The similarity measure is the measure of how much alike two data objects are. Sets: A set is (unordered) collection of objects {a,b,c}. The following line of code will create a new column in the data frame that contains a number between 0 and 1, which is the Jaccard similarity index. The DataFrame movie_cross_table containing all the movies as rows and the genres as Boolean columns that you created in the last lesson has been loaded. The Jaccard similarity index measures the similarity between two sets of data. To measure the similarity between these two sets, you can use the Jaccard Similarity, which is given by the intersection of the sets divided by their union. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example.
