Inductive view on science was classically Inductive view on science was classically described by J.S.Mill in his "described by J.S.Mill in his "System of logicSystem of logic" " (1843); it presupposes that scientific researches (1843); it presupposes that scientific researches must begin from free and unprejudiced observation must begin from free and unprejudiced observation of facts, then have to be continued by the inductive of facts, then have to be continued by the inductive formulation of universal laws, which describe these formulation of universal laws, which describe these facts, and, finally, to come to the more general facts, and, finally, to come to the more general conclusions (conclusions (it is agreed to call them "theories"). ). But, if to imagine the science as the sequence of But, if to imagine the science as the sequence of infinite attempts of existing hypotheses' refutation infinite attempts of existing hypotheses' refutation and to replace them by another, and to replace them by another, non-falsifiable statements , it should be naturally to ask, where statements , it should be naturally to ask, where these hypotheses appear from.these hypotheses appear from.

1. Levels of Inductive 1. Levels of Inductive ConclusionsConclusions

It is proposed to consider different levels of hypotheses. It is proposed to consider different levels of hypotheses. Let distinguish, at least, two levels: Let distinguish, at least, two levels:

1)1) " "what does depend from whatwhat does depend from what" (Popperian " (Popperian conception, in the our opinion) and conception, in the our opinion) and 2)2) " " how it dependshow it depends" (position of J.S.Mill, we " (position of J.S.Mill, we suppose).suppose).

• Evidently, intuitive surmises, an experience, the talent of Evidently, intuitive surmises, an experience, the talent of researcher (i.e. the matters lying in sphere of psychology), researcher (i.e. the matters lying in sphere of psychology), and, sometimes, also metaphorical or associative and, sometimes, also metaphorical or associative conclusions, correspond to the conclusions, correspond to the first levelfirst level. On this level we . On this level we define a define a composition of properties which are means by those which are means by those the object (examined or designed) displayed itself.the object (examined or designed) displayed itself.• Inductive methods of Bacon-Mill and, certainly, methods of Inductive methods of Bacon-Mill and, certainly, methods of probability theory as well as mathematical statistics already probability theory as well as mathematical statistics already correspond to the correspond to the second levelsecond level. Here we define the structures . Here we define the structures of dependencies parametrically: of dependencies parametrically: which is the pattern of certain dependencies.

But refutaion of hypotheses generated on the first level But refutaion of hypotheses generated on the first level are also possible. Furthermore, on the first level it would are also possible. Furthermore, on the first level it would be reasonable to include "be reasonable to include "doubtful" (" (extra, additional) ) valiables (properties, parameters) specially.valiables (properties, parameters) specially. The first level would be defined as The first level would be defined as quantitative and the and the second one - as second one - as qualitative. That is why many of . That is why many of specialists-logicians consider the first level case as specialists-logicians consider the first level case as inductive reasonings (as they generate fundamentally new inductive reasonings (as they generate fundamentally new knowledge «in principle»); but they refuse to say in the knowledge «in principle»); but they refuse to say in the same way concerning the inference on the second levels. same way concerning the inference on the second levels. Logicians also propose to distinguish both Logicians also propose to distinguish both plausible and and probabilistic inference (which have strongly pronounced inference (which have strongly pronounced numeral measure of likelihood degreenumeral measure of likelihood degree).). Selected levels correspond to G. Klir's epistemological Selected levels correspond to G. Klir's epistemological levels of systems hierarchy.levels of systems hierarchy.

Here we are interested, in a greater extent, in Here we are interested, in a greater extent, in CERTAIN and and PLAUSIBLE kinds of logical inference. kinds of logical inference. Certain inference is produced by Certain inference is produced by deductive reasoning, , whereas the plausible one is generated by all whereas the plausible one is generated by all others kinds of reasoning. . It is not accident that any mathematical proof represents It is not accident that any mathematical proof represents the deductive "chain". the deductive "chain". It also concerns the criminal evidence (see, for instance, a It also concerns the criminal evidence (see, for instance, a final of nearly every detective novel).final of nearly every detective novel). All other versions of reasoning are only plausibility. All other versions of reasoning are only plausibility.

Certainly, the hypothesis is always only Certainly, the hypothesis is always only plausible. But there are some exceptions.plausible. But there are some exceptions. For For example, the full (in particular, mathematical) induction.example, the full (in particular, mathematical) induction.

Earlier it was widely accepted to consider that only

inductive conclusions allow to generate a hypothesis. Then

C. S. Peirce proved "inconsistency" of the induction in many

cases and introduced [6] the notion of abductive conclusion.

Moreover, he believed that just this class of reasoning is

basic in hypotheses formation .

We shall emphasize the main thing, from our point of

view, the difference of abduction from induction.

