Naive Bayesian Classifier in APL
This is a simple naive bayesian classifier to gain independent probabilistic assumptions on test input. The classifier requires precisely 2 groups with training data. This is just a fun side project I did over the weekend, but any contributions would be fantastic.
There are three files in this repository — each file works on its own:
- bayes.min.apl - This is the completely minified version.
- bayes.apl - This file isn't as obfuscated as the minified version, but it still follows conventional minified APL practices.
- bayes.full.apl - Fully documented
This example shows the classifier displaying the independent probabilistic assumptions on whether given text aligns with keywords of two different animals: cat or dog.
$ ("meow purr hiss bad animal" 0) ("bark grr howl good animal" 1) b "I am an animal and I hiss" 0.9999999995 4.999999994999999e¯10
The provided training data is the keywords and groups, with cat being the 0th index and dog being the 1st index. The test data consists of a string that contains keywords to align with a certain training group; in this example, cat is the classified group.
