在创新驱动发展战略深入推进的当下，企业研发投入成为经济高质量发展的核心动力，而研发费用加计扣除、高新技术企业税收优惠等政策，既激发了企业创新活力，也催生了部分企业的研发操纵行为。这类通过虚增研发支出、调整会计处理方式套取政策红利的 ...

在使用支持向量机（Support Vector Machine, SVM）时，模型参数的选择是影响模型性能的核心环节。SVM作为一种基于统计学习理论的监督学习算法，其参数配置直接决定了分类边界的形状、 C是SVM中控制模型复杂度与误分类惩罚的平衡因子。 核函数的选择及其参数配置 ...

This work includes two high performance recognizers. The SVM based recognizer has an accuracy of 90%. It first applies projection-based algorithm to the input image, then use a pre-trained SVM model ...

Three machine learning algorithms—Logistic Boosting, Random Forest, and Support Vector Machines (SVM)—were evaluated for anomaly detection in IoT-driven industrial environments. A real-world dataset ...

Abstract: This paper presents a chatbot model designed to detect stress in users through simple yes-or-no questions. Utilizing a Support Vector Machine (SVM) algorithm, the model achieves high ...

支持向量机（SVM）是一种常用的分类算法，它特别擅长处理具有线性可分特征的数据集。SVM的核心思想是找到一个超平面，将数据集中的不同类别尽可能地分开，并且最大化样本间的间隔。 1. 数据生成与SVM模型训练 首先，我们生成两个类别的数据点，每个类别20 ...

Due to theintricate and interdependent nature of the smart grid, it has encountered an increasing number of security threats in recent years. Currently, conventional security measures such as ...

Hyperparameter tuning is a critical step in optimizing machine learning models for optimal performance. It involves selecting the best combination of hyperparameters, such as regularization strength, ...

Support Vector Machines (SVM) are widely used in machine learning for classification and regression tasks. However, the performance of an SVM model depends heavily on its parameter settings, such as ...

Abstract: In this work, an EMG-based signal implemented through a Python programming methodology classifier is presented. The developed system is based on the flexor digitorum profundus muscle signals ...
