Abstract

The Analyst Cueing method addresses the issues of locating desired targets of interest from among very large datasets in a timely and efficient manner. The combination of computer aided methods for classifying targets and cueing a prioritized list for an analyst produces a robust system for generalized human-guided data mining. Incorporating analyst feedback adaptively trains the computerized portion of the system in the identification and labeling of targets and regions of interest. This system dramatically improves analyst efficiency and effectiveness in processing data captured from a wide range of deployed sensor types.

Claims

1. A method for change detection of targets within regions of interest in a sensor derived data set comprising:

receiving a data set of sensor information collected in the field;

extracting features and regions of interest from within the sensor dataset;

constructing a classifier defined set of features;

building a separate data set containing identified and labeled targets;

generating a prioritization list of said identified and labeled targets;

presenting said prioritized list of identified and labeled targets to a human analyst; and

wherein the human analyst may input new labels and target identification to the prioritized list which is then incorporated into said data set containing identified and labeled targets, said data set then formatted and presented upon a display for use by the human analyst.

2. A method according to claim 1, wherein the sensors collecting data comprise an array of sensors deployed to collect samples from a defined area.

3. A method according to claim 1, further comprising:

said extraction of features and regions of interest is performed by a software module resident upon a server capable of network communications;

said software module comparing extracted features and regions of interest against a predefined set of interest criteria; and

wherein the server module provides a pre-screening function for all extracted data of interest.

4. A method according to claim 1, wherein said predefined interest criteria further comprise a defined set of features that form the basis data set of labels for all previously identified and selected targets.

5. A method according to claim 1, wherein the separate data set containing identified and labeled targets is separate from the basis data set of labels.

6. A method according to claim 1, wherein the separate data set containing identified and labeled targets includes labels generated by the server module without assistance from a human analyst.

7. A method according to claim 1, wherein said prioritized list is a combination of the basis data set of labeled targets and the separate data set containing labeled targets.

8. A method according to claim 1, wherein the human analyst provides feedback to the server module in a series of iterative steps that proceeds until all new data set information has been compared, identified, labeled and/or discarded.

9. A computer generated software product embodied within a storage medium for change detection of targets within regions of interest in a sensor derived data set comprising:

a server module operative to extract data fields from incoming data communications;

receiving a data set of sensor information collected in the field;

extracting features and regions of interest from within the sensor dataset;

constructing a classifier defined set of features;

building a separate data set containing identified and labeled targets;

generating a prioritization list of said identified and labeled targets;

presenting said prioritized list of identified and labeled targets to a human analyst; and

wherein the human analyst may input new labels and target identification to the prioritized list which is then incorporated into said data set containing identified and labeled targets, said data set then formatted and presented upon a display for use by the human analyst.

10. A method according to claim 9, wherein the sensors collecting data comprise an array of sensors deployed to collect samples from a defined area.

11. A method according to claim 9, further comprising:

said extraction of features and regions of interest is performed by a software module resident upon a server capable of network communications;

said software module comparing extracted features and regions of interest against a predefined set of interest criteria; and

wherein the server module provides a pre-screening function for all extracted data of interest.

12. A method according to claim 9, wherein said predefined interest criteria further comprise a defined set of features that form the basis data set of labels for all previously identified and selected targets.

13. A method according to claim 9, wherein the separate data set containing identified and labeled targets is separate from the basis data set of labels.

14. A method according to claim 9, wherein the separate data set containing identified and labeled targets includes labels generated by the server module without assistance from a human analyst.

15. A method according to claim 9, wherein said prioritized list is a combination of the basis data set of labeled targets and the separate data set containing labeled targets.

16. A method according to claim 9, wherein the human analyst provides feedback to the server module in a series of iterative steps that proceeds until all new data set information has been compared, identified, labeled, and/or discarded.
