Interpolating Vectors for Robust Pattern Recognition
Kunihiko Fukushima, Isao Hayashi (Kansai Univ.)
Abstract (in Japanese) (See Japanese page) 
(in English) This paper proposes a powerful algorithm for pattern recognition, which uses \textit{interpolating vectors} for classifying patterns. The basic idea of the algorithm is as follows. Labeled reference vectors in a multi-dimensional feature space are first produced by a kind of competitive learning. We then assume a situation where interpolating vectors are densely placed along line segments connecting all pairs of reference vectors of the same label. From these interpolating vectors, we choose the one that has the largest similarity to the test vector. The label of the chosen vector is taken as the result of pattern recognition. In practice, we can get the same result with a simpler process.
We applied this method to the neocognitron for handwritten digit recognition and reduced the error rate from 1.52% to 1.02% for a blind test set of 5000 digits.
The use of interpolating vectors is not limited to the neocognitron but can be applied to various systems for pattern recognition.
