Study Notes

Emerging Trends in AI

Advancements in AI are focusing on generative models, particularly generative adversarial networks (GANs) and diffusion-based models.

Generative Adversarial Networks (GANs)

GANs involve two neural networks: a generator and a discriminator.
The generator creates synthetic data.
The discriminator assesses the authenticity of the generated data.
They compete in a zero-sum game, where one network's success is the other's loss.
The generator aims to create outputs indistinguishable from real data, while the discriminator is trained to recognize synthetic data.
This process improves the quality of generated outputs in continuous feedback loops.
GANs can generate high-quality images of human faces, but these faces might not be real.
GANs can also modify images or translate between different styles (e.g., day to night).
GANs come in different varieties, such as vanilla GANs, conditional GANs, deep convolutional GANs, CycleGAN, StyleGAN, and Super-resolution GANs, each with different applications.

Diffusion Models

Diffusion models are generative models trained to create data similar to the source data.
The models work by steadily adding Gaussian noise to the data and then training to remove the noise.
After training, models can create new data by applying this denoising process to random noise.
Advantages of diffusion models include high image quality, stable training, privacy-preserving data generation, and handling of missing data.
Application examples include text-to-image creation, image-to-image transformations, image search, and reverse image search.
The text-to-image process involves an encoder and a decoder.
The encoder converts textual descriptions into a numerical representation.
The decoder generates an image based on this numerical representation.
Intermediate steps involve creating progressively larger images through successive diffusion steps.
