Time-series data have core components like seasonality, trend, and cycles . For example, ice-cream sales usually have yearly seasonality — you can reasonably predict the next summer’s sales based on this year’s. Similarly, temperatures or air quality measurements have daily seasonality or also, yearly.
Read moreWhat is feature extraction with example?
Feature Extraction uses an object-based approach to classify imagery, where an object (also called segment) is a group of pixels with similar spectral, spatial, and/or texture attributes . Traditional classification methods are pixel-based, meaning that spectral information in each pixel is used to classify imagery.

There exist different types of Autoencoders such as:
Read moreHow do you extract time series features?
For time series data, feature extraction can be performed using various time series analysis and decomposition techniques . In addition, features can be obtained by sequence comparison techniques such as dynamic time warping and by subsequence discovery techniques such as motif analysis.
