Beyond Myopic World Models: Long-Horizon End-to-End Training for Direct Future Prediction
Xinyi Li, Zaishuo Xia, Chenjie Hao +1
World models are expected to support imagination over extended temporal horizons, yet most are still trained through local few-step prediction objectives and deployed by recursivel…
Toward a mechanistic understanding of inference in visual cortex and diffusion models
Zeyu Yun, Alexander Belsten, Dasheng Bi +3
We describe a model of perceptual inference in primary visual cortex (V1) equivalent to a minimal diffusion model whose function can be readily understood from its parameters. The…
Concept-Guided Spatial Regularization for World Models in Atari Pong
Yukuan Lu, Zaishuo Xia, Weyl Lu +1
The paper evaluates several visual world‑model agents on Atari Pong, identifies systematic rollout failures, and introduces Concept‑Guided Spatial Regularization (CGSReg) to improv…
When Models Know When They Do Not Know: Calibration, Cascading, and Cleaning
Chenjie Hao, Weyl Lu, Yuko Ishiwaka +3
When a model knows when it does not know, many possibilities emerge. The first question is how to enable a model to recognize that it does not know. A promising approach is to use…
MotionPyramid: Hierarchical Motion Representation and Residual Interfaces
Gao Zhu, Zaishuo Xia, Yubei Chen
We ask whether the representational hierarchy seen in perception, from local primitives such as edges to higher level structures such as parts and objects, can be established for m…
Cloning Deterministic Worlds: The Critical Role of Latent Geometry in Long-Horizon World Models
Zaishuo Xia, Yukuan Lu, Xinyi Li +2
A world model is an internal model that simulates how the world evolves. Given past observations and actions, it predicts the future physical state of both the embodied agent and i…
