Assignment 3 o
In the use of the liblinear package you should use
the option that returns the probability of each class (-b in the case that
you use the command line interface). You should classify a tip to the class
with the highest probability if the probability is above the threshold θ. The recall value that you will compute is the
fraction of the tips that are classified, while the precision value is the
fraction of the classified tips that are classified correctly. You will
produce 9 (precision, recall) pairs and you will plot them with recall being
on the x axis, and precision on the y axis. ·

the for Assignment: o
For the second question, what you are asked to
produce is the set of (s,t) bipartite cliques, for input values of s and t.
The sentence about the “types” and the “interests” of users serves only as a
motivation as to why we would like to find such cliques. o
For the third question, if you want to use WEKA you
would need to find a way to load the data in a sparse form. This is not
obvious in WEKA, so you may want to use one of the implementations of FIMI
instead. ·
