For Science Magazine, I wrote about "The Metaphors of Artificial Intelligence".

The way you conceptualize AI systems affects how you interact with them, do science on them, and create policy and apply laws to them.

Hope you will check it out!

Anthropic dropped some insights into how AI brains work with their circuit tracing method. Turns out LLMs are bad at math because they’re eyeballing it (“36+59? Eh, 40ish+60ish=95?”). It means we’re one step closer to understanding the inner workings of LLMs.

I am extremely honoured to receive the @ERC_Research
#ERCCoG award for #RUNES. For the next five years, I will be working on the mathematical, computational, and experimental (!!) sides to understand how higher-order interactions change how we think and coordinate.

A poster with a light blue background, featuring the paper with title: “A True-to-the-Model Axiomatic Benchmark for Graph-based Explainers”. Authors: Corrado Monti, Paolo Bajardi, Francesco Bonchi, André Panisson, Alan Perotti Background Explainability in GNNs is crucial for enhancing trust understanding in machine learning models. Current benchmarks focus on data, ignoring the model’s actual decision logic, leading to gaps in understanding. Furthermore, existing methods often lack standardized benchmarks to measure their reliability and effectiveness. Motivation Reliable, standardised benchmarks are needed to ensure explainers reflect the internal logic of graph-based models, aiding in fairness, accountability, and regulatory compliance. Research Question If a model M is using a protected feature f , for instance using the gender of a user to classify whether their ads should gain more visibility, is a given explainer E able to detect it? Core Idea An explainer should detect if a model relies on specific features for node classification. Implements a “true-to-the-model” rather than “truth-to-the-data” logic. Key Components White-Box Classifiers: Local, Neighborhood, and Two-Hop Models with hardcoded logic for feature importance. Axioms: an explainer must assign higher scores to truly important features. Findings: Explainer Performance Deconvolution: Perfect fidelity but limited to GNNs. GraphLIME: Fails with non-local correlations and high sparsity. LRP/Integrated Gradients: Struggle with zero-valued features. GNNExplainer: Sensitive to sparsity and edge masking. Real-World Insights: Facebook Dataset Fidelity in detecting protected feature use in classification. Results for different explainers, highlighting strengths and limitations. Contributions: Proposed a rigorous framework for benchmarking explainers Demonstrated practical biases and flaws in popular explainers

🌟🤖📝 **Boosting human competences with interpretable and explainable artificial intelligence**

How can AI *boost* human decision-making instead of replacing it? We talk about this in our new paper.

doi.org/10.1037/dec0...

#AI #XAI #InterpretableAI #IAI #boosting #competences
🧵👇
Article information Title: Boosting human competences with interpretable and explainable artificial intelligence. Full citation: Herzog, S. M., & Franklin, M. (2024). Boosting human competences with interpretable and explainable artificial intelligence. Decision, 11(4), 493–510. https://doi.org/10.1037/dec0000250 Abstract: Artificial intelligence (AI) is becoming integral to many areas of life, yet many—if not most—AI systems are opaque black boxes. This lack of transparency is a major source of concern, especially in high-stakes settings (e.g., medicine or criminal justice). The field of explainable AI (XAI) addresses this issue by explaining the decisions of opaque AI systems. However, such post hoc explanations are troubling because they cannot be faithful to what the original model computes—otherwise, there would be no need to use that black box model. A promising alternative is simple, inherently interpretable models (e.g., simple decision trees), which can match the performance of opaque AI systems. Because interpretable models represent—by design—faithful explanations of themselves, they empower informed decisions about whether to trust them. We connect research on XAI and inherently interpretable AI with that on behavioral science and boosts for competences. This perspective suggests that both interpretable AI and XAI could boost people’s competences to critically evaluate AI systems and their ability to make accurate judgments (e.g., medical diagnoses) in the absence of any AI support. Furthermore, we propose how to empirically assess whether and how AI support fosters such competences. Our theoretical analysis suggests that interpretable AI models are particularly promising and—because of XAI’s drawbacks—preferable. Finally, we argue that explaining large language models (LLMs) faces similar challenges as XAI for supervised machine learning and that the gist of our conjectures also holds for LLMs.

Even as an interpretable ML researcher, I wasn't sure what to make of Mechanistic Interpretability, which seemed to come out of nowhere not too long ago.

But then I found the paper "Mechanistic?" by
@nsaphra.bsky.social and @sarah-nlp.bsky.social, which clarified things.
Screenshot of the paper.

Since LLMs are essentially artefacts of human knowledge, we can use them as a lens to study human biases and behaviour patterns. Exploring their learned representations could unlock new insights. Got ideas or want to collaborate on this? Let’s connect!

In "Do I Know This Entity?", Sparse autoencoders reveal how LLMs recognize entities they ‘know’—and how this self-knowledge impacts hallucinations. These insights could help steer models to refuse or hallucinate less. Fascinating work on interpretability of LLMs!

In Scaling and Evaluating Sparse Autoencoders, they extract 16M concepts (latents) from GPT-4 (guess the authors?).
They simplify tuning with k-sparse autoencoders and results show many improvements in explainability. Code, models (not all!) and visualizer included.

ICLR is a top AI conference, and while the 2025 papers aren’t officially out yet, reviews are open. I’m diving into the highest rated in Interpretability and Explainable AI. Interestingly, the top ones focus on Mechanistic Interpretability, a promising topic that our team is starting to explore.

Bluesky feels like traveling back to the golden age of Twitter: when the follow button meant something, and your feed wasn’t a dystopian lineup of blue-tagged bots. It’s refreshing to be somewhere I don’t need an AI to explain why I’m seeing a post. Let’s hope we don’t ruin it this time!