By means of abduction the hypothesis is formed as the

cause of some (observable) event. There would exist more

than one such a cause. More often they (causes) are

connected by the operator OR.

With the help of induction the generalization of several

events is made. These events are bounded by operator AND.

From our point of view, From our point of view, TRADUCTIVE CONCLUSIONSTRADUCTIVE CONCLUSIONS are are not less important during process of generation of not less important during process of generation of hypotheses. We shall remind, that hypotheses. We shall remind, that traduction ( (from Latin traductio - moving) is the inference, where the premises and ) is the inference, where the premises and the conclusions are judgements of identical commonness, the conclusions are judgements of identical commonness, that is, the inference goes from knowledge of the certain that is, the inference goes from knowledge of the certain extent of commonness to new knowledge, but of the same extent of commonness to new knowledge, but of the same extent of commonness. extent of commonness. The The ANALOGY, which we frequently use both during , which we frequently use both during synthesis of a hypothesis, and in its justification or synthesis of a hypothesis, and in its justification or refutation, is traductive conclusion (refutation, is traductive conclusion (remind the dialogues of remind the dialogues of SoсratesSoсrates). Both ). Both METAPHOR and and ASSOCIATION are versions are versions of the conclusion by analogy. of the conclusion by analogy. And the power of these versions of conclusions in And the power of these versions of conclusions in formation of hypotheses (especially, original) is difficult to formation of hypotheses (especially, original) is difficult to overestimate.overestimate.

Relation of similarity lies in the basis of any model

Hence, the Hence, the modeling is the inference by analogymodeling is the inference by analogy.

It is not accidently that the theory of models (and

theory of categories) in mathematics, generally

deals with morphisms (conformity). In general, it is

possible to construct an opposition scale

Certainly, in practice any models can be the basis of

We shall notice that the data matrix is also the model. Abduction is also a sort of traduction

It looks quite obviously that the person during generation

of hypotheses uses continuously all versions of available

reasoning, dynamically passing from one to another.

Thus we not always clearly realize what logical procedures

do help us to come to one or another hypothesis and how we

prove it.

3. One more view on induction. One more view on induction In philosophy and logic it is considered that the induction In philosophy and logic it is considered that the induction is higher form of the thinking as compared with deduction; is higher form of the thinking as compared with deduction; and it is directly related to creative, innovative style of and it is directly related to creative, innovative style of thinking resulted in new knowledge. thinking resulted in new knowledge. But in modern logic there is no unequivocal definition of induction.. Generally, the approaches to understanding the inductive Generally, the approaches to understanding the inductive inference are based on inference are based on contents analysis of situation. In In accordance to this view the methods of inductive inference accordance to this view the methods of inductive inference are grounded on some common philosophic prerequisites are grounded on some common philosophic prerequisites like as “like as “induction is the searching of the phenomenon's cause”" or "" or "deduction is the transition from general to particular, and induction is contrary to deduction". ". Despite their attraction, these prerequisites give us a very Despite their attraction, these prerequisites give us a very little benefit from standpoint of mathematical formalism of little benefit from standpoint of mathematical formalism of inductive inference, moreover, they are obviously deficient inductive inference, moreover, they are obviously deficient to map some features of innovative thinking by means of to map some features of innovative thinking by means of formal logic.formal logic.

Kulik BA.Kulik BA. proposes another way of inductive inference: proposes another way of inductive inference: formation of plausible hypotheses is accomplished by multivariate reconstruction of missing links in some deductive structure. That kind of deductive structure in view of its features That kind of deductive structure in view of its features “allows” to employ just a limited quantity of hypotheses of “allows” to employ just a limited quantity of hypotheses of infinite set of statements. It is clear that in this case at once infinite set of statements. It is clear that in this case at once several acceptable hypotheses can appear. Then the final several acceptable hypotheses can appear. Then the final choice of proper hypothesis can be made not on basis of choice of proper hypothesis can be made not on basis of the probability computations, but on basis of their the probability computations, but on basis of their contents contents analysisanalysis, when the knowledge that contained not apparently , when the knowledge that contained not apparently (implicitly) in initial deductive structure is used. (implicitly) in initial deductive structure is used. From our point of view, such an understanding of induction lies closer to Sharlock Holmes's reasoning manner and, per se, it appears as abduction.

