  1. 16. Using LSTM Neural Networks To Predict Daily Stock Returns

    University essay from Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Author : Jon William Cavallie Mester; [2021]
    Keywords : LSTM; RNN; stock prediction; deep learning;

    Abstract : Long short-term memory (LSTM) neural networks have been proven to be effective for time series prediction, even in some instances where the data is non-stationary. This lead us to examine their predictive ability of stock market returns, as the development of stock prices and returns tend to be a non-stationary time series. READ MORE

  2. 17. Causal discovery in conditional stationary time-series data : Towards causal discovery in videos

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

    Author : Carles Balsells Rodas; [2021]
    Keywords : Causality; Causal discovery; Neural networks; Graph neural network; Time series; Non-stationary; Orsakssamband; Kausal upptäckt; Neurala nätverk; Diagram Neurala nätverk; Tidsföljder; Icke-stationär;

    Abstract : Performing causal reasoning in a scene is an inherent mechanism in human cognition; however, the majority of approaches in the causality literature aiming for this task still consider constrained scenarios, such as simple physical systems or stationary time-series data. In this work we aim for causal discovery in videos concerning realistic scenarios. READ MORE

  3. 18. Approaching sustainable mobility utilizing graph neural networks

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Robin Gunnarsson; Alexander Åkermark; [2021]
    Keywords : Graph neural network; GNN; sustainable mobility; GCN; graph; Neural network; Cora; Fuel consumption prediction; graph;

    Abstract : This report is done in collaboration with WirelessCar for the master of science thesis at Halmstad University. Many different parameters influence fuel consumption. The objective of the report is to evaluate if Graph neural networks are a practical model to perform fuel consumption prediction on areas. READ MORE

  4. 19. Evaluation of Real-Time Single-Object Tracking Algorithms in a Non-Stationary Robotic Agent

    University essay from Lunds universitet/Kognitionsvetenskap

    Author : Pierre Klintefors; [2021]
    Keywords : Object Tracking; Computer Vision; Humanoid; Cognitive Science; Correlation Filter; Deep Learning; Object Tracking Evaluation; Technology and Engineering;

    Abstract : Visual object tracking is a fairly easy task for humans but a challenging problem in computer vision and thereby in humanoid implementation. Most of the existing object tracking evaluations are performed with prerecorded video footage, often with a stationary camera. This is not representative of a humanoid platform. READ MORE

  5. 20. An extreme value approach to modelling number of causalities in earthquakes

    University essay from Lunds universitet/Matematisk statistik

    Author : Henrik Steneld; [2021]
    Keywords : Extreme Value Theory; Point Process; Earthquakes; Mathematics and Statistics;

    Abstract : Earthquakes occur around the globe all the time. Most are weak enough to just pass by, some are strong enough to be felt by us humans, and some very few are completely devastating. A comprehensive database distributed by NOAA National Centers for Environmental Information provides a means for reviewing devastating earthquakes over the past. READ MORE
