Robustifying Independent Component Analysis by Adjusting for Group-Wise Stationary Noise

Authors: Niklas Pfister, Sebastian Weichwald, Peter Bühlmann, Bernhard Schölkopf

arXiv

We introduce coroICA, confounding-robust independent component analysis, a novel ICA algorithm which decomposes linearly mixed multivariate observations into independent components that are corrupted...

tmleCommunity: A R Package Implementing Target Maximum Likelihood Estimation for Community-level Data

Authors: Chi Zhang, Jennifer Ahern, Mark J. van der Laan, Oleg Sofrygin

arXiv

Over the past years, many applications aim to assess the causal effect of treatments assigned at the community level, while data are still collected at the individual level among individuals of the co...

Supervised Visualization for Data Exploration

Authors: Jake S. Rhodes, Adele Cutler, Guy Wolf, Kevin R. Moon

arXiv

Dimensionality reduction is often used as an initial step in data exploration, either as preprocessing for classification or regression or for visualization. Most dimensionality reduction techniques t...

A Stochastic Biomass Blending Problem in Decentralized Supply Chains

Authors: Sandra D. Eksioglu, Berkay Gulcan, Mohammad Roni, Scott Mason

arXiv

Blending biomass materials of different physical or chemical properties provides an opportunity to adjust the quality of the feedstock to meet the specifications of the conversion platform. We propose...

Modeling tau transport in the axon initial segment

Authors: Ivan A. Kuznetsov, Andrey V. Kuznetsov

arXiv

By assuming that tau protein can be in seven kinetic states, we developed a model of tau protein transport in the axon and in the axon initial segment (AIS). Two separate sets of kinetic constants wer...

On the derivation of the renewal equation from an age-dependent branching process: an epidemic modelling perspective

Authors: Swapnil Mishra, Tresnia Berah, Thomas A. Mellan, H. Juliette T. Unwin, Michaela A Vollmer, Kris V Parag, Axel Gandy, Seth Flaxman, Samir Bhatt

arXiv

Renewal processes are a popular approach used in modelling infectious disease outbreaks. In a renewal process, previous infections give rise to future infections. However, while this formulation seems...

The COVID-19 pandemic's impact on U.S. electricity demand and supply: an early view from the data

Authors: Duzgun Agdas, Prabir Barooah

arXiv

After the onset of the recent COVID-19 pandemic, a number of studies reported on possible changes in electricity consumption trends. The overall theme of these reports was that ``electricity use has d...

Beyond accuracy: quantifying trial-by-trial behaviour of CNNs and humans by measuring error consistency

Authors: Robert Geirhos, Kristof Meding, Felix A. Wichmann

arXiv

A central problem in cognitive science and behavioural neuroscience as well as in machine learning and artificial intelligence research is to ascertain whether two or more decision makers (be they bra...

Structural diverseness of neurons between brain areas and between cases

Authors: Ryuta Mizutani, Rino Saiga, Yoshiro Yamamoto, Masayuki Uesugi, Akihisa Takeuchi, Kentaro Uesugi, Yasuko Terada, Yoshio Suzuki, Vincent De Andrade, Francesco De Carlo, Susumu Takekoshi, Chie Inomoto, Naoya Nakamura, Youta Torii, Itaru Kushima, Shuji Iritani, Norio Ozaki, Kenichi Oshima, Masanari Itokawa, Makoto Arai

arXiv

The cerebral cortex is composed of multiple cortical areas that exert a wide variety of brain functions. Although human brain neurons are genetically and areally mosaic, the three-dimensional structur...

Kernelized information bottleneck leads to biologically plausible 3-factor Hebbian learning in deep networks

Authors: Roman Pogodin, Peter E. Latham

arXiv

The state-of-the art machine learning approach to training deep neural networks, backpropagation, is implausible for real neural networks: neurons need to know their outgoing weights; training alterna...

From biophysical to integrate-and-fire modelling

Authors: Tomas Van Pottelbergh, Guillaume Drion, Rodolphe Sepulchre

arXiv

This paper proposes a methodology to extract a low-dimensional integrate-and-fire model from an arbitrarily detailed single-compartment biophysical model. The method aims at relating the modulation of...

Demixed shared component analysis of neural population data from multiple brain areas

Authors: Yu Takagi, Steven W. Kennerley, Jun-ichiro Hirayama, Laurence T. Hunt

arXiv

Recent advances in neuroscience data acquisition allow for the simultaneous recording of large populations of neurons across multiple brain areas while subjects perform complex cognitive tasks. Interp...

On parametric tests of relativity with false degrees of freedom

Authors: Alvin J. K. Chua, Michele Vallisneri

arXiv

General relativity can be tested by comparing the binary-inspiral signals found in LIGO--Virgo data against waveform models that are augmented with artificial degrees of freedom. This approach suffers...

NodeNet: A Graph Regularised Neural Network for Node Classification

Authors: Shrey Dabhi, Manojkumar Parmar

arXiv

Real-world events exhibit a high degree of interdependence and connections, and hence data points generated also inherit the linkages. However, the majority of AI/ML techniques leave out the linkages...

The multivariate tail-inflated normal distribution and its application in finance

Authors: Antonio Punzo, Luca Bagnato

arXiv

This paper introduces the multivariate tail-inflated normal (MTIN) distribution, an elliptical heavy-tails generalization of the multivariate normal (MN). The MTIN belongs to the family of MN scale mi...
