A Novel Tree Model-based DNN to Achieve a High-Resolution DOA Estimation via Massive MIMO receive array

Posted by Caltech

Kavli Affiliate: Wei Gao | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: To satisfy the high-resolution requirements of direction-of-arrival (DOA) estimation, conventional deep neural network (DNN)-based methods using grid idea need to significantly increase the number of output classifications and also produce a huge high model complexity. To address this problem, a […]

Alignment is not sufficient to prevent large language models from generating harmful information: A psychoanalytic perspective

Posted by dbos Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Zi Yin, Wei Ding, Jia Liu, , | Summary: Large Language Models (LLMs) are central to a multitude of applications but struggle with significant risks, notably in generating harmful content and biases. Drawing an analogy to the human psyche’s conflict between evolutionary survival instincts and societal norm […]

Impact of half-wave plate systematics on the measurement of CMB $B$-mode polarization

Posted by dbos Tokyo

Kavli Affiliate: Tomotake Matsumura | First 5 Authors: Marta Monelli, Eiichiro Komatsu, Tommaso Ghigna, Tomotake Matsumura, Giampaolo Pisano | Summary: Polarization of the cosmic microwave background (CMB) can help probe the fundamental physics behind cosmic inflation via the measurement of primordial $B$ modes. As this requires exquisite control over instrumental systematics, some next-generation CMB experiments […]
