Continuous Engineering and Deep Learning for Trustworthy Autonomous Systems

Deep learning has developed into a mature technology and it is nowadays an essential part in systems that may include timing and cyber-physical components, such as self-driving cars, autonomous control systems in medical applications and so on. We call these systems learning-enabled autonomous systems and we focus on key challenges in their design and development, which lie in the intersection of the two H2020 research projects that jointly organize this one-week summer school with prominent invited speakers and hands-on sessions on related tools and state-of-the-art industrial technologies.

The OpenDR project1 is focused on developing a modular, open and non-proprietary toolkit for core robotic functionalities by harnessing deep learning to provide advanced perception and cognition capabilities, meeting in this way the general requirements of robotics applications in various applications areas, such as healthcare, agri-food, and agile production. To this end, OpenDR is developing state-of-the-art lightweight and high resolution-enabled deep learning methods for core robotic functionalities, while investigating ways to integrate perception and action through active perception approaches.

The FOCETA project2 is focused on the problems associated with the analysis of the systems’ safety, security and performance in complex and often unpredictable environments given the fact that deep learning components are particularly sensitive to cyber-security threats and possible deviations from the system’s operational design domain. In addition to having continuously evolving requirements, we also need to support updates in the learning components and continuous testing/verification of the system under design. FOCETA invests in state-of-the-art formal methods for the continuous verification and validation of the systems, as well as for their deep learning components.

The summer school will host invited talks by distinguished researchers and industrial experts, as well as talks by the project participants that will reflect the achievements in the two ongoing projects.

Introductory lecture to Deep Learning, covering Multilayer Perceptron-like architectures as well as Convolutional Neural Networks.

Analysis of sequential data (e.g., time-series, image sequences) requires the underlying machine/deep learning models to be able encode temporal information and encode temporal dynamics. This cannot be efficiently done by using the standard neural network types (multilayer Perceptrons). In this lecture we will introduce two types of deep learning models that can efficiently model temporal dynamics following two different approaches. We will start by describing the basics of Recurrent Neural Networks (RNNs) which are designed to operate on sequential data, and we will proceed to describe more sophisticated neural network types addressing some of the limitations of RNNs, i.e., the Long- Short-Term Memory (LSTM) networks. We will also describe a modern neural network type which exploits the idea of self-attention in order to model the dependencies between items in its inputs called Transformers. Transformers are currently the state-of-the-art solution for many problems in computer/robot vision, and in particular their variant called Visual Transformers (ViTs).

Introducing the OpenDR project and toolkit, which will be further explored in the hands-on workshops.

Mobile manipulation remains a critical challenge across both service and industrial settings and is a key component to visions such as household assistants. But for this it requires the combination of a wide range of capabilities, such as perception and exploration in unknown environments while controlling large, continuous action spaces for simultaneous navigation and manipulation. In this talk I will first provide an overview of the main challenges and current benchmarks. I will then summarize and walk through the pipelines of current state-of-the-art approaches with a focus on both the high-level task learning and the low-level motion execution on robotic agents. Lastly, I will discuss potential paths forward and ways to integrate these low- and high-level components.

Deep Learning methods overview for object detection in images and object tracking in videos. Seminal works after DL's advent, state-of-the-art methods and future horizons.

Tuesday Oct 4th

While detection and tracking of objects in visual data (i.e., images and videos) has seen a lot of attention due to the wide availability of cameras and their use in multiple applications, objects in the real world and relationships among them are better described in 3D. While 3D sensors (like Lidars) are more expensive compared to high-end cameras and they are not widely available, there are applications in which they have received a lot of attention, like autonomous vehicles. In this lecture, we will describe the problems of 3D object detection and tracking, their challenges, and a number of recently proposed methodologies.

Decline of natural habitats and species continues worldwide due to various threats ranging from pollution and urbanization to intensive land use and climate change. If the problems are not addressed, this will have serious impacts on biodiversity and the vital services it provides. The urgent need for action has been recognized in international and national strategies that aim at reversing the degradations of ecosystems. Achieving these goals requires good understanding of natural ecosystems and their ongoing changes, but laborious manual monitoring cannot provide enough information. Machine learning has a lot of potential to assist in efficiently gathering information via modern large-scale autonomous environmental monitoring approaches to better understand and mitigate the negative impacts. This lecture will cover selected environmental monitoring tasks, introducing special challenges in these tasks and proposed deep learning-based solutions towards autonomous monitoring.

