Special Issue Information

Dear Colleagues,

Time series data plays an important role in various fields, such as finance, meteorology, biomedicine, smart factories, etc. Time series forecasting (TSF) and classification (TSC) are key tasks aimed at identifying and predicting trends, patterns, and anomalies in these data. This Special Issue is looking for some advanced algorithms for time series forecasting and classification to promote their development and application in related fields. Potential topics include, but are not limited to:

  • Advanced algorithms for time series forecasting and classification, including improved traditional algorithms (such as ARIMA or SARIMA), machine learning algorithms (such as support vector machines, decision trees and neural networks) and deep learning algorithms (such as convolution neural networks (CNNs), long-short term memory (LSTM), etc.
  • Feature engineering algorithms for time series forecasting and classification, including feature extraction, dimensionality reduction, and selection to improve the accuracy and efficiency of forecasting and classification.
  • Case studies of time series forecasting and classification in practical applications, such as financial market forecasting, weather forecasting, stock market analysis, and fault diagnosis.
  • Application challenges of time series forecasting and classification algorithms in modeling and representation of time series data with high-noise, small-size time series data.

Together with the growing interest towards renewable energy sources within the framework of different strategies of various countries, the number of solar power plants keeps growing. However, managing optimal power generation for solar power plants has its own challenges. First comes the problem of work interruption and reduction in power generation. As the system must be tolerant to the faults, the relevance and significance of short-term forecasting of solar power generation becomes crucial. Within the framework of this research, the applicability of different forecasting methods for short-time forecasting is explained. The main goal of the research is to show an approach regarding how to make the forecast more accurate and overcome the above-mentioned challenges using opensource data as features. The data clustering algorithm based on KMeans is proposed to train unique models for specific groups of data samples to improve the generation forecast accuracy. Based on practical calculations, machine learning models based on Random Forest algorithm are selected which have been proven to have higher efficiency in predicting the generation of solar power plants. The proposed algorithm was successfully tested in practice, with an achieved accuracy near to 90%. Full article

Time series data typically exhibit high dimensionality and complexity, necessitating the use of specific approximation methods to perform computations on the data. The currently employed compression methods suffer from varying degrees of feature loss, leading to potential distortions in similarity measurement results. Considering the aforementioned challenges and concerns, this paper proposes a double mean representation method, SAX-DM (Symbolic Aggregate Approximation Based on Double Mean Representation), for time series data, along with a similarity measurement approach based on SAX-DM. Addressing the trade-off between compression ratio and accuracy in the improved SAX representation, SAX-DM utilizes the segment mean and the segment trend distance to represent corresponding segments of time series data. This method reduces the dimensionality of the original sequences while preserving the original features and trend information of the time series data, resulting in a unified representation of time series segments. Experimental results demonstrate that, under the same compression ratio, SAX-DM combined with its similarity measurement method achieves higher expression accuracy, balanced compression rate, and accuracy, compared to SAX-TD and SAX-BD, in over 80% of the UCR Time Series dataset. This approach improves the efficiency and precision of similarity calculation. Full article
