Gonz,

In order to go from 2048D to 2D, there are a couple of techniques for
dimensionality reduction out there. I'm using the most common one. Look
here:

Re: And now for something different

It all sounds pretty straightforward, but I'm curious about the last
step of folding 2048D -> 2D.  Must involve some kind of clustering?
How is this done?  This seems key.

Okay, interesting, thanks for explaining!

I have been doing something remotely similar with face-recognition on multiple 
live video-streams a few years ago, for supermarket customer-following systems

Not at all, I am a programmer too, mainly making disk and filesystem recovery

> Just out of curiosity, what was the input to the Neural Network?

No, it's just the pixels themselves. I'm using a pretrained convolutional
neural network, or CNN. You know how Google Photos is able to separate
photos into categories, with dogs, food, mountains, etc? That is done with
a neural network of the same type.

These CNNs will output the confidence they have that an image belongs to
one of many classes they were trained for. But in the process they compute
a vector that sort of encodes what "features" exist in the image. Features
are things like lines, dots, patterns, and also combinations of things that
might form "higher level features", like eyes, bicycle wheels, etc etc.
These vectors are of very high dimension, in this case 2048.

It turns out that points in this 2048-D space will be close to each other
if the images they come from are similar to each other.

The process I'm using computes and saves this vector for each image. That
alone allows me to do image similarity search, by comparing these vectors.

In order to make the plot, I use a technique that "folds" those 2048
dimensions into two, so I can find a position for each image on the plane.