Recent developments in robotics and deep learning have enabled high-level robotic tasks to be learned from simulated or real data. In this talk, the task of robot grasping is covered, where a robot manipulator learns a grasping model from perceptual data, such as RGB-D or point clouds. Grasping is presented in context of robotics for agile production, thereby providing requirements and limitations that are relevant for deep learning in robotics. An overview of different approaches is given with special attention to the evaluation of robotic object grasping and the potential follow-step of object manipulation.

Simulation environments have always been a vital part of robotics research, providing tools for modelling and testing novel concepts and algorithms. The aim of this presentation is to introduce its audience to the main components of modern robotic simulators, as well as to the types of simulations established by the robotics community over the years. A wide range of robotic simulators will be reviewed, highlighting the pros and cons of each. Finally, applications of these simulators in robotics research, including those related to deep learning willl be presented.

Publishing and sharing simulation research results may require complex setup instructions and heavy dependencies installation. Webots eases this task with integrated functionalities to publish simulations on the web that can be viewed by reviewers and fellow researches in just few clicks. In this talk we will first provide a general overview of the Webots robotics simulation software and then focus on the 'webots.cloud' open-source webservice to share simulations online.

Wednesday Oct 5th

We will discuss some Siemens engineering solutions for ADAS and AV validation that combines simulation, physical testing and algorithms with focus on automated valet parking. The testing framework starts with real driving data, where baseline relevant and critical scenarios are extracted using safety and comfort requirements. These scenarios are then reconstructed into a digital twin environment with high-fidelity simulation models of vehicle dynamics, sensors and traffic, allowing further scenario generation for massive testing. The algorithms development of vehicle perception, SLAM, parking planning and control will also be discussed. Finally, we will show some testing results on simulation, physical vehicle (Siemens Simrod) and shadow testing using executable digital twin (xDT).

Deep Learning has been widely applied to many industrial applications but was also discovered various safety and security risks. The risks have led to not only the trustworthiness concerns but also intensive research in the past few years on how to determine if a deep learning model is safe in a rigorous way. This talk will briefly review existing efforts on certifying the safety of deep learning models, including methods based on formal verification, software testing, and reliability assessment. In addition to the technical review, we will also present a case study – based on an underwater vehicle -- on which we exercise the certification techniques. Finally, we will discuss theoretical and practical limitations of the certification techniques on deep learning models.

Use of Neural Networks in safety-critical systems like autonomous driving, robotics, or smart city applications requires robustness and resiliency to certain types of faults. Classification and object detection networks in such applications are widely used and accepted. While metrics and approaches to optimization of DNNs are well accepted and deployed in machine learning community, evaluation of object detection metrics caused by platform errors has not yet been widely performed. This talk will present common metrics and its performance in case of platform faults. Typically, neural networks (especially DNNs) are thought to be robust against hardware faults. Yet, in certain scenarios, faults could systematically impact system-level decisions in unforeseen ways. We will present such scenarios and simple effective mitigation techniques. Additionally, we will speculate how such approaches can find their way into applications of deployment of DNNs in safety-critical systems.

The enormous influence of systems deploying artificial intelligence, is contrasted by the growing concerns about their safety and the relative lack of trust by the society. To enable the broader deployment of AI-based systems, we need new methods to guarantee safety as well as to address the questions of explainability, predictability and accountability of the decision-making process of AI-based systems. Within this lecture, we will consider safety and accountability of AI from a formal methods perspective. We will discuss some ideas on how to tackle these challenges using formal methods, with a special focus on using correct-by-construction run-time enforcers called shields. In an interactive manner, we will discuss basic concepts of game theory and model checking to construct such shields and discuss their applications in several reinforcement learning settings. Additionally, we will touch upon the topic of formal modelling and analysis techniques for assessment of intention and responsibility of AI-based systems.

Proving the safe operation of autonomous driving and advanced driver assistance systems is one of the biggest challenges that the automotive domain is currently facing. Purely conventional test methods would fail by far due to the vast amount of test kilometers that are needed to argue about system safety guarantees. Scenario-based testing is a promising and widely studied method in order to address this challenge. In this talk, we will discuss why scenario-based testing can deliver an important brick for the safety argumentation of highly automated vehicles. Our argumentation will refer to requirements from recent safety standards such as ISO 21448 (SOTIF) or ISO 5083 (SaFAD), and will introduce the different testing strategies: coverage-driven testing, edge-case-testing, and expert-knowledge-testing. For several of these strategies candidate methods will be proposed, such as optimization-based critical scenario identification, and we will discuss open challenges, e.g., the derivation of suitable and modular scenario description languages. The talk will contain illustrative examples developed within our team to underline and demonstrate the problem setting.

