DreamBooth APK 为Android免费下载

It is an implementation of Google's DreamBooth Apk with stable distribution. The original App concept was based on a text-to-image model. However, models or pre-trend weights are not available from Imagine.

To allow people to modify the text-to-image model with some examples, I implemented it static propagation concept. This code repository is based on text inversion. Note that the exchange only adjusts the audio blur, while DreamBooth adjusts the entire diffusion model.

The implementation makes minimal changes to the official text reversal codebase. Due to laziness, some text-reversal components, such as embedded managers, are not removed, even though they are never used here.

About DreamBooth Apk

DreamBooth Apk is a teaching technique that uses a special form of fine-tuning to spark new ideas. Some people use it to put themselves in a good position with some of their photos, while others use it to add new styles. Diffuser provides a Dreambooth training script. Training does not take much time, but choosing the right hyperparameters is difficult and over-tuning can easily occur.

We conducted several experiments to analyze the effect of different DreamBooth Apk settings. This post presents our findings and some tips to improve your results when editing static spreads with the App.

Before starting, please note that this method should never be used for malicious purposes, to cause harm in any way, or to impersonate other people without their knowledge. Models trained with it are still bound by the CreativeML Open Rails-M license, which governs the distribution of static propagation models.

Recommended settings

The DreamBooth Apk fits very quickly. To get high-quality images, we need to find a good space between the number of training steps and the learning rate. We recommend using slow learning and gradually increasing the number of steps until the results are satisfactory.

The face requires more training steps. In our tests, 800-1200 steps worked well using a stack size of 2 and an LR of 1e-6. Pre-protection is important to avoid over-adjustment during facial training. In other respects, there is not much difference.

If you notice that the generated images have noise or the quality deteriorates, it means over-tuning. Try the above measures first to avoid this. If the generated images still have noise, use the DDIM scheduler or take other approximate steps (about 100 worked well in our tests).

Training non-unit text encoders have a significant impact on quality. Our best results came from a combination of text encoding, low LR, and appropriate metrics. However, text encoders require more memory to optimize, so a GPU with at least 24GB of RAM is ideal. It is possible to train on a 16GB GPU from Google Collab or Kaggle using techniques like 8-bit Adam, fp16 training, or gradient clustering.

Abstract

The large text-to-image model has made significant progress in the development of AI, allowing the high-quality and diverse synthesis of images from a given text prompt. However, these models cannot reproduce the occurrence of subjects in a given context sentence and to synthesize new representations in different contexts. In this work,

we present a new approach to “personalize” text-to-image diffusion models (features to user needs). Using only a few images of a subject as input, we modify a pre-trained text-to-image model (ImageGen, although our approach is not limited to a specific model) to recognize a particular subject. learn and generate a unique identifier.

Furthermore, once the object is entered into the model's output domain, the unique identifier can be used to synthesize an entirely new photorealistic image of the object for reference in different scenarios. Using the semantics already embedded in the model,

including new automatic class-specific pre-storage loss, our technique synthesizes the subject unseen in reference images of different scenes, poses, views, and lighting conditions. allows. We apply our techniques to a range of previously unspecified tasks, including subject subtitling, text-guided visual synthesis, appearance modification, and artistic rendering (preserving salient features of the subject).

Background

Considering a specific subject such as a clock (shown in the original images on the left), it is very easy to reproduce it in different contexts using advanced text-to-image models while maintaining high fidelity. is difficult Key visual features.

Even while repeating dozens of textual prompts describing the appearance of the clock (“a retro-style yellow alarm clock with a white dial and a yellow number three on the right side of the dial”),

the imagination model [Sahario et al. 2022] showed that the main visual feature (third column) could not be reconstructed. In addition, even models whose text embeddings are included in the general language concept space and can distinguish meaning from images,

such as DALL-E2 [Ramesh et al., 2022], because the subject has its appearance. cannot be rearranged or replaced. Reference (second column). In contrast, our approach can synthesize the (right) clock with high precision and new contexts (“[v]ild clock”).

Approach

Our method inputs a subject (e.g. a specific dog) and a corresponding category name (e.g. "dog") (3-5 images are sufficiently based on our tests), and a fine-tuning / "unique" text-to-image model that encodes a unique identifier associated with the subject. Next, we use several unique identifiers in the sentence as guesses.

For about 3-5 subject images, we refine the text-to-image diffusion in two steps: (a) fine-tune a low-resolution text-to-image model with the image text input, which is a unique identifier; provides, and class names that are subjects (such as "[t]o dog pictures"),

in parallel we apply a class-specific pre-protection vulnerability that exploits the semantics before entering the model. A text prompt classifies the classes and prompts for the creation of various examples (such as "pictures of dogs") associated with a subject class,

including the class name. (b) Refinement of super-resolution components with some low-resolution and high-resolution images taken from our input image set, allowing us to maintain high fidelity for small subject details.
