### New Param Ranges

As it turns out, I had a flawed assumption about Bernouli NB. I thought that the binarize parameter was a percentage threshold, where instead it is a value threshold.

In other words, I was under the impression a binarize of 0.3 meant that the bottom 30% of values got translated to 'low' and 70% got translated as 'high'. This is not the case. A binarize of 0.3 means that all values below 0.3 become 'low' and all values greater than 0.3 become 'high'.

Below are the results generated from Bernouli NB without the binarize parameter being fixed. For the next set of results, I intend to pre-process the inputs by normalizing 0-100 and then providing a binarize param of 0-100.
