AN INVARIANT PATTERN-RECOGNITION MACHINE USING A MODIFIED ART ARCHITECTURE
Abstract A novel invariant pattern recognition machine is proposed based on a modified ART architecture. Invariance is achieved by adding a new layer called F23, beyond the F2 layer in the ART architecture. The design of the weight ...

TOWARDS AN ART BASED MATHEMATICAL EDITOR, THAT USES ONLINE HANDWRITTEN SYMBOL RECOGNITION
Abstract A new mathematical editor, based on the recognition of run-on discrete handwritten symbols, is proposed. The tested laboratory prototype of the system, modular and adaptable to the user habits and site requirements, uses a ...

On-line recognition of cursive Korean characters using neural networks
Abstract This paper proposes an efficient method for on-line recognition of cursive Korean characters. Since Korean characters are composed of two or three graphemes in two dimensions, strokes, primitive components of the characters, ...

On-line Chinese character recognition using ART-based stroke classification
Abstract This paper proposes an on-line Chinese character recognition method using Adaptive Resonance Theory (ART) based stroke classification. Strokes, primitive components of Chinese characters, are usually warped into a cursive ...
