Title: Разпознаване на символи с помощта на невронна мрежа Author: Гочев, Гочо Вълев; Gochev, Gocho Valev; Трифонов, Иван; Trifonov, Ivan; Шалявски, Цветан Митков; Shalyavski, Tsvetan Mitkov; Вучков, Иван Иванов; Vuchkov, Ivan Ivanov Date: 1995 Abstract: A preliminary processing has been done on the input image. Each character in the image is being extracted and centered within an input field. The information from this field is then feeded to a neural network for recognition of the character. A two layer network of sigmoid neurons has been chosen. Backpropagation learning rule is used. To ... Library:
