Machine learning has shown remarkable success across many application areas in recent years, leveraging advances in computing power and the availability of large sets of training data. It provides a tremendous opportunity to deploy data-driven systems in more complex and interactive tasks including personalized autonomy, agile robotics, self-driving vehicles, and smart cities. Despite dramatic progress, the machine learning community still lacks an understanding of the trade-offs and mathematical limitations of related technologies for a given domain, problem, or dataset.
Destroying bulk stores of chemical warfare agents (CWAs) and organic precursors is a significant challenge for the international community. Today, for example, there are no approaches that exploit chemistries that are truly agnostic in terms of the agents that can be processed. In addition, current approaches require transport of agents from the storage site to a neutralization site. Ensuring safe transport of the agent can add significant cost and time to the process.
The goal of All Together Now (ATN) is to develop theoretical protocols and experimental techniques that enable new collective atom regimes, leading to sensitivities approaching the ultimate fundamental limits of performance.
The Biological Control program seeks to support a wide range of potential Department of Defense (DoD) applications by enhancing understanding of the basic processes associated with biological network interactions, communication, and control. Leveraging technologies developed under this program would enable construction of systems that seek out and mitigate chemical and biological threats; lead to the development of novel biomaterials that increase the resilience of Navy ships and other DoD systems to biofouling; and support military readiness by synthesizing new pharmaceuticals to treat emerging diseases.
A rapidly increasing percentage of the world’s population is connected to the global information environment. At the same time, the information environment is enabling social interactions that are radically changing how and at what rate information spreads. Both nation-states and nonstate actors have increasingly drawn upon this global information environment to promote their beliefs and further related goals.
