New diagnostic approaches to establish the severity of chronic heart failure as a widespread syndrome on a background of cardiovascular diseases should integrate the results of various studies of the pathogenesis and create a basis for risk assessment of its progression, estimation of the individual prognosis. To develop an algorithm of integrated assessment and prediction of functional disorders of the cardio-vascular system, a neural network analysis of echo- and Doppler-cardiography indicators, markers of subclinical inflammation, lipid disorders, oxidative stress, apoptosis, interstitial fibrosis in the myocardium, reflecting the severity of the major pathogenetic processes in the progression of heart failure in elderly hypertensive patients was carried out. The use of neural network analysis by means of neuro-imitator NeuroPro 0,25 on the basis of a consultation of neural networks has provided a highly accurate assessment of the risk of cardiovascular disorders. As results of the experiment were 15 neural networks of minimum structure with their simplification by reducing the number of input signals, allowed to accurately predict the functional class of heart failure. The highest factor importance of reducing serum levels of tissue inhibitor of matrix metalloproteinase-1 less than 500 pg/ml, the increasing end-diastolic dimensions of the left ventricle over 5 cm, the activity level of high-sensitivity C-reactive protein more than 5 mg/l in determining the prognosis of progression of chronic heart failure were identified

Recent research suggests that China’s Belt and Road Initiative (BRI) would improve the bilateral trade between China and its partners. This article uses detailed bilateral export data from 1990 to 2017 to investigate the impact of China’s BRI on its trade partners using neural network analysis techniques and structural gravity model estimations. Our main findings suggest that the BRI countries would raise exports by a modest 5.053%. This indicates that export and network upgrades should be considered from economic and policy perspectives. The results also show that neural networks is more robust compared with structural gravity framework.

The Belt And Road

The Belt and Road Initiative (BRI) under the auspices of the Chinese government was created as a regional integration and development model between China and her trade partners. Arguments have been raised as to whether this initiative will be beneficial to participating countries in the long run. We set to examine how to estimate this trade initiative by comparing the relative estimation powers of the traditional gravity model with the neural network analysis using detailed bilateral trade exports data from 1990 to 2017. The results show that neural networks are better than the gravity model approach in learning and clarifying international trade estimation. The neural networks with fixed country effects showed a more accurate estimation compared to a baseline model with country-year fixed effects, as in the OLS estimator and Poisson pseudo-maximum likelihood. On the other hand, the analysis indicated that more than 50% of the 6 participating East African countries in the BRI were able to attain their predicted targets. Kenya achieved an 80% (4 of 5) target. Drawing from the lessons of the BRI and the use of neural network model, it will serve as an important reference point by which other international trade interventions could be measured and compared.

This paper aims to predict the bankruptcy in Indian private banks using financial ratios such as ROA, GNPA, EPS, PAT, and GNP of the country. This paper also explains the importance of Ohlson’s number, Graham’s number and Zmijewski number as the major predictors of bankruptcy while developing a model using neural networks. For the prediction, the financial data for private sector banks of India such as HDFC, HDFC, ICICI, AXIS, YES bank, KOTAK MAHINDRA Bank, FEDERAL BANK, INDUSIND Bank, RBL and KARUR VYSYA for the last 10 years from 2010-2019 have been analysed. The model developed during the research will help the financial institutions and banks in India to understand the economic condition of the banking industry.

Uno de los problemas más graves que atraviesan las microempresas y empresas en nuestro país, es el referido al problema de los impagos en gestión de tesorería. Este artículo aborda las distintas acciones encaminadas al recobro de un impago mediante la utilización de teoría del expertizaje para alimentar una matriz de efectos olvidados que permita tomar decisiones  y sirva como  instrumento de diseño para representar la política de gestión de cada empresa en las distintas acciones a tomar, es el caso de estudio de los artesanos de calzado del cantón Gualaceo Provincial del Azuay, donde no existe una política adecuada de gestión empresarial para el recobro de impagos por parte de clientes de sus productos. Se indicará paso a paso un grafo representativo de estas políticas a ejecutar en los pagos atrasados por parte de clientes u otras organizaciones con la empresa de calzado, justificando cada arco mediante el uso del análisis de redes neuronales. Una vez conocido la existencia de los impagos se aplica el expertizaje para construir la matriz de convolución que permite descubrir las acciones que han sido olvidadas y que deberá atacar la gerencia para poder tener éxito en la recuperación de los recobros no procesados.Palabras clave: Calzado, expertizaje, impagos, lógica difusa, redes neuronales.  ABSTRACTOne of the most serious problems that the micro companies and companies cross in our country, is recounted to the problem of the non-payments in financiering. This article tackles the different actions directed to the recovery of a non-payment by means of the use of theory of the expertizaje to feed a counterfoil of forgotten effects that allows to take decisions and serves like design instrument to represent the politics of management of every company in the different actions to take, it is the case of study of the craftsmen of footwear of the canton Gualaceo Provincial of the Azuay, where a suitable politics of managerial management does not exist for the non-payments recovery on the part of clients of its products. A graph representative of this politics will be indicated step by step to execute in the payments slowed down on the part of clients or other organizations with the company of footwear, justifying every arch by means of the use of the neural network analysis. Once known the existence of the non-payments applies the expertizaje to itself to construct the counterfoil of convolución that allows to discover the actions that have been forgotten and that the management will have to attack to be able to be successful in the recovery of the not processed recoveries.Keywords: Footwear, expertizaje, non-payments, diffuse logic, neural networks.
