摘要

认知科学家经常从数据中推断多维表征。无论数据涉及文本、神经影像、神经网络还是人类判断,研究人员都会经常推断和分析潜在表征空间(即嵌入)。然而,潜在表征的属性(如预测性能、可解释性、紧凑性)取决于推理过程,而推理过程在不同的研究中可能会有很大差异。例如,维度并不总是全局可解释的,而且不同嵌入式的维度可能不容易比较。此外,将多维空间与所谓更丰富的表征格式(如图表征)对立起来会产生误导。我们回顾了认知科学中不同的维度概念对如何使用和解释这些潜在表征的影响。

The Dimensions of dimensionality.

Cognitive scientists often infer multidimensional representations from data. Whether the data involve text, neuroimaging, neural networks, or human judgments, researchers frequently infer and analyze latent representational spaces (i.e., embeddings). However, the properties of a latent representation (e.g., prediction performance, interpretability, compactness) depend on the inference procedure, which can vary widely across endeavors. For example, dimensions are not always globally interpretable and the dimensionality of different embeddings may not be readily comparable. Moreover, the dichotomy between multidimensional spaces and purportedly richer representational formats, such as graph representations, is misleading. We review what the different notions of dimension in cognitive science imply for how these latent representations should be used and interpreted.

期刊介绍: Essential reading for those working directly in the cognitive sciences or in related specialist areas, Trends in Cognitive Sciences provides an instant overview of current thinking for scientists, students and teachers who want to keep up with the latest developments in the cognitive sciences. The journal brings together research in psychology, artificial intelligence, linguistics, philosophy, computer science and neuroscience. Trends in Cognitive Sciences provides a platform for the interaction of these disciplines and the evolution of cognitive science as an independent field of study.
