This Lora uses an experimental guided training to ease the formation of the neural network.

Instructions are given through the images themselves. For this training run, a color association method is used.

The images in the training set are divided into two identical side-by-side images. On one side, the components of the female genitalia are colored distinctly.

In the image captions, the image is described as having two identical sides. Then, a description of the anatomical component to learn is given as well as the color of its colored region.

This isn't a general use Lora. The data set lacks a reasonable quantity of far and medium distances crotch. While there are some male pictures with color associated male genitalia, it's only a handful.

This training method is very efficient for complex concepts, such as the female genitalia as seen here, or hands, etc.

V2 expands the dataset. It shouldn't be very proficient at male genitals, but it's better. It should be better at farther distances, too.
