DARPA: Using AI to Build Better Human-Machine Teams

The inability of artificial intelligence (AI) to represent and model human partners is the single biggest challenge preventing effective human-machine teaming today. Current AI agents are able to respond to commands and follow through on instructions that are within their training, but are unable to understand intentions, expectations, emotions, and other aspects of social intelligence that are inherent to their human counterparts. This lack of understanding stymies efforts to create safe, efficient, and productive human-machine collaboration.

“As humans, we are able to infer unobservable states, such as situational beliefs and goals, and use those to predict the subsequent actions, reactions, or needs of another individual,” said Dr. Joshua Elliott, a program manager in DARPA's Information Innovation Office (I2O). “Machines need to be able to do the same if we expect them to collaborate with us in a useful and effective way or serve as trusted members of a team.”

Teaching machines social intelligence however is no small feat. Humans intuitively build mental models of the world around them that include approximations of the mental models of other humans – a skill called Theory of Mind (ToM). Humans use their ToM skill to infer the mental states of their teammates from observed actions and context, and are able to predict future actions based on those inferences. These models are built on each individual's existing sets of experiences, observations, and beliefs. Within a team setting, humans build shared mental models by aligning around key aspects of their environment, team, and strategies. ToM and shared mental models are key elements of human social intelligence that work together to enable effective human collaboration.

DARPA's Artificial Social Intelligence for Successful Teams (ASIST) program seeks to develop foundational AI theory and systems that demonstrate the basic machine social skills necessary to facilitate effective machine-human collaboration. ASIST aims to create AI agents that demonstrate a Machine ToM, as well as the ability to participate effectively in a team by observing and understanding their environment and human partners, developing useful context-aware actions, and executing those actions at appropriate times.

The agents developed under ASIST will need to operate across a number of scenarios, environments, and other variable circumstances, making the ability for them to evolve and adapt as needed critical. As such, ASIST will work to develop agents that can operate in increasingly complex environments, adapt to sudden change, and use observations to develop complex inferences and predictions.

During the first phase of the program, ASIST plans to conduct experiments with single human-machine interactions to see how well the agents can infer human goals and situational awareness, using those insights to then predict their teammate's actions and provide useful recommended actions. As the program progresses, the complexity will increase with teams of up to 10 members interacting with the AI agents. During these experiments, ASIST will test the agents' ability to understand the cognitive model of the team – not just that of a single human – and use that understanding to develop appropriate situationally relevant actions.

Full details on the program can be found in the Broad Agency Announcement (BAA) solicitation, which has been posted to the Federal Business Opportunities website, https://www.fbo.gov/index?s=opportunity&mode=form&id=9d4acf0aba98916288a541bd07810004&tab=core&_cview=1

    After the US Navy’s Bonhomme Richard catastrophe, a far-reaching crackdown on fire safety

