Embodiment Construction
[0025] Embodiments of the present invention will be described below in conjunction with the accompanying drawings.
[0026] As attached to the manual figure 1 As shown, the present invention provides a neighbor storage method based on a data mapping algorithm. This scheme is mainly divided into three levels, which are: using spectral hash for hash mapping, data mapping algorithm, and construction of Chord. The specific implementation steps include the following:
[0027] Step 1. Using spectral hashing algorithm to hash map the high-dimensional data samples to obtain the k-dimensional binary hash code of each high-dimensional data item. The specific process is as follows:
[0028] The spectral hashing algorithm is to integrate the spectral analysis technology into the hash function, and use the constructed new hash function to process high-dimensional data. Spectral hashing needs to perform spectral analysis on high-dimensional data samples first, and then generate a hash fu...
