Speech recognition for interaction with a robot in noisy environment

One of the main problems with speech recognition for robots is noise. In this paper we propose two methods to enhance the robustness of continuous speech recognition in noisy environment. We show that the accuracy of recognition can be improved by better weighting the language model in the decision process. The second proposed method is based on language model adaptation. The experiments showed...

In this paper, we present a deep neural network (DNN)-based acoustic scene classification framework. Two hierarchical learning methods are proposed to improve the DNN baseline performance by incorporating the hierarchical taxonomy information of environmental sounds. Firstly, the parameters of the DNN are initialized by the proposed hierarchical pre-training. Multi-level objective function is t...

W A B W A B Input Hidden Output

A modiication to neural network training algorithms is proposed which decorrelates certain weights within the network while minimising the mean squared error. The technique was developed to facilitate neural network interpretation in image processing problems, partly by allowing to initialise all network weights with one xed, low value. However, it can also be applied to classiica-tion tasks in...

Prohledávání dokumentů ve vektorovém modelu

Abstrakt. Information retrieval se mj. zabývá ukládáním a prohledáváním dokumentů. Vektorový model reprezentuje dokument jako vektor mnohorozměrného prostoru. Většina jeho implementací je bohužel efektivní jen pro malé dimenze, proto jsou hledány metody, jak dimenzi vektorů dokumentů snížit. V tomto článku ukazujeme jednu z možností – využití signatur (bitových řetězců pevné délky) které byly v...
