One-class support vector machine (OC-SVM) is a common algorithm to solve one-class classification (OCC) problem. Weighted OC-SVM (WOC-SVM) is an improved algorithm based on OC-SVM, which assigns a weight to each sample through a specific weight calculation method so as to improve the ...
One-Class Support Vector Machine在过去20里逐渐流行,就是为了解决这样的问题。本篇博客对One-Class SVM进行介绍,而One-Class SVM也会应用到我的论文中。 1. Just One Class? 首先先看下我们的问题,我们希望确定新的训练数据是否属于某个特定类?怎么会有这样的应用场景呢?比方说,我们要判断一张照片里的人脸,...
Among the variety of methods and algorithms proposed to deal with this problem, boundary based methods include One-class support vector machine (OC-SVM) is considered as an effective and outstanding one. Nevertheless, extremely sensitivity to the presence of outliers and noises in the training set...
Therefore, we applied multistage one-class Support Vector Machine (OC-SVM) to detect such serious attacks. At the first stage, two training data are ... S Araki,Y Yamaguchi,H Shimada,... 被引量: 11发表: 2014年 Traffic Anomaly Detection Using Multi-Dimensional Entropy Classification in Backbo...

The One-Class Support Vector Machine (OC-SVM) is all unsupervised learning algorithm, identifying unusual or outlying points (outliers) from a given dataset. In OC-SVM, it is required to set the regularization hyperparameter and kernel hyperparameter in order to obtain a good estimate. Generally...
为了避免 one-class 支持向量机(one-class Support Vector Ma- one-class 支持向量机过拟合的问题,文献[5J将粗糙集理论引 chine ,OC-SVM) [3J 是由 Schölkopf 等人提出的一种新型的机 入到 one-class 支持向量机中,提出了新的 one-class 支持向量 器学习方法,主要用于处理一类问题或者聚类问题。首先它 机...
In this paper, a Hybrid IDS (HIDS) is proposed by combining the C5 decision tree classifier and One Class Support Vector Machine (OC-SVM). HIDS combines the strengths of SIDS) and Anomaly-based Intrusion Detection System (AIDS). The SIDS was developed based on the C5.0 Decision tree ...
Secondly, multispectral samples extracted by VIIRS active fires are used for training a One-Class Support Vector Machine (OC-SVM) classification that uses cumulative distribution functions criteria. The active fire data were screened to prevent extraction of unrepresentative BA samples and combined with ...
Disclosed is an automatic video summarization device and method using a fuzzy OC-SVM (one-class support vector machine) algorithm. A user's subjective decision is reflected in order to generate an effective video summary, and a method for generating flexible video summary information which satisfies...
