With the advancement of data processing technology, it is a significance task for machine learning to handle massive amounts of data. The traditional classification method is a supervised learning method, which requires a large number of labeled samples. But it is difficult to achieve. In this paper, a semi-supervised learning algorithm combining co-training with support vector machine (SVM) classification...
A variety of problems are related to real-world gesture recognition, such as continuous data streams, concept drift, novel and outlier samples, noise, scarcity of manually labeled data, on-line classification and the fact that the same gesture may implement in different way. Two important features should be included in the classifier to overcome these problems, which are the ability of detecting the...
The goal of email classification is to classify user emails into spam and legitimate ones. Many supervised learning algorithms have been invented in this domain to accomplish the task, and these algorithms require a large number of labeled training data. However, data labeling is a labor intensive task and requires in-depth domain knowledge. Thus, only a very small proportion of the data can be labeled...
The identification of phyllosilicates by NASA's CRISM (Compact Reconnaissance Imaging Spectrometer for Mars) strongly suggests the presence of water-related geological processes. A variety of water-bearing phyllosilicate minerals have already been identified by several research groups utilizing spectral enrichment techniques and matching phyllosilicate-rich regions on the Martian surface to known...
In this paper, we present a modified self-training semi-supervised SVM algorithm. In order to demonstate its validity and effectiveness, we carry out some experimentswhich prove that our method is better than the former algorithm. Using our modified self-training semi-supervised SVM algorithm, we can save much time for lableling the unlabelled data.
In the predictive modeling tasks, a clear distinction is often made between learning problems that are supervised or unsupervised, the first involving only labeled data (training patterns with known category labels) while the latter involving only unlabeled data. There is a growing interest in a hybrid setting, called semi-supervised learning, in semi-supervised classification, the labels of only...
Supervised and unsupervised learning are two well disseminated and discussed paradigms which define how image classification techniques extract knowledge about the data. A recent learning paradigm, called semi-supervised, comes to solve some limitations of supervised learning, as the amount of information needed to conduce an appropriated learning process. Different models of semi-supervised learning...
Most previous approaches to automatic audio events (AEs) annotation are based on supervised learning which relies on the availability of a labeled corpus to train classification models. However, instance annotation is often difficult, expensive, and time consuming. In this paper, we apply semi-supervised learning with transductive Support Vector Machine (TSVM) algorithm to automatic AEs annotation...
In real world learning problems it is often the case that while the amount of labeled training data is limited, the amount of raw, unlabeled data available is vast. It is thus beneficial to develop ways of exploiting the large amount of unlabeled data to maximize the utility of each labeled sample. We examine this ldquosemi-supervisedrdquo learning problem in the context of a flexible arm with complex...
We consider the problem of semi-supervised learning (SSL) from general unlabeled data, which may contain irrelevant samples. Within the binary setting, our model manages to better utilize the information from unlabeled data by formulating them as a three-class (-1,+1, 0) mixture, where class 0 represents the irrelevant data. This distinguishes our work from the traditional SSL problem where unlabeled...
