The problem of classification of underwater targets from the acoustic backscattered signals is considered in this paper. A wavelet packet-based feature extraction scheme is used in conjunction with the linear prediction coding scheme as the front-end-processor. Selected features with higher discriminatory power are then fed to a neural network Cited by: 5.

understanding how the input flows to the output in back propagation neural network with the calculation of values in the network. the example is taken from below link refer this https://mattmazur. You can certainly use a CNN to classify a 1D signal. Since you are interested in sleep stage classification see this a deep neural network called the DeepSleepNet, and uses a combination of 1D convolutional and LSTM layers to classify EEG signals into sleep stages.
I want to solve a classification problem with 3 classes using multi layer neural network with back propagation algorithm. I'm using matlab a. I'm facing trouble with newff function. I want to build a network with one hidden layer and there will be 3 neurons in the output layer, one for each class. Please advise me with example. Here is my code. For underwater target classification which is supposed to recognise different ships with the radiated acoustic signal, it is the most challenging task to provide excellent classification accuracy in a variety of environments. However, most of the existing systems are optimised to get the best performance on the data set from certain situations which they are trained in, which Author: Xu Cao, Xiaomin Zhang, Roberto Togneri, Yang Yu.

Two types of classifiers are investigated and compared: Classification Trees (CT) and Back-propagation neural network (BP NN). Classification experiments conducted on synthetic and real-world underwater signals show that: (1) the Power feature extraction method is more robust to time synchronization issues than the LDB scheme is; (2) the MS NN scheme is a successful dimension reduction scheme that may be used Author: Ozhan Duzenli.
Classification of underwater signals using a back. This paper concerns classification of underwater passive sonar signals radiated by ships using neural networks. Classification process can be divided into two stages: one is the signal preprocessing and feature extraction, the other is the recognition process.
Therefore, intelligent classification of underwater signals significantly reduces the burden on the operators , , . In recent decades, the deployment of neural network. The classifier is a feed-forward neural network having one hidden layer and one output layer, and a back propagation algorithm is used to update the weighting vector of each layer.
Experimental results with underwater transient signals demonstrate that the proposed method is very promising for classification of underwater transient : LimTaegyun, BaeKeunsung, HwangChansik, LeeHyeonguk.
A Back Propagation neural networks is applied to perform a real-time classification of the input image pixels into two different classes corresponding to sealine edge or other regions. A new method for classification of analogue and digital modulated signals at low signal-to-noise ratio (SNR) is introduced in this paper.
This method uses the statistical signal characterization (SSC) to extract parameters to classify the different modulation by: Classification of EEG signals using multiple gait features based on Small-world Neural Network Abstract: In this paper, a novel classification method among running, walking and standing by combining common spatial patterns (CSP) and the fastICA feature extraction method together and constructing a Small-world Neural Network(SWNN, for short.

SONAR Systems and Underwater Signal Processing: Classic and Modern Approaches SONAR systems, the measured signals, known as contacts, are reflected either from targets or from other undesired sources.
In the latter case, the measured signal is known as a false alarm or clutter as mentioned Size: 1MB. We propose in this paper to use the convolutional neural network AlexNet with transfer learning for automatic fish species classification.
We extract features from foreground fish images of the available underwater dataset using the pretrained AlexNet network either with or without fine-tunig. For classification, we use a linear SVM by: 1.
The neural network will output the probability of this case being class number 1 vs the rest of the classes. Afterwords, you have to assign as positive another class, e.g.
number 2, assign all other classes as one big negative class and get the predicted probability from the network again. Abstract: This paper proposes a technique using discrete wavelet transform (DWT) and back-propagation neural network (BPNN) to identify the fault types on single circuit transmission lines.
The ATP/EMTP is used to simulate fault signals. The mother wavelet daubechies4 (db4) is employed to decompose high frequency component from these signals. The networks from our chapter Running Neural Networks lack the capabilty of learning.
They can only be run with randomly set weight values. So we cannot solve any classification problems with them. However, the networks in Chapter Simple Neural Networks were capable of learning, but we only used linear networks for linearly separable classes.
