Problems solved by technology

[0003] In order to obtain potential knowledge from massive amounts of information, a variety of systems or related practical tools for big data mining have emerged as the times require, realizing the integration of various technologies for big data from storage, calculation to visualization, etc., reducing the impact of big data to a certain extent. The technical threshold of mining modeling, but the following problems still exist in the existing technology: First, the modeling strategy is single, and the existing tools usually provide several big data mining templates to assist the development, the applicable business scenarios are limited, and the expansion development requires operators Have high professional knowledge; second, the modeling efficiency is low, because data modeling is a process of repeated iterative optimization, in order to test the correctness of the mining steps and the effectiveness of the mining effect, it is necessary to continuously perform calculation operations. In the scenario, the huge time cost is bound to be introduced

Embodiment 1

[0046] see image 3 , this implementation takes the principal component analysis of big data as an example to describe the intelligent modeling method of this system and the interaction relationship of each module.

[0047] (1) Add start and finish to identify the start and end of the modeling process. Each link is called a process node, and the data conversion node is also called an operator node.

[0048] (2) Add a data source, automatically trigger the metadata collection module, generate data source metadata, and mark the metadata type as "exampleSet". Some metadata are shown in the table below.

[0049] name Types of Role scope level string label [low,middle,high] factor_1 float regular [-∞,+∞] factor_2 float regular [-∞,+∞] factor_3 float regular [-∞,+∞] factor_4 float regular [-∞,+∞]

[0050] It can be seen from the table that the "name" in the metadata corresponds to the field name in the real data...

Embodiment 2

[0058] see Figure 4 , this implementation takes big data regression prediction based on neural network as an example to describe the complete intelligent data modeling process.

[0059] (1) Add "Start", "Complete", and "Data Source" nodes, and generate data source metadata through the metadata collection module as follows:

[0060] name Types of Role scope value float regular [-∞,+∞] factor_1 float regular [-∞,+∞] factor_2 float regular [-∞,+∞] factor_3 float regular [-∞,+∞]

[0061] (2) Add the "Data Selection" node, and select the factor_1~factor_2 fields as the modeling features. The Data Selection node outputs metadata as follows:

[0062] name Types of Role scope value float regular [-∞,+∞] factor_1 float regular [-∞,+∞] factor_2 float regular [-∞,+∞]

[0063] (3) Add a "Normalization" node to perform normalization operations on the factor_1~factor_3 fields. I...

Abstract

The invention discloses a big data intelligent modeling system and a method based on dynamic metadata. The system comprises a metadata acquisition module, a metadata algorithm library module, an abnormity detection module, a visualization module and a big data engine module. The method has the beneficial effects that (1) an intelligent modeling strategy based on metadata is provided, the whole data mining conversion process is simulated on the premise that actual data does not need to be loaded and even a big data mining engine does not need to be started, an output result of a current computing node is estimated in real time, modeling operation of an operator is assisted, and the technical threshold of big data modeling is reduced; and (2) an abnormity detection mechanism is further developed based on metadata, real data is replaced by the metadata, and matching detection is performed on data transmission forms and contents between upper and lower nodes, so that the method has the advantages of good real-time performance and high reliability compared with inspection of a big data set, thereby realizing real-time early warning of wrong process connection and improving the modelingefficiency.
