2543 本文关注当前主要的极小碰集求解算法，简要介绍了它们的基本思想，从算法描述和实例比较了它们的异同和复杂性， This pa-per focuses on the current major algorithms for computing minimal hitting sets. First, the basic ideas of algorithms were briefly introduced. Then, the similarities and differences, and complexity of them were compared by simple algorithm de-scription and examples.
2544 并设计实现了一个统一的实验平台，测试并比较了它们的实际执行效率，为实际选择合适的算法提供了重要参考依据。 An integrated experimental platform was implemented for testing and comparing their time efficien-cy, which provides an important reference for the actual selection of an appropriate algorithm in practice.
2545 针对现存可用于时间序列的增量式模糊聚类算法往往需要设置多个控制参数的问题，本文提出了一种基于自适应增量学习的时间序列模糊聚类算法。 Existing incremental fuzzy clustering algorithms which can be used for time series often require setting multiple control parameters. To solve this problem, a fuzzy clustering algorithm of time series based on adaptive incremental learning is proposed.
2546 该算法首先继承上一次聚类得到的簇结构信息以初始化当前聚类进程， First, the cluster structure information obtained by the previous clustering process is inherited to initial-ize the current clustering process.
2547 然后在无需设置参数的情况下自适应地搜索当前数据块中的离群样本，并自动从离群样本创建新簇， Then, the outliers in current data block are adaptively searched without parameters, andnew clusters are automatically created from the outliers.
2548 最后检查空簇识别标识确定是否需要移除部分簇以保证后续聚类过程的效率。 Finally, an empty cluster flag is checked to determine if some clus-ters need to be removed to ensure the favorable efficiency of subsequent clustering.
2549 实验结果表明所提算法对等长和不等长时间序列均具有良好的聚类准确性及运行效率。 The experimental results show that the proposed algorithm has good clustering accuracy and efficiency for both equal-length and unequal-length time series.
2550 大数据时代迅速发展的同时，如何解决数据的版权保护、信息保存、叛逆溯源等安全问题，也变得越来越重要。 With the rapid development of big data, it becomes more and more important to effectively solve the problems of copyright protection of data, preservation of data information, traceability of data, etc.
2551 数据库水印技术是最有效的防护技术，其面临的最大挑战是如何在不影响用户使用的前提下嵌入水印，且保证在不影响水印信息提取的前提下抵挡各种常见的水印攻击。 Database watermark-ing is the most effective protection technique. The biggest challenge of this technology is how to carry out the embedded watermarking without affecting the data, and how to withstand the various attacks without affecting the extraction of wa-termark information.
2552 本文首先描述了数据库水印的基本概念和工作原理;然后，介绍了常见的数据库水印技术，并进行了分类; In this paper, we first describe the basic concepts and principles of database watermarking;Then, we introduce and classify common database watermarking techniques;
