look ahead網(wǎng)絡(luò)解釋
1. 先行：針對(duì)以往群體智能聚類算法中分類錯(cuò)誤率較高、算法運(yùn)行時(shí)間較長等不足,提出記憶體方法和基于密度的先行(lookahead)策略. 用人工數(shù)據(jù)集和真實(shí)數(shù)據(jù)集進(jìn)行實(shí)驗(yàn),將實(shí)驗(yàn)結(jié)果進(jìn)行比較分析. 分析結(jié)果表明,基于密度的啟發(fā)性群體智能聚類算法能夠得到令人滿意的聚類結(jié)果,
2. 展望：關(guān)于公因子的問題,可以改寫算法(提取公因子),也可以通過展望(lookahead)更多符號(hào)的方法來解決. 但是因?yàn)閖avacc擴(kuò)展了經(jīng)典的BNF,因此它面臨更多的問題. 總之,當(dāng)在編譯時(shí)碰到?jīng)_突問題時(shí),就說到了一個(gè)choice point.
