When Less Is More: Systematic Analysis of Cascade-Based Community Detection [article]

Liudmila Prokhorenkova, Alexey Tikhonov, Nelly Litvak
2022 arXiv   pre-print
We also show that some well-known community detection algorithms can be enhanced by including edge weights based on the cascade data.  ...  This article conducts a systematic and extensive analysis of the following problem: Given only the infection times, find communities of highly interconnected nodes.  ...  A recent work [62] addressed a follow-up problem of cascade-based community detection when the cascade data are incomplete.  ...

When Less Is More $\ldots$ Few Bit ADCs in RF Systems

Christopher T. Rodenbeck, Matthew M. Martinez, Joshua B. Beun, Jose Silva-Martinez, Aydin Llker Karsilayan, Robert Liechty
2019 IEEE Access  
The diversity of established applications based on few bit ADCs, together with the recent surge of interest in the topic for 5G wireless communications and millimeter-wave radar, has created a need for  ...  Parametric analysis, independent of sampling considerations and system-specific signal processing, is used to illustrate the variation in the ADC output signal-to-noise-and-distortion ratio (SNDR) versus  ...  The spectral density estimate is limited by the processing gain of the FFT and is unable to resolve IM3 less than −60 dB when input SNR is low.  ...

A cross-ecosystem approach would therefore be valuable for a more thorough understanding of ecosystem responses to various stressors in the face of rapid environmental change.  ...  Aquatic and terrestrial organisms use cross-system subsidies to a comparable extent and addressing reciprocal subsidies is therefore necessary in order to understand biodiversity and functioning of both  ...  catchments may be more appropriate and more feasible for predicting aquatic biodiversity than measuring snapshot productivity based on water samples.  ...

Attention is more than prediction precision

Howard Bowman, Marco Filetti, Brad Wyble, Christian Olivers
2013 Behavioral and Brain Sciences  
AbstractA cornerstone of the target article is that, in a predictive coding framework, attention can be modelled by weighting prediction error with a measure of precision.  ...  We argue that this is not a complete explanation, especially in the light of ERP (event-related potentials) data showing large evoked responses for frequently presented target stimuli, which thus are predicted  ...  In cases where the theory is about the choice of a benchmark or a standard, more facts can only make a theory either more or less warranted.  ...

Integration of omics: more than the sum of its parts

2016 Cancer & Metabolism  
The cellular components from which these -omics regimes are derived act as one integrated system in vivo; thus, there is a natural instinct to integrate -omics data types.  ...  Statistical analyses, the use of previous knowledge in the form of networks, and the use of time-resolved measurements are three key design elements for life scientists to consider in planning integrated  ...  The systematic, statistical analysis of data generated for the same model system is greatly facilitated by the development of shared experimental material such as the NCI60 panel of cancer cell lines  ...
