	<span>What is a scheduler?
	</span></h2>

<p>The schedule functions, denoted <em>Schedulers</em> in the library take in the output of a trained model, a sample which the diffusion process is iterating on, and a timestep to return a denoised sample.</p>
<ul><li>Schedulers define the methodology for iteratively adding noise to an image or for updating a sample based on model outputs.<ul><li>adding noise in different manners represent the algorithmic processes to train a diffusion model by adding noise to images.</li>
<li>for inference, the scheduler defines how to update a sample based on an output from a pretrained model.</li></ul></li>
<li>Schedulers are often defined by a <em>noise schedule</em> and an <em>update rule</em> to solve the differential equation solution.</li></ul>

	<span>Discrete versus continuous schedulers
	</span></h3>

<p>All schedulers take in a timestep to predict the updated version of the sample being diffused.
The timesteps dictate where in the diffusion process the step is, where data is generated by iterating forward in time and inference is executed by propagating backwards through timesteps.
Different algorithms use timesteps that both discrete (accepting <code>int</code> inputs), such as the <a href="/docs/diffusers/pr_2/en/api/schedulers#diffusers.DDPMScheduler">DDPMScheduler</a> or <a href="/docs/diffusers/pr_2/en/api/schedulers#diffusers.PNDMScheduler">PNDMScheduler</a>, and continuous (accepting <code>float</code> inputs), such as the score-based schedulers <a href="/docs/diffusers/pr_2/en/api/schedulers#diffusers.ScoreSdeVeScheduler">ScoreSdeVeScheduler</a> or <code>ScoreSdeVpScheduler</code>.</p>

	<span>Designing Re-usable schedulers
	</span></h2>

<p>The core design principle between the schedule functions is to be model, system, and framework independent.
This allows for rapid experimentation and cleaner abstractions in the code, where the model prediction is separated from the sample update.
To this end, the design of schedulers is such that:</p>
<ul><li>Schedulers can be used interchangeably between diffusion models in inference to find the preferred trade-off between speed and generation quality.</li>
<li>Schedulers are currently by default in PyTorch, but are designed to be framework independent (partial Jax support currently exists).</li></ul>

	<span>API
	</span></h2>

<p>The core API for any new scheduler must follow a limited structure.</p>
<ul><li>Schedulers should provide one or more <code>def step(...)</code> functions that should be called to update the generated sample iteratively.</li>
<li>Schedulers should provide a <code>set_timesteps(...)</code> method that configures the parameters of a schedule function for a specific inference task.</li>
<li>Schedulers should be framework-specific.</li></ul>
<p>The base class <a href="/docs/diffusers/pr_2/en/api/schedulers#diffusers.SchedulerMixin">SchedulerMixin</a> implements low level utilities used by multiple schedulers.</p>

<p>Denoising diffusion implicit models is a scheduler that extends the denoising procedure introduced in denoising
diffusion probabilistic models (DDPMs) with non-Markovian guidance.</p>
<p><a href="/docs/diffusers/pr_2/en/api/configuration#diffusers.ConfigMixin">~ConfigMixin</a> takes care of storing all config attributes that are passed in the scheduler’s <code>__init__</code>
function, such as <code>num_train_timesteps</code>. They can be accessed via <code>scheduler.config.num_train_timesteps</code>.
<a href="/docs/diffusers/pr_2/en/api/configuration#diffusers.ConfigMixin">~ConfigMixin</a> also provides general loading and saving functionality via the <a href="/docs/diffusers/pr_2/en/api/configuration#diffusers.ConfigMixin.save_config">save_config()</a> and

<p><a href="/docs/diffusers/pr_2/en/api/configuration#diffusers.ConfigMixin">~ConfigMixin</a> takes care of storing all config attributes that are passed in the scheduler’s <code>__init__</code>

<a href="/docs/diffusers/pr_2/en/api/configuration#diffusers.ConfigMixin">~ConfigMixin</a> also provides general loading and saving functionality via the <a href="/docs/diffusers/pr_2/en/api/configuration#diffusers.ConfigMixin.save_config">save_config()</a> and

<p>For more information, see the original paper: <a href="https://arxiv.org/abs/2011.13456" rel="nofollow">https://arxiv.org/abs/2011.13456</a></p>
<p><a href="/docs/diffusers/pr_2/en/api/configuration#diffusers.ConfigMixin">~ConfigMixin</a> takes care of storing all config attributes that are passed in the scheduler’s <code>__init__</code>
function, such as <code>num_train_timesteps</code>. They can be accessed via <code>scheduler.config.num_train_timesteps</code>.
<a href="/docs/diffusers/pr_2/en/api/configuration#diffusers.ConfigMixin">~ConfigMixin</a> also provides general loading and saving functionality via the <a href="/docs/diffusers/pr_2/en/api/configuration#diffusers.ConfigMixin.save_config">save_config()</a> and

<p>The variance preserving stochastic differential equation (SDE) scheduler.</p>
<p><a href="/docs/diffusers/pr_2/en/api/configuration#diffusers.ConfigMixin">~ConfigMixin</a> takes care of storing all config attributes that are passed in the scheduler’s <code>__init__</code>
function, such as <code>num_train_timesteps</code>. They can be accessed via <code>scheduler.config.num_train_timesteps</code>.
<a href="/docs/diffusers/pr_2/en/api/configuration#diffusers.ConfigMixin">~ConfigMixin</a> also provides general loading and saving functionality via the <a href="/docs/diffusers/pr_2/en/api/configuration#diffusers.ConfigMixin.save_config">save_config()</a> and
<a href="/docs/diffusers/pr_2/en/api/configuration#diffusers.ConfigMixin.from_config">from_config()</a> functions.</p>