Probabilistic programs (PPs), originally employed in cryptographic/privacy protocols and randomized algorithms, are now gaining momentum due to the several emerging applications in the areas of machine learning and AI. Probabilistic programming languages include native constructs for sampling distributions allowing to freely mix deterministic and stochastic elements. The resulting flexible framework comes at the price of programs with behaviors hard to analyze, leading to unpredictable adverse consequences in safety-critical applications. One of the main challenges in the analysis of these programs is to compute invariant properties that summarize loop behaviors. Despite recent results, full automation of invariant generation is at its infancy and only targets expected values of the program variables, which is insufficient to recover the full probabilistic program behavior. In this talk, we present some of the results of our project ProbInG that aims at developing novel and fully automated approaches to generate invariants over higher-order moments and the value distribution of program variables, without any user guidance.

As the hype around the imminent mass deployment of fully Automated Driving Systems (ADS) on public roads recedes, industry and government agencies are facing the challenge of how to assess and certify safety of ADS. The problem is challenging primarily due to the unpredictable nature of driving on open public roads. If anything can happen at any time, then what are you supposed to test and assure against? We argue that testing ADS must be driven by requirements. Requirements must capture not only the minimum desired performance of system components as part of the ADS performance, but also system level performance, e.g., compliance with traffic rules and regulations. In this presentation, we provide an overview of how such requirements can be formalized in temporal logics. Then, we demonstrate how these requirements can be used for monitoring as well as for search-based testing in ADS. In addition, we introduce a new temporal logic specifically designed for perception systems. Our ADS requirements driven test generation framework Sim-ATAV based on S-TaLiRo and Webots is open source and publicly available.

Deep learning has gained unprecedented rapid popularity in computer science in recent years. It is used in tasks that were previously considered highly challenging for computers, such as speech and image recognition and natural language processing. While deep learning is often associated with complicated tasks, we look at the much more mundane task of refining a system behavior through control that is constructed with the use of learning techniques. We compare the use of deep learning for this task with other techniques such as automata learning and genetic programming.

Designing today’s smart, connected products is challenging. Engineers developing mechanical hardware, electronics, and software components must coordinate their work, so it all fits seamlessly together. Digital twins can deliver value here by bridging these components, ensuring superior collaboration, and speeding up the digital transformation implementation. In this lecture, we introduce two well-established industrial standards that can be used in building interconnect fabric for digital twins and demonstrate their interoperability with industrial case-studies: TLM (Transaction Level Modelling) standard which is a well-established standard in the EDA industry. It is already baked into two key IEEE standards which are key to most simulation use models in the industry, namely the IEEE 1800 SystemVerilog standard and the IEEE 1666 SystemC standard and FMI (Functional Mock-up Interface) which is a tool independent standard to support model exchange, scheduled execution and co-simulation of dynamic models.

OpenDrive and OpenScenario standards are becoming increasingly important in the development and testing of autonomous vehicles. The OpenDrive standard is used for road network description, whereas OpenScenario describes the behavior of road users in a scenario. The standardization of such data enables reuse of data across industry partners, as well as co-simulation of multiple tools. The standards also empower regulatory bodies and government authorities, together with industry partners, to create unambiguous scenario libraries for the testing and safety-certification of autonomous vehicles. This workshop presents the support for OpenDrive and OpenScenario standards in the autonomous vehicle simulation platform, Simcenter Prescan. We demonstrate how a virtual validation workflow in Simcenter Prescan is defined based on OpenDrive and OpenScenario data.

The automatic synthesis of policies for robotic-control tasks through reinforcement learning relies on a reward signal that simultaneously captures many possibly conflicting requirements. In this paper, we introduce a novel, hierarchical, potential-based reward-shaping approach (HPRS) for defining effective, multivariate rewards for a large family of such control tasks. We formalize a task as a partially-ordered set of safety, target, and comfort requirements, and define an automated methodology to enforce a natural order among requirements and shape the associated reward. Building upon potential-based reward shaping, we show that HPRS preserves policy optimality. Our experimental evaluation demonstrates HPRS's superior ability in capturing the intended behavior, resulting in task-satisfying policies with improved comfort, and converging to optimal behavior faster than other state-of-the-art approaches. We demonstrate the practical usability of HPRS on several robotics applications and the smooth sim2real transition on two autonomous-driving scenarios for F1TENTH race cars.
