基于ELM-AE的二进制非线性哈希算法
A Binary Nonlinear Hashing Algorithm with ELM Auto-encoders
摘要
Abstract
The field of Internet applications is so expandable because of the development of mobile Internet,social network and e-com-merce in the data information age of 21 century that the various types of data are in explosive growth,which make the traditional data a-nalysis ineffective. In order to effectively solve the problem of retrieval of image with large scale and meet the application requirements of large scale image database,a binary nonlinear hashing algorithm based on Extreme Learning Machine Auto-Encoders ( ELM-AE) is pro-posed. It optimizes the data sample by ELM-AE and raises the efficiency of image retrieval. Through binary hashing to implement the mapping from high-dimensional image data to low-dimensional binary space,the retrieval accuracy and efficiency are improved. In addi-tion,nonlinear retrieval problem is solved by nonlinear activation function. The experimental results show that the proposed algorithm a-chieves good retrieval efficiency and accuracy with good performance in operation time and other aspects.关键词