    By: David B. Larter WASHINGTON – U.S. Navy brass is telling sailors and contractors to put fire safety at the center of their work in the shipyards and on the waterfront in the wake of a catastrophic fire aboard the amphibious assault ship Bonhomme Richard. As Naval Sea Systems Command continues its formal assessment of the damage to Bonhomme Richard, the Navy has both sailors across the organization and contractors working on the ships reviewing their procedures and ensuring they are doing everything possible to prevent a second tragedy. Adm. Michael Gilday, the chief of naval operations, said the enterprise-wide effort was to prevent a similar event from taking place, a lesson he drew from the Navy's response to a string of accidents in 7th Fleet in 2017. “Could there be another Bonhomme Richard waiting to happen? If you go back to 2017, who would have predicted we'd have had two collisions of that magnitude within a month?” Gilday said in a July 16 interview with Defense News. “So, I'm not waiting for ‘No. 2' to decide we have a trend here. In a situation like this, one incident is enough for me to determine that there could be a trend and I'm not going to leave it to chance that there might be.” In the wake of the fire, he ordered fleet commanders to send a lengthy list of requirements to the waterfront, including a mandate to do fire safety inspections of every space on every ship. So-called “zone inspections” of each space on a ship are generally spread out over months, rather than packed into a week. The orders also included reviewing maintenance records on all damage control equipment – such as fire hoses and fire main connections, fire extinguishers, fixed fire suppression systems and firefighting gear – and ensure it is 100 percent accounted for. Additionally, each in-port duty section (a rotating group of sailors from the crew designated to stay on board the ship for 24 hours) was required to undergo a formal assessment as to their proficiency in firefighting and validate that they were properly manned to be effective. Contractors and shipbuilders have also been warned by the Navy to take fire safety seriously. In the days following the Bonhomme Richard fire, two minor fires – one on board the amphibious assault ship Kearsarge at General Dynamics NASSCO shipyard and another on the Navy's future carrier John F. Kennedy at Newport News shipbuilding – have curtailed work and prompted a doubling down on safety. In a Friday letter, Navy's top acquisitions official James Geurts told shipbuilders and contractors to take Bohnomme Richard as a lesson. "Anyone who steps aboard our ships must be ever vigilant about ensuring fire safety," Geurts wrote. "I urge you to use [the recent fire] to ensure that our work spaces are clean, that unnecessary clutter is removed, that all fire safety measures are being followed and that there is unrestricted access to firefighting and damage control equipment." ‘Gutted' The safety crackdown follows the Navy's worst in-port disaster since the 2012 fire on board the attack submarine Miami, which suffered a major conflagration while in deep maintenance at Portsmouth Naval Shipyard in Maine. That incident was later determined to be arson. The Bonhomme Richard fire, which experts fear may have damaged the “big deck” amphib beyond repair, raised troubling questions about how prepared sailors are to combat one of their most fearsome enemies: a shipboard fire, a threat they are trained to deal with from their earliest days in Boot Camp. In a letter this week from Gilday to all Navy flag officers and top enlisted leaders, he detailed how a series of explosions and a 1,200-degree inferno caused “extensive damage” to 11 of Bonhomme Richard's 14 decks. “There is fire and water damage, to varying degrees, on 11 of 14 decks,” Gilday wrote. “With the flight deck as a reference, I walked sections of the ship 5 levels below and had the opportunity to examine the superstructure. “The island is nearly gutted, as are sections of some of the decks below; some perhaps, nearly encompassing the 844 ft length and 106 ft beam of the ship ([Naval Sea System Command's] detailed assessment is ongoing). Sections of the flight deck are warped/bulging.” The fire on the Bonhomme Richard broke out the morning of July 12 while it was pierside in San Diego, California, undergoing maintenance. The blaze was aided by wind and explosions, Gilday wrote. “While response from the crew and federal firefighters was rapid, preliminary reports indicate there were two main factors that contributed to the intensity, scope, and speed of the fire,” Gilday wrote. “First was wind that fueled the fire as the vehicle storage area leads to the well deck, which opens to the air at the stern gate. The second were the explosions, one in particular, reportedly heard about 13 miles away. “The explosions, some were intense, and the uncertainty of their location and timing, led to a situation, that might have been under control late Sunday night, but expanded into a mass conflagration, spreading quickly up elevator shafts, engine exhaust stacks, and through berthing and other compartments where combustible material was present.” The Navy has launched dual investigations into the fire: A safety investigation, which are generally not released to the public so that witnesses can feel free to speak openly, and a more formal administrative investigation, which generally comes with disciplinary recommendations and are releasable to the public. https://www.defensenews.com/naval/2020/07/25/after-the-us-navys-bonhomme-richard-catastrophe-a-far-reaching-crackdown-on-fire-safety/

    DoD hands out $84 million in recovery funds for small drone makers and a space firm

