In this paper, a Neural Network Deployment (NND) algorithm is presented to realize and synthesize Multi-Valued Logic (MVL) functions. The algorithm is combined with back-propagation learning capability and MVL operators. The operators are used to synthesize the functions. Consequently the synthesized expressions are applied by the MVL neural operators. The advantages of NND-MVL algorithm are demonstrated by accuracy measurement of MVL neural operator realization. Furthermore, evaluation of NND-MVL algorithm is analyzed by its application, propagation delay and accuracy achieved for training with 4 hidden neurons. In a brief, an effort of training MVL neural operators and utilizing them for logic synthesis is observed.

A novel background calibration technique for the residue amplifier gain of a pipeline time-interleaved analog to digital converter (TI-ADC) is proposed in this paper. The technique is based on the backpropagation algorithm, which is widely used in neural network training, and can be applied to any pipeline topology, regardless of the number of stages. backpropagation-based calibration is applicable to digital communication receivers, and the particular application discussed in this paper is coherent optical transceivers. The technique is able to operate in conjunction with other backpropagation-based TI-ADC mismatch calibration algorithms without introducing additional complexities. The main advantages of the technique proposed here are its robustness, its speed of convergence and the fact that it always works in background mode, which makes it suitable to track any process, voltage and temperature variations. Simulations are reported to demonstrate the effectiveness of the proposal for two different pipeline ADC topologies.

Telecommunication fraud prediction in this paper is an interpolation problem that uses the daily telecommunication network services information to analyze and predict the alarm information generated from a detection engine by minimizing false cases. This paper proposed the use of backpropagation neural network (BPNN) to perform telecommunication interpolation based on local telecommunication network services. The backpropagation algorithm is adjusted accordingly to control the speed of obtaining solution. The validation of this method is carried out following a series of experiments to establish the suitable BPNN parameters value for this interpolation problem. 20,000 cases were used and divided suitably into training and testing samples in analyzing the performance of the BPNN network. It is observed that the performance of BPNN in predicting fraud was merely 100% if the threshold value was set to 0.64 and above the predicted value. Consequently, the network model created could be used to analyze fraud risk classification and subsequently, provide contribution to the domain of fraud detection system.

This work describes and compares the backpropagation algorithm with the extended Kalman filter (EKF), a second-order training method which can be applied to the problem of learning neural network parameters and is known to converge in only a few iterations. The algorithms are compared with respect to their effectiveness and speed of convergence using simulated data for both, a regression and a classification task.

FUZZY SETS AND SYSTEMS 1992年第3期50卷 257-265页

作者： ISHIBUCHI, H TANAKA, H Department of Industrial Engineering University of Osaka Prefecture Sakai Osaka Japan

In this paper, we propose simple but powerful methods for fuzzy regression analysis using neural networks. Since neural networks have high capability as an approximator of nonlinear mappings, the proposed methods can be applied to more complex systems than the existing LP based methods. First we propose learning algorithms of neural networks for determining a nonlinear interval model from the given input-output patterns. A nonlinear interval model whose outputs approximately include all the given patterns can be determined by two neural networks. Next we show two methods for deriving nonlinear fuzzy models from the interval model determined by the proposed algorithms. Nonlinear fuzzy models whose h-level sets approximately include all the given patterns can be derived. Last we show an application of the proposed methods to a real problem.

Proposal of a declarative and parallelizable artificial neural network using the notification-oriented paradigm

Since the 1960s, artificial neural networks (ANNs) have been implemented and applied in various areas of knowledge. Most of these implementations had their development guided by imperative programming (IP), usually resulting in highly coupled programs. Thus, even though intrinsically parallel in theory, ANNs do not easily take an effective distribution on multiple processors when developed under IP. As an alternative, the notification-oriented paradigm (NOP) emerges as a new programming technique. NOP facilitates the development of decoupled and distributed systems, using abstraction of knowledge through logical-causal rules, as well as the generation of an optimized code. Both features are possible by means of a notification-oriented inference process, which avoids structural and temporal redundancies in the logic-causal evaluations. These advantages are relevant to systems that have parts decoupled in order to run in parallel, such as ANN. In this sense, this work presents the development of a multilayer perceptron ANN using backpropagation training algorithm based on the concepts of a NOP implementation. Such implementation allows, transparently from high-level programming, parallel code generation that runs on multicore platforms. Furthermore, the solution based on NOP, when compared against the equivalent on IP, presents a high level of decoupling and explicit use of logic-causal elements, which are, respectively, useful to distribution, understanding and improvement of the application.

A cumulative-risk assessment method based on an artificial neural network model for the water environment

ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH 2021年第34期28卷 46176-46185页

To analyze the cumulative risks to the water environment, the backpropagation artificial neural network (BP-ANN), a self-adapting algorithm, was proposed in this study. A new comprehensive indicator of cumulative risks was formed by combining the water risk assessment tool proposed by the World Wide Fund for Nature or World Wildlife Fund (WWF), Deutsche Investitions und Entwicklungsgesellschaft mbH (DEG), and the cumulative environmental risk assessment system proposed by the US Environmental Protection Agency (USEPA). Eleven training algorithms were selected and optimized based on the mean square error (MSE) of prediction results. Data concerning evaluating indicators and cumulative risk indexes of the Liao River collected from 2005 to 2017 in the cities of Tieling, Shenyang, and Panjin, China, were used as input and output data to train, validate, and test the BP-ANN. Levenberg Marquardt backpropagation was the most accurate algorithm, with an MSE of 3.33 x 10(-6). After optimization, there were six hidden layers in the model. The correlation coefficient of the BP-ANN with LM exceeded 80%. These findings suggest that the BP-ANN model is applicable to prediction of cumulative risks to the water environment. The model was sensitive to the number of wastewater treatment facilities and the wastewater treatment rate along the river. Based on the sensitivity analysis, the contributing factors can be controlled to reduce the cumulative risk.
