Call admission control algorithms that reduce dropped calls in CDMA cellular systems are discussed in this paper. The capacity of a CDMA system is con ned by interference of users from both inside and outside of the target cell. Earlier algorithms for call admission control is based on the e ective traÆc load for the target cell if one call is accepted. These algorithms ignore the interference ...

There has been much interest in increasing the computational power of neural networks. In addition there has been much interest in “designing” neural networks to better suit particular problems. Increasing the “order” of the connectivity of a neural network permits both. Though order has played a significant role in feedforward neural networks, it role in dynamically driven recurrent networks i...

Convolutional and bidirectional recurrent neural networks have achieved considerable performance gains as acoustic models in automatic speech recognition in recent years. Latest architectures unify long short-term memory, gated recurrent unit and convolutional neural networks by stacking these different neural network types on each other, and providing short and long-term features to different ...

Representation learning over dynamic graphs has attracted much attention because of its wide applications. Recently, sequential probabilistic generative models have achieved impressive results they can model data distributions. However, modeling the distribution is still extremely challenging. Existing methods usually ignore mutual interference stochastic states and deterministic states. Beside...

In this paper, we introduced a new framework of speech recognizer based on HMM and neural net. Unlike the traditional hybrid system, the neural net was used as a post processor, which classify the speech data segmented by HMM recognizer. The purpose of this method is to improve the top-choice accuracy of HMM based speech recognition system in our lab. Major issues such as how to use the segment...

Though the time-delay neural net architecture has been recently used in a number of speech recognition applications, it has the problem that it can not use longer temporal contexts because this increases the number of connection weights in the network. This is a serious bottleneck because the use of larger temporal contexts can improve the recognition performance. In this paper, a time-derivari...

This paper proposes an approach to construct a better Semantic Perceptron Net (SPN) used for topic spotting. To accomplish this task a learning paradigm call: neural network ensembling is used. Applying this technique to the original structure of Semantic Perceptron Net a new system called GA-SPN (Genetic Algorithm based Semantic Perceptron Net) was developed. The new system uses a neural netwo...