    By: Aaron Mehta WASHINGTON — The U.S. Department of Defense announced Friday it is issuing $84.4 million in funding through the Defense Production Act to small unmanned technology, space and shipbuilding companies. The money, divided among seven different companies, will be used to “sustain and strengthen essential domestic industrial base capabilities,” per a Pentagon announcement. “These actions will help to retain critical workforce capabilities throughout the disruption caused by COVID-19 and to restore some jobs lost because of the pandemic.” The Defense Production Act has been in the spotlight in recent months, as it's served as a central tool in attempts by the Trump administration to increase production of personal protective equipment to combat the spread of the coronavirus, something critics say the administration was too slow to implement. Title III of the DPA gives the department the opportunity to fund what it sees as critical suppliers of the defense industry who might otherwise be at risk of closing. Although those authorities have been on the books for years, the department became more serious about using them following a 2018 landmark study of the defense industrial base that identified a number of sectors where small companies that provide key parts for America's arsenal could go out of business. The undersecretary of defense for acquisition and sustainment, Ellen Lord, previously identified shipbuilding, aviation and the small space sector as three areas that are suffering under the economic impacts from COVID-19. She has said her office will keep an eye on those sectors. That seems to have played out in the Pentagon's announcement about the $84.4 million in funding. Of the funding, $13.4 million went to five small unmanned systems companies. Funding was authorized and appropriated under the Coronavirus Aid, Relief and Economic Security Act, and awarded through the Defense Innovation Unit — the Silicon Valley technology hub for the Pentagon. The department claims the funding “saved 14 jobs, created 20 new positions, and will support continued advancement of capabilities providing the companies additional paths for recurring revenue.” Even before the economic damage from COVID-19, the department had identified small UAS manufacturers as a sector that needs to grow. Included in this latest funding are: AirMap, in Santa Monica, California, which received $3.3 million. The money will “aid product development and engineering support for integration of sUAS mission planning, post-mission analysis, and unmanned traffic management software.” ModalAI, of San Diego, California, which received $3 million to “develop their next generation U.S.-made flight controller that will enable advanced autonomy including GPS-denied navigation, and all-environment obstacle avoidance.” Skydio, in Redwood City, California, which received $4 million to “improve the flight controller hardware/software and data link for their sUAS so that highly capable components can be purchased and used across U.S. Government unmanned systems.” Graffiti Enterprises, located in Somerset, New Jersey, which was given $1.5 million to “modify their commercial data link for DoD's sUAS use including operation in restricted frequency bands, reduction in the size, weight, and power of the hardware, and software developments to improve security and resiliency of their data link.” Obsidian Sensors, from San Diego, California, which received $1.6 million to build a “low-cost, dual thermal sUAS camera that can be mounted onto a stabilization gimbal and then integrated and flown on small, packable, ISR systems.” In addition, the Pentagon awarded $15 million to LeoLabs, based in Menlo Park, California, to “ensure the continued viability of space surveillance capability through the operation and maintenance of a world-wide highly capable phased-array radar network.” The department said LeoLabs is the only domestic commercial supplier with the capability to meet requirements in this area. Last month, the Space Force invoked the DPA to get funding for six small space companies that were considered at risk, before it reversed those awards two weeks later. While those are all fairly small technology firms, the biggest dollar amount awarded was $56 million for ArcelorMittal Inc., a steel and mining company based in Chicago, Illinois. The funding, also from the coronavirus relief package, will be used to “protect” jobs impacted by the pandemic that are critical to military shipbuilding. Specifically, the investment will “expand ArcelorMittal's plate processing footprint and heat-treating capability, subsequently increasing its alloy steel plate production and ensure the U.S. Government gets dedicated long-term industrial capacity to meet the needs of the nation,” per the department. https://www.defensenews.com/industry/2020/07/10/dod-hands-out-84-million-in-recovery-funds-for-small-unmanned-companies-space-firm

    Israel Aerospace considering investment in drone maker Aeronautics

    JERUSALEM (Reuters) - State-owned defense contractor Israel Aerospace Industries (IAI) [ISRAI.UL] said on Tuesday it was in talks to invest in local drone maker Aeronautics (ARCS.TA). The talks were at an early stage, IAI said, and no financial details were disclosed. Meanwhile Aeronautics, which was searched on Monday by Israel Securities Authority investigators, said separately it was also talking to another unidentified group regarding the sale of its 50 percent stake in the surveillance and reconnaissance company Controp Precision Technologies. In August, Aeronautics rejected a 430 million shekel ($115 million) acquisition offer from IAI rival, state-owned Rafael Advanced Defense Systems, and businessman Avihai Stolero. Israel-based Aeronautics manufactures unmanned aerial vehicles for military surveillance and defense purposes, as well as for the commercial sector. On Monday, investigators from the market regulator searched Aeronautics' office, the company said. A court has placed a gag order on details of the investigation. It was not the first time Aeronautics has been probed by Israeli authorities. In August 2017, Aeronautics said the Defence Ministry had suspended the marketing and export license for one of the firm's attack drones to a single, significant customer in a foreign country. It denied it was at fault. Israeli media at the time reported that the ministry had opened an investigation into Aeronautics over whether during a demonstration in Azerbaijan one of its drones was used to attack a military position in the neighboring country of Armenia, and if so, who was at fault. In November that same year Israeli police said they were investigating one of the drone maker's deals but did not give details.
