Re: What is the best way to store and look-up a "similarity vector"?by BrowserUk (Pope)

But is that how a project like Panopticlick calculates "similarity" across bit-vectors?
I've no idea about pana-pano, that thing, but ostensibly, it can be as simple as counting the number of matching bits (properties):
For parts/product catalogue type applications, bit-mapped data records can be very effective and efficient, because their attributes tend to have a fixed (and limited) number of values. Ie. Half a dozen colors; half a dozen sizes; 2 or 3 finishes; etc. That means each choice can be represented by a bit position in a vector. Selection can be extremely fast.
