  1. 1. Causal Discovery for Time Series : Based on Continuous Optimization

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Ali Nouri; [2023]
    Keywords : ;

    Abstract : Causal discovery is an important field of study that seeks to understand the underlying relationships between variables in a system. The goal of causal discovery is to discover the causal relationships from observational data and determine the direction of influence between variables. READ MORE

  3. 2. Ocean rogue wave analysis for the development of safer navigation systems. : A Thesis submitted to the University of Gävle for the degree of Bachelor of Mathematics

    University essay from Högskolan i Gävle/Matematik

    Author : Sergio Manzetti; [2023]
    Keywords : ;

    Abstract : Rogue waves are unexpectedly high waves of 2.5X the significant wave height and which occur in nearly all phases of nature, from  oceans, to fiber-optic cables and atmospheric air-masses. In the ocean, rogue waves pose a significant danger to shipping and fishing vessels and have been found to reach 27. READ MORE

  4. 3. LSTM-based Directional Stock Price Forecasting for Intraday Quantitative Trading

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

    Author : Isabella Mustén Ross; [2023]
    Keywords : Deep Learning; Long-Short-Term-Memory LSTM ; ARIMA; Financial Time Series Forecasting; Algorithmic Trading; Intraday Trading; Stock Prediction; Djupinlärning; LSTM; ARIMA; finansiella tidsserier; algoritmisk aktiehandel; intradagshandel; aktieprediktion;

    Abstract : Deep learning techniques have exhibited remarkable capabilities in capturing nonlinear patterns and dependencies in time series data. Therefore, this study investigates the application of the Long-Short-Term-Memory (LSTM) algorithm for stock price prediction in intraday quantitative trading using Swedish stocks in the OMXS30 index from February 28, 2013, to March 1, 2023.

  5. 4. Developing a web-based system to visualize vegetation trends by a nonlinear regression algorithm

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Yufei Wei; [2016]
    Keywords : PolyTrend; nonlinear regression algorithm; vegetation trends; Physical Geography and Ecosystem Analysis; NDVI; Web Development; Django; MATLAB; Python; Earth and Environmental Sciences;

    Abstract : Comparing with traditional linear regression methods that used to monitor vegetation trends, a nonlinear regression algorithm (PolyTrend) developed by Jamali et al. (2014) can provide more accurate information of vegetation trends by fitting a polynomial line with a degree of up to three for ASCII-formed time-series NDVI (Normalized Difference Vegetation Index) dataset of a single pixel.
