AlignSAE: Concept-Aligned Sparse Autoencoders

arXiv — cs.LGTuesday, December 2, 2025 at 5:00:00 AM
  • The introduction of AlignSAE, a method designed to align Sparse Autoencoder features with a defined ontology, marks a significant advancement in the interpretability of Large Language Models (LLMs). This approach employs a two-phase training process, combining unsupervised pre-training with supervised post-training to enhance the alignment of features with human-defined concepts.
  • This development is crucial as it addresses the challenge of entangled feature representations in LLMs, allowing for a clearer understanding and control of specific relations within the model's latent space. By creating dedicated slots for concepts, AlignSAE enhances the usability of LLMs in various applications.
  • The emergence of AlignSAE reflects ongoing efforts to improve the interpretability and reliability of LLMs, a topic of increasing importance in AI research. As LLMs continue to evolve, the need for methods that ensure accurate representation of knowledge and mitigate risks associated with misalignment becomes paramount, particularly in fields requiring high levels of precision, such as biomedical applications.

Measuring What LLMs Think They Do: SHAP Faithfulness and Deployability on Financial Tabular Classification
NeutralArtificial Intelligence
A recent study evaluated the performance of Large Language Models (LLMs) in financial tabular classification tasks, revealing discrepancies between LLMs' self-explanations of feature impact and their SHAP values. The research indicates that while LLMs offer a flexible alternative to traditional models like LightGBM, their reliability in high-stakes financial applications remains uncertain.
SECA: Semantically Equivalent and Coherent Attacks for Eliciting LLM Hallucinations
NeutralArtificial Intelligence
A recent study introduced Semantically Equivalent and Coherent Attacks (SECA) aimed at eliciting hallucinations in Large Language Models (LLMs) through realistic prompt modifications that maintain semantic coherence. This approach addresses the limitations of previous adversarial attacks that often resulted in unrealistic prompts, thereby enhancing the understanding of how LLMs can produce hallucinations in practical applications.
