What is opaque to outsiders is often obvious – even if implicit – to locals. Habitus aims to capture and make local knowledge available to military operators, providing them with an insider view to support decision making.
Artificial intelligence (AI) and machine learning (ML) systems have advanced significantly in recent years. Despite a wide range of impressive results, current AI is not intelligent in the biological sense. These systems are limited to performing only those tasks for which they have been specifically programmed and trained, and are inherently subject to safety hazards when encountering situations outside them.
Current artificial intelligence (AI) systems excel at tasks defined by rigid rules – such as mastering the board games Go and chess with proficiency surpassing world-class human players. However, AI systems aren’t very good at adapting to constantly changing conditions commonly faced by troops in the real world – from reacting to an adversary’s surprise actions, to fluctuating weather, to operating in unfamiliar terrain.
Serial Interactions in Imperfect Information Games Applied to Complex Military Decision Making (SI3-CMD) builds on recent developments in artificial intelligence and game theory to enable more effective decisions in adversarial domains. SI3-CMD will explore several military decision making applications at strategic, tactical, and operational levels and develop AI/game theory techniques appropriate for their problem characteristics.
Over the last decade, wideband analog-to-digital converter (ADC) technology has improved in both bandwidth and resolution to a point that wideband RF sampling receivers are now a reality. However, wideband ADCs typically have less spur-free dynamic range as compared to their narrowband counterparts and are typically exposed to more signals simultaneously due to the wide bandwidth. Despite the advantages associated with more bandwidth, the dynamic range limitation can prevent the use of wideband receivers in multi-function applications that support wideband electromagnetic spectrum operations (EMSO).
