Lightroom Classic desperately needs the Sensei version of face recognition
Is there any chance we are ever going to get face detect in Lightroom Classic that comes anywhere close to working like it does in Lightroom CC? I was excited when face detection was first introduced because I could really benefit from it, but I almost immediately gave up on it because while the actual detection of faces is great, it is terrible at finding similar faces. Imagine my surprise today when I starting playing around with the same feature in the CC version at it is amazing. With no training on my part it had correctly identified dozens of individual people. It was 100% correct when it though photos were of the same person across very dissimilar photos. All I had to do was give each person a name.
Now lets compare that to a couple samples from Lightroom Classic. All of these photos are its guesses for a match to a 7 year old white girl. She already has 1500 photos confirmed as her so I can't see this getting any better over time.
I mean, seriously, how is this even trying? A see at least 4 different ethnicities, a 60 year age range, a dog, and a chain link fence. For the record none of these are the girl in question.
I am never going to use Lightroom CC as my primary photo editor. I can't afford the $1300/year it would take to store my entire photo collection in the cloud at the current costs and as a professional photographer I am not going to trust the primary copy of my photos to a server that I don't have control of. That being said, Adobe is putting some amazing technology in Lightroom CC and I would love to be able to take advantage of it. As it is, I can't even cycle photos through the cloud since non of the keyword syncing goes back to my Lightroom Classic catalog.

A plugin like Cloud tagger brings images to the cloud, doing the AI there and brings back the keywords to the desktop, why should Adobe could not?
I think, it's a delibarate choice, not technical limitations.

An idea on LR Classic, create a collection, synchronize it with LR Web, dynamic previews so created, do not on LR recognition Sansai, why, Adobe programmers could not find a solution for just complete a metadata fields so the content would be simply reduced to LR Classic, they do well for changes in development for fields 'Title' and 'Legend'! It's certainly ill will or simply does not listen to its own customers!

I don't know how the face recognition in LR Classic compares to LR CC, but this comparison isn't going to shed much light on it, unfortunately:
- Since face recognition was first introduced, the underlying recognition engine was replaced in LR 7.3. It's never been completely clear how LR handled the upgrade from the old engine to the new, and in particular, how well it incorporated the data from previously recognized faces into the indexing of new faces. I think it's very possible, perhaps likely, that if you made a copy of your catalog and discarded all existing confirmed faces and reindexed the faces, recognition across your photos would be significantly different.
- You're comparing the initial recognition in CC of the first dozens of instances of a person with your Classic catalog in which you've already confirmed 1500 photos, which isn't apples-to-apples. The machine-learning algorithms for face recognition produce an estimate of the probability that faces match. The recognizers in LR Classic and CC order matches presented to the user by that probability, the most likely matches first. So in your CC test, in which you've done little tagging, you're seeing the most likely matches for the girl being presented first, while in your Classic catalog, you've already tagged 1500 instances of the girl, so you're necessarily seeing possible matches that have much lower probabilities (that is, they're much less likely to be actual matches).
A more accurate comparison of CC with Classic would use the same exact corpus of photos in a fresh library / catalog.

There are three components to recognition algorithms: Identifying the bounding rectangles around the faces, extracting "features" from an individual face, and comparing those extracted features with the features of already tagged sets of faces in the catalog / library. None of these inherently get any benefit from running in the cloud.
If anyone has links providing authoritative information about the face recognition in CC and Classic, I'd love to learn more -- it's entirely possible I'm wrong. While I'm not an expert in face recognition, I have over 15 years of experience applying machine learning in various consumer-product domains, in startups and huge companies.

It wil only find similar faces, you have to name them yourself
