   Can you explain more about why it's important to know non-frequent items at any given point in time? This will in general return a bunch of noise that would be filtered out using even the less-aggressive NO_FALSE_NEGATIVES flag. It does not provide a way to distinguish actual frequent items from a few items that happened to be added once but have low enough counts as to be meaningless.
