摘要:

分布式模型提供了一种方便的方式来建模语义使用密集的嵌入空间从无监督学习算法。然而,密集嵌入空间的维度并没有被设计成类似于人类语义知识。此外,尽管神经认知研究表明语义与语言和感知都有很深的联系,但嵌入通常是从单一的信息源(通常是文本数据)构建的。在本文中,我们结合了来自最先进的分布模型的文本和基于图像的表示的多模态信息,使用联合非负稀疏嵌入产生稀疏的,可解释的向量。通过深入分析比较这些稀疏模型与人类衍生的行为和神经成像数据,我们证明了它们预测人类真实语义知识的可解释语言描述的能力。

英文摘要:

Distributional models provide a convenient way to model semantics using dense embedding spaces derived from unsupervised learning algorithms. However, the dimensions of dense embedding spaces are not designed to resemble human semantic knowledge. Moreover, embeddings are often built from a single source of information (typically text data), even though neurocognitive research suggests that semantics is deeply linked to both language and perception. In this paper, we combine multimodal information from both text and image-based representations derived from state-of-the-art distributional models to produce sparse, interpretable vectors using Joint Non-Negative Sparse Embedding. Through in-depth analyses comparing these sparse models to human-derived behavioural and neuroimaging data, we demonstrate their ability to predict interpretable linguistic descriptions of human ground-truth semantic knowledge.
