Population explosion and the need to provide food for humankind and to increase the quality and quantity of food products in order to ensure food security with regard to its managerial, environmental, and developmental aspects has led to the use of new agriculture methods and technologies. Today, different approaches, such as plant breeding, genetically modified foods, in vitro planting, and the spread of closed ecological systems, are applied as a solution to increase food accessibility. In addition to these methods, using modern technologies under the title of precision agriculture have been proposed as ways to achieve food security. Early intervention to prevent the occurrence of unwanted events with the ability to monitor crops in all stages of production, from tillage to post harvest, are provided by using various methods, such as remote sensing and geographic information systems. In addition to the economic and environmental impacts of precision agriculture, expanding farmers' awareness through the use of modern technologies and the integration of scattered lands to achieve sustainability are known as social impacts of precision agriculture. In this manuscript we have tried to summarize the different methods of precision agriculture that could affect food security in its multiple branches.
Classification of hazelnuts is one of the values adding processes that increase the marketability and profitability of its production. While traditional classification methods are used commonly, machine learning and deep learning can be implemented to enhance the hazelnut classification processes. This paper presents the results of a comparative study of machine learning frameworks to classify hazelnut (Corylus avellana L.) cultivars (‘Sivri’, ‘Kara’, ‘Tombul’) using DL4J and ensemble learning algorithms. For each cultivar, 50 samples were used for evaluations. Maximum length, width, compression strength, and weight of hazelnuts were measured using a caliper and a force transducer. Gradient boosting machine (Boosting), random forest (Bagging), and DL4J feedforward (Deep Learning) algorithms were applied in traditional machine learning algorithms. The data set was partitioned into a 10-fold-cross validation method. The classifier performance criteria of accuracy (%), error percentage (%), F-Measure, Cohen’s Kappa, recall, precision, true positive (TP), false positive (FP), true negative (TN), false negative (FN) values are provided in the results section. The results showed classification accuracies of 94% for Gradient Boosting, 100% for Random Forest, and 94% for DL4J Feedforward algorithms.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
