  DARPA: Generating Actionable Understanding of Real-World Phenomena with AI

  DARPA seeks to develop schema-based AI capability to enhance reasoning about complex world events and generate actionable insights Rapid comprehension of world events is critical to informing national security efforts. These noteworthy changes in the natural world or human society can create significant impact on their own, or may form part of a causal chain that produces broader impact. Many events are not simple occurrences but complex phenomena composed of a web of numerous subsidiary elements – from actors to timelines. The growing volume of unstructured, multimedia information available, however, hampers uncovering and understanding these events and their underlying elements. “The process of uncovering relevant connections across mountains of information and the static elements that they underlie requires temporal information and event patterns, which can be difficult to capture at scale with currently available tools and systems,” said Dr. Boyan Onyshkevych, a program manager in DARPA's Information Innovation Office (I2O). The use of schemas to help draw correlations across information isn't a new concept. First defined by cognitive scientist Jean Piaget in 1923, schemas are units of knowledge that humans reference to make sense of events by organizing them into commonly occurring narrative structures. For example, a trip to the grocery store typically involves a purchase transaction schema, which is defined by a set of actions (payment), roles (buyer, seller), and temporal constraints (items are scanned and then payment is exchanged). To help uncover complex events found in multimedia information and bring them to the attention of system users, DARPA created the Knowledge-directed Artificial Intelligence Reasoning Over Schemas (KAIROS) program. KAIROS seeks to create a schema-based AI capability to enable contextual and temporal reasoning about complex real-world events in order to generate actionable understanding of these events and predict how they will unfold. The program aims to develop a semi-automated system capable of identifying and drawing correlations between seemingly unrelated events or data, helping to inform or create broad narratives about the world around us. KAIROS' research objectives will be approached in two stages. The first stage will focus on creating schemas from large volumes of data by detecting, classifying and clustering sub-events based on linguistic inference and common sense reasoning. Researchers taking on this challenge will apply generalization, composition and specialization processes to help generate schemas that describe both simple and complex events, sequence multiple schemas together to understand key contextual elements like roles and timelines, and apply domain-specific knowledge to tailor the analysis for a particular need. The second stage of the program will focus on applying the library of schemas created during stage one to multimedia, multi-lingual information to uncover and extract complex events. This stage will require identifying events and entities, as well as relationships among them to help construct and extend a knowledge base. DARPA will hold a Proposers Day on January 9, 2019 from 10:00am to 2:30pm (EST) at the Holiday Inn at Ballston, 4610 N. Fairfax Drive, Arlington, Virginia 22203 to provide more information about KAIROS and answer questions from potential proposers.

The second stage will apply those schemas to new information to uncover and extract complex events, as well as relationships among them, to help construct and extend a knowledge base. https://www.darpa.mil/news-events/2019-01-04

  DoD Stands Up New Biotech Manufacturing Center: Griffin

  WASHINGTON: DoD is opening a new manufacturing innovation center dedicated to biotechnology to figure out how to replicate “nature's manufacturing plant” on an industrial scale, Pentagon research and engineering head Mike Griffin says. This is “a key new initiative,” Griffin stressed. The idea, he said at the annual McAleese conference, is “to learn how to do in an industrial way what nature has done for us in so many areas of things that we harvest and mine and use ... now that we are beginning to learn how to manipulate genomes.” Such technology could lead to DoD creating its own fuel using synthetic biology methods, for example. This would be a leap beyond ongoing efforts by DARPA that Sydney has widely reported, designed to protect soldiers against an enemy's biotech weapons. “This is a nascent technical area in the world, and especially in the United States,” Griffin told the audience here. “We want the national security community to be out in front on this.” The new center will be the ninth so-called ManTech center, designed to help overcome the so-called ‘valley of death' between research and commercialization by reducing risks. It will be the second ManTech center with a biotech focus: The first, BioFabUSA in New Hampshire, opened in 2016 to develop next-generation manufacturing techniques for repairing and replacing cells and tissues, which for example could lead to the ability to make new skin for wounded soldiers. Griffin elaborated on several other key areas for his two-year old office. DARPA is investing $459 million in the 2021 budget for AI Next, a “campaign” aimed at automating critical DoD business processes; improving the reliability of Artificial Intelligence systems; and enhancing the security of AI and machine learning tech. Griffin said his office is also “working with the Joint Artificial Intelligence Center (JAIC) under the CIO to bring about what we're calling AI Now: what can we do with AI that can get into the field and bring value to the national security community today, and the next day.” On 5G newtorks, he said that his deputy Lisa Porter is in charge of efforts to “figure out how we can use 5G to press our military advantage” and to protect US military networks. DoD launched that effort in 2019, with a $53 million reprogramming, he said. Congress added $200 million in the 2020 appropriations act, he added, and DoD is asking for $484 million in the 2021 budget. A key to future 5G networks and communications will be spectrum sharing, Griffin stressed. “There is no green field spectrum left,” he said, so DoD will have to figure out how to share spectrum to keep up with both its own demand and deal with pressure from commercial industry for it to give up spectrum. https://breakingdefense.com/2020/03/dod-stands-up-new-biotech-manufacturing-center-griffin
