The last radiology report by the Royal College of Radiologists has identified the pressure that radiologists are suffering due to excessive workloads levels. This is due to the availability of a growing number of images and a short time to provide the report, making the diagnosis a difficult process. This suggests that the visualization of the radiologist should be accompanied, somehow, by an automatic "explainable" process. In this paper, we give emphasis to the breast cancer as it is one of the most common types of cancer in women. Specifically, we deal with mammography images because it is a primary step to be accomplished in an early radiological breast diagnosis. Although machine learning models are being used in medical imaging, these models still struggle to provide enough interpretability to provide reliability in the decision-making process of the radiologist. In this work, we explore solutions that improve an explainable model’s performance in mammography classification. We propose the use counterfactual information for improving the breast classification task. We compare multiple approaches to the integration of counterfactual information into the training process. The experimental evaluation testifies that incorporating such counterfactual information improves both balanced accuracy and interpretability for the breast classification task.

Traditional evaluation metrics for learned models that report aggregate scores over a test set are insufficient for surfacing important and informative patterns of failure over features and instances. We introduce and study a method aimed at characterizing and explaining failures by identifying visual attributes whose presence or absence results in poor performance. In distinction to previous work that relies upon crowdsourced labels for visual attributes, we leverage the representation of a separate robust model to extract interpretable features and then harness these features to identify failure modes. We further propose a visualization method aimed at enabling humans to understand the meaning encoded in such features and we test the comprehensibility of the features. An evaluation of the methods on the ImageNet dataset demonstrates that: (i) the proposed workflow is effective for discovering important failure modes, (ii) the visualization techniques help humans to understand the extracted features, and (iii) the extracted insights can assist engineers with error analysis and debugging.

Spatial OLAP (SOLAP) systems allow to explore and analyze huge volume of georeferenced data by means of pivot tables, graphical displays and maps. In the last years, SOLAP and Spatial Data Warehouses has received a lot of attention from the academic and industrial communities, who mainly focus on logical and physical data models to improve SOLAP queries performance. Although, geovisualization is essential for effective SOLAP analysis, few works propose advanced methods for the visualization of SOLAP queries results using cartographic displays. In this work, we present some geovisualization methods to reach an effective visualization of pivot table data over maps. We implement these proposals in a web-based SOLAP system, and we use a real case study concerning the analysis of the agro-biodiversity data for the demo scenario.

It is presented in this article a web-based tool named OncoPrint++. OncoPrint++ is a tool integrated with traditional OncoPrint/heatmap and enhanced functions and features for processing, visualizing and analyzing clinicogenomics data in oncology. OncoPrint++ functions as an all-in-one tool primarily designed for oncology studies, but it could be extended for general clinical bioinformatics and genomics. It will be available to use for free at GitHub/AWS.

Due to the advantages of improving system operational effectiveness, the manned and unmanned cooperative operational methods are increasingly being applied in modern battlefields. However, in complex scenarios, the information interaction between manned aircraft and unmanned aerial vehicles can lead to issues such as poor timeliness and low efficiency in resource scheduling. Constructing an architecture framework for manned and unmanned system based on DoDAF to design the top-level structure of the system can solve the problem of poor system interoperability. In this paper, We propose a method of constructing a DoDAF model for the scenario and verifying the logical consistency of the system task architecture. We design an information exchange process for manned and unmanned cooperative reconnaissance scenario and verify the logical self-consistency of the process to improve system interoperability. In addition, We apply the STK tool to construct a scenario visualization model, which more intuitively reflects the information interaction relationship of the system in multiple domains, to further jointly verify the logical correctness of information interaction.

With the need for explainable AI, several visualization methods have been developed to explore neural networks. Our proposed work seeks to isolate and generate image features of input data using any neural network. We employed a modified gradient ascent algorithm with a smoothed gradient loss function for image-to-image feature generation.
