Patent ID: 7382921

Claim:
A method for creating character model graphs for an on-line recognizer of handwritten text, the method comprising: generating character model graphs from typical shapes of characters, the character model graphs having a set of adjustable parameters; recognizing sample words in a work set using the character model graphs; evaluating a recognition error for a sample word; calculating a gradient of the recognition error; adjusting the adjustable parameters of the character model graphs to provide an updated set of the adjustable parameters, based on at least one of the recognition error and the gradient of the recognition error; recognizing test words in a test set using character model graphs with the updated set of adjustable parameters; calculating a correct recognition value for the test set when using the model graphs with the updated set of adjustable parameters; iterating the above sequence of acts until the correct recognition value reaches an optimum value; and selecting the updated set of adjustable parameters yielding the correct recognition value having the optimum value as the set of adjustable parameters to be used in character model graphs.
