The time series included yearly, quarterly, monthly, daily, and other time series. In order to ensure that enough data was available to develop an accurate forecasting model, minimum thresholds were set for the number of observations: 14 for yearly series, 16 for quarterly series, 48 for monthly series, and 60 for other series.

Kaggle is a data science competition platform and online community for data scientists and machine learning practitioners under Google LLC.Kaggle enables users to find and publish datasets, explore and build models in a web-based data science environment, work with other data scientists and machine learning engineers, and enter competitions to solve data science challenges.
Time-series of mel-frequency cepstrum coefficients. 8,800 Text Classification 2010 [124] [125] M. Bedda et al. ISOLET Dataset Spoken letter names. Features extracted from sounds. 7797 Text Classification 1994 [126] [127] R. Cole et al. Japanese Vowels Dataset Nine male speakers uttered two Japanese vowels successively.
Panel data is the general class, a multidimensional data set, whereas a time series data set is a one-dimensional panel (as is a cross-sectional dataset). A data set may exhibit characteristics of both panel data and time series data. One way to tell is to ask what makes one data record unique from the other records.
Bayesian structural time series (BSTS) model is a statistical technique used for feature selection, time series forecasting, nowcasting, inferring causal impact and other applications. The model is designed to work with time series data. The model has also promising application in the field of analytical marketing. In particular, it can be used ...
Time series datasets are relatively large and uniform compared to other datasets―usually being composed of a timestamp and associated data. [6] Time series datasets can also have fewer relationships between data entries in different tables and don't require indefinite storage of entries. [6]
In early studies, ESNs were shown to perform well on time series prediction tasks from synthetic datasets. [ 1 ] [ 17 ] Today, many of the problems that made RNNs slow and error-prone have been addressed with the advent of autodifferentiation (deep learning) libraries, as well as more stable architectures such as long short-term memory and ...
The trajectory matrix of multi-channel time series consists of linked trajectory matrices of separate times series. The rest of the algorithm is the same as in the univariate case. System of series can be forecasted analogously to SSA recurrent and vector algorithms (Golyandina and Stepanov, 2005).
