发明名称 METHODS AND APPARATUS TO CORRECT SEGMENTATION ERRORS
摘要 Methods, apparatus, systems and articles of manufacture are disclosed to correct segmentation errors. An example disclosed method includes identifying, with a processor, a segment group comprising observation data associated with two or more segments, respective ones of the two or more segments having a similar first characteristic and a dissimilar second characteristic, identifying first portions of the observation data having errors, generating a first matrix of binary indicators associated with the observation data, the binary indicators associating the first portions of the observation data with a first correction factor, and generating a value for the first correction factor by minimizing a residual sum of squares of the segment group observation data associated with the first matrix of binary indicators.

主权项 1. A method to correct a misclassification error in segment data, comprising: identifying, with a processor, a segment group comprising observation data associated with two or more segments, respective ones of the two or more segments exhibiting a shared behavior characteristic and a dissimilar classification characteristic; identifying first portions of the observation data exhibiting errors; generating a first matrix of binary indicators associated with the observation data, the binary indicators associating the first portions of the observation data with a first correction factor; generating a value for the first correction factor by minimizing a residual sum of squares of the segment group observation data associated with the first matrix of binary indicators; and correcting the misclassification error by applying the first correction factor to the observation data based on the first matrix of binary indicators.
