Consider the ways in which simultaneous display of multi-color video display multiple graphs of measurement data, each of which are in the form of some bands of the color spectrum, the selected color scale which corresponds to a particular characteristic of the signal measured parameter value changing in time. We present methods offer different solutions for the transition from traditional forms of presentation of information (the current values of the performance parameter measurement information) in the form of graphs, to the alternative form - titokowaru description of the condition of the object of research. When the research object is a dynamic object, and forms (original and proposed) are functions of time, i.e., dependent on the temporal characteristics.

However, for visualization and analysis (diagnosis, detection, monitoring, identificare suitable. For this class of objects is important to seek the unknown dependency changes of the investigated characteristics are not temporary, but on other variables, such as spatial coordinates. While the characteristics studied are typically stationary or quasi-stationary characteristics. Very often the task of this class occur in the allocation of anomalies in geological and geophysical data, in medical diagnosis, the assessment of the environmental situation, the analysis of the economic situation, etc.,

The closest in technical essence is the way to rapid dynamic state analysis of multivariate objects (RF Patent for invention RU # 2134897, C1, 20.08.1999.). The method allows to evaluate the magnitude and nature of the integral changes the state of an object across many of the observed measurement parameters.

The main disadvantage of this method is the inability to analyze the States of objects out of the time coordinate changes of measurement parameters. In other words, the method does not provide an assessment of the size and nature of the state changes of the investigated multi-parameter object depending on other (non-temporal) characteristics, such as Prosti measuring parameters (anomalies) on a set of experimental data (array of measurement options), providing estimates of the magnitude and spatial coordinates distribution anomalies, reducing labor costs in the preparation and formation of the matrix of experimental data, enhancing the visibility of the view data.

The goal achieved by implementation of the proposed method visual representation and analysis of abnormal values of the measurement parameters of the multidimensional object or process, the essence of which is to transform the results of the evaluation values of the measurement parameters of the object or process relevant information Cvetkovi signals of the visible spectrum, in the view of information Cvetkovi signals in the form of Cvetkovi matrix-histogram and displayed on a video monitor screen. As a measure or standard of measurement (estimation) of the anomalous values measurement parameter using the minimum, average (arithmetic mean, weighted, quadratic, exponential, etc.), average (expectation, variance) or background values.

The choice of the measurement parameters and the above-mentioned measures of abnormal values is carried out by the expert analyst, as the results of the evaluation of abnormal values of the measurement pairs and (degree of magnification) changes in selected measures the conversion operation is carried out by formation of the corresponding information tsvetkovogo signal depending on the results of the evaluation of abnormal values of the measurement parameters and the spatial coordinates of the measurements represent information Cvetkovi signals through Cvetkovi matrix-histogram whose rows correspond to the relative values of the results of the evaluation of abnormal values of the measurement parameters, columns - spatial coordinate their measurement, color matrix cells - identified classes of anomalous values of the measurement parameters, display information Cvetkovi signals for analysis on any physical media, including paper, screen, screen, video projection equipment. For each spatial coordinates of the measurement calculates the relative magnitude of the measurement parameters that are included in the appropriate class of anomalous values of the measurement parameters, visually on the extreme values, mind and character Cvetkovi image histograms anomalous values of the measurement parameters define the coordinates of the sources of the anomalies multidimensional objresult his average, the average or background values, as the results of the evaluation of abnormal values of the measurement parameters used classes of anomalous values of these parameters corresponding to the different sign of the multiplicity of the changes mentioned measures, representing positive and negative anomalous values of the measurement parameters of the multidimensional object or process.

Let multidimensional object of the study are presented in the form of a finite set M of experimental data. Traditionally such data for complex objects are multidimensional arrays of information, the analysis of which causes certain difficulties.

One of the main goals of the analysis is the localization of anomalies that characterize a particular (critical, unusual, atypical, abnormal, etc.,) state of the investigated object and / or the external environment.

Under the anomaly is traditionally understood as a deviation from the norm, from the General law. Accordingly, under the abnormal condition of the object to understand his condition, which is characterized by the anomaly. The sources of the anomalies, and hence the purpose of localization of anomalies can be very different. For example, for geological and geophysical objects source anomalies m and (interference). In the first case, the localization of anomalies (anomalous values of the experimental data is the Foundation on which is based the search for mineral deposits. In the second case, the goal of localization is suppressed (exception) random noise. In ecology the source of the anomalies can be deviations in the content of various harmful chemicals in the environment. An important task of environmental monitoring is to identify the sources and areas of contamination of the natural environment.

Clarify the concept of anomalies. We believe that all necessary information about the state of the object and the environment contained in the original set (matrix) of the experimental data. We assume that the results of some observations on the research object is represented in a data matrix whose rows correspond to different measurement parameters, and columns specific values (scalars) that describes the values of these parameters depending on the spatial coordinates. Let the studied object or process is characterized by some finite number n of measurement parameters with the number m of the specific values of each of them. Then the source data set on the volume is bringing a single j-e measurement (observation, test) for the i-th measurement parameter or by the i-th sample (realization).

