This paper focuses on an approach to build ontology for home energy management domain which is compatible with Suggested Upper Merged Ontology (SUMO). Our starting point in doing so was to study general classifications of home electrical appliances provided by various home appliances vendors and manufacturers. Various vendors and manufacturers use their own arbitrary classification instead of u...

In this paper, we study the multiclass classification problem. We derive a framework to solve this problem by providing algorithms with the complexity of a single binary classifier. The resulting multiclass machines can be decomposed into two categories. The first category corresponds to vector-output machines, where we develop several algorithms. In the second category, we show that the least-...

A key issue in machine learning is the ability to cope with recognition problems where one or more classes are under-represented with respect to the others. Indeed, traditional algorithms fail under class imbalanced distribution resulting in low predictive accuracy over the minority classes. While large literature exists on binary imbalanced tasks, few researches exist for multiclass learning. ...

In this work, we introduce the concept of Multiclass for language modeling and we compare it to the Polyclass model. The originality of the Multiclass is its capability to parse a string of classes/tags into variable length independent sequences. A few experimental tests were carried out on a class corpus extracted from the French « Le Monde » word corpus labeled automatically. This corpus cont...

We compare Naive Bayes and Support Vector Machines on the task of multiclass text classification. Using a variety of approaches to combine the underlying binary classifiers, we find that SVMs substantially outperform Naive Bayes. We present full multiclass results on two well-known text data sets, including the lowest error to date on both data sets. We develop a new indicator of binary perform...

OBJECTIVE To evaluate the anteroposterior short-term skeletal and dental effects on Class II malocclusion in growing patients following treatment with functional appliances (activators or twin block), extraoral traction, or combination appliances (appliances with both functional and extraoral traction components), based on published data. MATERIALS AND METHODS A literature search was carried ...

UNLABELLED There has been a paradigm shift within orthodontics in the use of lingual fixed appliances compared with the use of labial fixed appliances on the basis of perceived benefits and acceptance by patients. METHODS A matched case-control prospective longitudinal study of adult patients treated in the Orthodontic Department, Prince Philip Dental Hospital, Hong Kong. Group A consisted of...
