Evaluating a machine learning model. - Jeremy Jordan

Jul 21, 2017 · To evaluate the model while still building and tuning the model, we create a third subset of the data known as the validation set. A typical train/test/validation split would be to use 60% of the data for training, 20% of the data for validation, and 20% of the data for testing. I'll also note that it's very important to shuffle the data before ...

May 16, 2017 · As you can see, if I choose parameters b and c to be 0, a to be 1, and d to be -0.0002930832 (which is -1/3412), I end up pretty close to my required result. And the good news is that parameters a , b, c and d can be learned from an algorithm. The result: machine learning! You might notice that the results are not exactly 1 or 0 because linear regression is a continuous model (trying to ...

How Underground Mining Works | HowStuffWorks

Underground mines are the alternative to surface mines. Surface mines excavate from the top down, a method that can become inefficient at depths greater than about 200 feet (60 meters) [sources: Illinois Coal Association, De Beers].Undergrounds coal mines can drive 2,500 feet (750 meters) into the Earth and other types even deeper -- uranium mines can reach 6,500 feet, or 2 kilometers.
