  1. Optimized association rules are permitted to contain uninstantiated attributes. the optimization procedure is to determine the instantiations such that some measures of the roles are maximized. this paper tries to maximize interest to find more interesting rules. on the other hand, the approach permits the optimized association rule to contain uninstantiated numeric attributes in both the antecedence and the consequence. a naive algorithm of finding such optimized rules can be got by a straightforward extension of the algorithm for only one numeric attribute. unfortunately, that results in a poor performance. a heuristic algorithm that finds the approximate optimal rules is proposed to improve the performance. the experiments with the synthetic data sets show the advantages of interest over confidence on finding interesting rules with two attributes. the experiments with real data set show the approximate linear scalability and good accuracy of the algorithm

    優化關聯規則允許在規則中包含未初始化的屬性.優化過程就是確定對這些屬性進行初始化，使得某些度量最大化.最大化興趣度因子用來發現更加有趣的規則;另一方面，允許優化規則在前提和結果中各包含一個未初始化的數值屬性.對那些處理一個數值屬性的演算法進行直接的擴展，可以得到一個發現這種優化規則的簡單演算法.然而這種方法的性能很差，因此，為了改善性能，提出一種啟發式方法，它發現的是近似最優的規則.在人造數據集上的實驗結果表明，當優化規則包含兩個數值屬性時，優化興趣度因子得到的規則比優化可信度得到的規則更有趣.在真實數據集上的實驗結果表明，該演算法具有近似線性的可擴展性和較好的精度

After 1989, the increase of demand slowed down and facing the complexion of low degree of industrial concentration of product market and financial strain of medi um and small - sized enterprises caused by the circulating trap of " credit squeeze - - - bad loan ", the advantageous enterprises " " wallow in money ", specifically, those listed companies that could finance from the stock market, began to take predatory pricing strategy in succession and tried to enlarge market share and obtain high return by squeezing medium and small - sized enterprises out of the market after 1998, the vicious circle of deflation and " credit grudging " of banks in product and credit markets, overcapacity, the difficulty of retreating of loss - incurring enterprises in some industries from the market for institutional reasons and over - competition in some industries, led to the incessant decrease of enterprises " global income, persistent increase of rate of debts and constant rise of ratio of bad assets of banks, which further intensified the vicious circle of deflation and " credit grudging " of banks

    如在改革開放初期，在產品市場需求旺盛和信貸市場預算軟約束的情況下，各類企業的最優決策就是採用高負債、高擴張的「負債的有限責任效應」策略來搶占市場並獲得高回報； 1989年以後，需求增速開始放緩，面臨產品市場產業集中度較低和信貸市場「信貸緊縮-不良貸款」循環陷阱導致的中小企業資金緊張的局面， 「錢袋鼓鼓」的優勢企業（尤其是那些可以通過股票市場融通資金的上市公司）紛紛採用掠奪性定價策略，試圖通過把中小企業擠出市場來擴大市場份額並獲得高收益； 1998年以後，產品市場和信貸市場形成了通貨緊縮和銀行「惜貸」惡性循環的狀況。產品市場上部分行業生產能力嚴重過剩，且由於體制等原因導致虧損企業無法退出，因此這些行業中出現了過度競爭的現象，企業總體收益的不斷下滑、負債率不斷提高以及銀行不良資產率的持續上升，又進一步加強了通貨緊縮和銀行「惜貸」的惡性循環。
