📣💫 The 5th episode of #AIUnplugged is available on our YouTube channel !

The series explores how #AI is already being used across industries globally – in business, research, humanitarian action, government, and planning.

🔎🛡This week, we’re diving into AI and #cybersecurity with @KathrinGrosse , research scientist at @IBMResearch Zurich. Her work focuses on bridging the gap between AI #SecurityResearch and the real-world problems that AI users face every day.

Studies show that RL sharpens learned skills and can enable real generalization, but only with the right setup: 🏆
strong verification, dense rewards, structured training, and challenging data.

[EPFL Computer and Communication Sciences @ICepfl]

AI can solve Olympiad math… 🧮 
but still fails simple reasoning tasks 🤯

Today’s IC Colloquium by Nouha Dziri explores why and how we can build models that think more reliably 🤓.

[EPFL Computer and Communication Sciences @ICepfl]

And in this, what role does RL play? 👩‍🎓
In a world where models have seen almost everything, measuring real generalization is hard, so she tested reasoning across 3 levels:
→ applying a learned algorithm
→ combining multiple learned ones
→ inventing entirely new solutions
