This study investigates methods to steer Arabic Large Language Models (LLMs) towards generating specific dialects, addressing the challenge of data scarcity for dialectal Arabic. Researchers identified sparse neuron populations encoding dialect-specific features and developed a vector-steering approach using dialect-specific activation directions. These inference-time methods allow for controlling dialectal output by amplifying or suppressing neuron activity or injecting specific vectors. Why it matters: This research offers a principled, interpretability-grounded framework to improve dialectal accuracy in Arabic LLMs without fine-tuning, crucial for enhancing their utility in the diverse Arabic-speaking world.
This paper presents a methodology for digitizing and encoding the Al-Mawrid Arabic-English dictionary using the ISO Lexical Markup Framework (LMF) and TEI Lex-0 guidelines. The research resolves structural ambiguities and inconsistencies, achieving a structural parsing accuracy of 91% and high precision/recall for information extraction, such as 85% precision for synonyms. It also discusses limitations of TEI Lex-0 for Arabic phenomena and explores Linguistic Linked Open Data (LLOD) integration. Why it matters: This work provides a crucial, standardized computational lexicon for Arabic, addressing a significant gap in Arabic lexical infrastructure and offering a reproducible workflow for retro-digitization efforts in Arabic NLP and Digital Humanities.
This paper presents a methodology for digitizing and encoding the Al-Mawrid Arabic-English dictionary, transforming it into a standardized computational lexicon using the ISO Lexical Markup Framework (LMF) and TEI Lex-0 guidelines. The research, based on an empirical analysis of the letter Ayn (4.6% of the dictionary), achieved a structural parsing accuracy of 91%. Quantitative evaluation showed high performance for information extraction rules, including 85% precision and 98% recall for synonyms. Why it matters: This work addresses a significant gap in Arabic lexical infrastructure, providing an interoperable, machine-tractable resource and a reproducible workflow for retro-digitizing complex legacy bilingual lexicons for Arabic NLP and Digital Humanities.
Abu Dhabi's Technology Innovation Institute (TII) has developed a new quantum optimization solver in collaboration with NVIDIA, Los Alamos National Laboratory, and Caltech. The solver addresses large-scale combinatorial optimization problems using a small number of qubits, encoding over 7000 variables with only 17 qubits. Published in Nature Communications, the research demonstrates a hybrid quantum-classical algorithm with a novel encoding scheme that maximizes the use of quantum resources. Why it matters: This advancement marks a significant step toward practical quantum computing applications in the UAE and beyond, particularly in solving complex optimization challenges across various sectors.
The inaugural ASPIRE Abu Dhabi Autonomous Racing League (A2RL) will take place on April 27th at the Yas Marina Circuit with 8 teams competing for a $2.25 million prize. Teams will use identical Dallara Super Formula SF23 cars autonomized by TII, relying on their coding and AI algorithms to race. The event will feature autonomous cars racing simultaneously and an AI vs Human race with former F1 driver Daniil Kvyat. Why it matters: This event highlights the UAE's commitment to advancing AI and autonomous systems, potentially establishing Abu Dhabi as a hub for autonomous vehicle innovation in extreme conditions.
A cryptanalysis team at the UAE's Cryptography Research Center (CRC) has set new records in computation by decrypting a McEliece ciphertext without the secret key at INRIA’s McEliece decoding challenge, taking first and second place. The record computation took about 31.4 days on a cluster using 256 CPU-cores. The team also achieved top ranks in decoding quasi-cyclic codes and ternary codes, used in post-quantum cryptography. Why it matters: This achievement demonstrates the UAE's growing capabilities in advanced cryptography research and its contributions to the global effort to develop quantum-resistant algorithms.
The paper introduces the Prism Hypothesis, which posits a correspondence between an encoder's feature spectrum and its functional role, with semantic encoders capturing low-frequency components and pixel encoders retaining high-frequency information. Based on this, the authors propose Unified Autoencoding (UAE), a model that harmonizes semantic structure and pixel details using a frequency-band modulator. Experiments on ImageNet and MS-COCO demonstrate that UAE effectively unifies semantic abstraction and pixel-level fidelity, achieving state-of-the-art performance.
The paper introduces MedNNS, a neural network search framework designed for medical imaging, addressing challenges in architecture selection and weight initialization. MedNNS constructs a meta-space encoding datasets and models based on their performance using a Supernetwork-based approach, expanding the model zoo size by 51x. The framework incorporates rank loss and Fréchet Inception Distance (FID) loss to capture inter-model and inter-dataset relationships, improving alignment in the meta-space and outperforming ImageNet pre-trained DL models and SOTA NAS methods.
