This paper presents a novel algorithm of hiding
secret messages by applying mathematical lemmas and
information theory. The proposed algorithm can hide more
information with acceptable embedded rate and achieves
requirements of information hiding algorithm and simply
information extracting. The main idea is applying modern
algebra to solve the information hiding problem in multimedia.
In order to prevent some attacks on stganography, hidden
initial bits of image data pixels are chosen randomly. The
extracted information are achieved without the reference of the
original image and extracted keys. The experiment results
show that our approach is effective and reliable.

bpdetail
严格按照BP网络计算公式来设计的一个matlab程序,对BP网络进行了优化设计
优化1：设计了yyy，即在o(k)计算公式时，当网络进入平坦区时(<0.0001)学习率加大，出来后学习率又还原
优化2：v(i,j)=v(i,j)+deltv(i,j)+a*dv(i,j) (BP network in strict accordance with the formula to design a matlab program, the optimized BP network design optimization 1: Design of the yyy, that is, o (k) formula, when the network into the flat areas (< 0.0001) increase learning rate large, after the optimization of learning rate reduction 2: v (i, j) = v (i, j)+ deltv (i, j)+ a* dv (i, j) )

GA
说明： 遗传算法（Genetic Algorithm）是模拟达尔文生物进化论的自然选择和遗传学机理的生物进化过程的计算模型，是一种通过模拟自然进化过程搜索最优解的方法，它最初由美国Michigan大学J.Holland教授于1975年首先提出来的，并出版了颇有影响的专著《Adaptation in Natural and Artificial Systems》，GA这个名称才逐渐为人所知，J.Holland教授所提出的GA通常为简单遗传算法（SGA）。(a genetic algorithm (GA) is a search heuristic that mimics the process of natural evolution. This heuristic is routinely used to generate useful solutions to optimization and search problems. Genetic algorithms belong to the larger class of evolutionary algorithms (EA), which generate solutions to optimization problems using techniques inspired by natural evolution, such as inheritance, mutation, selection, and crossover.)
