+Data Set Information:
+
+
+1593 handwritten digits from around 80 persons were scanned, stretched 
+in a rectangular box 16x16 in a gray scale of 256 values.Then each pixel 
+of each image was scaled into a bolean (1/0) value using a fixed 
+threshold.
+
+Each person wrote on a paper all the digits from 0 to 9, twice. The 
+commitment was to write the digit the first time in the normal way 
+(trying to write each digit accurately) and the second time in a fast 
+way (with no accuracy).
+
+The best validation protocol for this dataset seems to be a 5x2CV, 50% 
+Tune (Train +Test) and completly blind 50% Validation.

+
+Attribute Information:
+
+This dataset consists of 1593 records (rows) and 256 attributes 
+(columns).
+
+Each record represents a handwritten digit, orginally scanned with a 
+resolution of 256 grays scale (28).
+
+Each pixel of the each original scanned image was first stretched, and 
+after scaled between 0 and 1 (setting to 0 every pixel whose value was 
+under tha value 127 of the grey scale (127 included) and setting to 1 
+each pixel whose orinal value in the grey scale was over 127).
+
+Finally, each binary image was scaled again into a 16x16 square box (the 
+final 256 binary attributes).
