Available in PDF, EPUB and Kindle. Book excerpt: This report describes tools for simulating complex non-speech time series data of the type received by a hydrophone and a backpropagation artificial neural network for classifying the data. These tools can be used to investigate the utility of applying neural networks to the classification of passive sonar data. The tools use the Cmusic sound synthesis program for simulating the sounds received by a hydrophone. The neural network has three user interfaces, one graphical and two in the TTY mode for running experiments and on multiple platforms. The report includes a review of the artificial neural network approach, description of the neural network methods and tools, and an outline of the simulation of passive sonar signals.

Available in PDF, EPUB and Kindle. Book excerpt: This report describes initial steps taken to build a model of a natural acoustic source and to develop in parallel a neural network architecture capable of discriminating features of this source. The steps described include: synthesis of sounds to simulate ten sonar target sources; selection of a feed-forward neural network; examination of a variety of parameters with no-noise target signals to determine the best networks for solving the problem (target classification and speed estimates); and evaluation of the neural network performance with noisy input signals. Different types of Fourier pre-processing and network parameters were examined for their effects on convergence rate (learning speed) and classification performance. Finally, the extension of this work to real passive sonar data is discussed.

Download or read book Biomimetic Spike based Algorithms and Hardware for Sound Classification Localization and Speech Recognition written by Yirong Pu and published by . This book was released on 2011 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The objective of the thesis work is to design real-time, spike-based algorithms and implementation for biomimetic sound processing systems. An acoustic direction finding (ADF) system was designed and implemented in hardware to process transient sounds. Additionally, a top-down attentional mechanism model based on a study of mammalian brain activity was designed and explored to improve speech recognition. The front-end of the ADF system, which mimics a mammalian peripheral auditory system, generates spiking neuron firings as its output. The back-end algorithm was developed in MATLAB and an FPGA-based neural network was its final embodiment. The algorithm accomplishes sound detection, classification, direction finding, and localization of various kinds of audio data under noisy conditions and from reverberant environments. The attentional model was integrated with the front-end processing to help segregate a target sound source from masker sound sources as well as improving the classification accuracy of the target source. The neural-network-based sound classification and localization algorithm was first developed and tested using weaponry sound data obtained in the field. The algorithm is able to differentiate and trace various gunfire acoustic signatures in the presence of high background noise. The algorithm can locate the sound source by using single or multiple microphone array sites. Compared to a least square time difference of arrival algorithm, the neural-network-based algorithm has higher detection rate and more accurate localization. The complete back-end processing system was implemented on a single Xilinx Virtex-5 FPGA chip. The neural-network-based algorithm was also modified for a frog habitat monitoring application to demonstrate that the algorithm can be useful for applications other than weaponry classification and localization. Literature was reviewed and a functional, biologically-based, top-down attentional model was formulated, coded, and tested using speech signals with varying target masker ratios. The model improves the correctness of word identification of target speech by up to 50% in a noisy environment when the masker source is either a white noise signal or a speech- like signal. The thesis work presents the first spike-based transient sound classification and localization algorithm using neural networks, the first spike-based frog habitat monitoring algorithm, and a novel top-down, biologically-based attentional model.

This book was released on 2012-12-06 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 36 (thesis year 1991) a total of 11,024 thesis titles from 23 Canadian and 161 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 36 reports theses submitted in 1991, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.
