- Statistical adaptive classifier for handwriting: takes vectors of features, trains self to data base by finding best (lowest error confusion) weighting
- Data base collections: most are too small ("greenhouse data sets"), therefore low accuracy
- Formal training of user not acceptable for handwriting recognition
- 7000 and 30000 character collections from handwriting "back-room" forms not large enough
- Pre-processing of handwriting before recognition: scaling, shear normalization (tilt),
- Using too many feature measurements can lower performance, since the probability is higher that some features are of low effectiveness
- Gives actual/typical substitution errors from data collection on handwriting recognition
