🚆 Train But Verify: Securing Machine Learning Models

In today's digital era, artificial intelligence (AI) has become an integral part of various domains, revolutionizing the way we interact and make decisions. However, the deployment of AI systems is not without its challenges. Research suggests that a significant percentage of AI deployments fail due to the lack of a defined and repeatable system. This is where Train But Verify (TBV) steps in. TBV is an essential concept in AI engineering, a field that encompasses software engineering, systems engineering, computer science, and human-centered design. This article will delve into the world of TBV and explore its significance in securing machine learning models.

1️⃣ Introduction to AI Engineering

AI engineering is a multidisciplinary field that aims to build AI systems that are responsive to human needs and mission outcomes. It integrates various areas of expertise, such as software engineering, systems engineering, computer science, and human-centered design. The goal is to develop robust and secure AI systems that can effectively address real-world problems.

2️⃣ The Need for AI Engineering

The need for AI engineering arises from the fact that a significant number of AI deployments fail. The reason for these failures lies in the absence of a defined and repeatable system to achieve goals and mitigate risks. Research suggests that approximately 85% of AI deployments are unsuccessful. This highlights the importance of having a dedicated field of AI engineering to ensure the success of these deployments.

3️⃣ Understanding Threats to Machine Learning Models

To understand the significance of TBV, it is crucial to recognize the threats posed to machine learning models. These threats can be classified into three categories: learning the wrong thing, doing the wrong thing, and revealing the wrong thing. Each threat presents unique challenges in ensuring the accuracy, integrity, and security of machine learning models.

3.1 Learning the Wrong Thing

One of the threats to machine learning models is the potential to learn the wrong thing. Label poisoning, for example, can lead to models being trained on incorrect or malicious data, affecting their performance and reliability.

3.2 Doing the Wrong Thing

Another threat is models doing the wrong thing. Adversarial attacks can manipulate models into making incorrect decisions by presenting them with specially crafted inputs. This poses a significant risk, especially in high-stakes scenarios where accurate decision-making is crucial.

3.3 Revealing the Wrong Thing

The third threat involves models inadvertently revealing sensitive information about the training data. Adversarial attacks can extract Hidden Patterns or characteristics of the training data, compromising data privacy and security.

4️⃣ Overview of Train But Verify

Train But Verify (TBV) is a project that aims to address the threats discussed above. TBV takes a broad approach to ensure the security and accuracy of machine learning models. It consists of two main components: training to enforce a learn policy and verifying that the models adhere to the policy.

5️⃣ Challenges in Train But Verify

Implementing TBV comes with its own set of challenges. The main challenge is finding a balance between enforcing policies to ensure the models learn the right thing and avoiding unintended information leakage. The conventional methods used to enforce policies may inadvertently reveal critical information about the training data, compromising its security.

6️⃣ The Train But Verify Project

The Train But Verify project focuses on developing new methods and techniques to address the challenges posed by TBV. The project aims to quantify attacks, develop robust defense mechanisms, and create verification methods to ensure models are secure and accurate. By pushing the boundaries of AI engineering, TBV strives to provide organizations with high-stakes systems the tools to make informed decisions and protect sensitive data.

7️⃣ Global Robust Neural Networks

One of the key areas of research within the TBV project is the development of globally robust neural networks. These networks aim to ensure both local and global robustness, whereby small perturbations in the input data do not affect the model's output. By quantifying and minimizing the Lipschitz constant, which measures smoothness, these networks offer improved performance and resilience against adversarial attacks.

8️⃣ The Concept of Local and Global Robustness

To understand globally robust neural networks, it is important to grasp the concept of local and global robustness. Local robustness refers to the ability of a model to remain unaffected by small perturbations in the input data within a local region. Global robustness, on the other HAND, expands this concept to ensure that the model's output remains consistent across all possible variations of the input, within reasonable boundaries.

9️⃣ Introducing Globally Robust Neural Networks

Globally robust neural networks take the concept of local robustness further by ensuring that the model's predictions remain unchanged within a specified range of perturbations. By training the model to lower the score of the "bottom class," which represents the worst-case adversarial perturbation, globally robust neural networks achieve a higher level of resilience and accuracy.

🔟 Performance and Scalability of Globally Robust Neural Networks

The performance and scalability of globally robust neural networks set them apart from other models. Not only do they surpass or match the previous state-of-the-art on benchmark datasets, but they also demonstrate improved time and memory efficiency. These networks provide a solid foundation for building larger, more complex models such as those used for image classification in real-world scenarios.

1️⃣1️⃣ Juneberry: A Framework for Reproducible Machine Learning Research

To facilitate reproducible machine learning research, the TBV project has released a comprehensive framework called Juneberry. Juneberry offers a set of tools and adapters that enable researchers to conduct experiments in a controlled and replicable manner. Its extensibility allows for the incorporation of various machine learning tasks and back-end frameworks, such as PyTorch, TensorFlow, and more.

1️⃣2️⃣ Conclusion and Future Developments

The Train But Verify project is dedicated to addressing the challenges of securing machine learning models. By focusing on enforcing the right behavior and preventing the leakage of sensitive information, TBV aims to ensure the efficacy and integrity of AI systems. With ongoing research and the development of new training methods, TBV strives to provide organizations with the necessary tools to make informed decisions in high-stakes environments.
