Why it matters: As speech-based interfaces become more prevalent in the Middle East, understanding and addressing the associated privacy risks is crucial for ethical AI development and deployment.
Caltech graduate student Surya Narayanan Hari presented his research on replicating human-like memory in machines at MBZUAI. He discussed how the thalamus, which filters sensory and motor signals in the brain, inspires the development of routed monolithic models in AI. Hari explained that memory retrieval occurs on object, embedding, and circuit levels in the human brain. Why it matters: This talk highlights the potential of neuroscience-inspired AI architectures for improving memory and information processing in AI systems, which could accelerate the development of more efficient and context-aware AI models in the region.
NYU Abu Dhabi hosted a talk by Prof. Debdeep Mukhopadhyay on the intersection of machine learning and hardware security. The talk covered using ML/DL for side-channel attacks, leakage assessment in crypto-devices, and threats to hardware security primitives. Prof. Mukhopadhyay is a visiting professor at NYU Abu Dhabi and Institute Chair Professor at IIT Kharagpur. Why it matters: The talk highlights the growing importance of hardware security in modern systems and the role of machine learning in both attacking and defending hardware vulnerabilities.
Zeerak Talat, an independent scholar, gave a talk at MBZUAI on automated content moderation and the impacts of machine learning on society. Talat's research considers how machine learning interacts with and impacts societies through content moderation technologies, drawing from NLP, privacy preserving machine learning, science and technology studies, decolonize studies, and media studies. The talk highlighted research areas that can afford productive directions for the meeting between machine learning and society. Why it matters: The talk contributes to the discussion of ethical AI development and deployment in the region, particularly regarding content moderation and its societal impacts.
Dr. Zeke Xie from HKUST(GZ) presented research on noise initialization and sampling strategies for diffusion models. The talk covered golden noise for text-to-image models, zigzag diffusion sampling, smooth initializations for video diffusion, and leveraging image diffusion for video synthesis. Xie leads the xLeaF Lab, focusing on optimization, inference, and generative AI, with previous experience at Baidu Research. Why it matters: The work addresses core challenges in improving the quality and diversity of generated content from diffusion models, a key area of advancement for AI applications in the region.
Pong C Yuen from Hong Kong Baptist University will present a talk on remote photoplethysmography (rPPG) detection. The talk will review the development of rPPG detection, share recent research, and discuss future directions. rPPG is a technology for non-contact computer vision and healthcare applications like heart rate estimation. Why it matters: Advancements in rPPG could enable new remote patient monitoring and diagnostic tools in the region, reducing the need for physical contact.
Dr. Munawar Hayat from Monash University gave a talk on the history of AI, recent breakthroughs in deep learning, and future research directions. The talk covered computer vision, NLP, autonomous driving, and reinforcement learning. Dr. Hayat also discussed the limitations of AI and challenges in the field. Why it matters: This lecture helps contextualize the rapid progress of AI for students in the region.
Ekaterina Vylomova from the University of Melbourne gave a talk on using NLP models to advance research in linguistic morphology, typology, and social psychology. The talk covered using models to study morphology, phonetic changes in words over time, and diachronic changes in language semantics. Vylomova presented the UniMorph project, a cross-lingual annotation schema and database with morphological paradigms for over 150 languages. Why it matters: This research demonstrates the potential of NLP to contribute to a deeper understanding of language evolution and structure, with applications in linguistic research and the study of social and cultural changes.
