I wish to use Java to program, hope that doesn't matter. Would that be alright? : ) Also, although I've been working on this project for a while, the dataset still confuses me. And as the DDL drawing near, I chose to use another dataset that can make it easier for me to understand the problem. I chose to use this datasets: accidents, mushroom, T10I4D100K as it has been issued and approved. Is that ok?

The data sets: accidents, mushroom, T10I4D100K.

RT. THX!

1. The Task.1 and the Task.2 seem to share a common title in the slides. Is it an accident? If so, what's the original description of Task.2? Analyze the correlation of different attributes of the data given and show it in a table or graph?

2. The Task.3 asks us to finish a phrase mining task based on the frequent pattern. Here, "phrase" seems to be ambiguous. For example, if a word A is always followed by a adjacent word B, then we call "A B" as a phrase. However, if A always appears with B but they are not adjacent, like "A ***** B", then, should "A B" also be a phrase?
   I am not sure if I am clear.

Thank you.

i will illustrate usage and provide config method

I'd like to implement Fpgrowth algorithm. But I'm not sure how to test the algorithm's performance. Should I test the accuracy or something else? Thanks for response.
