Increasing device data confidence and operation via temporal and spatial analytics
One example method includes determining a spatial distribution of devices in a three dimensional physical environment, determining a polling frequency for each of the devices, receiving data generated by the devices, evaluating the data, and assigning a trust score to the data. The devices may take the form of respective sensors operable to sense a physical attribute of the three dimensional physical environment. A Fourier transform may be employed to determine the polling frequency.
1. A method, comprising:
determining a spatial distribution of devices in a three dimensional physical environment;
determining a polling frequency for each of the devices;
determining an optimal device count based on the polling frequency and based on a distance array of the devices indicating distances between the devices and a particular point or area in the three dimensional physical environment;
receiving data generated by one of the devices based on at least the optimal device count, and the data comprises data about a non-spatial physical attribute of the three dimensional physical environment;
evaluating the data; and
assigning a final trust score to the data, wherein the final trust score is determined by applying one or more measures to the data and each applied measure is associated with a respective incrementation amount to be applied to a previous trust score value of the data.
2. The method as recited in claim 1 , wherein one or more of the devices comprises a sensor that is operable to sense, and report on, the non-spatial physical attribute of the three dimensional physical environment, and the non-spatial physical attribute comprises one of: temperature; pressure; humidity; light; odor; or sound.
3. The method as recited in claim 1 , wherein the data is placed in an ensemble table, and the polling frequency is determined in part by applying a Fourier transform to a portion of the ensemble table.
4. The method as recited in claim 3 , wherein the ensemble table includes, for one or more of the devices, a set of one or more readings taken by that device for each of a plurality of different times.
5. The method as recited in claim 1 , wherein assignment of the final trust score comprises for each applied measure, generating a value for the previous trust score value between 0 and 1.
6. The method as recited in claim 5 , wherein the measures comprise any one or more of: a 3 sigma check; a polling frequency check; and, a device count check.
7. The method as recited in claim 1 , further comprising issuing a notification if an excessive number of devices is determined to be present in the three dimensional physical environment and/or if the polling frequency is determined to be excessive.
8. The method as recited in claim 1 , further comprising polling the devices at the polling frequency.
9. A non-transitory storage medium having stored therein instructions that are executable by one or more hardware processors to perform operations comprising:
determining a spatial distribution of devices in a three dimensional physical environment;
determining a polling frequency for each of the devices;
determining an optimal device count based on the polling frequency and based on a distance array of the devices indicating distances between the devices and a particular point or area in the three dimensional physical environment;
receiving data generated by one of the devices based on at least the optimal device count, and the data comprises data about a non-spatial physical attribute of the three dimensional physical environment;
evaluating the data; and
assigning a final trust score to the data, wherein the final trust score is determined by applying one or more measures to the data and each applied measure is associated with a respective incrementation amount to be applied to a previous trust score value of the data.
10. The non-transitory storage medium as recited in claim 9 , wherein one or more of the devices comprises a sensor that is operable to sense, and report on, the non-spatial physical attribute of the three dimensional physical environment, and the non-spatial physical attribute comprises one of: temperature; pressure; humidity; light; odor; or sound.
11. The non-transitory storage medium as recited in claim 9 , wherein the data is placed in an ensemble table, and the polling frequency is determined in part by applying a Fourier transform to a portion of the ensemble table.
12. The non-transitory storage medium as recited in claim 11 , wherein the ensemble table includes, for one or more of the devices, a set of one or more readings taken by that device for each of a plurality of different times.
13. The non-transitory storage medium as recited in claim 9 , wherein assignment of the final trust score comprises for each applied measure, generating a value for the previous trust score value between 0 and 1.
14. The non-transitory storage medium as recited in claim 13 , wherein the measures comprise any one or more of: a 3 sigma check; a polling frequency check; and, a device count check.
15. The non-transitory storage medium as recited in claim 9 , wherein the operations further comprise issuing a notification if a number of devices present in the three dimensional physical environment is determined to be less than an optimal number and/or if the polling frequency is determined to fall below an optimum frequency.
16. The non-transitory storage medium as recited in claim 9 , wherein the operations further comprising polling the devices at the polling frequency.
