    Malaria eradication of the worldwide is currently one of the main WHO’s global goals. In this work, we focus on the use of human-machine interaction strategies for lowcost fast reliable malaria diagnostic based on a ...
  • EM based algorithms for Malaria diagnose via crowdsourcing 

    Diaz Vilor, Carles (Universitat Politècnica de Catalunya, 2017)
    Bachelor thesis
    Open Access
    We live in a world in which medicine and technology are more united than ever. That is why in the last few years, lots of research groups initially dedicated to the development of technologies, have started to investigate ...
  • Impact of noisy annotators’ reliability in a crowdsourcing system performance

    Crowdsourcing is a powerful tool to harness citizen assessments in some complex decision tasks. When multiple annotators provide their individual labels a more reliable collective decision is obtained if the individual ...
  • Unsupervised ensemble classification with correlated decision agents 

    Cabrera-Bean, Margarita; Pagès Zamora, Alba Maria; Diaz Vilor, Carles (2019-07-01)
    Article
    Open Access
    Decision-making procedures when a set of individual binary labels is processed to produce a unique joint decision can be approached modeling the individual labels as multivariate independent Bernoulli random variables. ...
  • Unsupervised online clustering and detection algorithms using crowdsourced data for malaria diagnosis 

    Pagès Zamora, Alba Maria; Cabrera-Bean, Margarita; Diaz Vilor, Carles (2019-02-01)
    Article
    Open Access
    Crowdsourced data in science might be severely error-prone due to the inexperience of annotators participating in the project. In this work, we present a procedure to detect specific structures in an image given tags ...
