摘要： PROBLEM TO BE SOLVED: To efficiently prepare a model expressing the relation between attributes by combining the automatic setting of conditions of model with the correction of conditions by a user, supporting the process of explanation parameter selection and introducing the knolwdge of the user. SOLUTION: A data storage means 101 stores the set of data composed of plural attributes, and an analytic means 102 analyzes the degree of relation between the attributes in the set of these data and finds the level of degree of relation between the attributes. Based on this analyzed result, a setting means 103 automatically sets the initial conditions of model. When the user corrects these set conditions, an estimating means 105 estimates the model on the set conditions. Then, an evaluating means 106 evaluates the estimated model, automatically sets the conditions of model according to the degree of relation between the attributes, displays these conditions for the user, simultaneously accepts the correction clue to the user and preserves the history of correction and by repeatedly performing the condition setting, estimation, evaluation and correction of model, the model is prepared.

摘要： PROBLEM TO BE SOLVED: To make prevention of visual change and resistance to image processing compatible by changing the values of contents, defining a data- changeable range a before and after change as a data-changeable range of values in embedding information, changing the values of contents within the data-changeable range and embedding information. SOLUTION: An image is inputted and stored in a storage device by input/ output processing 101. A medical filter or an image processing similar to it is applied to image data 102 and as a result, an image with different luminance but is visually the same as the image data 102 is obtained by a changeable range calculation processing 103. Next, the luminance before and after application of the image processing are stored for every pixel and data in the data- changeable range 104 is outputted by the changeable range calculation processing 103. Pixels the luminance of which are changed to specified values are selected among pixels of the image data 102 by an information embedding processing 105. Next, the information is embedded to each of the selected pixels by changing the luminance to a specified value to obtain information insertion image data 106.

摘要： PROBLEM TO BE SOLVED: To periodically generate a rule while operating respective elements without performing input operation and to display the time sequential change of the rule by inputting rule generation conditions and start conditions by a user. SOLUTION: The condition definition of rule generation is previously stored in a rule generation condition storage means 07 by an input means 10 and the rule generation condition to be started, time or time interval is stored from the input means 10 to a start condition storage means 06. On the basis of data in the start condition storage means 06, a data mining starting part 05 periodically starts a data mining executing part 03, performs rule generation, stores the result in a rule storage means 04 and sends it to a rule comparing part 08. The rule comparing part 08 compares the rule newly generated by the data mining executing part 03 with the rule in the past stored in the rule storage means 04 and the time sequential change of the generated rule is detected and displayed on a display means 09. Thus, the time sequential change of the rule can be detected.

摘要： PROBLEM TO BE SOLVED: To automatically monitor the large amount of time sequential data of many kinds by comparing an object time sequence for which object values are arranged corresponding to the generation time and a derivative time sequence generated based on it and judging the change of the object time sequence. SOLUTION: A data base 102 holds the object value (the measured value of a working dimension for instance) and an attribute value (the time of performing working for instance) accompanying the object value as a set. By a selection means 103, the set 110 of attribute sets is generated. The object values are summed up by a sum-up means 104 and the set 111 of the summed-up attribute sets is generated for the respective sets 110 of the attribute sets. A derivative time sequence generation means 105 performs a prescribed arithmetic operation to the object time sequence for which the summed-up attribute sets are arranged in the order of the generation time and generates the derivative time sequence 112. By a change judgement means 106, the object time sequence and the derivative time sequence are compared and the change is judged. A reporting means 107 reports the result of change judgement to a user 109.

摘要： PROBLEM TO BE SOLVED: To make prevention against visual variation and durability to an image process compatible by varying the value of image data, etc., that a human can not be aware of by using a medical filter, regarding the range between the values before and after the variation as a variable range of values of information embedding, and varying the data value of the image data within the variable range and embedding information. SOLUTION: Input and output 101 inputs and stores an image in a storage device. Variable range calculation 103 applies the medical filter or an image process similar to it to the image 102. Consequently, an image which is different in luminance from the image 102 and visually unchanged is obtained. Then the variable range calculation 103 stores luminance before and after the image process application as the variable range 104, pixel by pixel. Information embedding 105 selects pixels to be varies in luminance out of the pixels of the image 102, and varies the luminance to specific values to embed the information, thus obtaining an information inserted image 106. This image 106 is outputted to the outside through the input and output 101.

摘要： PROBLEM TO BE SOLVED: To enable a sound to be measured even in the case of the sound emitted from an observation target being small, or in the case of the background noise level being small, and reduce danger of passive detection by observing direct wave from a noise generating device generating white or colored noise having a continuous spectrum and a sound containing reflecting wave from the observation target. SOLUTION: A noise generating device 110 generates white or colored noise having no sharp spectrum peak in frequency. The colored noise is DA-convered by the use of a digital filter to obtain analog noise signal series, and it is amplified to generate noise by a piezoelectric element. In a wave receiving device 120, non-directional sound receiving elements are arranged, for example, into two-dimensional lattice, and reflecting wave from an observation target 140 is detected. A signal processing device 130 collects signals from the respective sound receiving elements, performs beam forming according to the azimuth, and computes the spectrum by Fourier transform. About all the azimuth to be intended to observe, information of the spectrum is obtained, and if necessary, anisotropy is detected and the azimuth form of the target is computed.
