摘要:
In a document classification device 100, a sample document extraction condition storage unit 160 stores sample document extraction conditions 160-1 set for each of classification categories for extracting partial text according to the classification categories from an input document 301 input by a document input unit 110. A document matching unit 120 matches the input document 301 against the sample document extraction conditions 160-1. Based on a result of matching by the document matching unit 120, a document extraction unit 130 extracts the partial text from the input document 301 according to the classification categories. A learning unit 140 performs predetermined machine learning using as a sample document the partial text extracted by the document extraction unit 120, and thereby generates classification rules 150-1.

摘要:
A data predicted value generating unit generates a predicted value (data predicted value) for original data intended to be encoded, based on a history of original data which is floating-point data. A data predicted value modifying unit adjusts a mantissa value of the data predicted value by aligning an exponent value of the data predicted value with an exponent value of the original data. A first residual generating unit generates a residual (first residual) between new original data and the data predicted value after being adjusted. A first residual predicted value generating unit generates a predicted value for the first residual (first residual predicted value), based on a history of first residuals. A second residual generating unit generates a residual (second residual) between the first residual and the first residual predicted value. A residual encoding unit generates encoded data by encoding the second residual.
