In this talk, we present how a population of autonomous agents can self-organise a dynamic inventory of concepts in an incremental and data-efficient manner through a series of situated communicative interactions. Concretely, we extend the approach by Nevens et al. (2020) by equipping agents in the population with novel mechanisms for inventing, adopting, and aligning their conceptual representations. Through these mechanisms, the agents construct personal and dynamic inventories of concepts, which allow them to solve a communicative task. We validate our methodology using the benchmark CLEVR dataset (Johnson et al., 2017). In this experiment, a population of ten agents participates in pairwise communicative interactions. In each interaction, a speaker wants to draw the attention of a listener to an object through a concept describing its shape, size, material, or colour. We demonstrate that the agents construct an inventory of concepts from the ground up, achieving near-perfect communicative success after 10,000 interactions. By eliminating the need for a tutor, the agents are given the freedom to select relevant feature channels for each concept. They thereby construct concepts that are optimally adapted for their environment and the task at hand. Furthermore, the emergent conceptual system can be used to both comprehend utterances and describe novel instances. Lastly, concepts are constructed incrementally, enabling agents to use their concepts effectively even after a single interaction.
