Please predict whether this patent is acceptable.PATENT ABSTRACT: A method of machine learning for generating a predictive model of a response characteristic based on historical data elements using a processor may include receiving historical data elements and historical values for the response characteristic related to uses of the historical data elements in web pages. A plurality of key-value pairs may be generated defining values of a plurality of predefined features representing properties of the historical data elements. Each of a plurality of n features may be represented by an axis in an n-dimensional space are extracted from the historical data elements. The extracted plurality of key-value pairs for each historical data element may be projected onto the n-dimensional space. The plurality of vectors may be input into a model generator to generate a predictive model predicting a value of the response characteristic for a new data element.
