Correcting Errors in Optical Data Transmission Using Neural Networks
Hunt, S.; Sun, Yi.; Shafarenko, A.; Adams, R.G.; Davey, N.; Slater, B.; Bhamber, R.; Boscolo, S.; Turitsyn, S.K. (2010)Optical data communication systems are prone to a variety of processes that modify the transmitted signal, and contribute errors in the determination of 1s from 0s. This is a difficult, and commercially important, problem ... -
Dendritic Morphology Predicts Pattern Recognition Performance in Multi-compartmental Model Neurons with and without Active Conductances
De Sousa, Giseli; Maex, Reinoud; Adams, R.G.; Davey, N.; Steuber, Volker (2015-04-01)In this paper we examine how a neuron’s dendritic morphology can affect its pattern recognition performance. We use two different algorithms to systematically explore the space of dendritic morphologies: an algorithm that ... -
Detecting partial occlusion of humans using snakes and neural networks
Tabb, Ken; Davey, N.; George, S.; Adams, R.G. (1999)This paper summarises the development of a computer system designed to detect moving humans in an image or series of images. The system combines the use of active contour models, ‘snakes’, which detect human objects in an ... -
Determinants of associative memory performance in spiking and non-spiking neural networks with different synaptic plasticity regimes
Metaxas, A.; Maex, Reinoud; Adams, R.G.; Steuber, Volker; Davey, N. (2012)Poster presented at CNS 2012 -
Determinants of pattern recognition by cerebellar Purkinje cells
De Sousa, Giseli; Adams, R.G.; Davey, N.; Steuber, Volker (2008)Poster presented at CNS 2008 -
The development of iHARP: a multiple instruction issue processor chip
Steven, G.B.; Adams, R.G.; Findlay, P.; Trainis, S.A. (Institute of Electrical and Electronics Engineers (IEEE), 1991)During the last decade RISC ideas on processor architecture have become widely accepted. RISC architectures achieve significant performance advantages over CISC architectures by striving to execute one instruction per ... -
Developmental artificial neural networks for shape recognition: a model of the retina
Rust, A.G.; George, S.; Bolouri, H.; Adams, R.G. (University of Hertfordshire, 1996)There has been recent interest in mimicking the self-organising processes of biological development to design artificial neural networks. An a priori decision must however be made as to the degree of biological detail ... -
Developmental evolution of an edge detecting retina
Rust, A.G.; Adams, R.G.; George, S.; Bolouri, H. (Springer Nature, 1998) -
Developmental evolution of dendritic morphology in a multi-compartmental neuron model
Rust, A.G.; Adams, R.G. (IEE, 1999)Through the use of a multi-compartmental neuron simulation, Mainen and Sejnowski demonstrated that spike generation in neurons is a function of their dendritic structure [l]. In this paper we investigate the determination ... -
The effect of dendritic morphology on pattern recognition in the presence of active conductances
De Sousa, Giseli; Maex, Reinoud; Adams, R.G.; Davey, N.; Steuber, Volker (2011)Poster presented at CNS 2011 -
The Effect of Different Forms of Synaptic Plasticity on Pattern Recognition in the Cerebellar Cortex
de Sousa, G.; Adams, R.G.; Davey, N.; Maex, R.; Steuber, Volker (2009)Many cerebellar learning theories assume that long-term depression (LTD) of synapses between parallel fibres (PFs) and Purkinje cells (PCs) provides the basis for pattern recognition in the cerebellum. Previous work has ... -
The effect of non-specific LTD on pattern recognition in cerebellar Purkinje cells
Safaryan, Karen; Maex, Reinoud; Adams, R.G.; Davey, N.; Steuber, Volker (2010)Poster presented at CNS 2010 -
Efficient architectures for sparsely-connected high capacity associative memory models
Calcraft, L.; Adams, R.G.; Davey, N. (2007) -
Efficient connection strategies in 1D and 2D associative memory models with and without displaced connectivity
Calcraft, L.; Adams, R.G.; Davey, N. (2008)This study examines the performance of sparsely connected associative memory models built using a number of different connection strategies, applied to one- and two-dimensional topologies. Efficient patterns of connectivity ... -
Encoding sensory information in spiking neural network for the control of autonomous agents
Oros, N.; Adams, R.G.; Davey, N.; Cañamero, Lola; Steuber, Volker (2008)The goal of the work presented here was to find a model of a spiking sensory neuron that could cope with small variations of a simulated pheromone concentration and also the whole range of concentrations. We tried many ... -
Evolution of bilateral symmetry in agents controlled by spiking neural networks
Oros, N.; Steuber, Volker; Davey, N.; Cañamero, Lola; Adams, R.G. (Institute of Electrical and Electronics Engineers (IEEE), 2009)We present in this paper three novel developmental models allowing information to be encoded in space and time, using spiking neurons placed on a 2D substrate. In two of these models, we introduce neural development that ... -
Evolution of bistable dynamics in spiking neural controllers for agents performing olfactory attraction and aversion

Evolution of developmental ontogeny for robustly reproducible phenotypes
Rust, A.G.; Adams, R.G.; George, S.; Bolouri, H. (University of Hertfordshire, 1998)Development has been used by a number of researchers as an efficient means of nonlinearly decoding genetic information is evolutionary systems. We show that developmental routines which do not utilise cell-cell interactions ...
