AI总结:

本文通过三个人类相似性判断数据集考察神经网络表征与人类心理表征的对齐因素,发现训练数据和目标函数比规模与架构更关键,且单纯扩展规模不足以获得人类级概念表征。

摘要:

如今的计算机视觉模型在各种视觉任务上达到了人类或接近人类的性能水平。然而,它们的架构、数据和学习算法在许多方面不同于产生人类视觉的那些因素。在本文中,我们研究了影响神经网络所学习表征与从行为反应推断出的人类心理表征之间对齐程度的因素。我们发现,模型规模和架构对与人类行为反应的对齐基本没有影响,而训练数据集和目标函数的影响都要大得多。这些发现在使用两种不同任务收集的三个人类相似性判断数据集上是一致的。从一个数据集的行为反应中学习到的神经网络表征线性变换,显著提高了与另外两个数据集上人类相似性判断的对齐程度。此外,我们发现一些人类概念(如食物和动物)能被神经网络很好地表征,而其他概念(如皇室或与运动相关的对象)则不能。总体而言,尽管在更大、更多样化的数据集上训练的模型比仅在 ImageNet 上训练的模型能更好地与人类对齐,但我们的结果表明,仅凭规模扩展不太可能足以训练出具有与人类所用概念表征相匹配的神经网络。

英文摘要:

Today's computer vision models achieve human or near-human level performance across a wide variety of vision tasks. However, their architectures, data, and learning algorithms differ in numerous ways from those that give rise to human vision. In this paper, we investigate the factors that affect the alignment between the representations learned by neural networks and human mental representations inferred from behavioral responses. We find that model scale and architecture have essentially no effect on the alignment with human behavioral responses, whereas the training dataset and objective function both have a much larger impact. These findings are consistent across three datasets of human similarity judgments collected using two different tasks. Linear transformations of neural network representations learned from behavioral responses from one dataset substantially improve alignment with human similarity judgments on the other two datasets. In addition, we find that some human concepts such as food and animals are well-represented by neural networks whereas others such as royal or sports-related objects are not. Overall, although models trained on larger, more diverse datasets achieve better alignment with humans than models trained on ImageNet alone, our results indicate that scaling alone is unlikely to be sufficient to train neural networks with conceptual representations that match those used by humans.
