Towards real-world capable spatial memory in the LIDA cognitive architecture
نویسندگان
چکیده
The ability to represent and utilize spatial information relevant to their goals is vital for intelligent agents. Doing so in the real world presents significant challenges, which have so far mostly been addressed by robotics approaches neglecting cognitive plausibility; whereas existing cognitive models mostly implement spatial abilities in simplistic environments, neglecting uncertainty and complexity. Here, we take a step towards computational software agents capable of forming spatial memories in realistic environments, based on the biologically inspired LIDA cognitive architecture. We identify and address challenges faced by agents operating with noisy sensors and actuators in a complex physical world, including near-optimal integration of spatial cues from different modalities for localization and mapping, correcting cognitive maps when revisiting locations, the structuring of complex maps for computational efficiency, and multi-goal route planning on hierarchical cognitive maps. We also describe computational mechanisms addressing these challenges based on LIDA, and demonstrate their functionality by replicating several psychological experiments.

Spatial Working Memory in the LIDA Cognitive Architecture
Human spatial representations are known to be remarkably robust and efficient, and to be structured hierarchically. In this paper, we describe a biologically inspired computational model of spatial working memory attempting to account for these properties, based on the LIDA cognitive architecture. We also present preliminary results regarding a virtual reality experiment, which the model is abl...

In this paper we present the LIDA architecture as a working model of cognition. We argue that such working models are broad in scope and address real world problems in comparison to experimentally based models which focus on specific pieces of cognition. While experimentally based models are useful, we need a working model of cognition that integrates what we know from neuroscience, cognitive s...

The representation paradigm used by a cognitive architecture helps to determine the kind of processes that it can perform more efficiently. Vector LIDA is a variation of the LIDA cognitive architecture that employs high-dimensional Modular Composite Representation (MCR) vectors as its main representation model and Integer Sparse Distributed Memory as its main memory implementation technology. T...
متن کاملMemory Systems for Cognitive Agents
The several different memory systems in human beings play crucial roles in facilitating human cognition. To build artificial agents that have cognitive capabilities similar to those of human beings, we have to develop these agents based on architectures modelling what we know of human cognition from neuroscience, psychology and cognitive science. In this paper we describe the various memory sys...
