Both methods are used to find the optimum weights for the hidden and output layers of feedforward artificial neural network (ANN) model. Each algorithm is presented in separate module and we proposed three different types of Dynamic Connection Strategies (DyConS) for combining both algorithms to improve the recognition performance of spoken Malay speech recognition. Two different GA techniques are used in this research: a mutated GA technique is proposed and compared with the standard GA technique. One hundred experiments with 5000 words are conducted using the proposed DyConS. Owing to previous facts, GA combined with ANN proved to attain certain advantages with sufficient recognition performance. Thus, from the results, it was observed that the performance of mutated GA algorithm when combined with CG is better than standard GA and CG models. Integrating the GA with feed-forward network improved mean square error (MSE) performance and with good connection strategy by this two stage training scheme, the recognition rate is increased up to 99%.","PeriodicalId":88960,"journal":{"name":"Proceedings of the ...

The problem of modeling of time-varying frequency spectrum in the context of PLC is addressed and a novel solution is proposed for tracking and using the temporal motion of spectral flow. The proposed PLC utilizes a time-frequency motion (TFM) matrix representation of the audio signal where each frequency is tagged with a motion vector estimate. The spectral motion vectors are estimated by cross-correlating the movement of spectral energy within sub-bands across time frames. The missing packets are estimated in TFM domain and inverse transformed to the time-domain. In order to compare the proposed method with common approaches, objective performance evaluation of speech quality (PESQ), and subjective listening test in terms of MOS scores are conducted in a range of packet loss from 5% to 20%. The results demonstrate that the proposed algorithm improves performance compared to a number of benchmark methods including that of the ITU.","PeriodicalId":88960,"journal":{"name":"Proceedings of the ...

Typical approaches towards secure embedded systems employ dedicated modules, such as ASICs, co-processors, and accelerators, to implement these functions and optimize these hardware modules for the adopted algorithms. In our work, we analyze performance and power trade-offs of typical cryptographic algorithms (DES, AES, and RSA) when executed in processing elements that constitute typical embedded processors. Our goal is to characterize and optimize, performance-wise and power-wise, the sources of inefficiency when the encryption/decryption operations are executed in general purpose embedded processors with different processing and caching capabilities. Our analysis focuses on three major parameters: the parallelism of the core (issue width and size of execution window), voltage and frequency switching in the core, and size of the last-level cache (LLC). Those parameters constitute the major power-consumption contributors in all modern embedded general purpose processors. Our results demonstrate that cryptographic operations can be performed efficiently, in terms of both performance and power consumption, for specific values of the analyzed parameters, indicating that reconfigurable approaches can dynamically optimize processor organization and ameliorate the reported performance and power figures in the context of general purpose embedded processors.","PeriodicalId":88960,"journal":{"name":"Proceedings of the ...

Objective methods for assessing perceptual image quality are important for many image processing applications, such as monitoring and controlling image quality for quality control systems, benchmarking image processing systems and so on. The novel image quality metric proposed in this paper uses a relatively small number of pair-wise intensity comparisons to represent a patch as binary string, then compares corresponding patches using Hamming distances. It then calculates a dissimilarity value between images as an average of the Hamming distances computed between patches. The proposed metric is more consistent with human visual system and thus outperforms other existing and widely used metrics, namely the root mean square error (RMSE) and structural similarity index (SSIM). The computational cost of the proposed metric is also less compared to the state-of-the-art method.","PeriodicalId":88960,"journal":{"name":"Proceedings of the ...
