Details on Neurali nets for the analyses

Investigators of LABORAF - Diagnostic and Saint Search Raffaele joint-stock corporation has developed and used for before it turns a software neuro-fuzzy, an example of artificial intelligence applied to the laboratory analyses

For before the time investigators of the Saint Raffaele they have put to point a software for the interpretation of the elettroforesi capillary, a useful examination to the study of proteins and a lot important in the diagnosis of some pathologies of the immune system. The new software, called FuzzyLab, concurs to obtain turns out qualitatively better to you and than to pull down than of 80% the times of refertazione of the examination, to all advantage not only of the doctor but also of the patient.

FuzzyLab is a type software neuro-fuzzy, it is that is based on one combination of neurali nets and logic fuzzy. The neurali nets are one risen of artificial brain in a position to continuously improving the own ability to learning. Logic fuzzy renders the processes of calculation of "the more flexible" computer. Draft of one logical applied already from some year to many products of wide consumption that as an example allows the washing machines of last generation to dose water and detersivo based on the level of dirt of the bucato one. Fuzzylab carries out quickly and in way of all the automated one and standardized the job of interpretation of the elettroforesi capillary until today executed manually and subject to the interpretation of the doctor. "In a laboratory of great dimensions" - Stefania Of Red, the responsible one of theLaboraf-Diagnostica Protein laboratory explains and Saint Ricerca Raffaele- "350 elettroforesi are carried out every day in average, whose reading demands to an expert doctor at least two hours of job. In order to carry out the same task the software employs alone 20 minuteren.

In this way the doctor can distinguish fastly between normal "and pathological outcomes" and more dedicate therefore the saved time to the analysis of the examinations criti to us and more difficult to interpret ". The elettroforesi capillary analyze proteins of the serum and, beyond supplying indications of character much general on inflammatory states and possible hepatic suffering, servants in order to reveal the presence of one monoclonale member - with of antibodies all equal ones between they - produced in various cases of alterations of the immune system. The monoclonali members are correlated as an example to malignant linfoproliferative pathologies like the mieloma multiple, the chronic linfatica leukaemia and the lymphomas; the elettroforesi can moreover be important for sottoporsi to one TAC. In this case, in fact, the presence of one monoclonale member can interfere with some means of contrast uses you for the examination, triggering one dangerous anaphylactic reaction.

In order to learn to read the analyses, FuzzyLab has been subordinate to a true one and just training articulated in three is made. In the phase "student" begins them the software has been instructd to recognize the shape of the normal elettroforetiche curves with a mathematical algorithm, on the base of the data supplied from the medical "trainer". In the second phase they have been put to point and inserted in the computer the mathematical formulas for the identification of the pathological curves. In the third phase, of validazione of the system, the manual interpretation and that one of FuzzyLab have been put to comparison in order to estimate of the error margin, inferior result to 2%.

The system is extremely flexible and potentially in a position to increasing just the modernization with the experience, as the attached doctors use the program and insert new data, therefore com' it is in logic of the neurali nets. "the advantages of this approach are important and multiple it is for the doctor it is for the patient", it says Michelangelo Murone, assistant manager of Laboraf. "first and the most obvious one is the reduction of the times of refertazione that allows to the analyst of having more time disposition in order to examine the pathological tracings. Little important is not the improvement of the interpretativa quality, than it is translate in an in the first place surer refertazione, because the pathological curves come analyzed in double quantity, before from the software and then from the doctor, but also more objective and standardized, because Fuzzylab reduces the probability of errors and eliminates the risk of interpretative differences tied to the human factor ".

Neurali logic fuzzy, nets and software neuro-fuzzy: deepening

The FuzzyLab program, developed from Lorenzo Schiavina, university professor of mathematics to the Catholic University of Brescia, is an expert system of type neuro-fuzzy, that is an application that belongs to the area of the artificial intelligence, based on one fusion of neurali nets and logic fuzzy. The neurali nets are instruments of calculation that reproduce the structure of base and the processes of learning of the brain, in such way from being able to be trained with particular algorithms to supply the same answers that an expert human to demanded detailed lists would give.

Logic fuzzy is instead an extension of traditional binary logic (of "yes or not", of the "true or false one") on which they are it bases the normal programs to you for computer and has been introduced just in order to exceed this excessive schematismo. "Fuzzy" in English means in fact vague, indefinite, vanished, and logic fuzzy allows the computers not to classify the data that must only elaborate like "all black white man" or "all", but also to consider the innumerevoli means ways comprised between the two ends, also maintaining mathematical the rigor typical of the calculating. Therefore it is particularly adapted to represent the acquaintance of an expert human of the truth, that variegata, multishapes and sfaccettata.

Laboraf - the laboratory of analysis of the Saint Raffaele

Laboraf, Diagnostic and Saint Search Raffaele joint-stock corporation, are born in the june of the 2002 from a experience of beyond 30 years in the field of the diagnostic one and the search of laboratory to the inside of the University Scientific Institute Saint Raffaele. From 1970 until today the analysis fields they are it diversifies to you and it specializes to you until comprising beyond 25 specialistici laboratories, all equip you of instrumentation to the vanguard and in a position to taking advantage themselves of the more modern techniques of diagnostic surveying.

It executes more than 6.000.000 than various analyses of laboratory to the year, 700 types of test, 50 methodical new every year. It counts beyond 2.000 customers to the day and 300 customers in service. From the 1998 all the laboratories of Laboraf analysis are certify UNI to you EN ISO 9002 and from 2002 UNI EN ISO 9001:2000.
