MBZUAI Professor Kun Zhang is developing machine learning techniques to identify hidden causal variables, which are underlying concepts driving cause-and-effect relationships. Zhang and colleagues from Carnegie Mellon University are presenting a new approach for this at ICML 2024. Their method, causal representation learning, assumes that measured variables are generated by unobserved latent variables. Why it matters: Uncovering hidden causal relationships can significantly advance understanding in various fields by revealing the underlying mechanisms driving observed phenomena.
MBZUAI researchers presented a new machine learning method at ICLR for uncovering hidden variables from observed data. The method, called "complementary gains," combines two weak assumptions to provide identifiability guarantees. This approach aims to recover true latent variables reflecting real-world processes, while solving problems efficiently. Why it matters: The research advances disentangled representation learning by finding minimal assumptions necessary for identifiability, improving the applicability of AI models to real-world data.
Researchers from MBZUAI presented a new algorithm at ICLR 2024 that identifies causal relationships involving both observed and latent variables. The algorithm addresses limitations of existing methods that struggle with latent variables or assume observed variables don't directly influence latent variables. The proposed algorithm can accommodate both scenarios, offering a more generalizable approach to causal discovery. Why it matters: This research advances the development of AI systems that can analyze complex data and identify causal relationships, with potential applications in fields like medicine where understanding causality is crucial for developing treatments and preventative measures.

MBZUAI researchers have developed a new kernel-based method to identify dependence patterns in data, especially in small regions exhibiting 'rare dependence' where relationships between variables differ. The method uses sample importance reweighting, assigning more importance to regions with rare dependence. Tested on synthetic and real-world data, the algorithm successfully identified relations between variables even with rare dependence, outperforming traditional methods like HSIC. Why it matters: This advancement can improve data analysis in fields like public health, economics, genomics, and AI, enabling more accurate insights from complex observational data.
Communications Physics journal has a focus collection on space quantum communications. The collection covers supporting technologies, new quantum protocols, inter-satellite QKD, constellations of satellites, and quantum inspired technologies and protocols for space based communication. Contributions are welcome from October 20, 2020 to April 30, 2021, and accepted papers are published on a rolling basis. Why it matters: Space-based quantum communication is a critical area for developing secure, global quantum networks, and this collection could highlight relevant research for the GCC region as it invests in advanced technologies.
MBZUAI researchers developed a new conditional independence test (DCT) that determines the dependence of two variables when both are discrete, continuous, or when one is discrete and the other is continuous. The new test addresses cases where variables are inherently continuous but represented in discretized form due to data collection limits. The findings will be presented at the 13th International Conference on Learning Representations (ICLR) in Singapore. Why it matters: This research addresses a fundamental problem in machine learning and statistics, improving causal relationship discovery in mixed datasets common across finance, public health, and other fields.
KAUST's Environmental Epigenetics Program (KEEP), led by Prof. Valerio Orlando, focuses on understanding how cells acquire and maintain memory, particularly in response to environmental factors. The research investigates the role of non-coding RNA and chromosomal components in regulating gene expression beyond the DNA sequence. Epigenetics explains how the same genome can be interpreted differently, allowing cells and organs to adapt to changing conditions. Why it matters: This research could provide insights into how environmental factors impact gene expression and cell function, potentially leading to advances in understanding and treating diseases.
