In order to overcome problems arisen from the application of x fluorescence analysis into complex spectrum produced by archaeological ceramic fragments with multi-element, low content and thick ground, we have employed the artificial neural network into the research of x fluorescence archaeology and conducted three kinds of research works . as the first one, we have applied the linear olam network ( optimal linear association memory network ) and the non-linear bp network ( back-propagation network ) respectively to analyze the complex x fluorescence spectrum of archaeological samples, and taken both results of spectrum analysis to compare with each other . the second, the method of pattern recognition of bp network was tentatively used to perform intelligent identification of production places of these archaeological samples 針對(duì)科技考古中對(duì)大量考古陶片進(jìn)行產(chǎn)地研究時(shí)x熒光分析對(duì)多元素、低含量、厚基底考古陶片產(chǎn)生的復(fù)雜譜分析的問題,將人工神經(jīng)網(wǎng)絡(luò)引入x熒光考古中,進(jìn)行了三方面的研究工作:一是用線性olam網(wǎng)絡(luò)(最優(yōu)線性聯(lián)想網(wǎng)絡(luò))和非線性bp網(wǎng)絡(luò)(誤差反傳導(dǎo)網(wǎng)絡(luò))分別對(duì)考古樣品的x熒光復(fù)雜譜進(jìn)行解譜,并比較二者的解譜效果;二是用bp網(wǎng)絡(luò)模式識(shí)別方法對(duì)考古樣品的產(chǎn)地進(jìn)行智能識(shí)別;三是為了提高網(wǎng)絡(luò)運(yùn)算的可靠性和減小基體效應(yīng)及電噪聲的干擾和影響,研究并提出了三種網(wǎng)絡(luò)學(xué)習(xí)前的譜數(shù)據(jù)預(yù)處理方法。
