Abstract

The embodiment of the invention discloses a data processing method, device and equipment, which are used for carrying out dimensionality reduction on high-dimensionality load data of a user so as to solve the problem of dimensionality disasters. The method provided by the embodiment of the invention comprises the following steps: acquiring initial load data of a target user, wherein the initial load data comprises load data of an initial dimension; a target auto-encoder obtained through training of a plurality of training samples is obtained, and the target auto-encoder comprises an encoder composed of N convolution layers and M pooling layers; each training sample comprises historical load data of an initial dimension and historical load data of a target dimension, the initial dimension is greater than the target dimension, and the target auto-encoder stores a dimension reduction rule for reducing the initial dimension to the target dimension; and inputting the initial load data into the target auto-encoder, so that the target auto-encoder reduces the dimension of the load data of the initial dimension into the load data of the target dimension according to the dimension reduction rule.

Description

technical field [0001] The embodiments of the present application relate to the field of machine learning, and in particular, to a data processing method, apparatus, and device thereof. Background technique [0002] Load curve clustering is an important topic and useful tool in many fields of energy research, and it is also a research hotspot in power data mining. [0003] In load prediction, the load curve is normalized before clustering, and a general model that can be used to predict the load curve is established, so as to realize the load prediction. [0004] But due to the curse of dimensionality in load curves, it is difficult to build a general model that can accurately predict load curves under all conditions. Distance-based methods such as K-means clustering exhibit instability in high-dimensional data. While traditional dimensionality reduction methods such as principal component analysis (PCA) can be used to alleviate the curse of dimensionality, these methods c...
