Embodiment Construction
[0034] In order to make the purpose, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0035] Please refer to figure 1 , an embodiment of the present invention provides a multivariate geochemical anomaly identification method based on spatially constrained multi-autoencoders, comprising the following steps:
[0036] Step 1. Data clustering, that is, generating multiple sample groups by normalizing and clustering the diversified sample data;
[0037] In this embodiment, for Cu-Zn-Mn-Pb-Fe 2 o 3 Geochemical sample data (such as figure 2 shown) to perform normalization and clustering, and analyze the effect of different clustering factors (including cluster number, clustering method, similarity measurement method) on Cu-Zn-Mn-Pb-Fe 2 o 3 The influence of the clustering results of the geochemical prospecting sample data, check whether th...
