Each terrain, biome, and structure is generated through algorithms, ensuring that no two game experiences are identical, showcasing the power and variability of procedural generation in crafting visual content.
Generative Adversarial Networks (GANs)
Generative Adversarial Networks, introduced by Ian Goodfellow et al. in 2014, consist of two neural networks – a Generator and a Discriminator – that are trained simultaneously through adversarial training. The generator creates new data instances, while the discriminator evaluates them, with the generator improving its ability to create fake data, and the discriminator improving its ability to distinguish fake from real.
The Generator takes random noise as input and generates samples. The Discriminator then receives samples from both the training data and the generator, and has to identify whether the sample is real or generated. This process is akin to a forger trying to create a counterfeit painting, while an art detective tries to detect which one is fake. Over time, the forger becomes so skilled at creating paintings that the detective can’t tell real from fake.
Variants & Developments
Numerous variants and developments of GANs have emerged, such as CycleGANs for image-to-image translation, StyleGANs developed by NVIDIA for generating highly realistic images, and BigGANs for large-scale and high-fidelity image synthesis.
Example: StyleGAN2, developed by NVIDIA, has been used to generate hyper-realistic human faces that do not exist, exemplifying advancements in creating high-fidelity images.
Variational Autoencoders (VAEs)
Variational Autoencoders are a type of generative model that aim to learn the underlying probability distribution of the training data. They are composed of an encoder, a decoder, and a loss function, with the encoder capturing the data’s underlying distribution in a latent space, and the decoder generating new data points from this space.
Differences with GANs
While GANs are adept at generating high-quality and realistic images, VAEs are more structured in representing the latent space and are better suited for tasks that require understanding of the data distribution, such as anomaly detection, data denoising, and more.
VAEs have found applications in generating and modifying facial images, drug discovery by generating molecular structures, and generating music by understanding the underlying patterns and structures in the input data.
Example: SMILES (Simplified Molecular Input Line Entry System) representation of molecules has been used in conjunction with VAEs for drug discovery, showcasing their capability in generating structured and meaningful data.
Transformer models, introduced in the paper “Attention is All You Need” by Vaswani et al., have revolutionized Natural Language Processing and have also been adapted for image generation tasks. They rely on self-attention mechanisms and are capable of capturing long-range dependencies in data.
