Abstract

The invention includes methods for content preserving data synthesis. In one method, data is collected into a data domain. The data domain is decomposed into self-organizing parts. Each self-organizing part is described by a descriptor or algorithm. The method can be performed dynamically The algorithm used to describe each self-organizing part can be a weighted Voroni tessellation.

Claims

1. A method for organizing data, comprising:

(a) collecting data in a data domain;

(b) decomposing the data domain into self-organizing parts;

(c) describing each self-organizing part individually by a descriptor or algorithm;

(d) repeating steps (b) and (c) as the data domain grows.

2. The method of claim 1 wherein steps (a)-(c) are performed dynamically.

3. The method of claim 1 wherein steps (a)-(c) are performed in real-time.

4. The method of claim 1 wherein the data is engineering data.

5. The method of claim 1 wherein the data domain is at least one terabyte in size.

6. The method of claim 1 wherein the self-organizing parts preserve discontinuities in the data.

7. The method of claim 1 wherein the step of describing each self-organizing part is performed by applying weighted Voronoi tessellations.

8. The method of claim 6 wherein the data is associated with oil exploration and wherein the discontinuities are associated with cracks between seams in rock layers.

9. The method of claim 1 wherein the data is associated with engineering functions selected from the set comprising engineering design, engineering operations, and engineering maintenance.

10. The method of claim 1 wherein the data is associated with functions selected from set comprising real-time analysis of machine performance, real-time updates of digital components, onboard analysis support for diagnostics and repairs, real-time optimization of machine performance during operation in the field, control systems based on large scale data sets and physics based analysis, and rapid design cycles for product design and product improvement.

11. The method of claim 1 further comprising receiving a selection of variables to supply a framework and a selection of target variables or target relationships from an analyst.

12. The method of claim 11 further comprising evolving a structure of the data domain at least partially based on the selection of variables to supply a framework.

13. The method of claim 11 further comprising evolving a structure of the data domain at least partially based on the selection of the target variables or target relationships.

14. The method of claim 1 wherein the data is engineering data and the self-organized parts are described by physical relationships.

15. A computer-assisted method for organizing data within a data domain, comprising:

supplying variables to provide a framework based on a request to be answered;

selecting at least one target wherein the at least one target is a variable or relationship, the selecting based on the request to be answered;

decomposing the data domain into self-organizing parts based on the variables that provide the framework and the at least one target;

describing each of the self-organizing parts.

16. The computer-assisted method of claim 15 wherein each of the self-organizing parts is defined by a tessellation.

17. The computer-assisted method of claim 15 wherein each of the self-organizing parts is described by a weighted Voroni tessellation.

18. The computer-assisted method of claim 15 further comprising accessing data within one of the self-organizing parts to determine an answer to the request.
