SALVE: Enabling Mechanistic Control and Interpretability for Enterprise AI
Deep neural networks, while powerful, often act as black boxes. SALVE (Sparse Autoencoder-Latent Vector Editing) introduces a groundbreaking "discover, validate, and control" framework that bridges mechanistic interpretability with precise, permanent model editing. This allows for fine-grained control over AI behavior, enhancing transparency and reliability crucial for high-stakes enterprise applications.

Understanding Model Decisions: Bridging Interpretation and Control
SALVE offers a unified 'discover, validate, and control' framework that seamlessly connects mechanistic interpretability with direct model editing. It addresses the critical challenge of deep neural network opacity by reverse-engineering internal computations. By identifying internal structures that correspond to meaningful concepts and establishing their influence on outputs, SALVE enables enterprises to gain unprecedented transparency into their AI systems. This foundational understanding is then leveraged for precise, permanent interventions, ensuring AI systems are not only performant but also comprehensible and trustworthy.
Precision Engineering: Permanent Weight-Space Interventions
Unlike temporary, inference-time steering methods, SALVE performs permanent, continuous weight-space interventions. This allows for fine-grained modulation of both class-defining and cross-class features by directly editing the model's weights. The method supports suppressing or enhancing specific features, leading to predictable changes in model behavior with minimal off-target effects. This is critical for applications requiring fixed, verifiable model states and ensuring consistent behavior across all uses of the edited model. The approach's robustness has been validated across diverse architectures like ResNet-18 and Vision Transformers.
Unsupervised Feature Learning: Sparse Autoencoders
At the heart of SALVE is the unsupervised discovery of model-native features using an l₁-regularized sparse autoencoder (SAE). This process learns a sparse, interpretable feature basis directly from the model's internal activations. To validate the semantic content, we employ Activation Maximization, synthesizing abstract visual concepts that a feature represents. Additionally, our novel Grad-FAM (Gradient-weighted Feature Activation Mapping) visually grounds these latent features in specific input regions, providing a direct link between abstract concepts and their manifestation in data. This ensures the discovered features are semantically meaningful and reliable for targeted interventions.

Targeted Control: Resolving Ambiguity with Feature Editing
In a qualitative case study, SALVE was applied to an ambiguous, out-of-distribution image containing both a 'golf ball' and a 'church'. The original model predicted 'Church', with Grad-CAM focusing on the church tower. SALVE demonstrated its precision by first suppressing the dominant 'Church' feature, which predictably flipped the classification to 'Golf ball'. Conversely, enhancing the 'Golf ball' feature achieved the same outcome. Post-edit Grad-CAMs confirmed the model's attention shifted accordingly. This example highlights SALVE's ability to exert precise, modular control over model predictions by directly manipulating its learned concepts, even in complex or ambiguous scenarios.
