Abstract

In general, the investigation of NN (neural network) computing systems requires the management of a significant number of simultaneous distinct algorithms, such as parallel computing, fault tolerance, classification, and data optimization. Supervised learning for NN originally comes from certain parameters, such as self-revised learning, input learning datasets, and multiple second learning processes. Specifically, the operation continues to adjust the NN connection synapses' weight to achieve a self-learning computer system. The current article is aimed at developing the CC (correlation coefficient) assignment scheme adaptively joint with the FS (feature selection) categories to pursue the solutions utilized in solving the restrictions of NN computing. The NN computing system is expected to solve high-dimensional data, data overfitting, and strict FS problems. Hence, the Fruits-360 dataset is applied in the current article, that is, the variety of fruits, the sameness of color, and the differences in appearance features are utilized to examine the NN system accuracy, performance, and loss rate. Accordingly, there are 120 different kinds with a total of 20,860 fruit image datasets collected from AlexNet, GoogLeNet, and ResNet101, which were implemented in the CC assignment scheme proposed in this article. The results are employed to verify that the accuracy rate can be improved by reducing strict FS. Finally, the results of accuracy rate from the training held for the three NN frameworks are discussed. It was discovered that the GoogLeNet model presented the most significant FS performance. The demonstrated outcomes validate that the proposed CC assignment schemes are absolutely worthwhile in designing and choosing an NN training model for feature discrimination. From the simulation results, it has been observed that the FS-based CC assignment improves the accurate rate of recognition compared to the existing state-of-the-art approaches.

摘要

一般来说,神经网络 (NN) 计算系统的研究需要管理大量同时存在的不同算法,如并行计算、容错、分类和数据优化。神经网络的监督学习最初来自某些参数,如自修正学习、输入学习数据集和多个二次学习过程。具体来说,该操作会继续调整 NN 连接突触的权重,以实现自我学习的计算机系统。本文旨在开发与特征选择 (FS) 类别自适应联合的 CC(相关系数)分配方案,以寻求解决 NN 计算限制的解决方案。NN 计算系统有望解决高维数据、数据过拟合和严格 FS 问题。因此,本文应用了 Fruits-360 数据集,即水果的种类、颜色的一致性和外观特征的差异,以检验 NN 系统的准确性、性能和丢包率。因此,有 120 种不同的水果,共有 20860 个水果图像数据集,分别来自 AlexNet、GoogLeNet 和 ResNet101,这些数据集在本文提出的 CC 分配方案中实现。结果用于验证通过减少严格 FS 可以提高准确率。最后,讨论了在三个 NN 框架中进行训练的准确率结果。发现 GoogLeNet 模型表现出最显著的 FS 性能。结果验证了所提出的 CC 分配方案在设计和选择用于特征区分的 NN 训练模型方面是绝对值得的。从模拟结果可以看出,基于 FS 的 CC 分配比现有最先进的方法提高了识别的准确率。
