Title: Training of dnn-student by means of output distribution
Inventor: CHZHAO Zhuj
IPC: G06N3/02
Filed: 2014-09-12
Granted: 2018-09-11
Abstract: FIELD: computer equipment.SUBSTANCE: invention relates to the field of machine learning algorithms. To generate a DNN classifier by "learning" the DNN-student model based on a larger, more accurate DNN teacher model, a DNN student can be trained on the basis of unmarked training data by passing unmarked training data through a DNN teacher, which can be trained based on tagged data. Iterative process is used to train a DNN student by minimizing the divergence of the pin assignments based on the DNN teacher and student models. For each iteration before convergence, the difference in the outputs of these two DNNs is used to update the DNN student model, and the findings are determined again, using unmarked training data.EFFECT: technical result is an increase in the accuracy of the DNN (Deep Neural Network) model with a reduced size.10 cl, 7 dwg

Abstract: Изобретение относиться к медицине, а именно к способам лечения тинитуса. Осуществляют воздействие звуком в комбинации с транслингвальной нейростимуляцией. При этом лечение включает два этапа. На первом этапе определяют пороги слышимости пациента и оценивают частотную область генерации ушного шума. На втором этапе выполняют подавление ушного шума за счет звукового воздействия в комбинации с транслингвальной нейростимуляцией. При этом на втором этапе сигналы предъявляются через устройство для персонального прослушивания звука в область генерации ушного шума на основании данных, полученных на первом этапе. Для этого используют шум с шириной полосы 1 или 2 кГц, центральной частотой шума в пределах значений от 0,5 до 15 кГц. При этом пациент оповещает, слышит ли он собственный ушной шум на фоне звукового сигнала или нет, при помощи сигналов, подаваемых с пульта, находящегося у него в руке. В частном случае на первом этапе пациенту, через устройство для персонального прослушивания звука предъявляют тоны и белые шумы монаурально или бинаурально интенсивностью сигнала от 0 до 140 дБ. В частном случае предъявляют тоны звуковой полосы от 0,1 кГц до 16 кГц, белые шумы - полосовые с шириной полосы 1 и 2 кГц, центральная частота шума изменяется от 0,5 до 15 кГц, длительность сигналов 500 мсек, период предъявления 1 сек. В частном случае пациент либо самостоятельно выбирает звук, максимально схожий по звучанию и громкости с собственным ушным шумом, либо такой выбор проводят по реакциям или указаниям пациента. В частном случае на втором этапе сигналами служат отрезки белого шума длительностью 5 сек. В частном случае шумы разделяют паузой 5 сек. В частном случае транслингвальная нейростимуляция осуществляется с частотой импульсов 50-200 Гц с длительностью 20-35 мин при помощи неинвазивного нейростимулятора. Способ позволяет осуществить лечение любого вида тинитуса, за счет использования шума с центральными частотами от 0,5 до 15 кГц и шириной полосы 1 и 2 кГц, а так сократить сроки лечения. 11 з.п. ф-лы, 3 пр., 8 ил.
