DMX Pitfalls : Natural Prediction Joins

Some very interesting, although time-consuming project kept me away from posting in the last month. Mea maxima culpa, I will try to catch up and put some new and interesting content here more often.

Recently, trying to make sense of some prediction results, I realized that the DMX NATURAL PREDICTION JOIN statement has some obvious and some not so obvious dangers, which deserve some clarification.

To summarize, the PREDICTION JOIN operator is used to apply patterns from a trained mining model against new data.
