 To meet these challenges, attention should be paid to the following aspects: ​ To meet these challenges, attention should be paid to the following aspects: ​
         * //Handling Variabilities:​ // Variability of compositions (e.g. identifying dominated workflows, managing requirements between WF components);​ Variability of performance metrics (e.g. dependencies among metrics); Variability of Data Sets (e.g. images, text) and consequently how we represent them (meta features); Variability of platforms; Variability of algorithms and preprocessing algorithms (i.e. characterization to distinguish and automate the compositions);​ Variability of hyper-parameter tuning strategies (i.e. dependency with workflows); etc.         * //Handling Variabilities:​ // Variability of compositions (e.g. identifying dominated workflows, managing requirements between WF components);​ Variability of performance metrics (e.g. dependencies among metrics); Variability of Data Sets (e.g. images, text) and consequently how we represent them (meta features); Variability of platforms; Variability of algorithms and preprocessing algorithms (i.e. characterization to distinguish and automate the compositions);​ Variability of hyper-parameter tuning strategies (i.e. dependency with workflows); etc.

-We have a two-year experience on this subject which has enabled us to (I) eliminate some approaches (e.g. modeling knowledge as a system of constraints because it generates on our current basis more than 6 billion constraints),​ (ii) lay the foundations for a platform for collecting experiences and presenting to the user (Camillieri et al., 2016) (see [[http:// http://​rockflows.i3s.unice.fr/​]]),​ (iii) study the ML workflows to predict workflows (Master internships Luca Parisi, Miguel Fabian Romero Rondon and Melissa Sanabria Rosas), (iv) address platform evolution introducing deep learning workflows (see Melissa’s Report). ​+We have a two-year experience on this subject which has enabled us to (I) eliminate some approaches (e.g. modeling knowledge as a system of constraints because it generates on our current basis more than 6 billion constraints),​ (ii) lay the foundations for a platform for collecting experiences and presenting to the user (Camillieri et al., 2016) (see [[http:// http://​rockflows.i3s.unice.fr/​]]),​ (iii) study the ML workflows to predict workflows (Master internships Luca Parisi, Miguel Fabian Romero Rondon and Melissa Sanabria Rosas), (iv) address platform evolution ​by introducing deep learning workflows (see Melissa’s Report). ​
  
 The thesis must investigate the research around the selection of algorithms, considering the automatic composition of workflows and supporting dynamic evolutions. It is therefore a thesis in software engineering research but to address one of the current most central problems in machine learning. The thesis must investigate the research around the selection of algorithms, considering the automatic composition of workflows and supporting dynamic evolutions.
