This paper describes the development of an algorithm for verification signatures written on a touch-sensitive pad. The signature is based artificial neural network. novel network presented here, called “Siamese” time delay network, consists two identical networks joined at their output. During training learns to measure similarity between pairs signatures. When used verification, only one half Siamese evaluated. output this feature vector input signature. Verification comparing with stored...
The architecture, implementation, and applications of a special-purpose neural network processor are described. chip performs over 2000 multiplications additions simultaneously. Its data path is particularly suitable for the convolutional topologies that typical in classification networks, but can also be configured fully connected or feedback topologies. Resources multiplexed to permit implementation networks with several hundreds thousands connections on single chip. Computations performed...
A neural network with 136000 connections for recognition of handwritten digits has been implemented using a mixed analog/digital chip. The chip is capable processing 1000 characters/s. system essentially the same rate (5%) as simulation 32-b floating-point precision.
The Euclid telescope, due for launch in 2021, will perform an imaging and slitless spectroscopy survey over half the sky, to map baryon wiggles weak lensing. During is expected resolve 100,000 strong gravitational lens systems. This ideal find rare configurations, provided they can be identified reliably on a reasonable timescale. For this reason we have developed Convolutional Neural Network (CNN) that used identify images containing lensing CNNs already been image digit classification as...
ABSTRACT We investigate the ability of human ‘expert’ classifiers to identify strong gravitational lens candidates in Dark Energy Survey like imaging. recruited a total 55 people that completed more than 25 per cent project. During classification task, we present participants 1489 images. The sample contains variety data including simulations, real lenses, non-lens examples, and unlabelled data. find experts are extremely good at finding bright, well-resolved Einstein rings, while arcs with...
ABSTRACT Forthcoming large imaging surveys such as Euclid and the Vera Rubin Observatory Legacy Survey of Space Time are expected to find more than 105 strong gravitational lens systems, including many rare exotic populations compound lenses, but these systems will be interspersed among much larger catalogues ∼109 galaxies. This volume data is too for visual inspection by volunteers alone feasible lenses only appear in a small fraction which could cause amount false positives. Machine...
A neural network algorithm-based system that reads handwritten ZIP codes appearing on real US mail is described. The uses a recognition-based segmenter, hybrid of connected-components analysis (CCA), vertical cuts, and recognizer. Connected components are single digits handled by CCA. CCs combined or dissected the vertical-cut segmenter. four main stages processing preprocessing, in which noise removed deslanted, CCA segmentation recognition, vertical-cut-point estimation segmentation,...
We investigate the constraints on models of supermassive black hole (SMBH) and quasar formation obtainable from two recent observational developments: discovery luminous quasars at z~6, estimates local mass density SMBHs. If ~90 per cent this was accreted redshifts z<3, as suggested by observed luminosity functions, these joint pose a challenge for models, which must account population z~6 within very limited `mass budget'. class based hierarchical structure scenario, in major mergers...
Education is a major force for economic and social wellbeing. Despite high aspirations, education at all levels can be expensive ineffective. Three Grand Challenges are identified: (1) enable people to learn orders of magnitude more effectively, (2) less cost, (3) demonstrate success by exemplary interdisciplinary in complex systems science. A ten year ‘man-on-the-moon’ project proposed which FuturICT’s unique combination Complexity, Social Computing Sciences could provide an urgently needed...
Wide-field sub-millimetre surveys have driven many major advances in galaxy evolution the past decade, but without extensive follow-up observations coarse angular resolution of these limits science exploitation.
