Some landmark papers in Machine Learning.

There are many papers that one could list but..

I very much enjoyed the following paper : "Machine Learning that Matters" that you can find in the following link (https://arxiv.org/abs/1206.4656) .

Also the paper in : "A few useful things to know about machine learning" downloadable here (http://dl.acm.org/citation.cfm?id=2347755) .
