Rethinking Sparse Autoencoders: Select-and-Project for Fairness and Control from Encoder Features Alone

arXiv — cs.LGMonday, December 8, 2025 at 5:00:00 AM
  • A new framework called S&P Top-K has been introduced to enhance the functionality of Sparse Autoencoders (SAEs) by allowing for model steering through encoder features alone. This method improves fairness metrics in vision-language models, particularly on datasets like CelebA and FairFace, by up to 3.2 times compared to traditional approaches.
  • This development is significant as it offers a retraining-free and computationally efficient way to control model behavior, potentially leading to more interpretable and fair AI systems. By focusing on encoder features, it shifts the paradigm of model steering in machine learning.
  • The introduction of S&P Top-K aligns with ongoing discussions in the AI community regarding the interpretability and fairness of machine learning models. As researchers explore various methods to enhance the performance and accountability of AI systems, the emphasis on encoder-centric approaches highlights a growing trend towards improving model transparency and ethical considerations in AI applications.

Discovering Influential Factors in Variational Autoencoders
NeutralArtificial Intelligence
A recent study has focused on the influential factors extracted by variational autoencoders (VAEs), highlighting the challenge of supervising learned representations without manual intervention. The research emphasizes the role of mutual information between inputs and learned factors as a key indicator for identifying influential factors, revealing that some factors may be non-influential and can be disregarded in data reconstruction.
A Geometric Unification of Concept Learning with Concept Cones
NeutralArtificial Intelligence
A new study presents a geometric unification of two interpretability paradigms in artificial intelligence: Concept Bottleneck Models (CBMs) and Sparse Autoencoders (SAEs). This research reveals that both methods learn concept cones in activation space, differing primarily in their selection processes. The study proposes a framework for evaluating SAEs against human-defined geometries provided by CBMs.
