RSW gun fault prediction benchmark data set

The resistance spot welding (RSW) welding gun fault prediction benchmark data set has 72 multivariate time series in the training set and 8 time series in the testing set. Each time series length 604800 sampled at 1 Hz with missing values and has 20 dimensions (c1-c19 and the error code). There are five classes of error codes: 'E01', 'E02', 'E03',' E04', and' 0'. '0 'means no error (in the proportion of 1:1:1:1 both the training set and the test set). We retain the missing value and the outliers of the welding gun time series for the potential of imputation research in the future.本数据集为电阻点焊（Resistance Spot Welding, RSW）焊枪故障预测基准数据集，其中训练集包含72组多元时间序列，测试集包含8组时间序列。每组时间序列采样频率为1 Hz，单组序列长度为604800个采样点，存在缺失值，共涵盖20个维度（包括c1至c19以及错误码）。错误码共分为5类：'E01'、'E02'、'E03'、'E04'与'0'，其中'0'代表无故障，训练集与测试集内各类别占比均为1:1:1:1。本数据集保留了焊枪时间序列中的缺失值与异常值，以供未来开展缺失值插补相关研究使用。
