Robust Neural Posterior Estimation and Statistical Model Criticism
Robust Neural Posterior Estimation and Statistical Model Criticism NeurIPS 2022 Computer simulations have proven a valuable tool for understanding complex phenomena across the sciences. However, the utility of simulators for modelling and forecasting purposes is often restricted by low data quality, as well as practical limits to model fidelity. In order to circumvent these difficulties, […]
Calibrating Agent-based Models to Microdata with Graphic Neural Networks
Calibrating Agent-based Models to Microdata with Graphic Neural Networks ICML 2022 Artificial Intelligence for Agent-based Modelling (AI4ABM) Workshop Calibrating agent-based models (ABMs) to data is among the most fundamental requirements to ensure the model fulfils its desired purpose. In recent years, simulation-based inference methods have emerged as powerful tools for performing this task when the […]
Making sense of synthetic environments through effective model integration
Improbable Defence’s research efforts aim to enable a new generation of multi-domain, multi-use synthetic environments that can bolster the security and national resilience of the UK and our allies. Over the coming weeks and months, we’ll be taking a closer look at some of the most intractable problems that both Improbable Defence and our partners […]

High Performance Simulation for Scalable Multi-Agent Reinforcement Learning
High Performance Simulation for Scalable Multi-Agent Reinforcement Learning ICML 2022 Artificial Intelligence for Agent-based Modelling (AI4ABM) Workshop Multi-agent reinforcement learning experiments and open-source training environments are typically limited in scale, supporting tens or sometimes up to hundreds of interacting agents. In this paper we demonstrate the use of Vogue, a high performance agent based model […]

New to defence? Seven things we learned coming into the sector Libby Penn, Chief Operating Officer Changing industries is not uncommon in the tech space. Many of us have worked in different areas whether that’s gaming, finance, health, sports, media. I myself have worked across tech companies in HR tech, fintech, augmented reality, even tech for […]
London, Exercise ARRCADE LIONHEART 2022: reimagining urban warfare
London, Exercise ARRCADE LIONHEART 2022: reimagining urban warfare The NATO 2022 Strategic Concept paints a stark portrait of a world rocked by ‘pervasive instability, rising strategic competition and advancing authoritarianism’. In an age of high-intensity, multi-domain urban operations, challenges such as these threaten to undermine the West’s values, security and prosperity. Exercises like ARRCADE LIONHEART […]
