    "Lucenalog = Datalog interface to Lucene in 10 lines.

Simple but powerful.

Use

  (db/add (index) {:a \"foo\" :b \"bar\"})

to index a map with Lucene.  Then you can use the relation

Notes on representing and computing uncertainty

Approach

A simple approach that uses sampling from either probability distributions or approximations of distributions as input and output from deterministic functions.

Terminology

As examples, we'll consider observations and predictions. A prediction is computed from a set of observations. We'll work with observations and predictions of probability distributions of tuples .
