guidance) and diversity (low guidance).</p> <p><strong>Two CFG Formulations:</strong></p> <!> Moves conditional predictions further from unconditional ones. <!> Moves unconditional predictions toward conditional ones, effectively suppressing negative features (e.g., "bad

guidance. It proposes zero initialization of the noise predictions for the first few steps of the diffusion
process, and also introduces an optimal rescaling factor for the noise predictions, which can help in improving the
quality of generated images.</p> <p>The authors of the paper suggest setting zero initialization in the first 4% of the inference steps.</p></div> <!> <div class="docstring border-l-2 border-t-2 pl-4 pt-3.5 border-gray-100 rounded-tl-xl mb-6 mt-8"><!> <p>Skip Layer Guidance (SLG): <a href="https://github.com/Stability-AI/sd3.5" rel="nofollow">https://github.com/Stability-AI/sd3.5</a></p> <p>Spatio-Temporal Guidance (STG): <a href="https://huggingface.co/papers/2411.18664" rel="nofollow">https://huggingface.co/papers/2411.18664</a></p> <p>SLG was introduced by StabilityAI for improving structure and anotomy coherence in generated images. It works by
skipping the forward pass of specified transformer blocks during the denoising process on an additional conditional
batch of data, apart from the conditional and unconditional batches already used in CFG
([~guiders.classifier_free_guidance.ClassifierFreeGuidance]), and then scaling and shifting the CFG predictions
based on the difference between conditional without skipping and conditional with skipping predictions.</p> <p>The intution behind SLG can be thought of as moving the CFG predicted distribution estimates further away from
worse versions of the conditional distribution estimates (because skipping layers is equivalent to using a worse
version of the model for the conditional prediction).</p> <p>STG is an improvement and follow-up work combining ideas from SLG, PAG and similar techniques for improving
generation quality in video diffusion models.</p> <p>Additional reading:</p> <ul><li><a href="https://huggingface.co/papers/2406.02507" rel="nofollow">Guiding a Diffusion Model with a Bad Version of Itself</a></li></ul> <p>The values for <code>skip_layer_guidance_scale</code>, <code>skip_layer_guidance_start</code>, and <code>skip_layer_guidance_stop</code> are

future without warning or guarantee of reproducibility. This implementation assumes:</p> <ul><li>Generated images are square (height == width)</li> <li>The model does not combine different modalities together (e.g., text and image latent streams are not combined

worse versions of the conditional distribution estimates. PAG was one of the first techniques to introduce the idea
of using a worse version of the trained model for better guiding itself in the denoising process. It perturbs the
attention scores of the latent stream by replacing the score matrix with an identity matrix for selectively chosen
layers.</p> <p>Additional reading:</p> <ul><li><a href="https://huggingface.co/papers/2406.02507" rel="nofollow">Guiding a Diffusion Model with a Bad Version of Itself</a></li></ul> <p>PAG is implemented with similar implementation to SkipLayerGuidance due to overlap in the configuration parameters
