Experimenters today frequently quantify millions or even billions of characteristics (measurements) each sample to address critical biological issues, in the hopes that machine learning tools would be able to make correct data-driven judgments. An efficient analysis requires a low-dimensional representation that preserves the differentiating features in data whose size and complexity are orders of magnitude apart (e.g., if a certain ailment is present in the person's body). While there are several systems that can handle millions of variables and yet have strong empirical and conceptual guarantees, there are few that can be clearly understood. This research presents an evaluation of supervised dimensionality reduction for large scale data. We provide a methodology for expanding Principal Component Analysis (PCA) by including category moment estimations in low-dimensional projections. Linear Optimum Low-Rank (LOLR) projection, the cheapest variant, includes the class-conditional means. We show that LOLR projections and its extensions enhance representations of data for future classifications while retaining computing flexibility and reliability using both experimental and simulated data benchmark. When it comes to accuracy, LOLR prediction outperforms other modular linear dimension reduction methods that require much longer computation times on conventional computers. LOLR uses more than 150 million attributes in brain image processing datasets, and many genome sequencing datasets have more than half a million attributes.

Given the significance of national carbon inventories, the importance of large-scale estimates of carbon stocks is increasing. Accurate biomass estimates are essential for tracking changes in the carbon stock through repeated assessment of carbon stock, widely used for both vegetation and soil, to estimate carbon sequestration. Objectives: The aim of our study was to determine the variability of several aspects of the carbon stock value when the input matrix was (1) expressed either as a vector or as a raster; (2) expressed as in local (1:10,000) or regional (1:100,000) scale data; and (3) rasterized with different pixel sizes of 1, 10, 100, and 1000 m. Method: The look-up table method, where expert carbon content values are attached to the mapped landscape matrix. Results: Different formats of input matrix did not show fundamental differences with exceptions of the biggest raster of size 1000 m for the local level. At the regional level, no differences were notable. Conclusions: The results contribute to the specification of best practices for the evaluation of carbon storage as a mitigation measure, as well as the implementation of national carbon inventories.

Artificial intelligence (ARTINT) and information have been famous fields for many years. A reason has been that many different areas have been promoted quickly based on the ARTINT and information, and they have created many significant values for many years. These crucial values have certainly been used more and more for many economies of the countries in the world, other sciences, companies, organizations, etc. Many massive corporations, big organizations, etc. have been established rapidly because these economies have been developed in the strongest way. Unsurprisingly, lots of information and large-scale data sets have been created clearly from these corporations, organizations, etc. This has been the major challenges for many commercial applications, studies, etc. to process and store them successfully. To handle this problem, many algorithms have been proposed for processing these big data sets.

Introduction: In this COVID-19 pandemic, protective measures against the disease and government-imposed policies should be known. However, the media also report on deaths and health service shortages, but their impact on the mental health of the population is ignored.Objective: To determine whether fear of COVID-19 infection acts as a mediator between exposure to news about the pandemic and mental health in the Peruvian population.Method: Explanatory study with observable variables in which 541 persons selected by non-probabilistic sampling participated. They responded to a sociodemographic file and the following scales: Mental Health Inventory-5 (MHI-5) and Fear of COVID-19 Scale. Data were processed using IBM SPSS Statistics 25 and Macro PROCESS for SPSS programs; linear regression and bootstrapping of 10 000 simulations were used.Results: The number of hours watching and/or listening to covid-19 information is a good predictor of the COVID-19 fear mediator variable (β= ,75; t = 3.77, p<.001**). In turn, this has a predictor effect on mental health (β= -,24; t = -13.57, p<.001**). However, the number of hours of exposure to COVID-19 information had no direct positive effect on mental health (β= -.10; t = -1.184, p=.23).Conclusion: Fear of COVID-19 has a total mediating effect between exposure to pandemic news and mental health in the Peruvian population. Introducción: En esta pandemia por covid-19 se deben conocer las medidas de protección contra la enfermedad y las políticas impuestas por el gobierno; empero, los medios de comunicación también informan sobre las muertes y el desabastecimiento de los servicios de salud, pero se ignora su impacto en la salud mental de la población.Objetivo: Determinar si el miedo al contagio de la covid-19 actúa como mediador entre la exposición a las noticias sobre la pandemia y la salud mental en población peruana.Método: Estudio explicativo con variables observables, donde participaron 541 personas seleccionadas con un muestreo no probabilístico. Respondieron una ficha sociodemográfica y las escalas: Mental Health Inventory-5 (MHI-5) y Fear of Covid-19 Scale. Los datos fueron procesados mediante los programas IBM SPSS Statistics 25 y Macro PROCESS para SPSS; se utilizó la regresión lineal y bootstrapping de 10 000 simulaciones.Resultados: El número de horas viendo y/o escuchando información de la covid-19 es un buen predictor de la variable mediadora de miedo a la covid-19 (β= ,75; t = 3,77, p<,001**); a su vez, esta tiene un efecto predictor sobre la salud mental (β= -,24; t = -13,57, p<,001**); sin embargo, el número de horas de exposición a la información de la covid-19 no tuvo un efecto directo positivo en la salud mental (β= -,10; t = -1,184, p=,23).Conclusión: El miedo a la covid-19 tiene un efecto mediador total entre la exposición a las noticias sobre la pandemia y la salud mental en la población peruana.

The past decade has been characterized by the growing volumes of data due to the widespread use of the Internet of Things (IoT) applications, which introduced many challenges for efficient data storage and management. Thus, the efficient indexing and searching of large data collections is a very topical and urgent issue. Such solutions can provide users with valuable information about IoT data. However, efficient retrieval and management of such information in terms of index size and search time require optimization of indexing schemes which is rather difficult to implement. The purpose of this paper is to examine and review existing indexing techniques for large-scale data. A taxonomy of indexing techniques is proposed to enable researchers to understand and select the techniques that will serve as a basis for designing a new indexing scheme. The real-world applications of the existing indexing techniques in different areas, such as health, business, scientific experiments, and social networks, are presented. Open problems and research challenges, e.g., privacy and large-scale data mining, are also discussed.

The recent unprecedented success of deep learning (DL) in various fields is underlied by its use of large-scale data and models. Training a large-scale deep neural network (DNN) model with large-scale data, however, is time-consuming. To speed up the training of massive DNN models, data-parallel distributed training based on the parameter server (PS) has been widely applied. In general, a synchronous PS-based training suffers from the synchronization overhead, especially in heterogeneous environments. To reduce the synchronization overhead, asynchronous PS-based training employs the asynchronous communication between PS and workers so that PS processes the request of each worker independently without waiting. Despite the performance improvement of asynchronous training, however, it inevitably incurs the difference among the local models of workers, where such a difference among workers may cause slower model convergence. Fro addressing this problem, in this work, we propose a novel asynchronous PS-based training algorithm, SHAT that considers (1) the scale of distributed training and (2) the heterogeneity among workers for successfully reducing the difference among the local models of workers. The extensive empirical evaluation demonstrates that (1) the model trained by SHAT converges to the higher accuracy up to 5.22% than state-of-the-art algorithms, and (2) the model convergence of SHAT is robust under various heterogeneous environments.
