There are certain limitations but our results add to the #verification vs. #validation debate in #gait #analysis. #Marker-based and #markerless systems may never yield perfectly matching #kinematics, but maybe they don't need to. We must understand their differences to use them where they work best.

📊 Key results:
• Comparable performance to #OpenCap
• Challenges in #ankle #kinematics
• Reliable kinematics (RMSD ≈ 3°)
• Reasonable accuracy (RMSD ≈ 5.5°)
→ promising for #remote & #home-based #gait #assessment
#Markerless 3D #motion #capture keeps moving forward and #monocular methods could make gait analysis even more accessible. In this study, we propose a low-cost monocular system, combining #CameraHMR & #OpenSim against both #OpenCap and a marker-based reference under various gait conditions.

This work is a step toward AI systems people can:
✔️ Understand
✔️ Trust
✔️ Use responsibly
Big thanks to my coauthors:
Roberto Labadie, Xihui Chen, Adrian Jaques Böck, Andreas Babic, Liz Freimann, Christiane Atzmüller & Matthias Zeppelzauer
📊 Results:
✅ #SCBM balance interpretability & performance
✅ They achieve (or surpass) state-of-the-art results
✅ Compete even with large #Transformers
✨ What’s inside?
🔹 Distilling knowledge from #LLMs into transparent #SCBM
🔹 Using domain-specific human-understandable adjectives as concepts
🔹 A novel class-discriminative loss for #interpretability
🔹 Applied to #hate & #counterspeech recognition
🧩The idea: Instead of predicting directly, #SCBM goes through a layer of human-understandable concepts. We leverage #LLMs to evaluate adjective-based concepts that capture the intention & tone on #socialmedia .
This way, the model explains why it decides.
In our new paper "Distilling knowledge from large language models: A #concept #bottleneck #model for #hate and #counterspeech recognition" we introduce Speech Concept Bottleneck Models #SCBM - a step toward #interpretable #LLM.
📄https://doi.org/10.1016/j.ipm.2025.104309
AI systems must be accurate but also #understandable. Trust in #AI depends on #transparency. Yet Large Language Models (#LLMs) remain #blackboxes.
How do we make them #interpretable without losing performance? 👇
