The main motives are both to learn about neural networks and the potential of automatic bird recognition in nature conservation. Birds react rapidly to changes in the environment and observing birds using neural networks could produce useful information for nature conservation. Birdwatching is popular as a hobby and also birdwatchers could benefit from automatic recognition of bird species. In addition, the Finnish National Agency for Education aims to teach children to identify species and to learn about plants and animals in general. Neural networks could be utilized also in teaching. First, neural networks are presented in general, after which the utilization of neural networks in bird recognition is examined. The thesis also covers convolutional neural networks since they have played a key role in image recognition as well as sound recognition and they are also applied in bird recognition. The thesis is conducted as a literature review and the source material is mainly formed of articles about the theoretical background of neural networks, and reports in which neural networks are utilized in competitions of automatic bird recognition by sound. Recognizing birds using neural networks has been more successful than using other technologies but the practical benefits are limited for instance because of relatively intensive needs for computing power.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2018-07-03T09:14:09Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2018-07-03T09:14:09Z (GMT).
