These 5 libraries are great, each with its own merit; however, why do we care so much about open source AI libraries in the first place?
Importance of open source AI libraries
The free nature of open source technologies, coupled with the robust community support, makes open source appealing to most organizations. There are numerous benefits to using open-source AI solutions. Some of these are:
- Transparency
- Security
- Robust community support
- Ease of collaboration
Transparency
One of the numerous benefits of open source AI projects is transparency. All the code changes are public. This way, users can see the source code and understand how the software works end-to-end, how it processes data, and what dependencies it needs.
Security
Open source ML libraries allow for extensive code review, leading to more secure software being distributed. Bugs and vulnerabilities are often quickly identified and fixed by the community. This way, users pay close attention to security, adding vulnerability tests to the CI/CD workflows and automating the detection of threats in the libraries.
Robust community support
Open source AI tools usually have large, active communities. This way, when users encounter problems or have some issues regarding the software, they can easily create an issue on GitHub or ask a question on the community forum.
Ease of collaboration
A collaborative environment in open source AI projects builds rapid innovation by bringing together a diverse community of ML engineers, software engineers, technical writers, and users looking for a way to contribute to the library. The open nature allows anyone to contribute to bug fixing and feature implementation, creating an ecosystem of continuous integration and development.
Though open-source AI libraries offer numerous benefits, they can also present challenges that impact efficiency and the overall user experience.
Challenges with open source AI frameworks
While open source AI libraries offer a range of powerful tools, many fall short when addressing the challenges machine learning teams face when deploying models at scale in production. Some of these challenges are:
- High latency
- Version control
- Security
High latency
Latency refers to the time delay between a user's request and the response received from the server. Techniques such as quantization, pruning, and model distillation can be employed to address this issue. Additionally, production-optimized formats like open neural network exchange (ONNX), a platform-independent format for deep-learning models, can reduce latency and improve performance.
Version control
Version control is essential for collaboration in software development, with systems like Git, SVN, and Mercurial playing a crucial role. These tools facilitate collaboration, help track changes, and are indispensable for any development team.
However, versioning AI systems presents unique challenges due to the complex data structures and formats involved. Machine learning models are typically defined by their weights, hyperparameters, preprocessing steps, and architectures, all of which may need to be versioned separately or as a unified entity, adding layers of complexity.
Given the sensitivity of machine learning systems to the data they are trained on, it's vital to version data alongside models to ensure reproducibility and maintain an understanding of the model's performance over time.
Security
Security is another critical concern in AI workflows. This is due to the vast amounts of data used during training and inference, often including sensitive or personally identifiable information *****(PII).* Safeguarding this data is essential for maintaining the integrity of the workflow. Common security threats in AI production environments include:
- Model theft occurs when a user tries to gain unauthorized access to a model, which can involve gaining unauthorized access to a repository containing its models and configurations.
- Adversarial attacks are when users try to deceive the models into making incorrect or harmful predictions by modifying input data.
Having secure storage for your models, datasets, and code is beneficial in ensuring your artifacts are safe and secure.
You’ve learned about some of the challenges faced by open source libraries, let’s look at a few solutions.
