I will try my best to simplify my question.
I'm using FieldAwareFactorizationMachine in ml.net.
I supplied 2 inputs values for training C1 and C 2 refer below table.
Basically i did predict probablilty of column 1 with column column 2 .
for ex. A form c1 and 1 from c2 has predicted value is around 0.8
A form c1 and 2 from c2 has predicted value is around 0.7
A form c1 and 3 from c2 has predicted value is around 0.6
but i want to predict value of A from c 1 with 1,2,3 from c 2 where total of 1 , 2 ,3 will be 1.0
i.e A with 1 = 0.50
A with 2 = 0.25
that is total of c2 column is 1.0
