AI image generation is a subfield of machine learning that involves training a model to learn patterns in existing images and then generating new images based on those patterns. There are several AI image generation techniques, but two of the most popular are Generative Adversarial Networks (GANs) and Variational Autoencoders (VAEs).
GANs consist of two neural networks: a generator and a discriminator. The generator generates images that are intended to fool the discriminator into thinking they are real. The discriminator, on the other hand, tries to distinguish between real and generated images. Through repeated training, the generator becomes better at generating images that are increasingly difficult for the discriminator to distinguish from real images.
VAEs, on the other hand, work by encoding an image into a low-dimensional space and then decoding it back into an image. The goal is to make the encoded image as close as possible to the original image, while also ensuring that the encoded image can be easily manipulated to generate new images.
Pixiv has embraced AI image generation, providing a platform for artists to showcase their AI-generated artwork. Some of the most popular AI-generated art on Pixiv includes anime-style portraits, landscapes, and abstract art. AI-generated anime-style portraits are particularly popular, with artists using GANs and VAEs to generate images that look like they could be characters in an anime.
One of the benefits of AI image generation is that it allows artists to experiment with new styles and techniques. For example, an artist who is used to drawing in a traditional style can use AI to generate a new style that is different from their usual style. This can be a great way to expand an artist's creative range and explore new possibilities.
However, there are also concerns about the impact of AI on the art world. Some argue that AI-generated art lacks the soul and emotion of art created by humans. Others worry that AI-generated art could lead to a devaluation of human creativity and skill as well as using the works of others.
