Method for enhancing a computer to estimate an uncertainty of an onset of a signal of interest in time-series noisy data
| DWPI Title: Method for enhancing computer to estimate uncertainty of onset of signal of interest, involves evaluating difference between combination, and deriving posteriori distribution for uncertainty of time at which onset occurs using processor |
| Abstract: A computer-implemented method of enhancing a computer to estimate an uncertainty of an onset of a signal of interest in time-series noisy data. A first mathematical model of first time series data that contains only noise is calculated. A second mathematical model of second time series data that contains the noise and an onset of a signal of interest in the second time series data is calculated. A difference is evaluated between a first combination, being the first mathematical model and the second mathematical model, and a second combination, being the first time series data and the second time series data, wherein evaluating is performed using a generalized entropy metric. A specific time when an onset of the signal of interest occurs is estimated from the difference. An “a posteriori” distribution is derived for an uncertainty of the specific time at which the onset occurs. |
| Use: Method for enhancing a computer to estimate uncertainty of an onset of a signal of interest in time-series noisy data (claimed). |
| Advantage: The method enables providing a seismic analysis framework using same data that is already collected and employs non-parametric modeling techniques to avoid strong distributional assumptions to extract arrival time information from the data in an effort to reduce frequency and extent of disagreement among analysts. |
| Novelty: The method (600) involves calculating (602) a first mathematical model of first time series data that contains only noise using a processor. A second mathematical model of second time series data that contains the noise and an onset of a signal of interest in the second time series data is calculated (604) using the processor. Difference between a combination is evaluated (606) using the processor. Specific time is estimated (608) from the difference using the processor when the onset of the signal of interest occurs. Posteriori distribution for uncertainty of the specific time at which the onset occurs is derived (610) using the processor. |
