Markovian And Non-Markovian Processes with Active Decision Making Strategies For Addressing The COVID-19 Pandemic

Authors: Hamid Eftekhari, Debarghya Mukherjee, Moulinath Banerjee, Ya'acov Ritov

arXiv

We study and predict the evolution of Covid-19 in six US states from the period May 1 through August 31 using a discrete compartment-based model and prescribe active intervention policies, like lockdo...

Uncovering the structure of clinical EEG signals with self-supervised learning

Authors: Hubert Banville, Omar Chehab, Aapo Hyvärinen, Denis-Alexander Engemann, Alexandre Gramfort

arXiv

Objective. Supervised learning paradigms are often limited by the amount of labeled data that is available. This phenomenon is particularly problematic in clinically-relevant data, such as electroence...

Sequential Drift Detection in Deep Learning Classifiers

Authors: Samuel Ackerman, Parijat Dube, Eitan Farchi

arXiv

We utilize neural network embeddings to detect data drift by formulating the drift detection within an appropriate sequential decision framework. This enables control of the false alarm rate although...

A superconducting nanowire spiking element for neural networks

Authors: Emily Toomey, Ken Segall, Matteo Castellani, Marco Colangelo, Nancy Lynch, Karl K. Berggren

arXiv

As the limits of traditional von Neumann computing come into view, the brain's ability to communicate vast quantities of information using low-power spikes has become an increasing source of inspirati...

Detecting bearish and bullish markets in financial time series using hierarchical hidden Markov models

Authors: Lennart Oelschläger, Timo Adam

arXiv

Financial markets exhibit alternating periods of rising and falling prices. Stock traders seeking to make profitable investment decisions have to account for those trends, where the goal is to accurat...

Analyzing Cause-Specific Mortality Trends using Compositional Functional Data Analysis

Authors: Marco Stefanucci, Stefano Mazzuco

arXiv

We study the dynamics of cause--specific mortality rates among countries by considering them as compositions of functions. We develop a novel framework for such data structure, with particular attenti...

Causal inference methods for small non-randomized studies: Methods and an application in COVID-19

Authors: Sarah Friedrich, Tim Friede

arXiv

The usual development cycles are too slow for the development of vaccines, diagnostics and treatments in pandemics such as the ongoing SARS-CoV-2 pandemic. Given the pressure in such a situation, ther...

Do not forget interaction: Predicting fatality of COVID-19 patients using logistic regression

Authors: Feng Zhou, Tao Chen, Baiying Lei

arXiv

Amid the ongoing COVID-19 pandemic, whether COVID-19 patients with high risks can be recovered or not depends, to a large extent, on how early they will be treated appropriately before irreversible co...

Conscious Intelligence Requires Lifelong Autonomous Programming For General Purposes

Authors: Juyang Weng

arXiv

Universal Turing Machines [29, 10, 18] are well known in computer science but they are about manual programming for general purposes. Although human children perform conscious learning (i.e., learning...

Normalized Connectomes Show Increased Synchronizability with Age Through Their Second Largest Eigenvalue

Authors: Wilten Nicola, Sue Ann Campbell

arXiv

The synchronization of different brain regions is widely observed under both normal and pathological conditions such as epilepsy. However, the relationship between the dynamics of these brain regions,...

Efficiency of learning vs. processing: Towards a normative theory of multitasking

Authors: Yotam Sagiv, Sebastian Musslick, Yael Niv, Jonathan D. Cohen

arXiv

A striking limitation of human cognition is our inability to execute some tasks simultaneously. Recent work suggests that such limitations can arise from a fundamental tradeoff in network architecture...

A Topological Approach to Inferring the Intrinsic Dimension of Convex Sensing Data

Authors: Min-Chun Wu, Vladimir Itskov

arXiv

We consider a common measurement paradigm, where an unknown subset of an affine space is measured by unknown continuous quasi-convex functions. Given the measurement data, can one determine the dimens...

Innovative And Additive Outlier Robust Kalman Filtering With A Robust Particle Filter

Authors: Alexander T. M. Fisch, Idris A. Eckley, P. Fearnhead

arXiv

In this paper, we propose CE-BASS, a particle mixture Kalman filter which is robust to both innovative and additive outliers, and able to fully capture multi-modality in the distribution of the hidden...

Amperometric Measurements and Dynamic Models Reveal a Mechanism for How Zinc Alters Neurotransmitter Release

Authors: Lin Ren, Alexander Oleinick, Irina Svir, Christian Amatore, Andrew Ewing

arXiv

Zinc, a suspected potentiator of learning and memory, is shown to affect exocytotic release and storage in neurotransmitter-containing vesicles. Structural and size analysis of the vesicular dense cor...
