查询词典 frequent

Sequential patterns base is applied to the algorithm, which stores all items, maximum frequent patterns and corresponding support counts in original database. Instead of remining impertinently, ISPBP updates the frequent items and patterns found previously by implicit merging and discovers new patterns by projection database.

算法引入序列数据库结构来存储从原始数据库中挖掘出的所有项、最大频繁模式以及它们的支持数，采用间接拼接方法，只需处理增量数据库，避免了对更新后数据库的重新计算。

For the problem of blocking inference channels in frequent pattern sharing, we propose to eliminate the related inference channels so that an attacker cannot derive if a sensitive pattern is frequent or not.

The expression of assembly structure based product structure labeled graph is proposed.The module partition method based on frequent subgraph mining is presented,and Apriori algorithm is applied to build the mapping between frequent subgrahs and product family modules.The structural correlation method of product family is presented,which includes the predefinition of the assembly structure of product family,the definition of the configuration relationships among producy family modules and the definition of the parameter correlations among producy family modules.

以成熟产品设计实例为分析对象，利用产品结构标号图描述其装配结构；提出基于频繁子图挖掘的产品族模块划分方法，建立频繁子图到产品族模块的映射关系；研究了产品族结构关联方法，包括产品族装配结构预定义、产品族配置关系定义和产品族参数关系定义。

Association rules mining is a very active field in data mining and there are many algorithms today. In this field, the most classical algorithm is Apriori put forward by Agrawal et. al and it is used widely. The paper analyzes the advantages an disadvantages of Apriori, AprioriTid and AprioriHybrid algorithm in mining association rules. To solve the bottle of AprioriHybrid algorithm, a Support-Matrix method to rapidly verify the 2-frequent itemsets is put forward. To accelerate the speed of verify the k-frequent itemsets, a simple and highly efficient method of minimizing the trade database is given. All these two methods improve the efficiency of AprioriHybrid method.

关联规则挖掘是数据挖掘中一个非常活跃的领域，当前有许多种算法，最经典并被广泛使用的是Agrawal等人提出的Apriori算法及其衍生算法，本文分析了Apriori，AprioriTid和AprioriHybrid算法的优缺点，针对AprioriHybrid算法的瓶颈提出一种使用支持度矩阵对频繁2项集快速验证的方法，并给出一种简单易行，而又高效的逐步缩减交易数据库的方法，加快对候选频繁k项集的验证速度，从而提高了AprioriHybrid算法的效率。

For patients with unprovoked PE who have a strong preference for less frequent INR testing to monitor their therapy, after the first 3 months of conventional-intensity anticoagulation (INR range, 2.0 to 3.0), we recommend low-intensity therapy (INR range, 1.5 to 1.9) with less frequent INR monitoring over stopping treatment (Grade 1A).

I use an example quoted by Hu Jiaqi:"It is reported that America separates the DNA of a kind of virus by making use of genetic technology and combines it with another kind of DNA. Finally, they get a kind of virulent biological agent called a "pyrotoxin". Someone discloses in private that 20 grams of such a kind of biological agent could result in the global death of 6 billion people due to infection."

我在这里例举胡家奇所引用过的例子："据报道，美国利用转基因技术，将一种病毒的DNA分离出来，与另外一种DNA进行结合，拼结成一种剧毒的"热毒素"生物战剂，且私下有人透露，这种生物战剂只需20克，就可以导致全球60亿人全部感染死亡。"
