I do hope that the students are getting some numerical methods banged into
their heads, otherwise how can they accurately asses the errors in their
AI algorithms?

Which brings me back to fixed point. Once you show someone the simplicity
and elegance of simple, small, fixed point numbers, they may be able to
do the complex AI algorithms on embedded machines.

If they don't learn fixed point, they may see a simple 8-bit fixed point
processor and say it can't do AI because it has no FP numbers....

Just my 2cents, any other views out there on engineering education?

Depends exactly what you're teaching in the class, and how much time you
have. Spending a session teaching fixed point math may well mean that you
have to miss out a useful AI tool. If the students already understand how
to call, say "add(a,b)" then I don't see the relevance *in an AI course*
of teaching them the difference between doing "add()" in floating and
fixed point math.

Probably in a wider computing context they _ought_ to learn about fixed
point math one day, but I would suppose it belongs in a more general
course.

Anyway, that's my 0.02 GBP.
