Embodiment Construction

[0030] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0031] Before introducing the exploratory high-dimensional data visualization device and method, a brief introduction to the current data processing methods is given.

[0032] High-dimensional data refers to data objects with multiple attributes, where the number of attributes is not clearly defined and generally depends on specific tasks. High-dimensionality is the inherent structural property of big data, and a large number of big data analysis tasks are related to high-dimensional data. Whether it is abstract scientific data ...

Abstract

The invention discloses an exploratory high-dimensional data visualization device and method. The device comprises a data import module, a data preprocessing module, an exploratory data analysis module and a visual display module, wherein data import module is used for connecting and selecting a corresponding selection or processing engine according to at least one data source, so as to carry outlinking and import source data; the data preprocessing module is used for cleaning the imported source data, and carrying out recognition, dimension division and measurement operations on a processeddata system, so as to obtain a dimension and a measurement label; the exploratory data analysis module is used for converting a dragging operation for the dimension and the measurement label into query for a database, and changing a mapping relationship between high-dimensional data object and visual spaces through a data conversion model, so as to visualize high-dimensional data; and the visual display module is used for generating a plurality of charts after the exploratory data analysis, and displaying the plurality of charts by adoption of an interactive analysis instrument panel or visualscreen. The device provides a plurality of visual high-dimensional data layout methods, so that the problem that data dimensions are limited and cannot be displayed is solved.

Description

technical field [0001] The invention relates to the technical field of data visualization, in particular to an exploratory high-dimensional data visualization device and method. Background technique [0002] Related technologies disclose an HTML5-based data visualization system and method. The system includes a data push and report module, which is used to make statistics on specified types of data, and provides a data report function, and uploads the statistical data to the collection and release module; the collection and release module is used to perform data processing on the data reported by the data push module Model conversion, and send the converted data to the data update push module; the data update push module is used to translate the converted data sent by the collection release module into an internal graphic display instruction, and push the internal graphic display instruction to the display module; a display module, configured to perform drawing and display ...
