Abstract: PURPOSE:To improve the recognition accuracy and the maximum likelihood of a partition point by using a pattern associative type neural network and a recurrent neural network, and executing the recognition of a partition by taking notice of an electrocardiogram waveform of that time and a timewise structure of the partition. CONSTITUTION:A leaning/recognition control part 16 fetches a value St of an electrocardiogram waveform of the present time point (t) of the electrocardiogram and its partition Kt from a standard waveform/partition pattern memory part 11, and uses them for the learning of internal parameters of a pattern associative type neural network 12 and a recurrent neural network 13. The network 12 sets a signal S't obtained by superposing the value St of the electrocardiogram waveform of the time point (t) and the output Nt of a noise generator 14, and a partition Kt-1 of the time point (t)-1 as input signals, sets the partition Kt of the time point (t) as a teacher signal, and updates the internal parameter of the network 12. The network 13 sets the partition Kt-1 of the time point (t)-1 as the input signal and sets the partition Kt of the time point (t) as the teacher signal, and updated the internal parameter of the network 13.

Abstract: PROBLEM TO BE SOLVED: To provide a biological information retrieval system and method for solving a problem in retrieving a biological database that it is impossible to retrieve a gene or protein with anything other than its name.
SOLUTION: A user input accepting part 11 which has received an inquiry from a user to a biological information database generates a user query 111, and a query generating part 12 generates a biological information database query 121, and a biological information database retrieval part 13 actually retrieves a biological information database 999, and outputs a biological information database retrieval result 133. A retrieval result analysis part 14 analyzes the retrieval result, and outputs an analysis result 142, and an output control part 15 receives the analysis result, and successively outputs it, and generates a re-retrieval query 151 for non-retrieval, and transmits it to the query generating part 12. An output information designating and holding part 16 preliminarily holds conditions associated with the extraction and output of the retrieval result.

Abstract: PROBLEM TO BE SOLVED: To provide a method and a system that can reduce the number of experiments in identification with a small amount of a sample and an experiment for trial-and-error, adds a mass spectrum that may appear, a peak or the like buried in noise, or the like for achieving a high accuracy in protein identification and high throughput, and can determine sequencing using mass spectrometry even in new protein that is not registered in a protein sequencing database. SOLUTION: In the mass spectrometry due to a tandem type mass spectrometry apparatus, bond dissociation energy is calculated by using a molecular simulation method, the prediction information of the cleavage pattern of peptide and/or the peak position of the mass spectrum and/or the intensity ratio of a spectrum is added to obtained experiment information for use as the identification of protein.

Abstract: PURPOSE:To improve both accuracy and likelihood of character recognition for a character pattern which includes a noise, rotates or moves in parallel. CONSTITUTION:A standard character pattern category memory part 11 holds N-pairs of standard character patterns for learning and the category. A pattern associated type neural network 12 learns with a standard character pattern St as an input signal and with a category Kt as a teacher signal and recognizes the character pattern St and the category Kt. A learning and recognizing control part 13 controls the actions of the learning and recognition of the pattern associated type neural network 12. The pattern from the external part becomes the input of the pattern associated type neural network 12 through an input area part 14. A constraint force control part 15 controls the influence of the spacious constraint force of the input area part. A switching part 16 switches the input to the pattern associated type neuralnetwork 12 between phases of the learning and the recognition.

Abstract: PURPOSE:To improve accuracy and exactitude for recognizing a dividing point by executing the recognition of the dividing point while paying attention to the time structure of an electrocardiogram waveform. CONSTITUTION:A standard dividing point pattern memory part 11 is provided to hold a standard part pattern and the dividing point of the waveform, and a noise generator 12 is provided to superimpose noise to the standard pattern and to increase the kind of learning patterns. Then, a recurrent neural network part 13 is provided to segment the dividing point from the learning pattern, to which the noise signal is superimposed, and a learn control part 14 is provided to control the learn of the recurrent neural network part 13. The recognition of the dividing point is executed while paying attention to the time structure of the electrocardiogram waveform. Thus, both the accuracy and the exactitude is improved for recognizing the dividing point and by executing the recurrent neural network learning based on the waveform for which the noise is superimposed to the standard pattern, only the specified learning pattern can be prevented from being over learnt.
