R&I group

Distributed AI

The Distributed Artificial Intelligence (DAI) research group conducts research and innovation activities in explainable and distributed AI, multimodal AI perception, and cognitive cloud. The group has a long track record of participation in EU R&D projects, Catalan and Spanish-funded research and innovation projects, and bilateral collaborations with private industry and the public sector. The research group develops and continuously updates a research roadmap to steer its activities and identify new fields to explore. One of the key added values of the DAI research group is its mission to boost the overall capabilities of i2CAT in AI, fostering synergies with the centre’s other research groups.

Research lines

Trustworthy AI
- Human Centric AI: Explainable and GenAI
- Decentralized Collaborative AI
- Quantum AI

The “Trustworthy AI” research line focuses on developing AI systems that are reliable, ethical, and sustainable. This includes Human-Centric AI, emphasizing Explainable AI and responsible Generative AI . We also explore Decentralized AI for secure and scalable distributed systems. Furthermore, we delve into Quantum AI, investigating how quantum computing can enable high-dimensional and efficient AI algorithms.

Multimodal AI-Perception
- Computational Vision and Scene Analysis
- NLP – Acoustic AI
- Volumetric Synthesis
Distributed Data Architectures
- AI-based DDA optimizations
- Data efficiency and privacy optimizations

In this research line we focus on complementing our AI technologies with cutting edge research on Distributed Data Architectures and optimizations. We specifically work on novel AI-centric data efficiency and privacy optimizations, such as data anonymization, aggregation and compression. We also delve into AI-based data optimizations, particularly for distributed data lake and edge-cloud management systems.
