Guardian Autonomy for Safe Decision Making

Air Guardian aims to advance AI and autonomy by developing algorithms and tools for augmenting and amplifying human decision making. The AI Guardian assists humans by suggesting actions using data from the past and fusing inputs from sensors and information sources. Support from an AI Guardian system is especially useful in the presence of surprises and complex situations. Guardian’s end-to-end machine learning algorithms learn from experts how to respond with common sense reasoning in highly dynamic and surprising situations. Our goal is to enable an agent to perceive its environment, identify short-term risks, reason about intentions and behaviors of its operator, and other cooperative and adversarial agents to determine the best course of action. This will lead to Guardian autonomy systems capable of anticipating potential hazardous situations in the future.

Transferring Multi-Robot Learning through Virtual & Augmented Reality for Rapid Disaster Response

This project seeks to develop a new framework and class of algorithms that allow unmanned aerial systems to learn complex multi-agent behavior in simulator environments, then seamlessly transfer their knowledge from simulation to real-world field environments. The team envisions a first responder system where a swarm of autonomous aircraft are virtually trained on how to navigate and cooperate in a simulation of a novel disaster area. The system then transfers the learning gained in the simulation to the real autonomous aircraft swarm. An aircraft deploys a large “mothership” ground station which releases these trained autonomous aircraft to automatically perform time-critical, labor-intensive tasks like surveying disaster areas and locating and identifying survivors.

Multimodal Vision for Synthetic Aperture Radar

Synthetic Aperture Radar (SAR) is a radar imaging technology capable of producing high-resolution images of landscapes. Due to its ability to produce images in all weather and lighting conditions, SAR imaging has advantages in Humanitarian Assistance and Disaster Relief (HADR) missions compared to optical systems. This project aims to improve human interpretability of SAR images, performance of SAR object detection and Automatic Target Recognition (ATR) by leveraging complementary information from related modalities (e.g., EO/IR, LiDAR, MODIS), simulated data, and physics-based models. Project findings and resulting technologies will be shared across the government enterprise to be beneficial in the HADR problem space where multiple partners across services may be able to exploit developed technology.

AI-Assisted Optimization of Training Schedules

In order to improve the immensely complex and time-consuming process of manually scheduling aircraft flights, this project aims at automating aircraft flight scheduling to improve scheduling efficiency and robustness in the presence of uncertainty. This will optimize training flight schedules while providing explainability and removing silos in decision-making. This technology enables schedulers to quickly and effectively re-build schedules in the presence of rapidly changing circumstances, vastly accelerating planning and decision cycles. While initially focused on aircraft flight scheduling, this technology applies to all complex resource-allocation tasks across many sectors.

Fast AI: Data Center & Edge Computing

Fast AI: Quick Development of Portable High-Performance AI Applications
The AI revolution has been enabled by the availability of vast amounts of labeled data, novel algorithms, and computer performance. But long computer-in-the-loop development cycles inhibit humans from inventing and deploying creative AI solutions. Moreover, the end of Moore’s has curtailed the historical ability of semiconductor technology to deliver performance. AI performance increasingly relies on hardware architecture, software, and algorithms. The Fast AI project focuses on developing a foundation for quickly building AI solutions, enabling performance and portability on both modern and legacy hardware platforms. We innovate in the areas of programming languages, compiler technologies, comprehensive instrumentation, analytical productivity tools, and parallel algorithms.

ML-Enhanced Data Collection, Integration & Outlier Detection
A core requirement for AI techniques to be successful is high quality data. Preparing systems to be “AI ready” involves collecting and parsing raw data for subsequent ingest, scan, query and analysis. This project will develop ML-enhance database technologies to reduce storing and processing costs while enabling data sharing amongst various database silos. Additionally, we will develop an outlier detection engine to identify temporal anomalies amongst complex event streams from multiple sources.

Conversational Interaction for Unstructured Information Access and Language Learning ​

Conversations Interaction for Unstructured Information Access

The AI Accelerator Natural Language Processing project aims to advance conversational agents, knowledge representation, and prediction algorithms on flat/text image data and on Air Force missions. As the field of artificial intelligence advances, as we memorialize more of our work in data, and find more devices in our homes, it’s crucial that people are able to interact with the technology in meaningful ways – as humans, language matters – especially in discovering information on digital systems. The goal is to advance the AI community with conversational interaction and knowledge extraction for open-domain conversation and into unstructured information.

