You can use the built-in Pandas functions to do it: df ["Time stamp"] = pd.to_datetime (df ["Time stamp"]) # Convert column type to be datetime indexed_df = df.set_index ( ["Time stamp"]) # Create a datetime index indexed_df.rolling (100) # Create rolling windows indexed_df.rolling (100).mean () # Then apply functions … NettetYou can think of it as shifting a cut-out window over your sorted time series data: on each shift step you extract the data you see through your cut-out window to build a new, smaller time series and extract features only on this one. Then you continue shifting.
