  1. 16. Identifying Machine States and Sensor Properties for a Digital Machine Template : Automatically recognize states in a machine using multivariate time series cluster analysis

    University essay from Mittuniversitetet/Institutionen för informationssystem och –teknologi

    Author : Jakob Viking; [2021]
    Keywords : Digital twin; Digital shadow; Unsupervised learning; Cluster analysis; HDBSCAN; Chi-squared goodness of fit test;

    Abstract : Digital twins have become a large part of new cyber-physical systems as they allow for the simulation of a physical object in the digital world. In addition to the new approaches of digital twins, machines have become more intelligent, allowing them to produce more data than ever before. READ MORE

  3. 17. Multivariate Short-term Electricity Load Forecasting with Deep Learning and exogenous covariates

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Nordström Oscar; [2021]
    Keywords : Machine learning; Time series; Deep learning; Forecasting; Short-term electricity load forecasting; Artificial Neural Network;

    Abstract : Maintaining the electricity balance between supply and demand is a challenge for electricity suppliers. If there is an under or overproduction, it entails financial costs and affects consumers and the climate. To better understand how to maintain the balance, can the suppliers use short-term forecasts of electricity load. READ MORE

  4. 18. Visual Analysis of Industrial Multivariate Time-Series Data : Effective Solution to Maximise Insights from Blow Moulding Machine Sensory Data

    Keywords : automated factories; multivariate time-series; unsupervised machine learning; visual analytics;

    Abstract : Developments in the field of data analytics provides a boost for small-sized factories. These factories are eager to take full advantage of the potential insights in the remotely collected data to minimise cost and maximise quality and profit. READ MORE

  5. 19. Predictive Analysis of Heating Systems for Fault Detection

    University essay from Blekinge Tekniska Högskola

    Author : Syam Kumar Vemana; Sai Keerthi Applili; [2021]
    Keywords : Machine Learning; Supervised Learning; Regression analysis; Fault detection; Predictive analysis;

    Abstract : Background : The heat load has an emergent role in the energy consumption of the heating system in buildings. The industry experts also have been constantly focusing on the heat load optimization techniques and in the recent years, numerous Machine Learning (ML) techniques have come into picture to resolve various tasks.

  6. 20. A comparative study of Neural Network Forecasting models on the M4 competition data

    University essay from Uppsala universitet/Statistiska institutionen

    Author : Markus Ridhagen; Petter Lind; [2021]
    Keywords : Time series analysis; M4; neural network; NN; artificial neural network; ANN; feedforward neural network; FNN; multilayer perceptron; MLP; recurrent neural network; RNN; long short-term memory; LSTM;

    Abstract : The development of machine learning research has provided statistical innovations and further developments within the field of time series analysis. This study seeks to investigate two different approaches on artificial neural network models based on different learning techniques, and answering how well the neural network approach compares with a basic autoregressive approach, as well as how the artificial neural network models compare to each other.
