  • Patent number: 8326040
    Abstract: Various technologies and techniques are disclosed that improve handwriting recognition operations. Handwritten input is received in training mode and run through several base recognizers to generate several alternate lists. The alternate lists are unioned together into a combined alternate list. If the correct result is in the combined list, each correct/incorrect alternate pair is used to generate training patterns. The weights associated with the alternate pairs are stored. At runtime, the combined alternate list is generated just as training time. The trained comparator-net can be used to compare any two alternates in the combined list. A template matching base recognizer is used with one or more neural network base recognizers to improve recognition operations. The system provides comparator-net and reorder-net processes trained on print and cursive data, and ones that have been trained on cursive-only data. The respective comparator-net and reorder-net processes are used accordingly.

  • Patent number: 7865018
    Abstract: Handwriting recognition techniques employing a personalized handwriting recognition engine. The recognition techniques use examples of an individual's previous writing style to help recognize new pen input from that individual. The techniques also employ a shape trainer to select samples of an individual's handwriting that accurately represent the individual's writing style, for use as prototypes to recognize subsequent handwriting from the individual. The techniques also alternately or additionally employ an intelligent combiner to combine the recognition results from the personalized recognition engine and the conventional recognition engine (or engines). The combiner may use a comparative neural network to combine the recognition results from multiple recognition engines. The combiner alternately may use a rule-based system based on prior knowledge of different recognition engines.

  • Patent number: 7724957
    Abstract: Systems and methods that exploit unique properties of a language script (e.g., condition joining rules for Arabic language) to enable a two tier text recognition. In such two tier system, one tier can recognize predetermined groups of linked letters that are connected based on joining rules of a language associated with the text, and another tier dissects (and recognizes) such linked letters to respective constituent letters that form the predetermined group of linked letters. Various classifiers and artificial intelligence components can further facilitate text recognition at each level.

  • Patent number: 7715629
    Abstract: Techniques for processing handwriting input based upon a user's writing style. Some techniques employ the style in which the user writes a single character, while other techniques alternately or additionally employ a group of allographs that form a handwriting style. Some implementations of these techniques, such as those implemented in writing style analysis tool, analyze one or more characters written by a user to identify a community, such as a geographic region or cultural group, to which the user's handwriting style belongs. Other implementations analyze one or more characters of a user's handwriting in order to alternately or additionally categorize the user's handwriting into a particular handwriting style. The writing style analysis tool may then provide the user with a handwriting recognition application specifically configured for that user's personal handwriting style.

  • Patent number: 7646913
    Abstract: The claimed subject matter provides a system and/or a method that facilitates analyzing and/or recognizing a handwritten character. An interface component can receive at least one handwritten character. A personalization component can train a classifier based on an allograph related to a handwriting style to provide handwriting recognition for the at least one handwritten character. In addition, the personalization component can employ any suitable combiner to provide optimized recognition.

  • Patent number: 7593908
    Abstract: Systems and methods are provided for training neural networks and other systems with heterogeneous data. Heterogeneous data are partitioned into a number of data categories. A user or system may then assign an importance indication to each category as well as an order value which would affect training times and their distribution (higher order favoring larger categories and longer training times). Using those as input parameters, the ordered training generates a distribution of training iterations (across data categories) and a single training data stream so that the distribution of data samples in the stream is identical to the distribution of training iterations. Finally, the data steam is used to train a recognition system (e.g., an electronic ink recognition system).

  • Patent number: 7369702
    Abstract: Input handwritten characters are classified as print or cursive based upon numerical feature values calculated from the shape of an input character. The feature values are applied to inputs of an artificial neural network which outputs a probability of the input character being print or cursive. If a character is classified as print, it is analyzed by a print character recognizer. If a character is classified as cursive, it is analyzed using a cursive character recognizer. The cursive character recognizer compares the input character to multiple prototype characters using a Dynamic Time Warping (DTW) algorithm.

  • Patent number: 7302099
    Abstract: Ink strokes of cursive writing are segmented to make the cursive writing more like print writing, particularly with respect to the number of strokes of a character. A stroke-segmentation module first finds the local extrema points on a stroke of input ink. Then the local extrema points are stepped through, two (or three) at a time. The stroke-segmentation module may compare the three (or four) ink segments that are adjacent to the two (or three) local extrema points to a set of predefined stroke-segmentation patterns to find a closest matching pattern. Strokes are then segmented based on a stroke-segmentation rule that corresponds to the closest matching pattern. Additional stroke segmentation may be performed based on the change of curvature of the segmented ink strokes. Then, a character-recognition module performs character recognition processing by comparing the segmented ink strokes to prototype samples at least some of which have been similarly segmented.
