sum of percentage #205

Open grotef opened 4 years ago

grotef commented 4 years ago

If I have only learned one position, I always have a 100% probability, even if I am somewhere else. Is it possible to get below 100%, for example by choosing the algorithms?

Even if I have learned several positions, the sum of the probabilities is always 100%. It should also be possible that the sum of probabilities is much less than 100 or not? So if I am outside of the learned positions the percentage of the learned positions should decrease strongly.

I think the probability is how match the rssi of a device compared to learnt data. Nothing to do with the sum of percentage.

As you learn too near locations, then the probability may be reduced.
