State-Clustering Based Multiple Deep Neural Networks Modeling Approach for Speech Recognition

2015 · IEEE/ACM Transactions on Audio Speech and Language Processing

The hybrid deep neural network (DNN) and hidden Markov model (HMM) has recently achieved dramatic performance gains in automatic speech recognition (ASR). The DNN-based acoustic model is very powerful but its learning process is extremely …

Research on the Modified Shifted Rayleigh Mixture Filter and Its Use on Bearings-Only Maneuvering Target Tracking

2015 · Journal of Jiangxi Normal University

The modified shifted Rayleigh mixture filter is introduced for bearings-only maneuvering targets tracking,which use Gaussian mixture reduction method based on cost-function to improve the shifted Rayleigh mixture filter.The MSRMF is based on jump Markov linear …
