An Introduction to Model Licenses in Deep Learning
Pay attention to this before deploying your next deep-learning project
Deep learning has witnessed explosive growth in recent years, with models capable of performing remarkable feats like image recognition, natural language understanding, and even generating content. These models are often built on extensive data and require significant computational resources. Nowadays, using such pre-trained deep learning models and fine-tuning them for your use case is common. However, their licenses are essential to consider when working with these models.
In this blog post, we will discuss the concept of model licenses in deep learning. We’ll explore why they matter, the different types of licenses available, and how you can use simple strategies to check model licenses well in advance to avoid any mishaps in your next project.
Why Do Model Licenses Matter?
Deep learning models are not just algorithms; they can be seen as intellectual property. Like any other form of intellectual property, the creators have the right to determine how their models can be used, shared, and modified. Model licenses are the legal mechanisms that define these terms. Here are a few reasons why model licenses matter:
- Legal Compliance: Using a deep learning model while violating its license terms can lead to legal issues.
- Ethical Considerations: Respecting model licenses is essential for fostering openness and collaboration in the deep learning community. Any violations can result in a reduction of trust and harm the reputation of the overall community.
- R&D Resources and Costs: Model licenses can impact research and development efforts. Some licenses may restrict your ability to use a model in certain applications, hindering your work and losing valuable resources.
Types of Model Licenses
Now that we understand why model licenses are important let’s take a look at some of the different licenses you may encounter in the deep learning landscape. Note that this is a very small subset of software licenses out there. For official documentation, check out this page.
- Open Source Licenses:
- MIT License: One of the most permissive open-source licenses. It allows you to use, modify, and distribute the model with minimal restrictions.
- Apache License 2.0: Similar to the MIT License, this license permits you to use, modify, and distribute the model, however, it includes some patent-related clauses.
- GNU General Public License (GPL): This license requires open-source derivative work. It places more restrictions on usage and distribution than the MIT and Apache licenses.
Creative Commons Licenses: For the complete list of Creative Commons Licenses check the link here. All CC BY licenses require proper attribution to the original author.
- CC BY (Attribution): With this license, you can use, modify, and distribute the model.
- CC BY-SA (Attribution-ShareAlike): This license requires attribution but also mandates that any derivative work must be licensed under the same terms.
- CC BY-NC (Attribution-NonCommercial): This restricts the use of the work for commercial purposes, requiring that any use must not be primarily intended for or directed towards commercial advantage or financial gain.
2. Proprietary Licenses: These restrictive licenses may require you to pay for the use of the model, limit your usage to specific applications, or prevent you from modifying the model.
3. Custom Licenses: Some creators/owners may choose to define their custom licenses, which can vary widely in terms and conditions. It’s imperative to review these licenses to understand their implications carefully.
How do you check model licenses?
Proprietary model owners usually do not open-source the code and provide access via an interface or an API. In the case of open-source models, you can find them hosted on Github as a repository. Within the repository, there is usually a file named LICENSE that you should be looking out for. Nowadays, Github has a cool feature where you can see an overview of the model license right after opening the License file. Unfortunately, this only works for license files that follow a certain format. If you cannot see this preview, you can check the license terms manually by referring to the section above.
The license details can also exist as a disclaimer notice at the bottom.
Final Thoughts
And that’s it! Licenses are pivotal in defining how to use, share, and build upon existing models. Before using any deep learning model, take the time to review its license carefully. This simple step can help you avoid legal issues and contribute to the continued growth and innovation in this field!
