<p>Typhoid fever is one of the severe infectious human diseases in Africa. Out of an estimated 11–21 million cases of typhoid fever and 200,000 deaths occur worldwide each year. Other elements contribute to this situation and particularly in rural areas where patients to doctors ratio is very low, lack of medical facilities and costly tests. There are a number of tests available presently, from molecular to immunological and biochemical to microbiological. However, Users are unsatisfied due to delays in getting test results and Imprecise diagnosis. Misdiagnosis is usually experienced since most health care facilities use only Widal test without confirmation of results with a second test method. In addition, the diagnosis of Typhoid involves several levels of uncertainties. Patients cannot tell exactly how they feel, doctors and nurses cannot tell exactly what they observe. There is therefore, an urgent need to develop a rapid, highly sensitive and cheap diagnostic tool for diagnosis of typhoid fever.</p>
The absence of a reliable diagnosis pushes rural populations towards self-medication with all the consequences that this entails, in particular drug poisoning which can lead to death. As such, we want to develop a new method to diagnose Typhoid early, quickly, and with accurate results at a low cost. We propose a hybrid diagnosis method with a Deep Learning algorithm applied on blood serum images which seems to be the best accepted test by laboratory technicians. We use CNNs as algorithms on the collected images to train the algorithm. We use a second algorithm Rough Set Theory. This algorithm based on symptoms variables which are structured data collected from medical doctors allow us not only to confirm the diagnosis but above all to determine the level of severity of the disease and serve as a Decision Support System. The two algorithms will be part of a mobile app connected to an optical microscope, the phone camera will scan images from the slides on the microscope and classify them into Normal or Infected. In a series of rapid spotlights, we present tools and frameworks that serve as cornerstones for the envisioned diagnostics system including: 1) Values, influences and forces that shape the diagnostics 2) AI solutions to be used; 3) Data sources 4) Ethics and governance model.

<p>This presentation is about the development and trajectory of Heurist (HeuristNetwork.org), a shared, integrated, extensible data infrastructure (model, build, manage, analyse, visualise, share, publish via integrated CMS) for Humanities research capable of handling the needs of many heterogeneous projects on a single standalone service*, with optional integration across multiple servers by a coordinating index (itself based on Heurist).</p> <p>Humanities data are interesting (both technically ...

<p>Developed from 1995 onward, Prospero is a framework for longitudinal analysis of text corpora. Based on dictionaries and semi-automatic classification, it mainly allows its user to combine approaches of statistical computation, co-occurrence network and search for nested patterns. Inspired by pragmatic sociology, it focuses on the multiple forms of expression and argumentation used by actors, on language regimes and on the identification of transformations occurring in the research case. ...

<p>I am a social scientist who mostly teaches and conducts qualitative research, but I am also a programmer. Over the years, I have contributed to a variety of free and open source software projects, and since 2019, I have developed and maintained <code>textnets</code>, a Python package for text analysis that represents collections of texts as networks of documents and words, providing novel possibilities for the visualization and analysis of texts. In my field, such software development efforts ...

<p>The writing of web publications mixing data visualization and textual prose opens novel opportunities for connecting evidence, arguments and narrative in social sciences communities. Such a practice poses a variety of challenges in terms of website design and development ; but also and maybe more importantly, it asks for experimenting specific workflows for coordinating a variety of expertises ranging from social sciences disciplines (history, sociology, etc.) to data science, information ...

<p>This talk will show a new Python tool called Livemark, which is designed for data journalism software education, and documentation writing. Using Livemark, you can collect and present data with interactive tables, charts, and other elements without leaving a text editor. You can also write documentation with live script execution similar to a lightweight version of a Jupiter Notebook. This talk will demo Livemark and will be well-suited for a technical and non-technical audience that is ...
