From complexity science to large data technology Huang Hinglong complexity science and large data technology is a new science and new technology, which happened before and after 21st century, but also the scientific revolution and technological revolution occurred at the turn of the century. It is the scientific expression and technology realization of system thought respectively. From the rise of complexity science to the advent of large data age is a historical necessity, because the complexity of science for the birth of large data technology has laid a solid scientific foundation, and large data technology is the complexity of the scientific concept of the continuation and technical ...

Research and realization of large data management oriented to the field of Astronomy Harbin Institute of Technology Yao Hua This article will optimize the database performance of Oracle's real application cluster, testing to see if the existing Oracle real application cluster meets the needs of the project. In addition, this article will compare the performance of query statements in Oracle's real application cluster and other database management systems in the same situation. This article will also be tested on the scalability of Oracle's real application cluster to see if Oracle's real application cluster can support adding, expanding clusters to ...

A large data resource description model supporting efficient query retrieval Zhang Wenji Xianglenzhi Wangxiaofang The problem of large data resource description model which can not support efficient query retrieval in the form of a unified query interface, by extending the trace attribute of large data partition management model, the extension function is introduced, In order to support the construction of differentiated large data information resource organization pattern. On this basis, the inverted retrieval mode which supports high efficient retrieval of large data resources is given, and it is proved that it is much more efficient than traversal retrieval mode and hierarchical retrieval mode. At the same time, the unified query mechanism in dialect mode is given. At present, large data resources are traced ...

Similarity Chinese character recognition based on deep neural network in large data Charles Tau Zhang Shuye Jin Lianwen The traditional handwritten Chinese character recognition system (SHCCR) is limited by the feature extraction method, and a deep neural network (DNN) is used to identify the automatic learning of similar Chinese characters. This paper introduces the method of similar character set generation and the specific structure of deep neural network for similar Chinese character recognition, and studies the influence of different training data scale on recognition performance. Experiments show that DNN can effectively carry out feature learning, avoid the lack of artificial design features, and traditional based on gradient features ...

User anonymity method for large-data-oriented personalized retrieval Kanghaiyan Xiong Li, a method of anonymous user's interest model based on the combination of difference privacy and p-link technology, is proposed to solve the contradiction between the potential privacy security of personalized retrieval technology in large data and enhance the performance of personalized information retrieval. First, the user's quasi-identifier generalization and add noise to meet the difference privacy protection requirements, maximize the accuracy of the query in the statistical database, while minimizing the probability of identifying individuals and attributes, second, based on the similarity between users ' interests to the micro-poly to the full ...
