Leg motion classification with artificial neural networks using wavelet-based features of gyroscope signals

Ayrulu-Erdem, B.; Barshan, B. (2011)

We extract the informative features of gyroscope signals using the discrete wavelet transform (DWT) decomposition and provide them as input to multi-layer feed-forward artificial neural networks (ANNs) for leg motion ...
Neural networks for improved target differentiation and localization with sonar

Ayrulu, B.; Barshan, B. (Pergamon Press, 2001)

This study investigates the processing of sonar signals using neural networks for robust differentiation of commonly encountered features in indoor robot environments. Differentiation of such features is of interest for ...
Transform pre-processing for neural networks for object recognition and localization with sonar

Barshan, Billur; Ayrulu, Birsel (SPIE, 2003)

We investigate the pre-processing of sonar signals prior to using neural networks for robust differentiation of commonly encountered features in indoor environments. Amplitude and time-of-flight measurement patterns acquired ...
