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 does rolling mean in time?
Rolling is a very useful operation for time series data. Rolling means creating a rolling window with a specified size and perform calculations on the data in this window which, of course, rolls through the data .
Read moreWhat is an example of feature engineering?
Feature Engineering Example: Continuous data It can take any values from a given range. For example, it can be the price of some product, the temperature in some industrial process or coordinates of some object on the map. Feature generation here relays mostly on the domain data.
