Excellent, clear explanation by stripping it right down to the core!

One thing I noticed is that the in the initial “Probability density map for where I dropped my phone (based on my knowledge of where I dropped” grid the sum of probabilities equates to 1, but in the “Revised probability that my phone is in a certain square.” it does not (0.93)

Shouldn’t this not always sum up to 1?

– for clarity you could add explicitly P(Not found | Is not there) to Bayes formula and say that it is 1 (hard to find something if it isn’t there)
– also you could say that P(Not found | Is there) + P(Found | Is there) = 1
but for me the last formula is somewhat foggy. Could you give an example of computation here please?

Anyway, cool blog
