Hi, In collaborative filtering algorithm , How can I define the number of features in the lecture there are only two features (Romance & Action movies) , what about if I make a large movie recommender system like Netflix , you know there are more than two types of movies , so How can I handle it?, and Thanks in advance
Hello, @Ashraf_25,
You must be talking about this silde:
As shown, two features corresponds to two values in the weight vector. In other words, if you want N features, you set the weight vector to have N values.
If you watch this lecture again, you will find that, after this slide, all subsequent discussions do not specify the lengths of the weights w and features x, which means that any length is fine, including N.
In the assignment, you will practice a case that is more than 2.
Cheers,
Raymond
