BTC3D: Blended Tile Conditioning for Detail-Enhancing Image-to-3D Generation

Recent diffusion-based pipelines have achieved promising progress in image-to-3D synthesis. However, generating high-fidelity details remains challenging, especially when the input image contains rich details. Existing approaches often rely on globally encoded conditioning features, which compress spatial information a...

The SIGReg Objective as Variational Free Energy: A Theoretical Active-Inference Account of JEPA World Models

A correspondence theorem is proved that under the standard constant-noise encoder model and successful SIGReg enforcement, the gap vanishes, the objective becomes an exact information bottleneck, the surprise bound is preserved, and the latent goal cost becomes an exact proxy for AIF pragmatic value.