For the analysis of large amounts of measurement data multidimensional objects, which, as a rule, it is in a granular form, a person (the expert analyst) uses this technique as a generalization. We propose the following approach.

The well-known concept of measure (benchmark) is invariant to the object of measurement. In other words, the properties of the test object does not depend on the adopted measure their properties. This state of Affairs from the point of view of the analysis of the properties of the investigated multidimensional object is not always easy and in some cases can lead to rapid (exponential) growth of the array measurement data. The way out of this situation is the transition to other more common measurement scale, i.e., the change of measure. More interesting results can be obtained using the measure, which carries information about the state of the object or process. We introduce the notion of a measure or a standard of measurement (estimation) of the anomalous values of the measuring multidimensional parameter object or process.

We believe that the value of the element asijmatrix (1) is determined by rassmatri. Each element of aijdepending on the state of the object, obtaining conditions (measurement) of this element, etc. can be normal (within the tolerance, normal) or abnormal (not tolerance, not OK). However, the concept of “norm” in this case is subjective and vague (fuzzy) concept. Will use in place of “norms” when it comes to defining abnormality other clear concepts, such as minimum, average (arithmetic mean, weighted, quadratic, exponential, etc.), average (expectation and variance), background values of the measurement parameters of the object or process. For example, the average value of the i-th measurement parameter can be represented as

whererespectively the maximum and minimum values of the i-th measurement of the parameter.

Define the expression (2) as the unit of measure of abnormal values measurement parameter of an object or process. Then this unit of measure can be used as a benchmark for evaluation of characteristics of the anomalous values of the measurement parameters and, respectively, to assess the characteristics of abnormal conditions (anomalies) of the object or the parameter you can use its minimum, the average or background values.

The set of possible anomalous values measurement parameter can be represented by some set of classes of anomalies). Imagine the possible classes of anomalous values of the i-th measurement parameter as

whereclass values measurement parameter corresponding to some norm, the value of which can be accurately determined by choosing an expert analyst of the specific measures measurement values measurement parameter, for example, in the form of minimum, average, average, or background values,- a slight excess,- a two-fold excess or twice anomalya threefold excess or triple anomaly, etc.

For some types of objects, the characteristics of the anomalies can be represented by the anomalous values of the i-th measurement parameter as

where- a small positive excess or positive one-time anomaly,positive two-fold excess of positive or twice anomaly- negative two-fold excess or double negative anomaly, etc.

Depending on the purpose of analysis and characteristics of the object (the source of perturbations or abnormalities), a specific value of the measurement parameter may vary depending on those or other spatial variables R object. For example, as P can be spatial coordinates (l is the length, h - width, and g is the depth or height, where lL, hH, gG). Many of the observed values of the measurement parameter (the line in the array of experimental data), estimated in accordance with expressions (3)-(4) depending on the spatial coordinates, determines respectively the state of the object or process from the point of view of the impact of anomalies on the parameter in question.

The set of values of the measurement parameters, evaluated in accordance with expressions (3) or (4) depending on varying the magnitude R of the object, determines, respectively, the generalized (integral) condition from the point of view of the influence of animal the UNC (integral) analysis to identify sources of anomalies on a large number of anomalous values of the measurement parameters causes certain difficulties. This is due to several causes, among which the main is the multidimensionality of the object of study or the so-called “curse of dimensionality”.

We propose the following approach. We introduce a generalized (integral) characteristic anomalous values of the given set of measurement parameters

where I is the total number of measurement parameters (signs, symptoms) of the studied object, which is estimated anomaly (anomalyfor some variable P, I*(P,- the number of measurement parameters whose value depending on the particular value of R is assigned to one of the classesanomalies in accordance with the expression (3) or (4), And*(Kkthe relative number of parameters related to a particular value of P to the class of anomalies To ak.

Next, using Tsvetkova form view, you can convert the original data matrix (1) in Tsvetkova matrix-a histogram of the status of the object. Thus, by encoding specific color code of the visible spectrum of each of the selected classes (3)-(4) anomalous values measurement parameter and Tsvetkova matrix-histogram

where z(R) - Tsvetkova information of the visible spectrum corresponding to the identified k-th class of anomalieson the i-th measurement parameter, R is the spatial coordinate of the measurement values, which depend on the location of the source of disturbance (anomalies),sign Cartesian product of sets.

The physical content of the measuring parameter is determined by the characteristics of the studied object or process, and may be different. Therefore, to consider the anomalies of the form (3)-(4) it is possible for objects of any physical nature, such as gravity and magnetic (electromagnetic) anomalies, anomalies in the content of chemical elements in a sample or in the analysis in medical diagnosis, etc., However, despite the differences in the objectives of the analysis of abnormal values of the measurement parameters, the proposed method is invariant with respect to the object of analysis.

