  • A New Feature Extraction Technique For Classifiers Using Self-Organizing Map   Order a copy of this article
    by Prasenjit Dey, Tandra Pal 
    Abstract: Neural network classifiers suffer from the overfitting problem which reduces its generalization capability. Due to generalization, a trained classifier will always have good test accuracy. The objective of the proposed work is to improve the input space of the data set which in consequence will increase the generalization of the classifiers. For this purpose, we have proposed a new feature extraction technique based on self-organizing map (SOM). Initially, two-dimensional SOM network is trained to achieve topological ordering in the input data set. Then, a Gaussian function is used in each node of the output map of SOM network. It processes the input patterns sequentially and produces $m^2$ dimensional new representation corresponding to each input pattern, where $m^2$ is the number of nodes present in the output layer. Thereafter, classifiers like probabilistic neural network (PNN) or multilayer perceptron (MLP) is used over this new representation of the input patterns. The whole process creates a new classifier based on hybrid neural network model. We have used twelve standard classification data sets and compared proposed model with conventional PNN and MLP classifiers. Comparison of results shows the superiority of the proposed method. Wilcoxon signed rank test also shows that our SOM-based model used for transformation of feature representation improves the performance of the classifiers.
    Keywords: Feature extraction; Gaussian function; generalization; multilayer perceptron; probabilistic neural network; self-organizing map.

    Abstract: In this paper, the singularity preserving collocation methods are being developed for Fredholm integral equations of the second kind with the weakly singular kernel and for the corresponding eigenvalue problem. In this method, the interpolatory projected space is the direct sum of singular space and spline function space. The convergence rates for the approximated solution and iterated solution in weakly singular Fredholm integral equations of the second kind are being calculated. The error bounds for eigenvectors, eigenvalues, and iterated eigenvectors are also being obtained. We illustrate our results with numerical examples.

    Abstract: This paper presents a multiobjective bilevel programming (MOBLP) based interval goal programming (IVGP) method for modeling and solving to solve environmental-economic power generation and dispatch (EEPGD) problem using genetic algorithm (GA) in an inexact environment. In the proposed method, the objective functions to be optimized are represented as goals by introducing target intervals for the achievement of objective values in decision horizon. Then, using interval arithmetic rules, the defined planned -interval goals are converted into standard goals as in conventional goal programming (GP) to formulate minsum IVGP model of the problem. In the solution search process, a genetic algorithm (GA) computational scheme is employed in an interactive way to reach the solution of EEPGD problem The effective use of the approach is illustrated through a case example of the standard IEEE 30-Bus 6-Generator test system. The model solution is also compared with the solutions obtained by using other approaches studied previously.

  • Wheat Yield Forecasting Using Fuzzy Logic   Order a copy of this article
    by Tanya Sah 
    Abstract: Forecasting in general and crop yield forecasting, in particular, is considered a compound problem. Food and Agriculture Organizations report Global Agriculture towards 2050 accentuates the challenges which agriculture sector is going to face in near future. The report draws the attention towards the disparity between the demand and supply. It also highlights the issues that automation has introduced into the food and agriculture sector. Where there is a need to increase the production to feed the rapidly increasing population there is an equal necessity for coping up with the dwindling numbers of farm workers. As such, there is a need for a reliable forecasting algorithm capable of handling time series data. In this paper, we have proposed a fuzzy time series forecasting algorithm to forecast wheat yield. The reason to choose fuzzy over other forecasting methods is its capability of dealing with the vague, imprecise data and it outperforms many statistical conventional models in such conditions. The neural network has been used for training and defuzzification of the forecasted values.To attests the efficacy and the performance of the proposed method, it has been tested against the wheat production dataset.

  • A novel method for reduction of leakage current in MOSFET   Order a copy of this article
    by Debasis Mukherjee, B.V.Ramana Reddy 
    Abstract: In this paper, structural modification of conventional bulk MOSFET has been proposed for minimization of subthreshold leakage current. Key structural features of bulk MOSFET have been kept unaltered. Comparison of conventional and proposed structure has been presented for a 20 nm NMOS with 0.8 volt Vdd. The proposed structure is capable of reducing subthreshold leakage current even at very low drain voltage when the gate voltage is zero. Around 55 percent reduction of OFF current has been obtained when drain voltage is at Vdd and gate voltage is zero. The methodology proposed does not have any special requirement at the circuit level, and can be combined with all circuit level methodologies. The proposed structure is named as Defensive MOSFET as it looks like a defensive shield. Structural dimensions of 20 nm MOSFET generation have been taken from the 2011 edition of International Technology Roadmap for Semiconductors or ITRS. All simulation processes have been executed by Sentaurus G-2012.06 Technology Computer Aided Design or TCAD software.
    Keywords: 20 nm; leakage current reduction; NMOS.

    by Paulami De, Mrinmoy Majumder 
    Abstract: The Surface Water Treatment Plant (WTP) has an important role in the maintenance of water quality supplied to the consumers It was found from various studies that inflow water quality to a WTP plays an important role in the operation of the treatment plants. The nature and characteristics of the inflow water control the duration of treatment, dozing pattern etc. The temporal variation only one of the parameters like Turbidity of the inflow water can induce major adjustment in the plant operation and may also affect the efficiency of the WTP. Identification of temporal pattern can help the engineers to adapt the WTP operations and can save unnecessary wastage of plant resources. That is why in the present study a new model was proposed for prediction of the temporal patterns of various chemical parameters by adopting a new type of Artificial Neural Network model. The model was applied to predict the Turbidity concentration at the intake point of Bardowali WTP of Tripura which have a peri-urban settlement where Turbidity varies due to the urban runoff which disposes its suspended matters into the at the intake point of the WTP. According to performance metrics utilized the model was able to predict the temporal pattern of the model at 99% accuracy at a lag of 1 hour.
