Today, I’m thrilled to share a major milestone—
A dream sparked in a small town of farms and chalkboards 🌾📚
My first paper as an independent researcher was accepted to one of the world’s top AI & ML conferences.
Here’s how I got here. 👇 arxiv.org/pdf/2506.03404

🚨The Formalism-Implementation Gap in RL research🚨 Lots of progress in RL research over last 10 years, but too much performance-driven => overfitting to benchmarks (like the ALE). 1⃣ Let's advance science of RL 2⃣ Let's be explicit about how benchmarks map to formalism 1/X

Proud to have contributed, as an independent researcher, to the great work achieved by our research team. Many thanks to @johanobandoc , @lavoiems , Scott Fujimoto, @AaronCourville and @pcastr for making it happen. See Pablo’s thread for more details.

🔊Simplicial Embeddings (SEMs) Improve Sample Efficiency in Actor-Critic Agents🔊 In our recent preprint we demonstrate that the use of well-structured representations (SEMs) can dramatically improve sample efficiency in RL agents. 1/X

Huge thanks to all the amazing researchers who made this possible, and especially to @johanobandoc for his guidance and for welcoming me, as an independent researcher, into this and many other projects.
It’s been a truly enriching and fascinating journey

1/3 🥳Excited to share our new paper ‘Simplicial Embeddings Improve Sample Efficiency in Actor–Critic Agents’! Project your features onto a product of simplices → sparse, stable reps, stronger grads, faster learning. 🧵For more details, check out Pablo’s thread 👇

Scaling up networks in deep RL is tricky: do it naively, and performance collapses 😵‍💫 Why? Increasing depth and width leads to severe vanishing gradients, causing unstable learning ⚠️ We diagnose this issue across several algorithms: DQN, Rainbow, PQN, PPO, SAC, and DDPG.

 If you also come from a place where people say “it can’t be done”
 Here’s my message: 💥 Yes, it can.
 🌾 There’s science in our villages.
 🏙️ There’s talent in our neighborhoods.
 🚀 And there’s a future for those who dream big.
