The method of claim 1, wherein the generating comprises: determining a parameter value of the global shape parameter; determining a parameter vector of the selected training data using the determined parameter value; dividing the parameter vector into data sets; verifying whether a degree of separation between the data sets satisfies a predetermined condition; and storing division information on the generating of the clusters when the degree of separation satisfies the predetermined condition. 4. The method of claim 3, wherein the dividing of the parameter vector comprises: dividing the parameter vector into the data sets based on randomly determined threshold values, and wherein an arbitrary number of the threshold values are generated. 5. The method of claim 3, wherein the degree of separation is determined based on a mean and a standard deviation of each data set. 6. The method of claim 3, wherein the division information on the generating of the clusters comprises information on the global shape parameter used to generate the clusters and information on the threshold values used to divide the parameter vector into the data sets. 7. The method of claim 3, wherein, the degree of separation satisfies the predetermined condition when a currently determined degree of separation is greatest among degrees of separation determined based on global shape parameter. 8. The method of claim 1, wherein the classifying comprises: determining a feature value of the local shape feature; determining a feature vector of the training data from the cluster based on the determined feature value; dividing the feature vector into data sets; verifying whether an entropy determined based on the data sets satisfies a predetermined condition; and storing division information on the classifying of the training data from the cluster when the entropy satisfies the predetermined condition. 9. The method of claim 8, wherein the dividing of the feature vector comprises: dividing the feature vector into the data sets based on randomly determined threshold values; and wherein an arbitrary number of the threshold values are generated. 10. The method of claim 8, wherein the division information on the classifying of the training data from the cluster comprises information on the local shape feature used to classify the training data from the cluster, and information on the threshold values used to divide the feature vector into the data sets. 11. The method of claim 8, wherein, when a currently determined entropy is smallest among entropies determined based on local shape features, the verifying comprises determining that the entropy satisfies the predetermined condition. 12. A data recognizing method, the method comprising: reading input data; determining a cluster to which the input data belongs based on learned global shape parameter information; and determining a class of the input data based on the determined cluster and learned local shape feature information. 13. The method of claim 12, wherein the learned global shape parameter information is used to determine a global feature of the input data, and the learned local shape feature information is used to determine a local feature of the input data. 14. The method of claim 12, wherein the determining of the cluster comprises: determining a parameter value of the input data based on the learned global shape parameter information; and determining the cluster corresponding to the determined parameter value using information on a stored threshold value. 15. The method of claim 12, wherein the determining of the class comprises: loading at least one recognizer to classify data from the determined cluster; and estimating the class of the input data based on the recognizer and the local shape feature information. 16. The method of claim 15, wherein the estimating of the class comprises: determining a feature value of the input data based on the local shape feature nformation; and estimating the class of the input data based on the determined feature value and information on a threshold value stored in the recognizer. 17. A non-transitory computer-readable medium comprising instructions for a computer to perform the method of claim 1. 18. (canceled) 19. (canceled) 20. A data recognizer, comprising: at least one processor; and a memory having instructions stored thereon executed by the at least one processor to perform: input data; determining a cluster to which the input data belongs based on learned global shape parameter information; and determining a class of the input data based on the determined cluster and learned local shape feature information.
