AI总结:

本文探讨了视觉模型中人类样粗粒物体表示的形成机制,通过实验发现资源限制而非特定偏见驱动该现象,并提出简单方法提升物理高效的表示。

摘要:

人类似乎用粗粒、体积型的物体来直观地进行物理预测,这种物体平滑凹陷,以牺牲精细的视觉细节来换取高效的物理预测,但其内部结构仍 largely 未知。相比之下,分割模型优化像素准确的掩码,可能与这种物体不一致。我们问这些模型是否以及何时能够获得人类样物体。使用时间到碰撞(TTC)行为范式,我们引入了一个比较流程和对齐度量,然后通过剪枝改变模型训练时间、大小和有效容量。在所有操作中,与人类行为的对齐度遵循反U形曲线:小/短暂训练/剪枝模型会过度分割成块;大/完全训练模型会过度分割,边界波动;而中间的理想物体粒度''最符合人类。这表明人类样粗粒物体的出现源于资源限制而非特定偏见,并指出简单的调节器——早期检查点、适度的架构、轻剪枝——可以激发物理高效的表示。我们将这些结果置于资源理性账户中,平衡识别细节与物理可及性。

英文摘要:

Humans appear to represent objects when reasoning about physics with coarse, volumetric "bodies" that smooth concavities, trading fine visual detail for efficient physical predictions. Yet, the structure of these representations remains largely unknown. Segmentation models, in contrast, are trained for pixel-accurate masks that may misalign with such bodies. We ask whether and when these models nonetheless acquire human-like object representations. Using a time-to-collision (TTC) and change detection (CD) behavioral task with data from 178 and 50 human participants, respectively, we introduce a pipeline and an alignment metric to compare the visual representations of segmentation models to those of humans. We do this systematically on multiple architectures (DINOv2, SegFormer, DeepLabV3+, and UPerNet), varying their size and training time. We find that briefly trained models segment objects too coarsely, aligning poorly with humans, while fully trained models segment objects too finely. For each model, there is an intermediate training regime that best matches the coarse bodies observed in human behaviour, and larger models tend to reach it earlier. We show these bodies emerge under resource constraints in general-purpose vision models, providing computational support to resource-rational accounts of human cognition. This work provides a foundational framework for testing alignment between vision models and humans and shows there is a growing gap between the state-of-the-art in artificial intelligence and human cognition, driven by scaling model size and training.
