See log for assignment and due dates.
HW1 1.1, 1.2, 1.3, 1.4, 1.5 [J01], 2.1 [J96].
24 pts--4 points per part.
HW2 1.6, 1.7, 1.8, 1.9, 1.10.
25 pts--5 points per exercise.
HW3 (Hugin=PR1) Exercise 1.11, 1.12, 1.13, 1.14, 1.15.
20 points in all. (1.11) 2 point
if the student reports
installation of Hugin (any version) on his or her PC; or, if the student
announces his or her intention of using the version in the lab; or, if the
student has done the other exercises, because this indicates that the student
can use Hugin.
(1.12) 3 points for a net file.
One point off with the wrong DAG.
Commendation for a screen dump.
Additional commendation
for two screen dumps or a screen dump showing two nets.
Additional commendation for screen dumps
indicating that evidence was entered.
(1.13, 1.14: 5 points each)
Check that three nets are
submitted. Check the structure. If wrong, take out up to three points per
exercise.
HW4 (Hugin=PR2) 30 points in total
Ex. 2.1: 5 points. Check structure. If wrong, take off 3 points.
Ex.2.2: 3 points. Check structure. If wrong, take off two points.
Ex. 2.3: 3 points. If wrong answer, take off two points.
Ex. 2.4: 4 points. If wrong answer, take off two or three points.
Ex. 2.6, 6 points. 3 for part (i), 3 for part (ii). Check especially that the
numbers computed in part(i) are used in part (ii).
Ex. 2.7, 1 point.
Ex.2,8: (i) 2 points
The probability of infected milk is the same for each one of the
days, with the probabilities in the book. In particular, P(Inf_{i+1}=yes |
Inf_i = no) = 0.0002. Some students incorrectly used 0.0005 instead,
and they noticed instability: P(Inf1) = 0.07, and P(Inf7) = 0.13.
Take 1 point
off for this.
(ii) 3 points. Full credit for "logical" argument; full credit for algebraic
proof.
(iii) 3 points. Full credit for "logical" argument; full credit for algebraic
proof.
PR3 10 points
Ex. 2.9 1 point
Ex. 2.12 9 points
