Feature extraction is the practice of enhancing machine learning by finding characteristics in the data that help solve a particular problem . For time series data, feature extraction can be performed using various time series analysis and decomposition techniques.
Read moreWhat are the features of time series?
When plotted, many time series exhibit one or more of the following features:
Read moreWhat is feature generation?
Feature generation is the process of creating new features from one or multiple existing features, potentially for use in statistical analysis . This process adds new information to be accessible during the model construction and therefore hopefully result in a more accurate model.
Read moreAre Lstms good for time series?
Using LSTM, time series forecasting models can predict future values based on previous, sequential data . This provides greater accuracy for demand forecasters which results in better decision making for the business.
Read moreWhat is the best time series model?
ARIMA and SARIMA AutoRegressive Integrated Moving Average (ARIMA) models are among the most widely used time series forecasting techniques: In an Autoregressive model, the forecasts correspond to a linear combination of past values of the variable.
Read moreWhat is multivariate time series prediction?
A Multivariate time series has more than one time-dependent variable . Each variable depends not only on its past values but also has some dependency on other variables. This dependency is used for forecasting future values.
