The kernel mutual information [PDF]
2003 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2003. Proceedings. (ICASSP '03)., 2004 We introduce a new contrast function, the kernel mutual information (KMI), to measure the degree of independence of continuous random variables. This contrast function provides an approximate upper bound on the mutual information, as measured near independence, and is based on a kernel density estimate of the mutual information between a discretised ...

Hashing with Mutual Information [PDF]
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2019 Binary vector embeddings enable fast nearest neighbor retrieval in large databases of high-dimensional objects, and play an important role in many practical applications, such as image and video retrieval. We study the problem of learning binary vector embeddings under a supervised setting, also known as hashing.

Achievable information rate optimization in C-band optical fiber communication system
Frontiers of Optoelectronics, 2023 Optical fiber communication networks play an important role in the global telecommunication network. However, nonlinear effects in the optical fiber and transceiver noise greatly limit the performance of fiber communication systems.

Distribution of mutual information [PDF]
Physics Letters A, 2001 In the analysis of time series from nonlinear sources, mutual information (MI) is used as a nonlinear statistical criterion for the selection of an appropriate time delay in time delay reconstruction of the state space. MI is a statistic over the sets of sequences associated with the dynamical source, and we examine here the distribution of MI, thus ...

Mutual Information between Order Book Layers
Entropy, 2022 The order book is a list of all current buy or sell orders for a given financial security. The rise of electronic stock exchanges introduced a debate about the relevance of the information it encapsulates of the activity of traders.

DEM REGISTRATION BASED ON MUTUAL INFORMATION [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012 The registration process forms an important step in the integration of Digital Elevation Models (DEMs) of resolution. DEM registration invariably involves what is effectively an 'image matching' process utilising similarity number of prospective image ...

Mutual Information, Fisher Information, and Population Coding [PDF]
Neural Computation, 1998 In the context of parameter estimation and model selection, it is only quite recently that a direct link between the Fisher information and information-theoretic quantities has been exhibited. We give an interpretation of this link within the standard framework of information theory.

Uncertainty Relation for Mutual Information [PDF]
, 2014 We postulate the existence of a universal uncertainty relation between the quantum and classical mutual informations between pairs of quantum systems. Specifically, we propose that the sum of the classical mutual information, determined by two mutually ...

Mutual information superadditivity and unitarity bounds
Journal of High Energy Physics, 2021 We derive the property of strong superadditivity of mutual information arising from the Markov property of the vacuum state in a conformal field theory and strong subadditivity of entanglement entropy. We show this inequality encodes unitarity bounds for

Estimating Information Processing of Human Fast Continuous Tapping from Trajectories
Entropy, 2022 Fitts studied the problem of information capacity and transfer in the speed–accuracy motor paradigm using a theoretical approach developed from Shannon and Weaver’s information theory.
