...
interesting, I was just load testing streaming on webpieces on records per second vs. requests per second. I think requests/second is in that same ballpark(100 to 200) but with streaming it shoots up to 1140 records / second (doing ndjson). Anyways tho...

A simple explanation of Naive Bayes Classification
...ght with a particular input dataset (training set) so that later on we may test them for unknown inputs (which they have never seen before) for which they may classify or predict etc (in case of supervised learning) based on their learning. This is what most of the Machine Learning techniques like N...
