PROC.OF THE IEEE,NOVEMBER 1998 was collected among Census Bureau employees,while SD-1 was collected among high-school students.Drawing sensi- > 68/79b641 ble conclusions from learning experiments requires that the b 757863485 result be independent of the choice of training set and test among the complete set of samples.Therefore it was nec- 2【79 7 a 86 essary to build a new database by mixing NISTss datasets. SD-1 contains 5s,517 digit images written by 5yy dif- 4819018894 ferent writers.In contrast to SD-3,where blocks of data 子61&6 4/5b0 from each writer appeared in sequence,the data in SD-1 is scrambled.N riter identities for SD-1 are available and we 7592658197 used this information to unscramble the writers.N e then split sD-1 in twoe characters written by the first 5y writers 2久22234480 went into our new training set.The remaining 5y writers 038073857 were placed in our test set.Thus we had two sets with nearly 3y,yyy examples each.The new training set was 01446024a completed with enough examples from SD-3,starting at pattern c y,to make a full set of Py,yyy training patterns. 7/281o98b Similarly,the new test set was completed with SD-3 exam- ples starting at pattern c 35,yyy to make a full set with Aig..Size-normalized examples from the MNIST database.
