Acoustic classification of zooplankton
Work on the forward problem in zooplankton bioacoustics has resulted in the identification of three categories of acoustic scatterers: elastic-shelled (e.g. pteropods), fluid-like (e.g. euphausiids), and gas-bearing (e.g. siphonophores). The relationship between backscattered energy and animal …

Acoustic classification of buried objects with mobile sonar platforms
… platforms is investigated for the purpose of acoustically classifying compact objects on or below the seabed. The extension of existing strategies, including synthetic aperture sonar and conventional imaging, are explored within the context of the buried object problem. In particular, the need …

Speech-Based Artificial Intelligence Emotion Biomarkers in Frontotemporal Dementia
Acoustic speech markers are well-characterized in Frontotemporal Dementia (FTD), a heterogeneous spectrum of progressive neurodegenerative diseases that can affect speech production and comprehension as well as higher-order cognition, behavior, and motor control. While profound apathy and deficits …

Examining Individual Identity in Beluga Whale (Delphinapterus leucas) Acoustic Repertoires as a Function of Call Type
… rather than inferring meaning from automated acoustic classification, our study links call structure to receiver-based processes that underlie individual vocal recognition. These findings provide the first experimental evidence that belugas discriminate between individual callers across their …

Acoustic Approaches to Gender and Accent Identification
… This presents a tougher problem for traditional classification techniques. In this thesis, we propose and evaluate a number of techniques for gender and accent classification. These techniques are novel modifications and extensions to state of the art algorithms, and they result in enhanced …

Beyond LiDAR for Unmanned Aerial Event-Based Localization in GPS Denied Environments
… for providing situational awareness using both acoustic ground sensors and aerial sensing modalities. Ground sensors in the field of data-driven detection and classification approaches typically rely on computationally expensive inputs such as image or video-based methods [6, 91]. However, the …
