AutoML‐Multiverse: Model Agnostic Framework for Optimizing Individual‐level Alzheimer's Disease Classification [PDF]
Alzheimers DementAbstract Background Machine learning (ML) methods are widely used to develop predictive models for Alzheimer's disease (AD) stage classification, crucial for patient stratification in clinical trials. While the goals of these models are clear, the analytic processing and modelling details are not, causing conflicting results, and limiting clinical ...

Journal of High Energy Physics, 2021 We propose a new scenario of nonequilibirum multiverse. We quantified the potential landscape and the flux landscape for the multiverse. The potential landscape quantifies the weight of each universe. When the terminal vacuum with zero (flat) or negative

Automated and Unbiased Machine Learning Predictions of Alzheimer’s Risk Factors in an Ethnically Diverse Dataset using Cortical Thicknesses [PDF]
Alzheimers DementAbstract Background The 2024 Lancet Commission identified 14 major risk factors contributing to 45% of dementia cases globally. Many relate to brain structure changes, potentially mediating brain health on the pathway to dementia. This study explores these factors using brain imaging measures in binary prediction tasks.

Multiverse Assumptions and Philosophy [PDF]
Философия и космология, 2018 Multiverses are predictions based on theories. Focusing on each theory’s assumptions is key to evaluating a proposed multiverse. Although accepted theories of particle physics and cosmology contain non-intuitive features, multiverse theories entertain a ...

The Skeptical Challenge of the Theistic Multiverse
Ergo, An Open Access Journal of Philosophy, 2023 The multiverse theodicy says that because God can without cost create an infinite number of universes, the standards of acceptability that a conceivable universe must meet to be worthy of divine creation are significantly laxer than is typically supposed

Journal of High Energy Physics, 2021 We consider multiverse models in two-dimensional linear dilaton-gravity theories as toy models of false vacuum eternal inflation. Coupling conformal matter we calculate the Von Neumann entropy of subregions. When these are sufficiently large we find that

Model of a multiverse providing the dark energy of our universe [PDF]
, 2017 It is shown that the dark energy presently observed in our universe can be regarded as the energy of a scalar field driving an inflation-like expansion of a multiverse with ours being a subuniverse among other parallel universes.

Quantum state of the multiverse [PDF]
, 2011 A third quantization formalism is applied to a simplified multiverse scenario. A well defined quantum state of the multiverse is obtained which agrees with standard boundary condition proposals.

The Multiverse and Divine Creation
Religions, 2017 I provide the account of divine creation found in multiverse theorists Donald Turner, Klaas Kraay, and Tim O’Connor. I show that the accounts Kraay and Turner offer are incoherent.

A graceful multiversal link of particle physics to cosmology [PDF]
, 2007 In this paper we work out a multiverse scenario whose physical characteristics enable us to advance the following the conjecture that whereas the physics of particles and fields is confined to live in the realm of the whole multiverse formed by finite ...
