, 2013 Non-linear image reconstruction and signal analysis deal with complex inverse problems. To tackle such problems in a systematic way, I present information field theory (IFT) as a means of Bayesian, data based inference on spatially distributed signal ...

Iterative Processing for Superposition Mapping
Journal of Electrical and Computer Engineering, 2010 Superposition mapping (SM) is a modulation technique which loads bit tuples onto data symbols simply via linear superposition. Since the resulting data symbols are often Gaussian-like, SM has a good theoretical potential to approach the capacity of ...

A Tutorial for Information Theory in Neuroscience
eNeuro, 2018 Understanding how neural systems integrate, encode, and compute information is central to understanding brain function. Frequently, data from neuroscience experiments are multivariate, the interactions between the variables are nonlinear, and the ...

PyPhi: A toolbox for integrated information theory [PDF]
PLoS Comput. Biol., 2017 Integrated information theory provides a mathematical framework to fully characterize the cause-effect structure of a physical system. Here, we introduce PyPhi, a Python software package that implements this framework for causal analysis and unfolds the ...

Multiaccess Channels with State Known to One Encoder: Another Case of Degraded Message Sets
, 2009 We consider a two-user state-dependent multiaccess channel in which only one of the encoders is informed, non-causally, of the channel states. Two independent messages are transmitted: a common message transmitted by both the informed and uninformed ...

Information Theory based on Non-additive Information Content
, 2001 We generalize the Shannon's information theory in a nonadditive way by focusing on the source coding theorem. The nonadditive information content we adopted is consistent with the concept of the form invariance structure of the nonextensive entropy. Some

Fading in Reflective and Heavily Shadowed Industrial Environments With Large Antenna Arrays
IEEE Open Journal of Antennas and PropagationOne of the required communication solutions to support novel use cases, e.g., in industrial environments, for 5G systems and beyond is ultra-reliability low-latency communication (URLLC).

Rapid Material Appearance Acquisition Using Consumer Hardware
Sensors, 2014 A photo-realistic representation of material appearance can be achieved by means of bidirectional texture function (BTF) capturing a material’s appearance for varying illumination, viewing directions, and spatial pixel coordinates.

On the tuning of atmospheric inverse methods: comparisons with the European Tracer Experiment (ETEX) and Chernobyl datasets using the atmospheric transport model FLEXPART [PDF]
Geoscientific Model Development, 2020 Estimation of the temporal profile of an atmospheric release, also called the source term, is an important problem in environmental sciences. The problem can be formalized as a linear inverse problem wherein the unknown source term is optimized to ...

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada
Population Ecology, EarlyView.We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...
