The methodology used to run implementations of DreamBooth involves the fine-tuning the full UNet component of the diffusion model using a few images (usually 3--5) depicting a specific subject. Images are paired with text prompts that contain the name of the class the subject belongs to, plus a unique identifier.
The model is insufficiently trained to understand human limbs and faces due to the lack of representative features in the database, and prompting the model to generate images of such type can confound the model. [37] Stable Diffusion XL (SDXL) version 1.0, released in July 2023, introduced native 1024x1024 resolution and improved generation for ...
DALL-E 2 is a 3.5-billion cascaded diffusion model that generates images from text by "inverting the CLIP image encoder", the technique which they termed "unCLIP". The unCLIP method contains 4 models: a CLIP image encoder, a CLIP text encoder, an image decoder, and a "prior" model (which can be a diffusion model, or an autoregressive model).
"The UAE is one of the biggest outside actors fueling the violence in Sudan, and yet the U.S. is on the brink of selling the UAE another $1.2 billion in weapons that could end up in the hands of ...
The Fréchet inception distance (FID) is a metric used to assess the quality of images created by a generative model, like a generative adversarial network (GAN) [1] or a diffusion model. [ 2 ] [ 3 ] The FID compares the distribution of generated images with the distribution of a set of real images (a "ground truth" set).
Former national security adviser H.R. McMaster argued that the ongoing conflict in Gaza will continue and life for Palestinians cannot improve “until Hamas is destroyed.” McMaster joined ...
Tech billionaire Elon Musk labeled a section of President-elect Trump supporters as “contemptible fools” as the online debate around visas for highly skilled workers on the right intensifies.
In 2021, the release of DALL-E, a transformer-based pixel generative model, followed by Midjourney and Stable Diffusion marked the emergence of practical high-quality artificial intelligence art from natural language prompts. In 2022, the public release of ChatGPT popularized the use of generative AI for general-purpose text-based tasks. [42]