4. Properties of hypotheses4. Properties of hypotheses It is impossible to take actions for problem solving without some hypothesis. Even in case of evident practical tasks their decision is made on the basis of the previous experience and skills acquisited, which forms a preliminary imagination or a pattern (an idea) of possible ways of solving. That is the hypothesis is such an imagination or an idea. It is necessary to note, that the hypothesis always contain bigger contents and greater explanatory power than data, which support hypothesis. As the hypothesis does not concern to individual judgments of experience and always exceeds them in contents, it cannot be proved only on the assumption of data. The empirical data just are able to disprove a hypothesis, but not to verify it. The hypothesis is prejudiced even though it contradict at least one fact. But each new hypothesis, as a rule, does not reject the contents of former hypotheses fully, but uses all rational considerations. The new hypothesis acts basically as perfected previous one.

In order to separate the In order to separate the most credible hypotheses from the from the initial conjectures some limitations are put upon their initial conjectures some limitations are put upon their formulations: formulations:

1.1. Тhe hypothesis has to be both Тhe hypothesis has to be both syntactically right and semantically understandable statement within certain text;;

2.2. The hypothesis has to be proved, to some extent, on The hypothesis has to be proved, to some extent, on previos knowledge or, in a case of its complete or, in a case of its complete originality, originality, not to contradict scientific knowledge;;

3.3. The hypothesis has to be not only verifiable in The hypothesis has to be not only verifiable in principle principle when the knowledge changes, but also must be checkable by available methods, i.e. it should , i.e. it should comply with development of scientific tools.comply with development of scientific tools.

The restriction mentioned above are both necessary and The restriction mentioned above are both necessary and sufficient conditions to qualify a hypothesis as the scientific sufficient conditions to qualify a hypothesis as the scientific utterance regardless of its truth or falsity in the future.utterance regardless of its truth or falsity in the future.

Scientific (and any other) idea does not start from

scratch. In order to submit a hypothesis to

consideration, somebody have to relate it to knowledge

existed before; just in that case this hypothesis could be

a subject of investigation and further testing.

Indeed, such a substantiation is not final, often the

different grounds are found for identical hypotheses.

But, this fact is only evidence that validity of the

hypothesis is the necessary requirement of its

acceptability — absence of due validity discredits the

hypothesis to such a degree, that it cannot then remain

the point of further discussion.

Thus, during the generation of hypotheses it is necessary to work not only with data, but to use knowledge bases where the experience of different experts from various knowledge domains accumulated, structured and systematized. These knowledge bases have to contain models, which are collected and systematized from previous case studies (both adequate to a problem and "not quite" adequate; see also above, about the third and fourth Klir's levels). Besides, for generation of hypotheses not only inductive reasonings (or methods of mathematical statistics), but also abduction and traduction should be used.

5. Some words on Data mining and Data Warehouses

Humans commonly try to understand their environment by simplification (reduction). In process of learning the human observes surrounding environment and defines interrelations between objects and events in this environment. Then person makes the grouping of similar objects into classes and builds rules, which predict the behaviour of such objects within certain class. Thus, such a model is always related to

• hypotheses generation, on the one hand• classification and recognition the other hand.

By similar way it is possible to learn computer. Studying and simulation of the process of learning is one of the research fields in Artificial Intelligence (AI) has the name machine learning.

As a rule, machine learning systems do not operate with isolated data, but they deal with the complete set of observations at once. Such a set named the learning set or learning sample. Data mining (analysis) from databases is one of having practical value methods during the searching the inductive dependencies from raw data. Although knowledge extraction from databases is a sort of machine learning, there exist some aspects of its considerable distinction from other machine learning applications.

1.1. The first and main distinction is that databases are designed without regard of needs of specialists in sphere of generalization. Knowledge extraction systems have to operate with fully prepared databases have been designed for the needs of other applications. There should not be program modules to ease the learning process in such systems. In decision support systems this problem led to In decision support systems this problem led to development ofdevelopment of Data Warehouse (DWH) ideology; they are they are specially oriented on information support of certain specially oriented on information support of certain processes.processes.

2.2. The second important distinction is that The second important distinction is that real databases often contain errors. While thoroughly matched data are . While thoroughly matched data are used for machine learning, algorithms of data extraction used for machine learning, algorithms of data extraction from databases have to deal with from databases have to deal with noisy and sometimes conflicting data.

Such a methodology has to support synthesis Such a methodology has to support synthesis and analysis of hypotheses by means of continuous and analysis of hypotheses by means of continuous interaction of corresponded coherent processes of interaction of corresponded coherent processes of reasoning.reasoning.

Conclusion This issue concern the some actual problems of hypotheses generation. Several important aspect of the generation processes are considered. We suppose that deficient attention to the formation and justification hypotheses processes is one of important reason of low efficiency of many computer technologies. The clear understanding of different kinds of the logical inference as well as better vision of fundamental relations between logical, cognitive matters and theoretical grounds of systemological disciplines, we hope, could help to move forward . It seemed to be necessary the broad scientific (interdisciplinary) discussion on problems and matters

stated in this paper.
