Sample expansion method and device, electronic equipment and storage medium

The invention provides a sample expansion method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring a fitting curve of target data; determining activation energy of the target data based on the fitting curve, and generating an acceleration model of the target data based on the activation energy; determining a mean square error between the target data and the fitting curve; and generating an expansion sample of the target data based on the mean square error and the acceleration model. According to the method, the fitting curve of the target data is firstly obtained, then the activation energy of the target data is determined on the basis of the fitting curve, then the acceleration model of the target data is generated on the basis of the activation energy, and finally the expansion sample is generated on the basis of the mean square error between the target data and the fitting curve and the acceleration model. 本公开提供一种样本扩充方法、装置、电子设备及存储介质，包括：获取目标数据的拟合曲线；基于
