An Open Place To Speak Up

Dear Data Miners,

The blog should be fully utilized by us through posting of questions and doubts that we have since there's not much 'discussion' during lectures.

Anyone that has answers or can help clear those doubts and questions from others can also post their comments. So, let's help make this blog as informative as possible.

As the saying goes:
"NO MAN'/WOMAN' IS AN ISLAND"

Regards.
