Data Science - Part VII - Cluster Analysis 

Thank you Derek. I have been reading this stuff over and over for the past six weeks and thanks to PART VI and VII I am finally able to make sense of Association Rules and Clustering.

You have a good set of tutorials on Data Science. I wish there was no background noise in your videos. It makes concentrating and understanding so much difficult. Also I would have liked some R code when you get in the practical application section of your videos. Thanks anyways for your great videos.

Thanks always. I keep watching your videos to study data analysis.

Many Thanks Mr.Derek, it's useful lecture, wish if the sound was higher,....

Great video But it feels like your allergic to being heard,

Thank you for the excellent videos.

wish I could hear what you were saying, way too much background noise

Your voice is almost indiscernible due to background noise. :(

unfortunately you talk a bit too soft

Very bad voice clarity
