چکیده

We show how eld-programable gate arrays can be used to eeciently implement neural nets. By implementing the training phase in software and the actual application in hardware, connicting demands can be met: training beneets from a fast edit-debug cycle, and once the design has stabilized, a hardware implementation results in higher performance. While neural nets have been implemented in hardware in the past, larger digital nets have not been possible due to the real-estate requirements of single neurons. We present a bit-serial encoding scheme and computation model, which allows space-eecient computation of the sum of weighted inputs, thereby facilitating the implementation of complex neural networks.

Use of a reliability coefficient in noise cancelling by neural net and weighted matching algorithms

The problems of e cacy estimation in noise cancelling by a neural net (LIN-Lateral Inhibition Net [5]) and the use of this information in weighting matching algorithms are focused. Since the e ect of noise on the speech signal is variable and the backpropagation training algorithm is essentially stochastic (most common patterns have more in uence in the weights re-estimation process), it is rea...

Learning to Control Fast-Weight Memories: An Alternative to Dynamic Recurrent Networks

Previous algorithms for supervised sequence learning are based on dynamic recurrent networks. This paper describes alternative gradient-based systems consisting of two feed-forward nets which learn to deal with temporal sequences by using fast weights: The rst net learns to produce context dependent weight changes for the second net whose weights may vary very quickly. The method o ers a potent...

A combined Wavelet- Artificial Neural Network model and its application to the prediction of groundwater level fluctuations

Accurate groundwater level modeling and forecasting contribute to civil projects, land use, citys planning and water resources management. Combined Wavelet-Artificial Neural Network (WANN) model has been widely used in recent years to forecast hydrological and hydrogeological phenomena. This study investigates the sensitivity of the pre-processing to the wavelet type and decomposition level in ...

Communications and neural networks: theory and practice

In this paper we shall see that neural networks and communications are interlinked in a number of ways, towards the goal of e cient communication of information. One concrete example of this is the use of neural networks to ensure e cient use of communication channels, through connection admission control in ATM networks. In addition, however, e cient communication is also important within a de...
