    但粒子群算法仍存在如下不足:首先在多峰的情況下,粒子群有可能錯(cuò)過(guò)全局最優(yōu)解,遠(yuǎn)離最優(yōu)解的空間,最終得到局部最優(yōu)解;其次在算法收斂的情況下,由于所有的粒子都向最優(yōu)解的方向群游,所有的粒子趨向同一,失去了粒子間解的多樣性,使得后期的收斂速度明顯變慢,同時(shí)算法收斂到一定精度時(shí),算法無(wú)法繼續(xù)優(yōu)化,本文對(duì)原始粒子群算法提出了二點(diǎn)改進(jìn)方案: 1 .算法迭代到一定代數(shù)后,把此時(shí)找到的全局最優(yōu)解當(dāng)作速度更新公式的另一參數(shù)(本文稱之為階段最優(yōu)解)再進(jìn)行迭代; 2 .每次迭代過(guò)程中除最優(yōu)解以外的每個(gè)粒子都有一定概率“變異”到一個(gè)步長(zhǎng)以外的區(qū)域,其中“變異”的粒子在每一維上都隨機(jī)生成一個(gè)步長(zhǎng)。
  13. This algorithm adopts a middle ground between centroid - base and all - points - based approaches . instead of using a single centroid or all points to represent a cluster , a fixed number of representative points in space are chosen , these points represent and capture the geometry and shape of the cluster . in addition . the representative points of a cluster are generated by first selecting well - scattered objects for the cluster and then " shrinking " or moving them toward the cluster center by a specified fraction , or shrinking factor . the shrinking helps dampen the effects of outliers . therefore , cure is more robust to outliers
    該算法選擇基于質(zhì)心利基于代表對(duì)象方法之間的中間策略,它不用單個(gè)質(zhì)心或簇中全部對(duì)象米代表一個(gè)簇,而是選擇數(shù)據(jù)空間中定數(shù)目的只有代表性的點(diǎn),這些點(diǎn)代表和捕捉到了簇的形狀。此外,由于引入了收縮因子使代表點(diǎn)向簇小心“收縮”而使該算法能夠較好地消除孤立點(diǎn)的影響,在處理孤立點(diǎn)上也更加健壯。
