Excited to be at @RL_Conference 🇨🇦 this week! I'm presenting two talks on logical composition in RL (Aug 6, Track 3) + a poster at @RLFrameWorkshop on a simple yet effective approach for non-Markov RL (Aug 5). Huge thanks to my amazing co-authors 🥳. Come say hi!

Congratulations to our two new lab members for being awarded the Google PhD Fellowship! 🥳 We can't wait to see the exciting work that lies ahead.

@DeepIndaba Very grateful to @DeepIndaba for the awesome recognition!

🌟Celebrating African research excellence at #DLI2025! 🌟 The Kambule Doctoral Award recognises and encourages excellence in research and writing by doctoral candidates at African universities, in any area of computational and statistical sciences. This award celebrates African research excellence and honours Thamsanqa Kambule’s legacy as a defender of learning, seeker of knowledge, and activist for equality. 👏 Congratulations to Lexy Andati (Rhodes University & SARAO) and Geraud Nangue Tasse ( University of the Witwatersrand). #DLI2025 #Indaba2025 #Urunana

🚀 We’re excited to unveil the first lineup of technical tutorials and practicals at #DLI2025! These sessions go beyond training—they reflect our mission of building AI in Africa, “Urunana” (hand in hand). Attendees will gain hands-on experience, exploring advanced topics: Pracicals: ✨ Machine Learning Foundations ✨ Generative Models & LLMs for African languages Tutorials: ✨ Mathematics of Deep Learning ✨ Introduction to Deep Generative Models 📌 All tutorial content will also be available online after the Indaba. Don’t miss out—subscribe here 👉 lnkd.in/eCgXRqsV

@KaliTessera @RL_Conference @RLFrameWorkshop Yeah, long time! See you soon

@geraudnt @RL_Conference @RLFrameWorkshop Ah awesome, will be great to catch-up!

@tw_killian @raillabwits @RL_Conference @RLFrameWorkshop Same!

@geraudnt @raillabwits @RL_Conference @RLFrameWorkshop Looking forward to seeing you there!

@NileshArnaiya @RL_Conference @RLFrameWorkshop Crazy!

@geraudnt @RL_Conference @RLFrameWorkshop Just 3 days apart, or we could have met in Edmonton 🥹

Great news! This work has also been accepted into RLC for the Journal to Conference Track. Congrats @geraudnt and teams for the great result 🦾

Our paper, “Make Haste Slowly: A Theory of Emergent Structured Mixed Selectivity in Feature Learning ReLU Networks” will be presented at ICLR 2025 this week (openreview.net/forum?id=27SSn…)! We derive closed-form dynamics for some, remarkably linear, feature learning ReLU networks (1/9)

Many thanks to my supervisors Steven James & @BenjaminRosman to their extensive help in the long journey to this paper. If you're working on: multitask RL, interpretable RL, logical reasoning in RL, sample-efficiency and generalisation ... this might be of interest! (8/8)

This work builds on our Boolean Task Algebra NeurIPS paper, but takes it much further: E.g. Generalises: Task composition to any environment (even stochastic) and any reward function; Extended value functions to WVFs, supporting general deterministic goal-reaching tasks. (7/8)

Thrilled to share that our paper was just published in JAIR (jair.org/index.php/jair…)! We formalise task composition in RL using lattice structures📷, building a general framework for logical composition over arbitrary tasks beyond Boolean logic. (1/8) 🧵👇

I'm excited to announce that I have received the Thuthuka Research Grant from the @NRF_News! I will use this grant to start my own lab focused on comp neuro and ML theory at @WitsUniversity: the @caandl_lab! This is a joint effort with @VictoriaWi83762, @stefsmlab and @geraudnt.
