User data deletion method and device and electronic equipment

The embodiment of the invention provides a user data deletion method and device and electronic equipment. In the user data deletion method, after a server obtains a request for deleting user data, the user data corresponding to a user identifier carried in the request is searched for in first training data; if the user data corresponding to the user identifier is found, the found user data is deleted from the first training data, and a machine learning model is re-trained by using second training data obtained after the user data is deleted, therefore, the data of the specified user can be deleted from the training data and the generated machine learning model, the compliance requirement is met, and a new machine learning model can be retrained and published. 本说明书实施例提出了一种用户数据的删除方法、装置和电子设备，其中，上述用户数据的删除方法中，服务器获取删除用户数据的请求之后，在第一训练数据中查找上述请求中携带的用户标识所对应的用户数据，如果查找到上述用户标识对应的用户数据，则从上述第一训练数据中删除查找到的用户数据，并利用删除上述用户数据之后的第二训练数据，重新训练机器学习模型，从而可以实现从训练数据和生成的机器学习模型中删除指定用户的数据，满足合规要求，还可以重新训练并发布新的机器学习模型。
