| 摘 要： | 为了科学地评定西藏引进甘薯品种的生产价值,利用加速遗传算法的投影寻踪模型,以解决果实品质质量高低的判定问题,最大限度避免了权重矩阵取值的人为干扰.结果表明:YS-8号综合投影值最大(1.5186),最适合在西藏地区栽培.采用投影寻踪法来确定权重,减小了人为因素的干扰,分析结果更加科学、准确.

| Abstract: | In order to assess the production values of sweet-potato introduced in Tibet scientifically,projection pursuit classification model based on RAGA was applied to the assessment on its projection direction was optimized and high-dimension data were converted into low-dimension space with PPC,value of projection indexes could was obtained.The results showed that comprehensive values of projection(1.5186)was biggest for YS-8 among these species.Based on these projection function values,subjective impact on weig... |
