• Title: Predicting emergent linguistic compositions through time: Syntactic frame extension via multimodal chaining
• Authors: Lei Yu, Yang Xu
• Abstract summary: We develop a framework that exploits the cognitive mechanisms of chaining and multimodal knowledge to predict compositional expressions through time. We present the syntactic frame extension model (SFEM) that draws on the theory of chaining and knowledge from "percept", "concept", and "language" We show that multimodal SFEM predicts newly emerged verb syntax and arguments substantially better than competing models using purely linguistic or unimodal knowledge.

• Abstract: Natural language relies on a finite lexicon to express an unbounded set of emerging ideas. One result of this tension is the formation of new compositions, such that existing linguistic units can be combined with emerging items into novel expressions. We develop a framework that exploits the cognitive mechanisms of chaining and multimodal knowledge to predict emergent compositional expressions through time. We present the syntactic frame extension model (SFEM) that draws on the theory of chaining and knowledge from "percept", "concept", and "language" to infer how verbs extend their frames to form new compositions with existing and novel nouns. We evaluate SFEM rigorously on the 1) modalities of knowledge and 2) categorization models of chaining, in a syntactically parsed English corpus over the past 150 years. We show that multimodal SFEM predicts newly emerged verb syntax and arguments substantially better than competing models using purely linguistic or unimodal knowledge. We find support for an exemplar view of chaining as opposed to a prototype view and reveal how the joint approach of multimodal chaining may be fundamental to the creation of literal and figurative language uses including metaphor and metonymy.

  Large Language Models produce sequences learned as statistical patterns from large corpora. After initial training models must be aligned with human values, prefer certain continuations over others. We examine this practice of structuration as a two-way interaction between users and models.

  We propose rational meaning construction, a computational framework for language-informed thinking. We frame linguistic meaning as a context-sensitive mapping from natural language into a probabilistic language of thought. We show that LLMs can generate context-sensitive translations that capture pragmatically-appropriate linguistic meanings. We extend our framework to integrate cognitively-motivated symbolic modules.

• Geometry of Language [0.0]
  We present a fresh perspective on language, combining ideas from various sources, but mixed in a new synthesis. The question is whether we can formulate an elegant formalism, a universal grammar or a mechanism which explains significant aspects of the human faculty of language. We describe such a mechanism, which differs from existing logical and grammatical approaches by its geometric nature.

  Temporal grounding is the task of locating a specific segment from an untrimmed video according to a query sentence. We introduce a new Compositional Temporal Grounding task and construct two new dataset splits. We argue that the inherent structured semantics inside the videos and language is the crucial factor to achieve compositional generalization.

  We investigate the extent to which modern, neural language models are susceptible to syntactic priming. We introduce a novel metric and release Prime-LM, a large corpus where we control for various linguistic factors which interact with priming strength. We report surprisingly strong priming effects when priming with multiple sentences, each with different words and meaning but with identical syntactic structure.

  The activations of language transformers like GPT2 have been shown to linearly map onto brain activity during speech comprehension. Here, we propose a taxonomy to factorize the high-dimensional activations of language models into four classes: lexical, compositional, syntactic, and semantic representations. The results highlight two findings. First, compositional representations recruit a more widespread cortical network than lexical ones, and encompass the bilateral temporal, parietal and prefrontal cortices.

• Compositionality and Generalization in Emergent Languages [42.68870559695238]
  We study whether the language emerging in deep multi-agent simulations possesses a similar ability to refer to novel primitive combinations. We find no correlation between the degree of compositionality of an emergent language and its ability to generalize. The more compositional a language is, the more easily it will be picked up by new learners.
