Lifelong Learning Machines (L2M)

Mr. Ted Senator

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. The issue is further limiting to DoD applications, where situations can be unpredictable and the ability to react quickly and adapt to dynamic circumstances is of primary importance.

The Lifelong Learning Machines (L2M) program seeks to achieve paradigm-changing developments in AI architectures and ML techniques. The program seeks to develop systems that can learn continuously during execution and become increasingly expert while performing tasks, are subject to safety limits, and apply previous skills and knowledge to new situations - without forgetting previous learning.

L2M consists of two technical areas. The first concentrates on the development of complete systems and their components; the second brings together researchers with diverse expertise to explore biological mechanisms that underlie learning, which will be translated into a new generation of computational architectures, mechanisms, and algorithms. Discoveries in both technical areas are expected to generate new methodologies that will allow AI systems to learn and improve during tasks, apply previous skills and knowledge to new situations, incorporate innate system limits, and enhance safety in automated assignments.

Selected DARPA Achievements

DARPA collaborated with industry on stealth technology.
DARPA’s Stealth Revolution
In the early days of DARPA’s work on stealth technology, Have Blue, a prototype of what would become the F-117A, first flew successfully in 1977. The success of the F-117A program marked the beginning of the stealth revolution, which has had enormous benefits for national security.
DARPA microelectronics gave rise to today's GPS devices.
Navigation in the Palm of Your Hand
Early GPS receivers were bulky, heavy devices. In 1983, DARPA set out to miniaturize them, leading to a much broader adoption of GPS capability.
First rough conceptual design of the ARPANET.
Paving the Way to the Modern Internet
ARPA research played a central role in launching the Information Revolution. The agency developed and furthered much of the conceptual basis for the ARPANET—prototypical communications network launched nearly half a century ago—and invented the digital protocols that gave birth to the Internet.
