Summary · TLDR

This is part 1 in a series of articles on model mapping, a novel approach developed at Martian to understand the inner workings of neural networks. Model mapping was first introduced in our previous article, and in this piece, we will discuss its role in AI alignment.

‍

In the rapidly evolving landscape of artificial intelligence, the challenge of AI alignment looms large. As our models grow more powerful and complex, the need to ensure that they remain aligned with human values and goals becomes increasingly pressing. But how can we hope to align systems that we struggle to understand?

‍

Enter model mapping, a groundbreaking approach that promises to revolutionize the way we interpret and align AI systems. By leveraging the power of category theory, model mapping enables us to transform the opaque neural networks of today into the transparent, verifiable programs of tomorrow. And at Martian, we're at the forefront of this exciting new frontier.

Turning Transformers into Programs

Converting neural networks to programs.

At the heart of model mapping lies a simple yet profound idea: if we can convert neural networks into programs, we can analyze and verify them using the well-established tools of software engineering. It's a bit like taking a complex machine and creating a blueprint that shows how all the parts fit together.

The key to this process is a mathematical framework called category theory. In essence, category theory allows us to study objects not by looking inside them, but by examining their relationships to other objects. And when we apply this lens to neural networks, something remarkable happens.

By focusing on the relationships between different models, rather than their internal structures, category theory enables us to create mappings that preserve the essential features and behaviors of the original networks. These structure-preserving mappings, known as functors, are the magic ingredient in model mapping.

Validating the Effectiveness of Model Mapping

Our research demonstrates the effectiveness of model mapping through the training of functors that convert transformers into programs. These functors achieve high accuracy in both sparse-to-program and dense-to-program mapping tasks, showcasing the ability of model mapping to extract faithful algorithmic representations from neural networks.

The validation of functoriality as a measure of faithfulness further strengthens the case for using model mapping as a tool for measuring alignment. By establishing a strong correlation between functoriality and accuracy, we show that functoriality can serve as a reliable proxy for assessing the faithfulness of the extracted algorithms, and by extension, the alignment of the original models.

Scalability and Generalizability

One of the most promising aspects of model mapping is its potential to scale. Traditional approaches to mechanistic interpretability, which involve meticulously analyzing the internal workings of neural networks, are too time-consuming and resource-intensive to keep pace with the rapid evolution of AI.

Model mapping, on the other hand, offers a scalable alternative. With the extracted programs in hand, researchers and developers can employ well-established techniques from software engineering and formal verification to assess the correctness, safety, and alignment of the original models.

By automating the process of extracting programs from neural networks, it opens up the possibility of analyzing and aligning AI systems at an unprecedented scale. Our initial experiments have yielded promising results.

We've successfully trained functors that can map transformers of varying sizes into programs with high accuracy. Crucially, we've demonstrated that the functoriality of these mappings strongly correlates with their faithfulness to the original models. This is a promising breakthrough as it provides us with a reliable, quantifiable method to assess the alignment of AI systems.

Beyond Alignment: The Multifaceted Promise of Model Mapping

While AI alignment is a central focus of model mapping, its benefits extend far beyond this critical challenge.

Consider, for instance, the challenge of model efficiency. As AI models become increasingly large and complex, the computational resources required to train and run them are becoming prohibitively expensive. By mapping models into more compact or efficient representations, we can mitigate this burden without compromising performance.

Or take the issue of model adaptation. In many real-world applications, AI systems need to be able to quickly adapt to new tasks or environments. Model mapping can facilitate this by enabling us to transfer knowledge between models or to modularize them into reusable components.

And then there's the realm of human-AI interaction. By mapping models into formats that are more intuitive and accessible to non-experts, such as natural language or visual representations, we can democratize AI and make it easier for people from all walks of life to engage with and benefit from these powerful tools.

Join Us on the Journey

At Martian, we're actively building on this approach. But we know that realizing the full potential of model mapping will require a collaborative effort spanning academia, industry, and beyond.

That's why we're committed to sharing our work and engaging with the broader AI community. In the coming months, we'll be releasing a range of tools and techniques based on model mapping, and we invite researchers, developers, and enthusiasts from all backgrounds to join us in exploring this exciting new frontier.

Whether you're developing state-of-the-art models, deploying AI systems in real-world applications, or simply seeking to stay at the cutting edge of this rapidly evolving field, we believe that model mapping has something to offer.
