Abstract
Deep learning methods have reached state of the art performance in several areas. Although research in this field have achieved excellent results in benchmark datasets, there is lack of understanding about how the methods work, and applications yet to be investigated, in particular when going beyond standard convolutional neural networks architectures. In this project we propose the use of feature learning applied to the analysis of low-altitude remote sensing for precision agriculture and the sketch-based image retrieval. Each task has its own challenges, but in common there is limited labelled data to be trained with. Those can be solved using deep learning framework by exploring new architectures based on auto-encoders, Siamese networks and also generative models. We propose to evaluate the models not only using benchmark datasets, but also assess the quality of the representations by using visualisation and projection techniques as a way to analyse the output feature spaces. The expected results include the development of models that, trained with limited availability of labels (or even unsupervised), are still able to generalise for unseen data and categories. In addition to the contributions in the computer vision field, we expect to advance the state-of-the-art on the applications. (AU)
