This was the 15th biennial conference in the CAEPIA series, which was started back in 1985. Previous editions took place in Madrid, Alicante, Ma´laga, Murcia, Gij´on, Donostia, Santiago de Compostela, Salamanca, Seville, and La Laguna. This editionofCAEPIAwascoordinatedwithvariousindependent conferences: IX Spanish Congress on Metaheuristics, Evolutive and Bioinspired Algorithms (MAEB 2013), IV Symposium of Fuzzy Logic and Soft Computing (LFSC), VII Symposium of Data Mining Theory and Applications (TAMIDA 2013), In- formation Fusion 2013 (FINO 2013) and Agent and Multiagent Systems: From TheorytoPractice(ASMas).ThisiswhythistimetheconferenceiscalledMulti- Conference CAEPIA, as a sign of the strong tie between all Spanish artificial intelligence (AI) researchers. Moreover, this year CAEPIA was held within the IV Spanish Congress on Informatics (CEDI 2013). CAEPIAisaforumopentoworldwideresearcherstopresentanddiscusstheir last scientific and technological advances in AI. Its main aims are to facilitate the dissemination of new ideas and experiences, to strengthen the links among the different research groups, and to help spread new developments to society. All perspectives –theory, methodology, and applications– are welcome. Apartfromthepresentationoftechnicalfullpapers,thescientificprogramof CAEPIA2013includedtwoinvitedlectures,aDoctoralConsortiumand,forthe first time, a special session on outstanding recent papers (Key Works) already published in journals or forums of renowned reputation. With the permanent goalofmaking CAEPIAa high-qualityconference, and followingthemodelofcurrentdemandingAIconferences,theCAEPIAProgram Chairs organized the review process as follows. The Scientific Committee was structured in two levels. At the first level the AI knowledge was distributed in 11 areas and a Track Chair was assigned for each one. These Track Chairs are well-knownmembers of the AI community affiliated to Spanish universities and research centers. At the second level there was a ProgramCommittee with 116 members(37non-Spanishinstitutions). Allpaperswerecarefullypeer-reviewed, sometimeswiththesupportofadditionalreviewers.Therewere19additionalre- viewers(eightnon-Spanishinstitutions).Thereviewersjudgedtheoverallquality of the submitted papers, together with their originality and novelty, technical correctness,awarenessofrelatedwork,andqualityofpresentation.Thereviewers stated their confidence in the subject area in addition to detailed written com- ments. Eachpaper was assignedto at leastthree ProgramCommittee members who made the reviews(following the double-blind model), and to a TrackChair whosupervisedthesereviews.Onthe basisofthe reviews,the TrackChairsrec- VI Preface ommended paper acceptance or rejection to the CAEPIA ProgramChairs, who madethefinaldecisions.TheCAEPIAProgramChairschosetheBestCAEPIA Paper and the Best Reviewer, both awards acknowledgedby AEPIA. CAEPIA received66 submissions. Authors were requestedto mark their pa- per as candidate to be published in the LNAI volume. Out of the 66 submis- sions,48hadthis mark.Afterthe reviewprocess,27outofthesemarkedpapers were accepted for oral presentation and publication in this volume. Also, there weresubmissionsfor this volumefromthe otherassociatedconferences:17from MAEB2013(sixaccepted),10fromLFSC(fouraccepted),eightfromTAMIDA 2013 (two accepted), one from FINO 2013 (0 accepted) and two from ASMas (one accepted). These papers were reviewed under the same process and Scien- tific Committee as the previous CAEPIA papers. The Program Chairs of these conferences and the Chairs of the most related CAEPIA track also contributed to the review process. As a result, this volume contains 40 papers, each pre- sented in a 20-minute oral presentation during the conference. The papers were organized according to their topics. The two distinguished invited speakers were Francisco Herrera (ECCAI Fel- low,UniversityofGranada,Spain)andTomHeskes(Editor-in-Chiefofthescien- tific journal Neurocomputing, Radboud UniversityNijmegen, The Netherlands). FranciscoHerrerapresentedthemostrelevantaspectsofbigdata,thecharacter- istics of current libraries, and the challenges in the developmentof new scalable algorithms. Tom Heskes showed how Bayesian machine learning techniques can lead to a novel paradigm for brain–computer interfaces, the reconstruction of images based on fMRI activation, and network analysis from diffusion tensor imaging. The Doctoral Consortiumwas specially designed for the interactionbetween PhDstudentsandseniorresearchers.Ascientificpanelof12Spanishprofessorsin AIinteractedorallywiththestudentsontheirplansandpreliminaryresults.The Doctoral Consortium was a joint activity with all the conferences coordinated with CAEPIA, receiving 29 submissions. The Campus de Excelencia BioTICs ofthe GranadaUniversity sponsoredthe bestPhD workwith the GENIL prize, whereas AEPIA granted the next two best PhD proposals. The session on Key Works, also jointly held with the other five conferences, had 14 submissions. Recent works published in journals or forums of renown reputationduringtheperiod2011-2013wereallowedsoastospreadthemamong a wide audience from the AI community. Three senior members shaped the Selection Committee. The editors would like to thank everyone who contributed to the Multi- Conference CAEPIA 2013: the authors of the papers, the members of the Sci- entific Committee together with the additional reviewers, the invited speakers, andtheDoctoralConsortiumandKeyWorkssessionorganizers.Thanksarealso due to Luis Guerra, who designedthe website of the CAEPIA conference, man- aged the free EasyChair conference web system (http://www.easychair.org/), and compiled this volume. Final thanks go to the Organizing Committee (that Preface VII of CEDI included), the Complutense and Technical Universities of Madrid, the Springer team, our sponsors, and AEPIA for their support.
