Method and apparatus for priority based data processing

A method of processing data using a data processing apparatus that has one or more control circuits, comprising the steps performed by the one or more control circuits of the data processing apparatus of:

• preparing a plurality of data, each data having a plurality of candidate values, an importance value and an identifier, and a priority list for setting a processing order for each data;
• performing a processing for one of data that has a highest priority in the priority list and is indicated by the corresponding identifier, wherein a statistic of the candidate values that refer mean or median for each data is used as a representative value of the data;
• updating at least one of data whose value is changed into a new value by the processing, wherein the new value replaces one of the corresponding candidate values that is farthest from the new value;
• computing the importance value of each updated data as a function of the corresponding candidate values that refer magnitude of variation;
• determining the priority list in accordance with a magnitude of importance based on the computed importance value;
• and
• repeating the steps of performing, updating, computing and determining until termination condition is reached.

A recording medium recording a computer-readable program, wherein

• the computer-readable program when executed causes a computer to perform the steps of:
• preparing a plurality of data, each data having a plurality of candidate values, an importance value and an identifier, and a priority list for setting a processing order for the plurality of data;
• processing for one of data that has a highest priority in the priority list and is indicated by the corresponding identifier, wherein a statistic of the candidate values for each data is used as a representative value of the data;
• updating at least one of data whose value is changed into a new value by the processing, wherein the new value replaces one of the corresponding candidate values that is farthest from the new value;
• computing the importance value of each updated data as a function of the corresponding candidate values that refer magnitude of variation;
• and
• determining the priority list in accordance with a magnitude of importance based on the computed importance value;
• and
• the computer-readable program when executed causes the computer to perform another step of repeating the steps of processing, updating, computing and determining until termination condition is reached.
