In recent years, various time series models have been proposed for financial markets forecasting. In each case, the accuracy of time series forecasting models are fundamental to make decision and hence the research for improving the effectiveness of forecasting models have been curried on. Many researchers have compared different time series models together in order to determine more efficient ...

This paper introduces a pruning algorithm with tridiagonal symmetry constraints for feedforward neural network design. The algorithm uses a reeection transform applied to the input{hidden weight matrix in order to reduce it to its tridiagonal form. The designed FANN structures obtained by applying the proposed algorithm are compact and symmetrical. Therefore, they are well suited for eecient ha...

In this paper, extensive study of ring-opening polymerization ε-caprolactone (ε-CL) using lipase Novozym 435 as catalyst in flask level and reactor level were conducted. The polymerization rates increase with an increase in time up to 4 h after which there has been a steep decrease for all temperature from 50 to 100 °C in the flask level. The conclusion out of flask level and reactor level stud...

This thesis tests if certain technology choices are associated with a reduction in the proportion of farming activities in the agro-food system in Maine. Goodman, Sorj, and Wilkinson define appropriationism as the replacement of farming sector activities by industrial inputs. Based on the concept of appropriationism, industrial fanning systems using large amounts of synthetic inputs contribute ...

11–42% of general medical in-patients, with even higher rates in older patients, those with pre-existing cognitive impairment, terminal illness or receiving care in intensive care units. Although delirium is classically described as a syndrome with high inherent reversibility, studies have increasingly highlighted that persistence is a common occurrence in older people. Despite its relatively h...

In this study, we propose an advanced category of a fuzzy adaptive neural network (FANN) based on feature self-enhancement unit (FSU) and statistical selection methods (SSMs). Undoubtedly, the raw data contain large amount information with varying importance. One most important tasks for regression model design is to avoid losing these details. However, cannot participate in whole training proc...

Most mango farms classify the maturity stage manually by trained workers using external indicators such as size, shape, and skin color, which can lead to human error or inconsistencies. We developed four common machine learning (ML) classifiers, k-mean, naïve Bayes, support vector machine, feed-forward artificial neural network (FANN), all of were aimed at classifying ripeness mangoes harvest. ...
