Regrading Policy for hw0
- Only for obvious mistake of the grader such
as miscounting lost points.
- Only when you have explicitly stated the answers
correctly but still lost point >= 0.5. (Please DO NOT argue "implied
- Please don't come for point loss less than
- Only when your code produces correct answers
to all the input.
- Only when your files are unaltered to show
the original date of last modification before due time.
- No argument such as "my document is excellent".
(There has been no single documentation good enough; disappointing)
- No argument against the grading standard given
Grading Standard for hw0
Grey matter consists of neuron bodies at the outer surface of the brain
(not limited to cerebral cortex, at the base of the hemispheres,
and in the spinal cord).
Deep nuclei such as basal ganglia inside cerebral cortex
and other deep nuclei in cerebellum are somas buried inside the brain,
and are NOT grey because they are insulated.
2.1 no less than 0
depolarization due to Na+ channel opening(- .2),
repolarization due to Ka+ channel opening(- .2),
hyperpolarization due to Ka+ channel lengthy opening(- .2)
Magnetic moments are everywhere in the brain. Neural activities
deoxygenate hemoglobins to increase magnetic moment. THIS change
of gradient is detected by the fMRI machine. More fresh blood
inhences the opportunity of this deoxygenation to cause bigger change of magnetic
moment. More fresh blood itself is not a direct cause.
weighted sum (- .2)
discrete time (-.2)
firing at reaching the threshold or step function or all-or-none (-.2)
weighted sum - weighted single input < threshold <= weighted sum
For no submission, no compilation, and no running, please do not touch
your files and show the date to TA.
You may receive maximum 3 points back if he checks yours working. Contact
input file is given. If you do not know why you lost points,
please run it with your code. You may look at the input and
manually figure out what the answer should be.
(Do not alter the original so that the date is preserved just in case you
need to show it to TA.)
1) mimnum 1 for any compiling and running implementation (with excellent
documentation: minimum 2)
2) almost work : mimimum 3 with poor doc, maximum 5 with good doc
3) semi work : minimum 2 with poor doc, maximum 4 with good doc
4) runs but does not work : minimum 1 with poor doc, maximum 3 with good
5) doesn't compile or doesn't run : maximum 1 with good doc
a) doesn't compile in aludra (-6)
b) no Makefile or no input file (-1)
c) doesn't behave correctly (-2.4 = 6x.4 with good doc. ; -5 with bad
d) implement in simpler but comparable scheme (-1)
e) implement in simpler and brute-force scheme (-4)
f) doesn't run (-6)
