We propose a two-stage training for the multilayer perceptron (MLP). The first stage is bottom-up, where we use a class separability measure to conduct hidden layer training and the least squared error criterion to train the output layer. The second stage is top-down, we use a criterion derived from classification error rate to further train the network weights. We demonstrate the effectiveness...

BACKGROUND Breast cancer and cervical cancer are the most common cancers among women in the world. Many studies on the early detection of cancer have been conducted among women worldwide, but few studies have been performed in the world on female teachers regarding breast self-examination (BSE), mammography (MMG) and Pap smear test (PST). As teachers interact with students, this could play an i...

This article proposes offline language-free writer identification based on speeded-up robust features (SURF), goes through training, enrollment, and identification stages. In all stages, an isotropic Box filter is first used to segment the handwritten text image into word regions (WRs). Then, the SURF descriptors (SUDs) of word region and the corresponding scales and orientations (SOs) are extr...

levels of central control. Although Walter Cannon clearly articulated the impact of emotion and other psychological processes on autonomic states (Cannon 1928), he viewed the autonomic nervous system largely as a homeostatic regulatory mechanism (Cannon 1929). Recent research, however, has revealed a re-representation and layering of autonomic functions from the spinal cord to rostral brain net...

The article considers the intermediary function of languages used at stage preparation foreign applicants for admission to Russian universities. In a situation when majority foreigners’ proficiency language is not satisfactory, process studying special disciplines significantly slowed down, and lack subject knowledge does allow students successfully master their chosen specialty. order overcome...

Objective: A question raised here as to whether exercise training combined with Mg supplementation could improve the symptoms of neuropathic pain such as the thermal hyperalgesia more effectively than either of the two alone. This study aimed to investigate the combined effect of swim training and Mg supplementation on thermal hyperalgesia in streptozotocin (STZ) induced diabetic rats. Materia...

OBJECTIVES To investigate the physiological effects of two different three times a week, eight week training programmes on the aerobic fitness of nine to ten year old girls. METHODS Treadmill determined peak VO2, submaximal heart rates, and submaximal blood lactate were the criterion measures. Seventeen girls completed a programme of "aerobics" training where sessions lasted 20-25 minutes. Ei...

Home-based exercise training, applied as the primary treatment in patients with intermittent claudication, has produced inconsistent effects on walking capacity in previous published studies. The aim of the present study was to evaluate whether a home-based exercise training program could maintain improved walking capacity and other functional variables achieved through a supervised exercise tr...
