Hypocenter location by pattern recognition
[1] A novel approach to hypocenter location is proposed on the basis the concept of pattern recognition. A new data misfit criterion for location is introduced which measures discrepancies between the observed arrival times of an event and those of ‘‘nearby’’ previous events. In the arrival pattern misfit measure, travel times predicted by an Earth model are effectively replaced by information ...
متن کاملLocation Independent Pattern Recognition using Genetic Programming
This paper describes an application of genetic programming. Programs able of recognizing a pattern independent of its location are evolved. Usually the evolution of programs is controlled primarily by the tness evaluation function. This paper demonstrates how genetic programming can be encouraged to evolve programs with properties not being explicitly considered in the tness measure like locati...
متن کاملAppraising Earthquake Hypocenter Location Errors: a Complete, Practical Approach for Single-event Locations by Gary
For conventional single-event, nonlinear, least-squares hypocentral estimates, I show that the total error is expressible as a linear combination of three terms: (1) measurement error; (2) modeling errors caused by inadequacy of the traveltime tables; and (3) a nonlinear term. Errors in calculating travel-time partial derivatives are shown to have no effect, provided a stable solution can be fo...
متن کاملPattern Recognition by Data Compression
Combinatorialpattern recognition is used for discrimination of handwritten signatures. The method partitions an input image into overlapping pieces. A piece is as large as possible under the constraints rst that it must have an identical copy at a smaller row number, second that the piece must have a xed width. The partitioning into pieces is performed according to a generalisation of the Lempe...
متن کاملPATTERN RECOGNITION BY MACHINE Oliver
Can a machine think? The answer to this old chestnut is certainly "yes": Computers have been made to play chess and checkers, to prove theorems, to solve intricate problems of strategy. Yet the intelligence implied by such activities has an elusive, unnatural quality. It is not based on any orderly development of cognitive skills. In particular, the machines are not well equipped to select from...
