Environment generation is the missing scaling axis for embodied AI. Introducing SimWorld Studio: a self-evolving factory for endless interactive 3D env where agents act, fail & learn. Env-agent co-evolvution improves navigation success 50% → 90%. From a prompt, our SimCoder

🧠Human brain has internal world model for conscious reasoning 🤖Language model reasoning also need world model! Reasoning via Planning (RAP) is a new principled framework for this. It prompts LM as WM & reasons w/ MC TreeSearch Better v ChainOfThought on plan-gen, math, logic

🤖LLMs (autoregressive transformers) are not designed to reason in non-linear structures like humans... 🤔Instead of using it as a straight-minded reasoner, what about regarding it as a world model🌎and planning with it? Check out our new work: Reasoning via Planning (RAP) 🧵

I was kidding -- this video was entirely simulated by the _world model_ we're building. 😀 It's mind-blowing how it produces high-fidelity simulations, lasting several minutes, to complete non-trivial tasks. This showcases the potential for infinite data & experience in

📣 Introducing LLM Reasoners (github.com/Ber666/llm-rea…), a library for advanced reasoning with LLMs. Simply define a reward function and an optional world model, and let LLM Reasoners take care of the rest, including Reasoning Algorithms, Visualization, LLM calling, etc.

Super excited to introduce Pandora, a generative video World Model interactively controllable by language. #Sora and #GPT4 are both powerful. How about fusing them in a single model? 💥 Pandora gives a preview:🔭 > Build a General World Model (GWM) super efficiently by

🤯Machine Learning has many paradigms: (un/self)supervised, reinforcement, adversarial, knowledge-driven, active, online learning, etc. Is there an underlying 'Standard Model' that unifies & generalizes this bewildering zoo? Our @TheHDSR paper presents an attempt toward it 1/

🗣️Language Models ➕ 🌎World Models When the two fascinating models start to interplay with each other, lots of exciting things happen! 🔥Here we use WM to teach LM diverse embodied knowledge and skills. Improve by 64% on 18 tasks, and let GPT-J-6B surpass chatGPT! 🔥

XLNet Pytorch for generation is now ready in Texar-pytorch! Play with XLNet & GPT-2 here. Figs show how XLNet and GPT-2 think of each other (w/ nucleus decoding) — It looks XLNet is looking forward GPT-3 which must be supervised :) github.com/asyml/texar-py…
