UnverifiedT2-Z adds a learnable environment latent on top of a standard world model, used to condition world predictions, and requires no supervision signal about environment factors.75% similarUnverifiedT2-Z's training process alternates between the world model optimization phase and the environment latent optimization phase.72% similarUnverifiedT2-Z belongs to the test-time adaptation (TTA) paradigm, avoiding full-model fine-tuning for each new environment and compressing adaptation capability into a low-dimensional latent variable.68% similarUnverifiedUnder the T2-Z framework, the environment latent variable is currently inferred once through initial interaction when entering a new environment, and then remains fixed.66% similarVerifiedA world model refers to a robot's internal predictive capability of the physical environment—given the current state and an action, it can predict what will happen next.59% similar
