    <title language="eng">Handwritten dynamics assessment through convolutional neural networks</title>
    <abstract language="eng">Background and objective&#13;
Parkinson’s disease (PD) is considered a degenerative disorder that affects the motor system, which may cause tremors, micrography, and the freezing of gait. Although PD is related to the lack of dopamine, the triggering process of its development is not fully understood yet.&#13;
Methods&#13;
In this work, we introduce convolutional neural networks to learn features from images produced by handwritten dynamics, which capture different information during the individual’s assessment. Additionally, we make available a dataset composed of images and signal-based data to foster the research related to computer-aided PD diagnosis.&#13;
Results&#13;
The proposed approach was compared against raw data and texture-based descriptors, showing suitable results, mainly in the context of early stage detection, with results nearly to 95%.&#13;
Conclusions&#13;
The analysis of handwritten dynamics using deep learning techniques showed to be useful for automatic Parkinson’s disease identification, as well as it can outperform handcrafted features.</abstract>

    <title language="eng">A survey on Barrett's esophagus analysis using machine learning</title>
    <abstract language="eng">This work presents a systematic review concerning recent studies and technologies of machine learning for Barrett's esophagus (BE) diagnosis and treatment. The use of artificial intelligence is a brand new and promising way to evaluate such disease. We compile some works published at some well-established databases, such as Science Direct, IEEEXplore, PubMed, Plos One, Multidisciplinary Digital Publishing Institute (MDPI), Association for Computing Machinery (ACM), Springer, and Hindawi Publishing Corporation. Each selected work has been analyzed to present its objective, methodology, and results. The BE progression to dysplasia or adenocarcinoma shows a complex pattern to be detected during endoscopic surveillance. Therefore, it is valuable to assist its diagnosis and automatic identification using computer analysis. The evaluation of the BE dysplasia can be performed through manual or automated segmentation through machine learning techniques. Finally, in this survey, we reviewed recent studies focused on the automatic detection of the neoplastic region for classification purposes using machine learning methods.</abstract>

    <title language="eng">Barrett's Esophagus Identification Using Color Co-occurrence Matrices</title>
    <abstract language="eng">In this work, we propose the use of single channel Color Co-occurrence Matrices for texture description of Barrett’sEsophagus (BE)and adenocarcinoma images. Further classification using supervised  learning techniques, such as Optimum-Path Forest (OPF), Support  Vector Machines with Radial Basisunction (SVM-RBF) and Bayesian classifier supports the contextof automatic BE and adenocarcinoma  diagnosis. We validated three approaches of classification based on  patches, patients and images in two datasets (MICCAI 2015 and  Augsburg) using the color-and-texture descriptors and the machine learning techniques. Concerning MICCAI 2015 dataset, the best results were obtained using the blue channel for the descriptors and the  supervised OPF for classification purposes in the patch-based   approach,  with sensitivity nearly to 73% for positive adenocarcinoma  identification and specificity close to 77% for BE (non-cancerous) patch classification. Regarding the Augsburg dataset, the most   accurate results were also obtained using both OPF classifier and  blue channel descriptor for the feature extraction, with sensitivity close to 67% and specificity around to76%. Our work highlights new advances in the related research area and provides a promising  technique that combines color and texture information, allied to  three different approaches of dataset pre-processing aiming to  configure robust scenarios for the classification step.</abstract>
