We previously proved that restoring the instantaneous amplitude as well as instantaneous phase on the output from Gammatone filterbank plays a significant role in speech enhancement. However, dereverberation is still a challenge since the previously proposed scheme can only work in noisy environments. In this paper, we extend our previously proposed scheme to general speech enhancement for removing...
This paper proposes a robust front-end for speech applications based on restoration scheme of instantaneous amplitude and phase. Typical applications such as hearing aids and automatic speech recognition systems still have challenging issues with regard to robustness against noise and reverberation. The proposed front-end employed a combination of our previously proposed method for restoring instantaneous...
For software quality assurance, software defect prediction (SDP) has drawn a great deal of attention in recent years. Its goal is to reduce verification cost, time and effort by predicting the defective modules efficiently. In SDP, proper attribute selection plays a significant role. However, selection of proper attributes and their representation in an efficient way are very challenging due to the...
We have proved that restoring the instantaneous amplitude as well as instantaneous phase on Gammatone interbank plays a significant role for speech enhancement. However, it is still challenging topic with dereverberation since previously proposed scheme can only work in noisy environments. In this paper, we extend our previously proposed scheme to be general speech enhancement of removing the effects...
Feedback data loss can severely degrade the overall system performance and as well as it can affect the control and computation of the cyber-physical systems (CPS) in the provision of real-time, efficient, dependable, safe, and secure operations of a wide range of emerging applications. In CPS applications, a wide range of data patterns are observed in different applications which make a great challenge...
This paper proposes a restoration scheme for the instantaneous amplitudes and phases in sub-bands by using a Kalman filter with linear prediction (LP). A few important studies have already proved that the phase spectrum in the short-time Fourier transform plays an important role in speech enhancement. Thus, the proposed scheme concentrates on simultaneously restoring both instantaneous amplitudes...
This paper proposes a restoration scheme for the instantaneous amplitudes and phases in sub-bands by using a Kalman filter with linear prediction (LP). A few important studies have already proved that phase spectrum on the short term Fourier transform plays an important role in speech enhancement. Thus, the proposed scheme concentrates on restoring of both the instantaneous amplitudes and phases simultaneously...
Feedback loss can severely degrade the overall system performance, in addition, it can affect the control and computation of the Cyber-physical Systems (CPS). CPS hold enormous potential for a wide range of emerging applications including stochastic and time-critical traffic patterns. Stochastic data has a randomness in its nature which make a great challenge to maintain the real-time control whenever...
Feedback data loss can severely degrade the overall system performance and as well as it can affect the control and computation of the Cyber-physical System (CPS). Therefore, incomplete feedback makes a great challenge in any uncertain condition to maintain the real-time control of the CPS. In this paper, we propose a data recovery scheme, called Efficient spatial data recovery (ESDR) scheme for CPS...
Heterogeneous wireless network pose many interesting research challenges. Among them, resource management and load balancing in such a hybrid environment is still an open problem. Consider these issues an efficient semi distributed load balancing architecture for multiple access networks is introduced in this paper. Since both centralize and distributed architecture has their own pros and cons, in...
