something i felt was missing from the piece - what is the typical hamming distance cutoff for something like this? he explains 2 is small enough to be identical but presumably it can go really high. what happens with a distance of like 100? what's the state of research on false positives and adversarial attacks?
- starkd 4y agoIt's tricky. You have to customize it. But any index method needs a fairly low threshold or the search devolves to a linear search. But as you increase the threshold, you quickly reach a cutoff where it's all just completely dissimilar images. So, a threshold of 100 would be utterly pointless.
