• Title: On human-centred security: A new systems model based on modes and mode transitions
• Authors: Edwin J Beggs, John V Tucker, Victoria Wang,
• Abstract summary: We propose an abstract conceptual framework for analysing complex security systems. A mode is an independent component of a system with its own objectives, monitoring data, algorithms, and scope and limits. We formalise the conceptual framework mathematically and, by quantifying and visualising beliefs in higher-dimensional geometric spaces, we argue our models may help both design, analyse and explain systems.

• Abstract: We propose an abstract conceptual framework for analysing complex security systems using a new notion of modes and mode transitions. A mode is an independent component of a system with its own objectives, monitoring data, algorithms, and scope and limits. The behaviour of a mode, including its transitions to other modes, is determined by interpretations of the mode's monitoring data in the light of its objectives and capabilities -- these interpretations we call beliefs. We formalise the conceptual framework mathematically and, by quantifying and visualising beliefs in higher-dimensional geometric spaces, we argue our models may help both design, analyse and explain systems. The mathematical models are based on simplicial complexes.

• Co-designing heterogeneous models: a distributed systems approach [0.40964539027092917]
  This paper presents a modelling approach tailored for heterogeneous systems based on three elements. An inferentialist interpretation of what a model is, a distributed systems metaphor and a co-design cycle describe the practical design and construction of the model. We explore the suitability of this method in the context of three different security-oriented models.

• Discrete, compositional, and symbolic representations through attractor dynamics [51.20712945239422]
  We introduce a novel neural systems model that integrates attractor dynamics with symbolic representations to model cognitive processes akin to the probabilistic language of thought (PLoT) Our model segments the continuous representational space into discrete basins, with attractor states corresponding to symbolic sequences, that reflect the semanticity and compositionality characteristic of symbolic systems through unsupervised learning, rather than relying on pre-defined primitives. This approach establishes a unified framework that integrates both symbolic and sub-symbolic processing through neural dynamics, a neuroplausible substrate with proven expressivity in AI, offering a more comprehensive model that mirrors the complex duality of cognitive operations

  Vision systems to see and reason about the compositional nature of visual scenes are fundamental to understanding our world. The models learned to bridge the gap between such modalities coupled with large-scale training data facilitate contextual reasoning, generalization, and prompt capabilities at test time. The output of such models can be modified through human-provided prompts without retraining, e.g., segmenting a particular object by providing a bounding box, having interactive dialogues by asking questions about an image or video scene or manipulating the robot's behavior through language instructions.

  We present a modular simulation framework for modeling homogeneous multibody dynamical systems. An arbitrary number of modules can be combined to simulate systems of a variety of coupling topologies. We show that our models can be transferred to new system configurations lower with data requirement and training effort, compared to those trained from scratch.
