A Caltech researcher presented at MBZUAI on memory representation and retrieval, contrasting AI and neuroscience approaches. Current AI retrieval systems like RAG retrieve via fine-tuning and embedding similarity, while the presenter argued for exploring retrieval via combinatorial object identity or spatial proximity. The research explores circuit-level retrieval via domain fine-tuned LLMs and distributed memory for image retrieval using semantic similarity. Why it matters: The work suggests structured databases and retrieval-focused training can allow smaller models to outperform larger general-purpose models, offering efficiency gains for AI development in the region.
MBZUAI's Metaverse Lab is developing AI algorithms for photorealistic virtual humans and dynamic environments. Hao Li, Director of the lab, envisions using the metaverse for immersive learning experiences related to history and culture. He is also working on tools to prevent deepfakes and other cyberthreats. Why it matters: This research at MBZUAI aims to advance AI and immersive technologies for education and address potential risks in the metaverse.
Prof. Simon Gröblacher from Delft University of Technology presented a seminar on using mechanical systems in quantum information processing, focusing on their potential as quantum memories and transducers. The seminar highlighted experiments demonstrating non-classical behavior of mechanical motion by coupling a micro-fabricated acoustic resonator to single optical photons. Quantum control over acoustic motion was established, including the generation and readout of single phononic excitations, along with light-matter entanglement. Why it matters: This research advances the use of micro-fabricated acoustic resonators for quantum information processing and fundamental tests of quantum physics.
A KAUST team developed piRNAi, a gene-silencing tool in nematode worms using synthetic RNA sequences interacting with the piRNA pathway. They successfully silenced genes involved in sex determination and other functions, demonstrating multiplexed gene silencing. The gene silencing lasted for varying durations across generations, up to six generations. Why it matters: This expands the molecular toolkit for gene manipulation and offers potential therapeutic applications in humans, given the presence of the same gene-silencing pathway.
Researchers from KAUST, University of St. Andrews, and the Center for Unconventional Processes of Sciences have developed an uncrackable security system using optical chips. The system uses silicon chips with complex structures that are irreversibly changed to send information, achieving "perfect secrecy" through a one-time key. This method leverages classical physics and the second law of thermodynamics to ensure that keys are never stored, communicated, or recreated, making interception impossible. Why it matters: This breakthrough has the potential to revolutionize communications privacy globally, offering an unbreakable method for securing confidential data on public channels.
MBZUAI's Dr. Hao Li is working on using AI and 3D telepresence to transform communication, work, and education by replacing physical transportation with virtual teleportation. His research focuses on the intersection of computer graphics, computer vision, and AI, specifically virtual avatar creation and facial performance capture. Li aims to improve communication using AI to achieve what cannot be done in real life. Why it matters: This research has the potential to reduce carbon footprints by enabling remote work and virtual collaboration, while also positioning MBZUAI and the UAE as leaders in AI-driven metaverse technologies.
KAUST researchers in the Sensors Lab are developing neuromorphic circuits for vision sensors, drawing inspiration from the human eye. They created flexible photoreceptors using hybrid perovskite materials, with capacitance tunable by light stimulation, mimicking the human retina. The team collaborates with experts in image characterization and brain pattern recognition to connect the 'eye' to the 'brain' for object identification. Why it matters: This biomimetic approach promises advancements in AI, machine learning, and smart city development within the region.
KAUST Discovery student Leen Al-Jefri presented a poster on broadband digital holographic memories. Another KAUST student, Aljazzy Alahmadi, worked with Professor Omar Abdulsaboor on charge career dynamics between perovskite nanocrystals and molecular acceptors. The work highlights opportunities for gifted Saudi students at KAUST. Why it matters: Developing local talent in advanced STEM fields is crucial for Saudi Arabia's Vision 2030 goals.
