  • feed forward neural networks training a comparison between genetic algorithm and Back Propagation learning algorithm
    International Journal of Innovative Computing Information and Control, 2011
    Co-Authors: Tzuan Chiang, Z H Che
    Abstract:

    This study discusses the advantages and characteristics of the genetic algo- rithm and Back-Propagation neural network to train a feed-forward neural network to cope with weighting adjustment problems. We compare the performances of a Back-Propagation neural network and genetic algorithm in the training outcomes of three examples by re- ferring to the measurement indicators and experiment data. The results show that the Back-Propagation neural network is superior to the genetic algorithm. Also, the Back- Propagation neural network has faster training speed than the genetic algorithm. How- ever, the Back-Propagation neural network has the shortcoming of overtraining, while the genetic algorithm does not. The experiment result proves that the Back-Propagation neu- ral network yields better outcomes than the genetic algorithm.

  • pso based Back Propagation artificial neural network for product and mold cost estimation of plastic injection molding
    Computers & Industrial Engineering, 2010
    Co-Authors: Z H Che
    Abstract:

    To simplify complicated traditional cost estimation flow, this study emphasizes the cost estimation approach for plastic injection products and molds. It is expected designers and R&D specialists can consider the competitiveness of product cost in the early stage of product design to reduce product development time and cost resulting from repetitive modification. Therefore, the proposed cost estimation approach combines factor analysis (FA), particle swarm optimization (PSO) and artificial neural network with two Back-Propagation networks, called FAPSO-TBP. In addition, another artificial neural network estimation approach with a single Back-Propagation network, called FAPSO-SBP, is also established. To verify the proposed FAPSO-TBP approach, comparisons with the FAPSO-SBP and general Back-Propagation artificial neural network (GBP) are made. The computational results show the proposed FAPSO-TBP approach is very competitive for the product and mold cost estimation problems of plastic injection molding.

  • transmitter side digital Back Propagation with optical injection locked frequency referenced carriers
    Journal of Lightwave Technology, 2016
    Co-Authors: Eduardo Temprana, Evgeny Myslivets, B P P Kuo, Nikola Alic, Stojan Radic
    Abstract:

    A 100% reach extension is demonstrated in a coherent four-channel wavelength division multiplexed system by employing full-bandwidth frequency-referenced transmitter-side digital Back Propagation. Frequency referenced optical carriers are generated by injection locking distributed feedBack lasers to a reference optical frequency comb and the performance of digital Back Propagation is evaluated with and without the frequency reference. In addition, we investigate the effect of an implementation with reduced computational complexity by limiting the number of steps-per-span used in the Back Propagation computation. Lastly, we measure the penalties generated by an inaccurate fiber dispersion parameter in the Back Propagation model.

  • transmission reach doubling enabled by transmitter side digital Back Propagation and frequency referenced carriers
    European Conference on Optical Communication, 2015
    Co-Authors: Eduardo Temprana, Evgeny Myslivets, Lin Liu, Ana Pejkic, Vahid Ataie, B P P Kuo, Daniel J Esman, Andreas O J Wiberg, Nikola Alic, Stojan Radic
    Abstract:

    A 100% reach extension in a coherent Wavelength Division Multiplexing link is demonstrated relying on transmitter-side full-field Digital Back-Propagation and frequency referenced carriers. Transmission reach is extended from 1445 km to 2890 km for a 4-channel 16 GBaud 16-QAM system.
