Annotating images automatically is needed for indexing and searching images in a big database. Image annotation can be considered as a multi-class classification problem, where an image may require one or more labels. In this work, One-Against-All (OAA) multi-class ANNs architecture approach is proposed to classifying into multi-class. The extracted features from color and edge descriptors of an image are used as input of the model. Some experiments were performed to achieve the optimal number of hidden neurons of each neural network that can classify its corresponding target successfully. The empirical results outperform multiple label learning approach.
We can understand the artistic production within the professional field and as part of the curriculum in certain formations. Our proposal starts from a scenic project as a learning tool in the elementary school teacher\'s degree and how the management of this project can have repercussions on different transversal competences, that help to improve the student\'s performance and increase their knowledge related to the subject of Didactics of Musical Expression, coming to connect with reality, so that training can be useful not only from the specific competencies of the Curriculum. The vision regarding artistic production is closely linked to cultural management. Instead, we can understand that management must not only go through economic issues, but must also have an impact on social, educational, and sustainability. Music education teachers often make their own artistic productions, without having enjoyed along their formation of mere knowledge that involves the profession, reducing in the end to a simple classroom show, which in the best of cases see the family and Friends of the student body. Our first step has been to find out, through the prospective elementary teacher, whether a stage project could help meaningful learning, outside and within the classroom. Our second step would be, how these third step students in elementary school can be the producer of their own project and what competencies can develop.
