ArXiv

Analysis

This paper addresses the problem of feature redundancy and inconsistency in sparse autoencoders (SAEs), which hinders interpretability and reusability.

It addresses the computational and memory limitations of fixed-length tokenization by dynamically aggregating image tokens into variable-sized patches. The core innovation lies in using next-token prediction entropy to guide the merging of tokens, leading to reduced token counts, lower FLOPs, faster convergence, and improved FID scores compared to baseline models. This is significant because it offers a way to scale autoregressive models to higher resolutions and potentially improve the quality of generated images.

    DPAR reduces token count by 1.81x and 2.06x on Imagenet 256 and 384 generation resolution respectively, leading to a reduction of up to 40% FLOPs in training costs. Further, our method exhibits faster convergence and improves FID by up to 27.1% relative to baseline models.

    Analysis

    This paper addresses a critical challenge in intelligent IoT systems: the need for LLMs to generate adaptable task-execution methods in dynamic environments. The proposed DeMe framework offers a novel approach by using decorations derived from hidden goals, learned methods, and environmental feedback to modify the LLM's method-generation path. This allows for context-aware, safety-aligned, and environment-adaptive methods, overcoming limitations of existing approaches that rely on fixed logic. The focus on universal behavioral principles and experience-driven adaptation is a significant contribution.

    DeMe enables the agent to reshuffle the structure of its method path-through pre-decoration, post-decoration, intermediate-step modification, and step insertion-thereby producing context-aware, safety-aligned, and environment-adaptive methods.
