This paper aims at settling the shortcomings in SVM such as it is sensitive to the distribution of samples near separating margin. Inspired by spread directions of manifold, we propose a new SVM learning method. This method, constructs scalar field and corresponding gradient field in observation space according to the classification decision function, and(More)
The traditional unified power quality controller (UPQC) topology based on modular cascade structure usually requires line transformer to effectively isolate the DC bus of each subunit when used in high voltage applications. The line transformer may bring various problems such as increased cost, magnetic saturation, surge current, phase shift and so on. In(More)
BACKGROUND A thoracoscopic approach for repair of esophageal atresia (EA) with tracheoesophageal fistula (TEF) has become a standard procedure in many pediatric surgical centers. However, whether thoracotomy or thoracoscopy offer advantages in terms of surgical outcomes is not known. METHODS To evaluate the efficacy and safety of thoracoscopic repair (TR)(More)
