Using Information Gain Attribute Evaluation to Classify Sonar Targets

نویسنده

  • Jasmina Novakovic
چکیده

This paper presents an application of Information Gain (IG) attribute evaluation to the classification of the sonar targets with C4.5 decision tree. C4.5 decision tree has inherited ability to focus on relevant features and ignore irrelevant ones, but such method may also benefit from independent feature selection. In our experiments, IG attribute evaluation significantly improves C4.5 decision tree. This research also shows that feature selection helps increase computational efficiency while improving classification accuracy.

Training Radial Basis Function Neural Network using Stochastic Fractal Search Algorithm to Classify Sonar Dataset

Radial Basis Function Neural Networks (RBF NNs) are one of the most applicable NNs in the classification of real targets. Despite the use of recursive methods and gradient descent for training RBF NNs, classification improper accuracy, failing to local minimum and low-convergence speed are defects of this type of network. In order to overcome these defects, heuristic and meta-heuristic algorith...

Natural Dolphin Echo Recognition Using an Integrator Gateway Network

We have been studying the performance of a bottlenosed dolphin on a delayed matching-to-sample task to gain insight into the processes and mechanisms that the animal uses during echolocation. The dolphin recognizes targets by emitting natural sonar signals and listening to the echoes that return. This paper describes a novel neural network architecture, called an integrator gateway network, tha...

Clutter Removal in Sonar Image Target Tracking Using PHD Filter

In this paper we have presented a new procedure for sonar image target tracking using PHD filter besides K-means algorithm in high density clutter environment. We have presented K-means as data clustering technique in this paper to estimate the location of targets. Sonar images target tracking is a very good sample of high clutter environment. As can be seen, PHD filter because of its special f...

Scanned monocular sonar and the doorway problem

A sonar system is presented that relies on scanning a single ultrasonic transducer and measuring echo amplitude and arrival times. Bearing angles to targets are estimated far more accurately than the transducer beamwidth as obtained with conventional sonar rings based on the Polaroid ranging module. A Gaussian beam characteristic is fitted using least squares to the amplitudes of corresponding ...

Underwater Source-Level Estimation using Sparsity-Cognizant Source-Location Mapping

In this work, we present a method to estimate the acoustic source gain of targets in a shallow-water environment, using passive sonar. This is accomplished by using a two-step approach. The first step is to localize the target, which is accomplished by using the Sparsity-Cognizant Source Location Mapping (scSLM) algorithm, developed at the Space and Naval Warfare Systems Center Pacific. This al...
