The Reciprocal tau-Cell: A Log-Domain Circuit for On-Chip Learning
Craig Jin, Thomas Chaffey
Training hardware by gradient descent requires a gradient to be computed using a separate backwards pass. If a circuit is reciprocal, meaning every connection is symmetric, the bac…
Improving spatial cues for hearables using a parameterized binaural CDR estimator
Reza Ghanavi, Craig Jin
We investigate a speech enhancement method based on the binaural coherence-to-diffuse power ratio (CDR), which preserves auditory spatial cues for maskers and a broadside target. C…
Improved multipath time delay estimation using cepstrum subtraction
Eric L. Ferguson, Stefan B. Williams, Craig T. Jin
When a motor-powered vessel travels past a fixed hydrophone in a multipath environment, a Lloyd's mirror constructive/destructive interference pattern is observed in the output spe…
Sound Source Localization in a Multipath Environment Using Convolutional Neural Networks
Eric L. Ferguson, Stefan B. Williams, Craig T. Jin
The propagation of sound in a shallow water environment is characterized by boundary reflections from the sea surface and sea floor. These reflections result in multiple (indirect)…
Convolutional Neural Networks for Passive Monitoring of a Shallow Water Environment using a Single Sensor
Eric L. Ferguson, Rishi Ramakrishnan, Stefan B. Williams +1
A cost effective approach to remote monitoring of protected areas such as marine reserves and restricted naval waters is to use passive sonar to detect, classify, localize, and tra…
Spherical Harmonic Signal Covariance and Sound Field Diffuseness
Nicolas Epain, Craig T. Jin
Characterizing sound field diffuseness has many practical applications, from room acoustics analysis to speech enhancement and sound field reproduction. In this paper we investigat…
Large Deformation Diffeomorphic Metric Mapping And Fast-Multipole Boundary Element Method Provide New Insights For Binaural Acoustics
Reza Zolfaghari, Nicolas Epain, Craig T. Jin +2
This paper describes how Large Deformation Diffeomorphic Metric Mapping (LDDMM) can be coupled with a Fast Multipole (FM) Boundary Element Method (BEM) to investigate the relations…
A First-Order Non-Homogeneous Markov Model for the Response of Spiking Neurons Stimulated by Small Phase-Continuous Signals
J. Tapson, C. Jin, A. van Schaik +1
We present a first-order non-homogeneous Markov model for the interspike-interval density of a continuously stimulated spiking neuron. The model allows the conditional interspike-i…
