Face recognition - any tips for re-finding?

Ignore the post, I've reported it as spam

Rob, thanks for having a go at the question - neither version was what I was after! I'll try to explain again as evidently I wasn't clear enough.

The screen-shot is interesting as I hadn't come accross that at all and wouldn't have looked at that aspect either.

Let's try again.

I've a folder, not "all photos" but let's call it "Our Family". Lots of sub-folders by year and so on. 

At the start I selected my folders at the Our Family level and told it to detect faces. This is unfortunately a huge job because there are lots of images to crunch and many of them include other people - for example if you take a shot of your family at a tourist spot there are other tourists with faces, which LR locates and then suggests for you to name. There are also weddings and Christenings where, whilst I know some of the folk, I don't know others (and may not care to name them if I do know them because I'm looking at my own family).

As one goes through naming individual faces the "top half" (the "named people" section) starts to populate with the names that one has identified. The "bottom half" (the "un-named people" section) variously fills up with names of people for some and questionmark for others. Note that it fills up... and that's part of the magic... and what I'm trying to get to.

Let's say we've got three people: Mark, Matt, Martin. They are relatives and get confused by the system as it tries to identify them. The "bottom half" of  the view, with suggested names and question marks, has a list of names which are quite probably wrong. Martin gets identified as Matt, Matt gets identified as Martin, Mark gets identified as both Matt and Martin, and so on. That's fair enough. I go through and start to correct that "initial identification".

As this is all AI learning of what people look like one presumes that it learns as it goes along. And yet the grid of names never seems to change. It filled up initially and then it... stopped changing.

In my case I've found that photos of my son get identified as me or as my father. I get identified as my father or my son (depending on the age of the person in the photo). Indeed I also get identified as either of my siblings.

Personally I can look at a photo of my sister as a toddler and know it is her and not me, and vice versa. Not so certainly as a baby - then I go for context of who else is in the photo and where it was taken and what does the image look like in terms of film visual.

As I go through correcting discrepencies like that I can imagine that LR gets better at its job of "initial identification". As such if I were to choose a new folder and tell it to identify people I might hope that it gives a better "initial identification" of the people involved and the "unnamed people" section might more closely identify those in the images.

However I've already done a scan of the "Our Family" folder to ask it to identify people and guess at their names. It took a while, and as I said, it detected faces that I don't care to identify and would discard.

What I'm therefore wondering is if there is some way to tell Lightroom itself to look again at the remaining "unnamed people" section and for it to have another guess at those based on what it now knows about the people that I have already identified. Can it match Mark/Matt/Martin any better than it did the first time through?

I don't want to re-scan the lot, just the ones I've not identified yet to see if its suggestions improve.

From what I've seen there is no option for that. However, as I'm new to this area of the tool I figured it's worth asking as it would save me a lot of time - particularly when it gets to the baby photos that exist for most of my family in there.

Does that make my question any more clear?
