      <sec id="sec-1-1">
        <title>Strategy</title>
        <p>The Center operates by combining three key ingredients: research, assets, and technology
transfer. Research is carried out in several vertical areas and is experimentally supported by assets that,
once matured in terms of technology readiness, are then deployed in applied settings for technology
transfer. This model - which we refer to as TT-driven research - is circular in the sense that feedback
and empirical data gathered from collaborative engagements with industrial partners are subsequently
utilized to suggest future research directions. This ensures continuous relevance and maximized impact.
Furthermore, the assets are developed to be domain-independent, in order to support their application
in diferent sectors with limited efort invested in customization.</p>

      <title>2. Research Units</title>
      <p>The Center is structured around eight collaborative research units, which are presented below.
Software Engineering. This unit specialises in the development of robust and reliable software
systems. Research areas include Requirements Engineering and Software Testing, for complex
parametric systems, using automated reasoning based on search-based, AI-based, and formal techniques.
The unit developed and maintains a custom library for automated test case generation (EvoMBT) based
on metaheuristics, and machine learning techniques [1]. Applications focus on the railway domain
and manufacturing sectors [2, 3], with projects focusing on the definition of automated test generation
methodologies and tools to be applied to railway systems, the design and verification of autonomous
railway vehicles, and the testing and validation of extended reality applications via multi-agent systems.
Open Platforms and Enabling Technologies for the Internet of Things The unit focuses on
the development of intelligent, autonomous IoT infrastructures and platforms for highly distributed
applications, with a strong emphasis on digital agriculture. Activities include adapting AI techniques
for edge devices, integrating advanced robotics, and developing predictive models for irrigation [4]
and farm management. The team also explores data governance through decentralized blockchain
architectures and European data spaces. Key applications involve smart irrigation, food traceability [5],
and robust localization for autonomous agricultural robots [6]. OpenIoT aims to enhance eficiency,
sustainability, and data sovereignty through cutting-edge IoT and AI solutions.</p>
      <sec id="sec-2-1">
        <title>Formal Methods for System and Software Design The unit develops advanced formal methods to</title>
        <p>ensure the correctness, safety, and reliability of complex systems and software. A wide range of formal
verification techniques are explored and applied, including automated reasoning, contract-based design,
and runtime verification, with a focus on the rigorous verification and validation of cyber-physical
systems and AI-based systems.</p>
        <p>A core strength lies in symbolic model checking, an eficient technique for the automatic generation
of mathematical proofs of system and software correctness. In addition, the unit has established a
strong expertise in fault injection and model-based safety analysis, which are essential to evaluate the
reliability of the system and to analyze the efectiveness of safety mechanisms such as fault detection,
isolation, and recovery mechanisms.</p>
        <p>The unit develops and maintains a suite of formal verification tools, including MathSAT, nuXmv,
OCRA, and xSAP, widely adopted in safety-critical domains such as space systems, railway infrastructure,
automotive and avionics systems, energy systems, and industrial manufacturing. The unit collaborates
closely with industrial partners to apply formal methods to concrete real world problems and has a
strong track record of successfully applications in safety-critical domains (see, e.g., [7, 8, 9]).
Planning, Scheduling and Optimization This unit is focused on the research field of automated
planning and scheduling. This core problem is relevant in many diverse application sectors such as
manufacturing, logistics and robotics. In this area, the unit is active along the following three main
research directions. 1. State-of-the-art techniques for eficient optimal [ 10] and “satisficing” automated
temporal planning, also in combination with motion planning. 2. The combination of automated
temporal planning and reinforcement learning (RL) [11]. This research line is the core component of
the running STEP-RL ERC Starting Grant project. 3. The connection between formal methods and
planning, including some seminal works on the theoretical foundations of planning [12]. In addition to
these core research competences, the PSO unit is active in the technology transfer of solutions based
on finite-horizon scheduling and constraint optimization. Over the years, the unit developed a set of
software assets including the Unified Planning library, the TAMER planner, and the PySMT library.
Data Science for Industry and Physics This unit focuses on applying Data Science methodologies
and approaches for developing predictive models based on machine learning from heterogeneous data.
