This dataset consists of features of handwritten numerals (‘0’–‘9’) (K=10) extracted from a collection of Dutch utility maps.
Two hundred patterns per class (for a total of 2,000 (=N) patterns)
have been digitized in binary images.
Raw observations are 32x45 bitmmaps, which are divided into
nooverlapping blocks of 2x3 and the number of pixels are counted in
This generate p=240 (16x15) variable, recodring the
normalized counts of pixels in each block and each element is an
integer in the range 0 to 6.
DutchUtility contains the true digits and
colnames of it contains the position of the block matrix, from which the normalized counts of pixels are taken.
A scalar containing integers between 1 and 2000.
Specify the size of the title text with a numeric value of length 1.
