Research on stock trend prediction method based on optimized random forest

open access: yesCAAI Transactions on Intelligence Technology, 2023
As a complex hot problem in the financial field, stock trend forecasting uses a large amount of data and many related indicators; hence it is difficult to obtain sustainable and effective results only by relying on empirical analysis.

Forecasting the Dialysis Burden in Japan: Validation‐Based Projections of Prevalence and Incidence Through 2050

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.

Modeling a random search [PDF]

open access: yes, 1975
A model for random search is considered which differs from the classical random search by modeling the random paths of the searcher and/or target as those of a Wiener process.

LSTM: A Search Space Odyssey [PDF]

open access: yesIEEE Transactions on Neural Networks and Learning Systems, 2015
Several variants of the long short-term memory (LSTM) architecture for recurrent neural networks have been proposed since its inception in 1995. In recent years, these networks have become the state-of-the-art models for a variety of machine learning ...

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Accelerated Random Search for constrained global optimization assisted by Radial Basis Function surrogates

open access: yesJournal of Computational and Applied Mathematics, 2018
The Accelerated Random Search (ARS) algorithm (Appel et al., 2004) is a stochastic algorithm for the global optimization of black-box functions subject only to bound constraints. ARS iteratively samples uniformly within a box centered at the current best

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Machine Learning-Based Energy Consumption and Carbon Footprint Forecasting in Urban Rail Transit Systems

open access: yesApplied Sciences
In the fight against global climate change, the transportation sector is of critical importance because it is one of the major causes of total greenhouse gas emissions worldwide. Although urban rail transit systems offer a lower carbon footprint compared
