Zusammenfassung:The embodiment of the invention provides a data dimension reduction method and device, electronic equipment and a storage medium, and relates to the technical field of big data processing, and the method comprises the steps: obtaining index value sequences corresponding to a plurality of target indexes of a financial product; the index values are input into a first coding network for data dimension reduction, a first dimension reduction result of a first dimension is obtained, and the first dimension is determined according to the correlation degree of financial semantics of all the target indexes; the index value of the specified dimension in the first dimension reduction result is input into a second coding network for data dimension reduction, a second dimension reduction result of a second dimension is obtained, and the second dimension is determined according to the correlation degree of financial semantics of all dimensions in output data of the first coding sub-network; and combining the index values o
