Abstract (EN): 
Current  data  mining  tools  are  characterized  by  a  plethora  of  algorithms  but  a  
lack  of  guidelines  to  select  the  right  method  according  to  the  nature  of  the  
problem  under  analysis.  Producing  such  guidelines  is  a  primary  goal  by  the  
field  of  meta-learning;  the  research  objective  is  to  understand  the  interaction  
between  the  mechanism  of  learning  and  the  concrete  contexts  in  which  that  
mechanism  is  applicable.  The  field  of  meta-learning  has  seen  continuous  
growth in the past years with interesting new developments in the construction 
of  practical  model-selection  assistants,  task-adaptive  learners,  and  a  solid  
conceptual   framework.   In   this   paper,   we   give   an   overview   of   different   
techniques  necessary  to  build  meta-learning  systems.  We  begin  by  describing  
an   idealized   meta-learning   architecture   comprising   a   variety   of   relevant   
component  techniques.  We  then  look  at  how  each  technique  has  been  studied  
and  implemented  by  previous  research.  In  addition,  we  show  how  meta-
learning  has  already  been  identified  as  an  important  component  in  real-world  
applications.
