  • Publication number: 20230252067
    Abstract: A computer-implemented method, a computer program product, and a computer system for ranking explanatory variables in multivariate analysis. A computer system extracts words from documents related to categories, creates a histogram of the words in each category, and selects top words in each histogram, where the top words are used as representing words in each category. A computer system generates respective feature vectors of explanatory variable candidates and a feature vector of an objective variable, where a feature vector of a corresponding variable includes elements corresponding to respective ones of the categories and a value of element indicates whether a name of the corresponding variable is included in the top words. A computer system calculates cosine similarity between each of the respective feature vectors of the explanatory variable candidates and the feature vector of the objective variable. A computer system ranks the explanatory variable candidates, based on the cosine similarity.

  • Patent number: 10831561
    Abstract: A technique of operating a system is provided that processes data with one or more data processing modules provided in parallel. A synchronization token is input into at least one data processing module that is in an operational state from the one or more data processing modules provided in parallel, in response to a request to change allocation of the data. The allocation of the data is changed to the one or more data processing modules provided in parallel, after the synchronization token is input. In response to the synchronization token having arrived at a data processing module at a later stage, the at least one data processing module, that stopped the processing, starts processing data after the synchronization token is input to the at least one data processing module.
