Embodiment Construction
[0025] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, not to limit the present application.
[0026] Hash learning maps data into binary strings through machine learning mechanisms, which can significantly reduce data storage and communication overhead, thereby effectively improving the efficiency of the learning system. The purpose of hash learning is to learn the binary hash code representation of the data, so that the hash code retains the neighbor relationship in the original space as much as possible, that is, maintains the similarity. Specifically, each data point will be represented as a compact binary string code (hash code), and two similar points in the original space sho...