DSIP is actively collaborating with industrial partners and research organizations. DSIP is involved in
developing Deep Learning solutions for time series analysis and forecasting in the context of condition
monitoring and predictive maintenance for industrial processes. In the earth and climate sector, DSIP
is involved in projects ranging from machine learning applied to spatiotemporal data for weather
nowcasting and forecasting, Earth System Modeling, statistical downscaling, data quality, and anomaly
detection of observations. As for applications in physics, DSIP is developing Deep Learning solutions
for the data analysis of High Energy Physics experiments in the ATLAS collaboration at CERN and
Space Physics within the CSES-LIMADOU mission [13, 14, 15].
3D Optical Metrology This unit focuses on the science and engineering of precise 3D measurement
and modeling. Research areas include geomatics, metrology, 3D mapping, photogrammetry, and
geospatial data analytics. The unit’s R&amp;D outcomes support applications in territorial mapping, cultural
heritage documentation, industrial quality control, and digital twin creation. Key instrumentation

include FEROX (robotics and AI for automating wild berry harvesting), TRACENET (virtual
realitybased training for civil protection teams), USAGE (use of geospatial data to support the implementation
of various Green Dead priorities in diferent European cities) and 3D-4CH (a Competence Centre in 3D
Cultural Heritage).</p>
        <p>Technologies of Vision This unit focuses on advancing computer vision technologies in several
research directions. Specifically, with a group of several research scientists and PhD students, TeV
works at the intersection of machine perception, artificial intelligence, and robotics, developing vision
systems that interpret, reconstruct, and understand complex visual environments. Their research
spans a wide range of topics including 2D and 3D scene understanding, image and video analysis,
object detection, segmentation, tracking, and robotic perception [16]. Leveraging state-of-the-art
technologies such as deep learning, multimodal fusion, and large vision-language models, the unit
focuses on enabling machines to understand the world in ways that mirror human perception. An
important feature of TeV’s work is its comprehensive coverage of vision tasks across diferent domains
and modalities. The unit develops algorithms for zero-shot learning, neural rendering, Gaussian
splatting [17], optical flow estimation, visual odometry, and anomaly detection. Their expertise extends
to point cloud representation, scene reconstruction, Simultaneous Localization and Mapping, and 3D
semantic segmentation, enablers for spatial awareness in autonomous systems. They also contribute
to real-world applications including smart retail, food quality analysis, aerial imaging, microscopy,
and sports analytics. TeV’s contributions are frequently validated through impactful datasets, such
as those capturing drone imagery in natural environments or industrial scenarios, and through open
research on vision benchmarks. The unit has established a strong presence in the evolving field of
visionlanguage integration. Their recent work includes the development of systems capable of vocabulary-free
3D segmentation and natural language interaction with scenes, supporting advanced applications in
robotics [16], embodied AI [18], and assistive technologies. The group also explores emerging methods
in neural radiance fields and fast pose estimation models [ 17], facilitating more photorealistic and
computationally eficient spatial modeling. TeV maintains a dynamic approach to bridging theoretical
research with industrial relevance. By building generalizable and adaptive computer vision solutions,
TeV continues to drive progress in making machines see and understand the world with increasing
depth and nuance.</p>
        <p>Machine Translation The MT unit is dedicated to advancing automatic translation technologies
for both text and speech, enabling seamless multilingual communication and access to large-scale
spoken and written content. Its core activities focus on developing deep learning architectures and
methods adaptable to diverse contexts, domains, and applications that can serve the translation industry,
such as simultaneous speech translation [19] and subtitling [20]. These solutions leverage
cuttingedge technologies, including large language models and foundation models. The unit also conducts
research on the ethical and societal implications of translation technology, by designing evaluation
methods, resources, and studies involving human participants, with a focus on gender-inclusive [21] and
human-centered translation [22]. In addition, the research is dedicated to developing sustainable and
trustworthy approaches to automatic translation, including resource-eficient solutions and methods
for explainable AI. All models, code, and datasets developed by the unit are publicly released.</p>

      <title>3. Applications of AI</title>
      <p>The Digital Industry Center actively fosters collaborations with a diverse range of funding agencies,
strategic alliances, and industrial partners. These collaborations occur at the local, national, and
international levels and serve to accelerate innovation and amplify the Center’s impact. The projected
funding horizon currently extends to 2027, with support from a diverse portfolio of sources. These
include national programs such as PNRR, EDIH-SoE, European initiatives such as H2020-HEurope RIA
and IA, and Digital Europe initiatives such as EIT, KDT and TEF. An important part is directly funded
by industrial contracts, also under the sponsorship of the PAT LP VI.</p>
      <p>Railways The railway domain is in a profound transition stimulated by the introduction of digital
technologies. On the one hand, electromechanical interlocking systems should be replaced by their
digital counterpart; on the other hand, trains are increasingly reliant on automated digital control
systems and becoming autonomous. FBK is involved in studying research solutions to support this
transition by proposing novel software engineering methodologies and supporting tools that have been
applied in a series of research projects. Specifically, regarding interlocking systems, a methodology has
been developed in ACC, ACC-toolset, ACC-testing projects, whose objective has been to allow railway
experts to design and test interlocking systems using model-based software engineering approaches
and AI-based and formal reasoning techniques [23, 24]. The ATO projects aim at the design and testing
of the control system of an autonomous train for the inspections of the high-speed lines.