The Earth Intelligence Engine

The Earth Intelligence Engine
The Earth Intelligence (EI) Engine for weather and climate includes a novel AI testbed platform to support rapid, effective decision-making and long-term, strategic planning and operations for USAF. Advances in AI help close the gap between AI researchers and available Earth systems data via a platform connecting data and models, novel algorithms, and image gap-filling tasks to bridge lower-quality to higher-quality weather and climate data sets. The EI Engine will provide the USAF with improved algorithms for anomaly detection; critical remote access to centralized Earth intelligence data; intuitive supercomputer visualizations of Earth intelligence for mission support; improved nowcasting weather forecasting for mission operations; and strategic location identifications affected by climate change to enhance resource allocation. The goal is to develop a platform, which provides global scale to high-resolution local scale Earth weather and climate data and visceral visualizations to better inform policy decision-makers and leaders in government and business.

Explainable Machine Learning
Despite their incredible performance, machine learning models remain inscrutable–we do not understand how or why they arrive at their conclusions. Consequently, it is impossible for us to attain confidence in models’ decisions, and to debug them should they malfunction. This “black-box” nature limits our ability to deploy and frugally maintain machine learning systems, especially in high-stakes contexts. This project approaches machine learning explainability with a radically new mindset: combining machine learning and human-computer interaction methodologies to make actionability for the actual users the primary objective. The goal is to identify criteria for explainable machine learning that will enable development of models with human- and task-aligned data representations and decision-making interfaces.

Continual and Few-Shot Learning
AI techniques have proven very successful in many critical applications such as object recognition, speech recognition, and others. However, these successes have relied on collecting enormous datasets and careful manual annotations. This process is expensive, time-consuming, and in many scenarios, enough data is not available. Transfer learning offers a solution to these problems by leveraging past data seen by a machine to solve future problems using only few annotated examples. This research focuses on challenges in transfer learning and aims at developing algorithms that can fundamentally learn from multiple heterogeneous tasks, moving beyond low-level task similarity to enable broader transfer across distinct tasks. Such algorithms will find general applicability in several areas, including computer vision and natural language processing, and will substantially reduce the dependence on large amounts of annotated data and consequently reduce costs and time for deployment and maintenance of AI systems.

Robust AI Development Environment
AI and machine learning (ML) methods have demonstrated enormous promise for USAF. Many existing ML algorithms often fail catastrophically, however, when data inputs or task objectives change from those encountered during algorithm training. This lack of reliability combined with the opaque nature of modern ML techniques makes it impossible to deploy machine learning systems confidently in mission-critical environments. Furthermore, the inability of a model to adapt to changing environments translates into the need for (often costly and difficult) model retuning whenever the environment changes. This research will focus on a robustness-centered approach to developing ML algorithms. Robust AI Development ENvironment (RAIDEN) prioritizes ML reliability, versatility, and adaptability. The models, framework, and algorithms provided by our effort will enable streamlined deployment of truly reliable and efficient ML systems.

Objective Performance Prediction & Optimization Using Physiological and Cognitive Metrics

This project brings together experts in biomedical instrumentation, signal processing, neurophysiology, psychophysics, computer vision, Artificial Intelligence (AI), and Machine Learning (ML), as well as Air Force pilots, to develop and test AI-based, multi-modal physiologic sensor fusion approaches for objective performance prediction and optimization. The project will leverage immersive virtual environments to train pilots and unobtrusively measure predictors of performance. A series of Challenge Datasets developed from the program will be used to engage the community. Partnering with multiple governmental research efforts and Air Education and Training Command’s myriad pilot training units, the team seeks to provide proof-of-concept by demonstrably accelerating pilot training timelines, producing “better pilots faster.” These methods for accelerating training can then be transferred to all modes of learning across many disciplines and any task requiring significant cognitive effort.

Robust Neural Differential Models for Navigation and Beyond

There are several different GPS-alternatives being researched across the DoD and civilian sectors to address a GPS alternative; however, each alternative comes with additional costs and use cases. Magnetic Navigation presents an alternative GPS system that relies on magnetic resonance of the Earth – a system that is largely known and unchanging – to navigate. Some of the current problems with magnetic navigation involve 1) reducing excess noise on the system, such as magnetic outputs from the Aircraft itself, 2) determining position at a real-time pace or speeds consistent with military systems, and 3) combining with other systems to present a full-alternative GPS system.  The present project looks into using robust neural differential models to solve magnetic navigation shortcomings and provide a viable alternative to GPS.
