The ability to create models for all areas that I'm interested in such as social media analysis or eCommerce/retail prediction it's like having your own little statistical wizard! It has been extremely difficult at times but mostly because not enough people know how to use this software effectively (I think). There are so many different ways you can train an algorithm using these features which makes learning much easier when compared with other tools out there. If used correctly then they have really helped me get where we needed too be - being able to achieve what others cannot do themselves and save time by doing more myself :).
