# Creating Custom Algorithms

FELT Labs currently offers one algorithm that can be used to train certain types of machine learning models or perform data analytics on CSV data. However, if you have a specific use case that requires a different algorithm, we offer two options.

First option, you can tell us what you need and we can create a custom algorithm for you. Once the algorithm is developed, you will be able to easily run it on your data. To request a custom algorithm, you can reach out to us on our Discord channel and provide us with the details of your use case.

Second option, you can build your own algorithm. This page provides information how to do that. We encourage you to let us know if you decide to build your own algorithm, so that we can assist you and ensure that the final product meets your needs.

Overall, our goal is to provide flexible options for using our platform and to ensure that specific data analysis and machine learning objectives could be achieved, whether that involves using our pre-existing algorithm or developing a custom solution.

## How to Build a Custom Algorithm

To create algorithms that are tailored to your specific use case, you will need to develop two separate algorithms: one for local training and another for aggregation. The local training algorithm runs on the data iteself, computing intermediate results. Those results are then aggregated with the aggregation algorithm.

We provide a simple example of what such a pair of algorithms looks like in our GitHub repository, which you can find here:

You can also check out the implementation of our existing algorithms here:

Once you have developed your algorithms, you will need to publish them as two separate algorithm assets on the Ocean Protocol. Instructions for doing so can be found at the following link:

After you have developed and published your algorithms, you can use them on our platform. In step 2 (choose algorithm) use "Use s custom algorithm" and fill the dids of your algorithms. In step 3 you will be able to provide any additional parameters in form of a JSON object (optional).

Do you want your algorithms to be listed? Let us know and we will review them. By listing your algorithms on our platform, you make it available to other users who may benefit from them. Plus when others are using your algorithms, you are receiving a passive income.

Our goal is to help you create algorithms that meet your specific needs and to foster collaboration and innovation in the data science community. If you have any questions don't hesitate to reach out to us.

# Agent Instructions: 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:

```
GET https://docs.feltlabs.ai/guides/creating-custom-algorithms.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