The essence of the proposed method is illustrated on the example of detection of various anomalies in the analysis of geological and geophysical data. The main task of search of Geology in the search fields or Pinpoint the source of the anomalies (anomalous values of the measurement parameters of multidimensional object or process. Consider the geochemical anomalies, which understand the plot of the geological environment, which differs significantly high or low concentrations of any chemical elements and their compounds in comparison with the background values. Such significantly different concentrations of chemical elements in nature are usually relatively accumulations of minerals (ore, oil or gas deposits, and others).

When geochemical studies source of anomalies is significant variation in the content of a given chemical element (measuring parameter) from the norm (given measure). In this case, as the variable R can be as spatial coordinates (drilling depth), and their derivatives, such as the number of samples.

Let the value of the anomalous values analyzed the i-th measurement of the parameter, in this case, the content of the i-th chemical element, characterized by the expression (2), where- the content of the i-th chemical element in the normalclass of anomalies, characterized by a slight excess,class of anomalies, /img_data/83/830166.gif">- a four-fold excess, and so on, Respectively, the magnitude of the abnormal value (i+1)-th measurement parameter (content (i+1)-th chemical element) is also characterized by the expression (2), where- the content of the (i+1)-th chemical element in the normalclass of anomalies, characterized by a slight excess,class of anomalies characterized by a twofold excess of norms, etc.

Integral evaluation of the entire set of experimental data can be obtained by generalizing the expression (2) over a large number of measurement parameters (obtained measurements of the content of chemical elements). For example, summarizing the contents of all the analyzed chemical elements in the set P of spatial coordinates (samples geological layer P=h, on the well depth, R=I and other). Obviously, the specific value of the measure of abnormal values for each measurement parameter (the contents of a particular chemical element) will be significantly different, which is taken into account in the calculations. However, for this method of representation is not essential, since the analysis is conducted in relative terms, and their causal dependencies of the distribution.

Applying the proposed method obtained Tsvetkova matrix-histogram States geological well as of the wide variety of measurement parameters - the content of some set of chemical elements

where z(I) - Tsvetkova information corresponding to a particular (estimated)depending on the spatial coordinates of the wells (location of the depth of disturbance or anomaly).

Visual analysis view (see drawing), revealing the essence of the proposed method allows to:

to determine the location of the source of the anomalies (assumed deposits studied chemical element and ontologically related other minerals) extreme values and mean Cvetkovi histogram of anomalies of different levels (multiplicity). So, for the intervals (I3-I4) and (I10-I11) on the x-axis with the highest probability timed anomalousness objects;

to estimate the distribution of Cvetkovi histogram classes anomalous values of the content of the whole population under consideration hee is I'm on a visual level the nature of the distribution of the different histograms twice, three anomalies;

a visual assessment of the correlation (matching and mutual distribution histograms classes anomalous values of the content of the chemical element depending on the spatial coordinates locate the source of the anomalies.

It should be noted that the proposed form of presentation of information in the form of Cvetkovi matrix of histograms (5)-(6) is a very succinct and very clear, as it allows to describe and visualize large amounts of experimental data. The size or cardinality of the measurement parameters, summarize using the relation (4) may vary and is not limited within the proposed form tsvetkovogo view as conversion operations and assessments are not absolute and relative values.

Obviously, such information is necessary for the visual analysis of the studied object or process, which is performed by an experienced expert analyst.

Thus, the proposed method for the visual representation and analysis of abnormal values of the measurement parameters of the multidimensional object or process can be considered as a new allocation method (recognition, the identifier is then anomalous values of the measurement parameters of any multidimensional object or process.

A practical example of implementation of the proposed method shows its quite simple the feasibility of using the computer, thus, the requirement of industrial feasibility of the method.

Thus, the proposed method can be used in both small and large sets of experimental data that confirms the universality of the proposed representations, and the feasibility of the proposed method on a computer.

The set of essential features that lead to the desired result, in the patent and scientific literature is not detected, indicating that the “inventive step” of the proposed technical solutions. The novelty of the proposed method in comparison with the prototype and known methods of presentation and analysis of anomalies, is that developed logical sequence of steps for the visual representation and analysis of abnormal values of the measurement parameters of the multidimensional object, which leads to the achievement of the objectives of the invention.

The object of study, the observed measurement parameters can be very different in their physical content. Cvetkovi description of the object can also be different is the descriptions of the classes of anomalies, the characteristics of the distribution of anomalies etc). However, underlying the method is a logical set of actions on visualization and analysis of abnormal values of the measurement parameters is invariant to the nature of the object or process, which is an advantage of the proposed method. Thus, the resulting invariance property descriptions and representations Cvetkovi matrix of histograms allows you to maximize generalization that allows widespread implementation of the proposed method in various practical applications.

For conducting on-line (real measurements) analysis of anomalous values of the measurement parameters of multidimensional objects or processes a very effective use of this method is the mode of observation or monitoring (on-line viewing of data by computer). Operational analysis can be performed on a particular object, and when viewing the analyst data (samples) from different databases, data warehouses, archives. For example, the review and analysis of the on-screen multicolor video display different data from the database geo is subramania
