;

    Abstract : Syftet med studien är att jämföra tre deep learning nätverk med varandra för att ta reda på vilket nätverk som kan producera den högsta uppmätta noggrannheten. Noggrannheten mäts genom att nätverken försöker förutspå antalet personer som vistas i rummet där observation äger rum. READ MORE

  5. 34. Term Structure Modeling near the Zero Lower Bound: Regime Switching & Monetary Policy

    University essay from Handelshögskolan i Stockholm/Institutionen för nationalekonomi

    Author : Oliver Krek; [2018]
    Keywords : Affine Term Structure Model; Regime Switching; Monetary Policy; Zero Lower Bound;

    Abstract : This thesis proposes a regime-switching extension to the well known autoregressive gamma and gamma-zero process nesting its linear counterpart. The affine term structure model based on the new process matches key stylized facts of interest rates during a zero lower bound period as well as in normal times. READ MORE

  6. 35. Implementing Streaming Parallel Decision Trees on Graphic Processing Units

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : David Svantesson; [2018]
    Keywords : decision trees; streaming; gpu; hpc; spdt; streaming parallel decision trees; machine learning;

    Abstract : Decision trees have long been a prevalent area within machine learning. With streaming data environments as well as large datasets becoming increasingly common, researchers have developed decision tree algorithms adapted to streaming data. READ MORE
