    Neural object classification by pattern recognition of one dimensional data arrays which represent object information transformed by nonlinear functions.

    Published: November 06, 2018

    Pattern Groups of measurements or observations, defining points in an appropriate multidimensional space. Pattern recognition Aims to classify data (patterns) based on either a priori knowledge or on statistical information extracted from the patterns. My aim is to classify 2-dimensional objects with the help of manipulator and by the use of pattern recognition.
