How Naive Bayes Classifiers Work – with Python Code …
Notice we have the Name of each passenger. We won't use that feature for our classifier because it is not significant for our problem. We'll also get rid of the Fare feature because it is continuous and our features need to be discrete. There are Naive Bayes Classifiers that support continuous features. For example, the Gaussian Naive …
The use of a Reflux Classifier for iron ores: Assessment of …
This work examined the potential for applying a vastly simpler approach, a single stage of gravity separation using the Reflux Classifier. Here the classified feed, 90 % finer than 0.150 mm, is sent directly to the Reflux Classifier, leading immediately to a high-grade concentrate at high solids concentration.

Antacids: what are they and how do they work?
This is called acid reflux, which can cause heartburn and/or inflammation of the gullet (oesophagitis). Antacids work by counteracting (neutralising) the acid in your stomach. They do this because the chemicals in antacids are bases (alkalis) which are the opposite of acids. A reaction between an acid and base is called neutralisation.
