Generative Adversarial Interpolative Autoencoder (GAIA) is a Generative Adversarial Network (GAN) made up of Autoencoders (AE) trained explicitly on interpolations to promote convexity and better latent interpolations.

The Generative Adversarial Interpolative Autoencoder (GAIA; Paper; Blog post) is novel hybrid between the Generative Adversarial Network (GAN) and the Autoencoder (AE). The purpose of GAIA is to address three issues which exist in GANs and AEs:

1. GANs are not bidirectional
2. Autoencoders produce blurry images
3. Autoencoder latent spaces are not convex

Instructions

1. Download the GAIA dataset with the notebook 'Create_CELEBA-HQ.ipynb'
2. Download the trained weights 'download_weights.ipynb'
3. Run the notebook 'GAIA simple example.ipynb'

Note: I'm currently in the process of rewriting this code to be cleaner, include more features, etc. For now, this is just the version of the code used in the Arxiv paper.
