The accuracy
How often each inference is right — because a wrong inference is experienced as being misunderstood.
The deliverable
What it is
An attribute inferred at seventy per cent accuracy is wrong for three people in ten. Whether that is acceptable depends entirely on what happens when it is wrong.
The cost of a wrong inference is asymmetric: a missed opportunity is invisible and a wrong assumption about someone is not.

Below the confidence threshold, show the default rather than a guess. A confident wrong guess is worse than neutral.

What each personalisation is based on — stated preference, observed behaviour or inferred attribute.
LearnThe correction
How a customer can fix a wrong inference — because a visible and correctable inference is tolerated and an invisible wrong one is not.
