It should be clear now that, for our association rule mining algorithm, we need to provide the minimum support and confidence threshold values. Are there are any set guidelines? No, it all depends on the dataset. It would be worthwhile to run a quick experiment to check how many rules are generated for different values of support and confidence. This experiment should give us an idea of what our minimum support/confidence threshold value should be, for the given dataset.
Here is the code for the same:
