title: Classification not Regression
type: descriptive
text: In the standard example of digits recognition, why is it a Classification problem and not a Regression problem?
opt: NULL
ans:
- Since the output are actually digits and not numerical values and hence the digits are completely independent from digits which are closer to them.
q_img: NULL
sol:
For example; 1 and 7 look quite alike, if we used a regression model on an input which has an ambigious interpretation between 1 and 7, it would give a result of something like 3 or 4 which would be no where near the correct or most appropriate answer because it would average out the results from 1 and 7.
