recommendations! Published in 2018 at "Cognition"

DOI: 10.1016/j.cognition.2018.08.018

Abstract: In everyday communication, speakers make errors and produce language in a noisy environment. Recent work suggests that comprehenders possess cognitive mechanisms for dealing with noise in the linguistic signal: a noisy-channel model. A key parameter… read more here.

DOI: 10.1080/00949655.2025.2516793

Abstract: Understanding causal mechanisms in complex systems requires methodologies capable of disentangling non-linear interactions across high-dimensional variables. While the Confounding Cascade Nonlinear Additive Noise Model (CCANM) coupled with variational autoencoders (VAEs) provides a foundation for latent… read more here.

DOI: 10.1088/1402-4896/ab9a70

Abstract: An analytical solution of the dynamical evolution of an intrinsic noise model of a V-type threelevel atom confined in a cavity having one-mode coherent field via multi-photon transitions is obtained. We investigate the effect of… read more here.

DOI: 10.1093/mnras/stad1406

Abstract: The detailed modelling of stellar oscillations is a powerful approach to characterising stars. However, poor treatment of systematics in theoretical models leads to misinterpretations of stars. Here we propose a more principled statistical treatment for… read more here.

DOI: 10.1109/jsac.2020.3036964

Abstract: Model-based method and data-based method are two basic approaches for the design of wireless communication systems. Model-based methods suffer from inaccurate modeling assumptions due to excessively complex environment. Recently, data-based methods have achieved remarkable performances… read more here.

DOI: 10.1109/lcomm.2023.3255209

Abstract: Instead of assuming the accurate noise model and transmit power, we address the received signal strength (RSS) localization problem under a more practical assumption that the exact noise model and transmit power are unavailable. In… read more here.

DOI: 10.1121/1.4987429

Abstract: Surface processes, including non-linear surface wave interactions and bubble oscillations, dominate the deep water ambient noise in the absence of shipping and wildlife. A single-parameter noise model, determined by the wind speed above the ocean… read more here.
