Ga. Carpenter et Wd. Ross, ART-EMAP - A NEURAL-NETWORK ARCHITECTURE FOR OBJECT RECOGNITION BY EVIDENCE ACCUMULATION, IEEE transactions on neural networks, 6(4), 1995, pp. 805-818
A new neural network architecture is introduced for the recognition of
pattern classes after supervised and unsupervised learning. Applicati
ons include spatio-temporal image understanding and prediction and thr
ee dimensional (3-D) object recognition from a series of ambiguous two
dimensional views, The architecture, called ART-EMAP, achieves a synt
hesis of adaptive resonance theory (ART) and-spatial and temporal evid
ence integration for dynamic predictive mapping (EMAP), ART-EMAP exten
ds the capabilities of fuzzy ARTMAP in four incremental stages, Stage
1 introduces distributed pattern representation at a view category fie
ld, Stage 2 adds a decision criterion to the mapping between view and
object categories, delaying identification of ambiguous objects when f
aced with a low confidence prediction. Stage 3 augments the system wit
h a field where evidence accumulates in medium-term memory, Stage 4 ad
ds an unsupervised learning process to fine-tune performance after the
limited initial period of supervised network training, Each ART-EMAP
stage is illustrated with a benchmark simulation example, using both n
oisy and noise-free data. A concluding set of simulations demonstrate
ART-EMAP performance on a difficult 3-D object recognition problem.
