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.

本数据集源自 UCI，涵盖了2011年至2014年期间320名客户每15分钟一次的电力消耗（单位：千瓦时）。对于部分客户，其电力消耗数据记录起始时间存在差异，而起始记录之前的数据被标记为0。由于训练模型需要时间序列的起始点，且不同客户的起始时间各异，导致某些特征在特定时间点之前均为0。若将所有数据用于训练，不可避免地会对模型产生负面影响。因此，删除了2011年的数据，并将起始时间设定为2012年1月1日。此外，通过数学方法将数据转换为小时消耗量，以提取特征并减少数据量。因此，预处理后的数据包含了2012年至2014年每个对象的每小时电力消耗。以下是处理后的数据。
