Semi-Automated Nasal PAP Mask Sizing using Facial Photographs

no code implementations21 Sep 2017 Benjamin Johnston, Alistair McEwan, Philip de Chazal

We present a semi-automated system for sizing nasal Positive Airway Pressure (PAP) masks based upon a neural network model that was trained with facial photographs of both PAP mask users and non-users.

Turn Down that Noise: Synaptic Encoding of Afferent SNR in a Single Spiking Neuron

no code implementations11 Nov 2014 Saeed Afshar, Libin George, Jonathan Tapson, Andre van Schaik, Philip de Chazal, Tara Julia Hamilton

We have added a simplified neuromorphic model of Spike Time Dependent Plasticity (STDP) to the Synapto-dendritic Kernel Adapting Neuron (SKAN).

Learning ELM network weights using linear discriminant analysis

no code implementations12 Jun 2014 Philip de Chazal, Jonathan Tapson, André van Schaik

We present an alternative to the pseudo-inverse method for determining the hidden to output weight values for Extreme Learning Machines performing classification tasks.

Explicit Computation of Input Weights in Extreme Learning Machines

no code implementations11 Jun 2014 Jonathan Tapson, Philip de Chazal, André van Schaik

In the absence of supervised training for the input weights, random linear combinations of training data samples are used to project the input data to a higher dimensional hidden layer.
