Sensor exploration and management through adaptive sensing framework
First Claim
1. A system for collecting data from a deployed sensor network and providing predictive analysis for use in system operations comprising:
- at least two sensors located in geospatially separate areas;
a communications means for transporting collected data from said sensors to a system server;
a memory storage unit within said server on which are stored software modules for tracking, activity evaluation, sensor management agent, sensor control, and issuing system alerts to users;
said software modules using statistical modeling means for predictive state management based upon a plurality of parameters to produce a probabilistic evaluation for an occurrence of event change in the modeled sensor data;
using said predicted probabilistic evaluation data to preferentially select portions of said collected sensor data for continued evaluation;
without human input, identify previously unknown events or objects within said collected sensor data and provide said information to a decision agent software process;
said software modules accepting feedback from said users to update a learning database for defining said preferentially selected sensor data within said system server;
issuing sensor control signals from said sensor management agent software module to said sensors located in geospatially separate areas to request additional sensor data collection, or to modify parameters for sensor data collection;
without human supervision, comparing said preferentially selected portions of collected sensor data to a predefined set of events and causing said decision agent process to issue said system alert to users when any of said predefined events is detected and a pre-set risk threshold is exceeded.

Abstract
The identification and tracking of objects from captured sensor data relies upon statistical modeling methods to sift through large data sets and identify items of interest to users of the system. Statistical modeling methods such as Hidden Markov Models in combination with particle analysis and Bayesian statistical analysis produce items of interest, identify them as objects, and present them to users of the system for identification feedback. The integration of a training component based upon the relative cost of sampling sensors for additional parameters, provides a system that can formulate and present policy decisions on what objects should be tracked, leading to an improvement in continuous data collection and tracking of identified objects within the sensor data set.