Aerospace The Center boasts a strong history of collaboration in the aerospace domain, with
numerous projects undertaken with the European Space Agency (ESA) through ESTEC and ESOC, as well as
the Italian Space Agency (ASI). Additionally, the Center has established a productive partnership with
Boeing. Current projects demonstrate a focus on integrative AI solutions for aerospace applications.
These include EXPLODTWIN, which integrates digital twins, AI, planning, and monitoring; VAIPOSA,
dedicated to verifiable AI-based Position, Navigation, and Timing (PNT); AIFDIR, focusing on integrated
symbolic and AI-based Fault Detection, Isolation, and Recovery (FDIR); and AISHGO, which explores
the application of AI for health monitoring.</p>
      <p>Manufacturing There are numerous applications of AI to manufacturing. First, product quality
control is based on vision and metrology techniques in sectors including the production of hollow glass,
tires, car components, electronic boards, and assembly of complex subsystems. Condition monitoring
and predictive maintenance are tackled in multiple projects, following an approach that integrates
symbolic models of the behavior of the equipment and its faults, data-driven techniques for time-series
analysis, and Edge AI. The application sectors include marine engines, of-highway vehicles, industrial
ovens, and drainage pumps. Adaptive process control and automated planning and optimization are
applied to sectors including electroplating, production of pharmaceutical principles and detergents,
recipe scheduling, energy production and storage.</p>
      <p>Weather AI for Weather and Climate at FBK focuses on developing AI models for accurate, timely
weather and climate information, addressing climate change challenges. The research focuses on three
key areas: nowcasting, downscaling, and seasonal forecasting. Nowcasting utilizes generative AI to
produce 0-6 hour precipitation forecasts from radar and observational data, enabling the prediction of
extreme events. Downscaling involves creating high-resolution data from low-resolution inputs, making
it suitable for seasonal and climate projections. Seasonal forecasting uses AI to identify temperature
and precipitation anomalies, starting with European patterns. These projects involve stakeholders such
as civil protection agencies for alerts, insurance firms assessing risk, and energy companies managing
resources and demand across various timeframes.</p>
      <p>Cultural Heritage In the cultural heritage sector the focus is on developing (i) advanced 3D
documentation solutions, (ii) 2D / 3D semantic enrichment processes, and (iii) speech and text translation
solutions to improve accessibility and broaden the reach of cultural heritage content. Within the
ongoing EU projects 3D-4CH, 3DBigDataSpace and XRCulture, FBK is contributing with large scale 3D
semantic reconstruction and machine translation technologies to widespread digital heritage usage and
accessibility.</p>
      <p>Digital Agriculture Digital technologies for agriculture represent an application domain of primary
interest for Italy and for research at FBK. Italy is facing the challenge of a more eficient agriculture, able
to improve the quality and value of products by improving environmental sustainability and enhancing
local identities to the maximum extent. The application of Artificial Intelligence to environmental and
climatic data, collected automatically in the field by machines, together with the company’s process
data, allows the development of solutions capable of promoting eficiency and productivity, improving
the yield and sustainability of agricultural practices. The Digital Industry Center applies artificial
intelligence using advanced expertise in IoT, Edge AI, computer vision, robotics, climate modeling, and
digital twins. The strategic initiative is structured around three core pillars: agricultural digital twins
for data-driven decision-making, contextual AI for real-time agronomic recommendations, and digital
infrastructures for data management and sharing. Various active projects (e.g., IRRITRE, AGRICLIMA,
AgrifoodTEF, and AgRimate) enable concrete applications in smart irrigation, climate resilience, and
agricultural robotics, strengthening sustainability, productivity, and food quality in the agrifood sector.</p>
