Embodiment Construction
[0035] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions proposed in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0036] The text retrieval method of the embodiment of the present invention is based on the "adaptive mapping" algorithm. Referring to Figure 1, the "adaptive mapping" algorithm includes the following steps:
[0037] S102: Input the original data; the original data is in the form of a vector, and its dimension may be M;
[0038] S104: Determine the dimension of the target mapping space, that is, the dimension of the data to be reduced in dimension, which may be set as N;
[0039] S106: Determine the dimensionality reduction mapping relationship according to the dimensionality of the original data and the determined dimensionality of the target mapping space;
[0040] S108: According to the dimension reduction mapp...
