# Algorithms

This page describes a feature of Haut.AI SaaS Platform that allows you to perform AI analysis of image data.

{% hint style="warning" %}
Algorithms feature is available for <mark style="color:green;">**all**</mark> plans, but some Algorithms are included only in <mark style="color:purple;">**Professional**</mark> plan
{% endhint %}

{% hint style="info" %}
Algorithms section is available as [App Marketplace section in SaaS](https://saas.haut.ai/app/applications)
{% endhint %}

## About Algorithms

Algorithms is an AI core functionality of Haut.AI products. Algorithms enable AI image analysis. Algorithms can be used:

* in [Consumer Apps](/haut.ai/haut.ai-features/consumer-apps.md) (for Avanced+ plan)
* via API (for Professional plan)

Algorithms are organized into **Applications** that combine one or more algorithms.

There are several Applications available for usage in <mark style="color:green;">all</mark> plans:

* Face Skin Analysis 3.0 Application
* Face Metrics 2.0 Application: check more here: [Face Metrics 2.0](/haut.ai/haut.ai-features/algorithms/face-metrics-2-0.md)
* Recommendation Engine Application: check more here: [Recommendation System (legacy)](/haut.ai/haut.ai-features/algorithms/recommendation-system-legacy.md)
* Hair Metrics 2.0 Application
* Beautification Application

There are several Applications available for usage only in the <mark style="color:purple;">Professional</mark> plan:

* Acne Pro Application
* Pigmentation Pro Application

## Getting Started with Algorithms

To be calculated, Algorithms require a Dataset with images to be created first.

{% hint style="info" %}
To create a new Dataset, follow the guide [Datasets](/haut.ai/haut.ai-features/datasets.md#getting-started-with-datasets)
{% endhint %}

1. Navigate to the [App Marketplace section in SaaS](https://saas.haut.ai/app/applications).
2. Open an Algorithms Application by clicking on the **name of the application.**
3. Click the “Attach application” button.
4. Choose an existing Dataset in the drop-down menu "Choose dataset to run this application."
5. Click "Start."

Now the selected Algorithms Application is attached to the Dataset and all the images, that will be uploaded to this Dataset afterwards will be processed with all the Algorithms in this Application.

{% hint style="danger" %}
Algorithm Applications do not have retrospective data processing!

This means that all images uploaded to the Dataset BEFORE attaching the Algorithm Application **will not be processed with this Application**.
{% endhint %}

## FAQ

### What is the cultural diversity profile of the algorithms in the Skin SaaS platform?

Our algorithms are agnostic to phenotype and skin tone. We use diverse and balanced datasets and best practices in diverse AI to train our models.

### How were the algorithms validated?

Our algorithms are validated against clinical evaluation criteria. The quality analysis of the algorithms and the data annotation are implemented by data scientists, dermatologists, biologists, and skin experts. The algorithms are not certified as medical devices, but the methods were described in publications in peer-reviewed journals. Check out the Haut.AI articles [here](https://scholar.google.com/citations?user=ItBfAp0AAAAJ\&hl=en\&oi=ao).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.saas.haut.ai/haut.ai/haut.ai-features/algorithms.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
