2/16 When assignment 4 asks for VaR percentage, you should use the number 10 and _not_ the number .1.

2/14 10:10AM hw4 is now up.

2/11 This page has some interesting neural networks and finance papers.

2/11 Due to several people requesting extensions, solutions will not be posted for a couple of days. HW4 will be posted tomorrow.

2/1 Note on hw3: in matlab in windows, when you add a new data file, matlab won't find it until you re-execute the add to path command

2/1 More bugs from the assignment (I'm really sorry about these).

question 4: instead of (temperature = hot and humidity = low), it should be (temperature = hot and humidity = normal)

question 6: instead of:
[tree,p_t,test_acc,train_acc,pruned_test_acc,pruned_train_acc] = id3('credit.dat',50,0,50,r_seed).

it should be: [tree,p_t,train_acc,test_acc,pruned_train_acc,pruned_test_acc] = id3('credit.dat',50,50,0,r_seed).

question 7: instead of:
[tree,p_t,test_acc,train_acc,pruned_test_acc,pruned_train_acc] = id3('credit.dat',50,0,50,r_seed).

it should be :
[tree,p_t,train_acc,test_acc,pruned_train_acc,pruned_test_acc] = id3('credit.dat',50,25,25,r_seed)).

1/31 There is a bug in the assignment. If you've already printed it out, in part 2, question 4, you should erase the clause (temperature = high and humidity = overcast).

1/30 Assignment 3 is up.

1/28 I promised to post some pointers to matlab tutorials. Here they are:

Try the 'matlab basics' section of this for a good introduction.

There's a whole bunch of stuff at Indiana U.'s matlab reference page as well.

Also, there is a pretty good 36 page primer on matlab in
