1. A method of obtaining and analyzing information to determine an estimated state of a real world, the method comprising:

  • obtaining, by a processor in communication with a plurality of sources, first information from a first source of the plurality of sources, the first information being potentially indicative of a first state of the real world and a second state of the real world;

    determining, by the processor, that the estimated state is the first state if the first information exceeds a first decision threshold;

    determining, by the processor, that the estimated state is the second state if the first information exceeds a second decision threshold;

    obtaining, by the processor, second information from a second source of the plurality of sources if the first information does not exceed the first decision threshold and does not exceed the second decision threshold, the obtaining of the second information including;

    determining, by the processor, whether the second source includes information that is relevant to the estimated state based on a divergence between (i) a joint density of the second information and the estimated state and (ii) the product of the densities of the second information and the estimated state, the determined divergence resulting in a relevant score;

    determining, by the processor, whether the second source includes information that is redundant with the first information based on a divergence between (i) a joint density of the second information and the first information and (ii) the product of the densities of the second information and the first information, the determined divergence resulting in a redundant score; and

    determining, by the processor, whether the second source includes information that is more relevant and less redundant than other sources of the plurality of sources by (i) for each source, subtracting from the relevant score corresponding to the source, the redundant score corresponding to the source and a cost of obtaining the information from the source, resulting in an overall score for each source, and (ii) selecting the second source if the overall score for the second source is greater than each overall score of the other sources of the plurality of sources;

    determining, by the processor, whether the estimated state is the first state or the second state based on whether the first information and the second information together exceeds the first decision threshold or the second decision threshold, improving performance of the processor by reducing time consumed for determining whether the estimated state is the first state or the second state; and

    generating a notification based on the estimated state determination.
