Portugal for Chinese Tourists, an e-guide
This project consists in an electronic guide (e-guide) dedicated to Chinese
tourists who are interested and willing to travel to Portugal. This e-guide
introduces Portugal to Chinese tourists, filling in an identified cultural gap, and
enhancing Chinese tourists’ knowledge about this destination.
In this project, Chinese tourists’ travel preferences and demands are
analyzed based on two questionnaires (one a priori and one a posteriori). Based
on these results, customized tourism information and travel plans were generated.
The preparation and development processes of this e-guide are presented in
detail in this project.
This project is the final work of the Master’s degree in Tourism and
Communication, leading to the achievement of the degree of Master by Escola
Superior de Hotelaria e Turismo do Estoril, Faculdade de Letras e Instituto de
Geografia e Ordenamento do Território.Neste projeto desenvolveu-se um guia eletrónico (e-guia), destinado a
turistas chineses interessados e dispostos a viajar para Portugal. Este guia
eletrónico também serve como um meio de apresentação de Portugal aos turistas
chineses, preenchendo lacunas culturais identificadas e aumentando o
conhecimento dos turistas chineses sobre este destino.
Neste projeto, as preferências e exigências de viagem dos turistas chineses
são analisadas com base em dois questionários (um a priori e outro a posterior).
Com base nesses resultados, foram geradas informações personalizadas sobre
turismo e desenvolvidos planos de viagem. Os processos de preparação e
desenvolvimento deste guia eletrónico são apresentados em detalhe neste
projeto.
O projeto corresponde ao trabalho final do Mestrado em Turismo e
Comunicação, levando à obtenção do grau de Mestre a atribuir pela Escola
Superior de Hotelaria e Turismo do Estoril, pela Faculdade de Letras e pelo

ASD Biomarker Detection on fMRI Images: Feature learning with Data Corruptions by Analyzing Deep Neural Network Classifier Outcomes
Autism spectrum disorder (ASD) is a complex neurological and developmental disorder. It emerges early in life and is generally associated with lifelong disability. Finding the biomarkers associated with ASD is extremely helpful to understand the underlying roots of the disorder and find more targeted treatment. Previous studies suggested brain activations are abnormal in ASDs, hence functional magnetic resonance imaging (fMRI) has been used to identify ASD. In this work we addressed the problem of interpreting reliable biomarkers in classifying ASD vs. control; therefore, we proposed a 2-step pipeline: 1) classifying ASD and control fMRI images by deep neural network, and 2) finding which brain regions are important for identifying ASD and control. Specifically, in step 2, we used the trained classifier to estimate the feature importance by measuring the prediction distribution change as a function of input image with the corrupted region. However, there is no certain way to corrupt the data without adding side effects. Thus, we aggregated two opposite corruption methods: a) blackout and b) add Gaussian noise. Biomarkers found by the 2-step pipeline were verified by Neurosynth brain function decoding. Several key innovations in our research include: i) we created an innovative pipeline for learning image data feature by analyzing the classifier outcomes with corruptions; ii) we proposed a deep learning strategy for classifying 4D data; iii) we aggregated different corruption methods for feature importance analysis, and iv) our neurological interpretation of the final results showed evidence that there were meaningful fMRI biomakers on fMRI for ASD
Semantic Image Segmentation via Deep Parsing Network
This paper addresses semantic image segmentation by incorporating rich
information into Markov Random Field (MRF), including high-order relations and
mixture of label contexts. Unlike previous works that optimized MRFs using
iterative algorithm, we solve MRF by proposing a Convolutional Neural Network
(CNN), namely Deep Parsing Network (DPN), which enables deterministic
end-to-end computation in a single forward pass. Specifically, DPN extends a
contemporary CNN architecture to model unary terms and additional layers are
carefully devised to approximate the mean field algorithm (MF) for pairwise
terms. It has several appealing properties. First, different from the recent
works that combined CNN and MRF, where many iterations of MF were required for
each training image during back-propagation, DPN is able to achieve high
performance by approximating one iteration of MF. Second, DPN represents
various types of pairwise terms, making many existing works as its special
cases. Third, DPN makes MF easier to be parallelized and speeded up in
Graphical Processing Unit (GPU). DPN is thoroughly evaluated on the PASCAL VOC
2012 dataset, where a single DPN model yields a new state-of-the-art
segmentation accuracy.Comment: To appear in International Conference on Computer Vision (ICCV) 201
