COLUMBUS, Ohio--(BUSINESS WIRE)--Battelle is combining years of brain-computer interface (BCI) projects, such as NeuroLife®, with its expertise in machine learning and artificial intelligence under a new award from the federal government's forward-thinking government agency, the Defense Advanced Research Projects Agency (DARPA). The award is part of DARPA's Artificial Intelligence Exploration program called Intelligent Neural Interfaces.
Using terabytes of neural data gathered in the past five years during NeuroLife sessions, Battelle Senior Data Scientist David Friedenberg and his team will build new decoding algorithms to make neural interfaces more robust over long periods of time.
The BCI systems typically rely on a decoder that monitors brain activity and then translates it into actions—in the case of NeuroLife, those signals are sent to a special sleeve that uses electrodes to stimulate muscles to evoke hand movement. However, the decoders require significant and time-consuming calibration to learn the mapping between the brain data and the user's intended action.
In June, the Battelle team began work on a $1 million, 18-month project that will try to solve longstanding problems with decoder optimization and maintenance while improving accuracy and robustness. To accomplish this goal, Battelle will develop a hybrid approach for stable long-term neural decoding using end-to-end deep neural network decoders to learn optimal features from the raw electrode recordings. In addition, using third-wave AI approaches, Battelle will develop models that account for changing context and continuously adapt accordingly. This allows for adjusting both the features and the decoder on-the-fly during normal system use to counteract non-stationarities and instabilities in the signal without requiring the user to intervene and recalibrate the system.
The next evolution of BCIs will occur as the systems move from the lab into the real lives of users. “We want these systems to require less training and be more robust to interruptions and interference,” said Friedenberg. “We want to develop optimal decoders that automatically and continuously adapt to each individual and the BCI they're using.”

Jen Judson WASHINGTON — The U.S. Army's ambitious first Project Convergence, an exercise that measured the progress of the service's modernization strategy within its future operational concept, concluded last month, but the service already has a sense of what it wants to accomplish in 2021. The series of exercises and experiments that made up the Project Convergence “campaign of learning” took place at Yuma Proving Grounds, Arizona. The event, held over a six-week period in the harsh desert at America's southwest border, was deemed the most important Army event outside of global operations, and future annual iterations are expected to continue shaping the future force. “We're going to have even further transformation of the battlefield geometry,” Brig. Gen. Wally Rugen, who is in charge of future vertical lift modernization, told Defense News in an Oct. 6 interview ahead of the Association of the U.S. Army's annual conference. “We want to go deeper. We made it to 61.9 kilometers, across the forward line of troops in the scenario we fought in 2020,” Rugen said. “We will want to go farther than that.” The Army will also join forces with all of the other military services in 2021, according to Gen. John Murray, the head of Army Futures Command. It will be up to those other services the kinds of capabilities and technologies they each bring to the equation, but the intention is to have the Air Force's F-35 fighter jet integrated into the architecture of the operation. Earlier this month, the Army and the Air Force signed a two-year collaboration agreement to develop a concept for Joint All-Domain Command and Control, or JADC2, which carries over the Army's future war-fighting doctrine, “Multi-Domain Operations” — which is still in the concept phase — to the world of joint operations. JADC2 essentially connects sensors to shooters — which was the bread and butter of Project Convergence this year — across the joint force. The exercise involved about 500 people at Yuma; most were data collectors. The event represented a platoon-sized operation. But in 2021, according to Murray, an entire operational headquarters element will be brought in to drive the learning in terms of how “we organize and how we fight the capability in the future.” Additionally, the Army wants to bring in a multidomain task force from Joint Base Lewis-McChord in Washington state, which would likely be the centerpiece of Project Convergence 21, said Brig. Gen. John Rafferty, who leads the Army's long-range precision fires efforts, which is the service's top modernization priority. There will also be other operational units brought in “to help explore and to help test on a larger scale,” Rafferty told Defense News in an interview this month. Starting in 2021, the exercise will have a foreign flavor. The United Kingdom signed on to participate next year, Murray said, and Australia may join. In 2022, the focus of the exercise will build significantly in terms of involving coalition forces. The Army also plans to tie Project Convergence to other exercises happening at roughly the same time. For example, since the event has an objective to operate in denied and degraded environments, the Army's Position Navigation and Timing Assessment Exercise will likely be a part of Project Convergence in 2021. In its first year, the Army had elements from the modernization teams focused on future vertical lift, long-range precision fires, the next-generation combat vehicle, the network, and positioning, navigation and timing. Next year, more teams will join, including those dedicated to air and missile defense, soldier lethality, and the Synthetic Training Environment. The Army also plans to involve its developmental missile, meant to replace the Army Tactical Missile System for a long-range shot. The Precision Strike Missile — a weapon with an expected range of 500 kilometers — will likely have a test shot that aims to surpass that during Project Convergence. The missile has an aggressive test schedule next year. The Extended Range Cannon, or ERCA, which participated this year, will have new technology rolled in by 2021, Rafferty said. The service also plans to demonstrate the Excalibur Hit-to-Kill capability, which is one of the competitors for the Dual-Purpose Improved Conventional Munition replacement effort. “That really is the lethality component of ERCA at extended ranges,” he added. The future vertical lift team will bring its 20mm gun planned for its future attack reconnaissance aircraft to the event as well as its Modular Effects Launcher prototype, which will carry both lethal and nonlethal effects to deploy from the air, Rugen said. The Army has begun firing live rounds from the gun, and will fire roughly 285,000 rounds through it this fiscal year. The Air-Launched Effects, or ALE, capability played a critical role in Project Convergence this year, and is to return with increased capability and improved technology. “The lower tier of the air domain is decisive,” Rugen said. “I think '20 proved that yet again like it did in '19. We need a broader acceptance of that from the joint force and from defensewide. There is a capability to show up at the time and place of our choosing with vertical lift from relative sanctuary and have operational effects, and that's really what we intend to show in '21.” The network underpins everything at Project Convergence, and improvements will continue to be made so the network that shows up in 2021 is more robust and geared beyond what it was originally designed to do, which is to support a tactical brigade. “I think you'll see better discipline on our data management and message traffic, message formats, which, again, is going to help that machine-to-machine targeting,” Rugen said. To further improve the ground and air assets connectivity, there will be a few more waveforms incorporated “to see if they can produce the bandwidth we need.” The Army wants the mesh network established through ALEs to be “more resilient and have greater goals on distance,” he added. FIRESTORM is also expected to return next year. The system uses artificial intelligence to help select the optimal shooter for engagement. Surrogate robotic combat vehicles and an optionally manned fighting vehicle will continue to play a major role as well. The hope is also to bring in the Army's Integrated Air and Missile Defense Battle Command System, known as IBCS, which is currently undergoing development to connect sensors and shooters for the purpose of countering missile threats. The system recently completed a by-and-large successful limited-user test and will head into its initial operational test and evaluation in 2021. Murray noted that if the test and evaluation conflicts with the Army's schedule, the system will not participate in next year's Project Convergence, noting that the evaluation is a top priority for the program to remain on track. The Army is also hoping the Integrated Visual Augmentation System — which will provide soldiers with AI-enhanced goggles that assist with navigation, targeting, and advanced night and thermal vision — will be ready for next year's experimentation. Overall, the Army has collected “70-plus technologies” — to include a few capabilities from the Defense Advanced Research Projects Agency — that it might incorporate into the event, Murray said, noting not all 70 will end up participating. https://www.defensenews.com/digital-show-dailies/ausa/2020/10/12/transforming-battlefield-geometry-whats-to-come-in-project-convergence-2021/
