How to out-perform default random forest regression: choosing hyperparameters for applications in large-sample hydrology

Authors: Divya K. Bilolikar, Aishwarya More, Aella Gong, Joseph Janssen

arXiv

Predictions are a central part of water resources research. Historically, physically-based models have been preferred; however, they have largely failed at modeling hydrological processes at a catchme...

Bayesian feedback in the framework of ecological sciences

Authors: Mario Figueira-Pereira, Xavier Barber, David Conesa, Antonio LĂłpez-QuĂ­lez, JoaquĂ­n MartĂ­nez-Minaya, Iosu Paradinas, Maria Grazia Pennino

arXiv

In ecology we may find scenarios where the same phenomenon (species occurrence, species abundance, etc.) is observed using two different types of samplers. For instance, species data can be collected...

Deep Variational Lesion-Deficit Mapping

Authors: Guilherme Pombo, Robert Gray, Amy P. K. Nelson, Chris Foulon, John Ashburner, Parashkev Nachev

arXiv

Causal mapping of the functional organisation of the human brain requires evidence of \textit{necessity} available at adequate scale only from pathological lesions of natural origin. This demands infe...

Nonparametric Identification and Estimation of Earnings Dynamics using a Hidden Markov Model: Evidence from the PSID

Authors: Tong Zhou

arXiv

This paper presents a hidden Markov model designed to investigate the complex nature of earnings persistence. The proposed model assumes that the residuals of log-earnings consist of a persistent comp...

Quantum Brain Dynamics. A Possibility of Having a Quantum Interpretation of the Brain

Authors: Dozie Iwuh

arXiv

What Quantum Brain Dynamics (QBD) considers is not just these other functions of the brain, this is because they can be well analyzed with the workings of classical mechanics (even though they still p...

Central Limit Theorems and Approximation Theory: Part I

Authors: Arisina Banerjee, Arun K Kuchibhotla

arXiv

Central limit theorems (CLTs) have a long history in probability and statistics. They play a fundamental role in constructing valid statistical inference procedures. Over the last century, various tec...

Heterogeneity-aware integrative regression for ancestry-specific association studies

Authors: Aaron J. Molstad, Yanwei Cai, Alexander P. Reiner, Charles Kooperberg, Wei Sun, Li Hsu

arXiv

Ancestry-specific proteome-wide association studies (PWAS) based on genetically predicted protein expression can reveal complex disease etiology specific to certain ancestral groups. These studies req...

Spike timing reshapes robustness against attacks in spiking neural networks

Authors: Jianhao Ding, Zhaofei Yu, Tiejun Huang, Jian K. Liu

arXiv

The success of deep learning in the past decade is partially shrouded in the shadow of adversarial attacks. In contrast, the brain is far more robust at complex cognitive tasks. Utilizing the advantag...

Analysis of dynamic restricted mean survival time based on pseudo-observations

Authors: Zijing Yang, Chengfeng Zhang, Yawen Hou, Zheng Chen

arXiv

In clinical follow-up studies with a time-to-event end point, the difference in the restricted mean survival time (RMST) is a suitable substitute for the hazard ratio (HR). However, the RMST only meas...
