چکیده
This study describes crash causes, conditions, and distribution of accident hot spots along with an analysis the risk factors that significantly affect severity levels crashes their effects on pedestrian safety using machine learning (ML) techniques. Supervised ML algorithm–random forest decision tree–based algorithm-AdaBoost algorithms are applied compared to predict level future based road elements. Association rule, unsupervised algorithm, is utilized understand association between driver characteristics, geometric elements highway, environment, time, weather, speed. Slight, medium, severe injuries fatalities in also considered behavior drivers, who most likely cause crashes. Fatalities studied spatial statistics analysis. The variables affecting determined discussed detail. results checked for accuracy, sensitivity, specificity, recall, precision, F1 score performance. impact vehicles, characteristics investigated traffic random model was found be suitable algorithm levels.

with the growth of more humanistic approaches towards teaching foreign languages, more emphasis has been put on learners’ feelings, emotions and individual differences. one of the issues in teaching and learning english as a foreign language is demotivation. the purpose of this study was to investigate the relationship between the components of language learning strategies, optimism, duration o...
15 صفحه اولSimple Models for Estimating Dementia Severity Using Machine Learning
Estimating dementia severity using the Clinical Dementia Rating (CDR) Scale is a two-stage process that currently is costly and impractical in community settings, and at best has an interrater reliability of 80%. Because staging of dementia severity is economically and clinically important, we used Machine Learning (ML) algorithms with an Electronic Medical Record (EMR) to identify simpler mode...
