UCI dataset

Dataset from UCI contains the  electricity consumption (in kWh) of 320 customers every 15 minutes from 2011 to 2014.     For  some customers, their electricity consumption data was recorded starting from a different time,  and the data before the first record was marked as 0.     As training model requires a starting point for the time series, and different customers  have different starting times, some features remain 0 before a certain time point.     Using all  the data for training would inevitably have a negative impact.     Therefore, the data  from 2011 is removed  and set the starting time to January 1, 2012.     Additionally, the data is converted into  hourly consumption using mathematical methods to extract features and reduce the data volume.     Hence, the preprocessed data contains the hourly electricity consumption of each object from 2012 to 2014.

Here is the data after processing.
