The aim of the seriesistomakeavailableaplatformforthepublicationofbooksonallaspectsof single and multi-disciplinary research on these themes in order to make the latest resultsavailableinareadily-accessibleform.Volumesoninterdisciplinaryresearch combining two or more of these areas is particularly sought. The series covers systems and paradigms that employ knowledge and intelligence in a broad sense. Its scope is systems having embedded knowledge and intelligence, which may be applied to the solution of world problems in industry, the environment and the community. It also focusses on the knowledge-transfer methodologies and innovation strategies employed to make this happen effectively. The combination of intelligent systems tools and a broad range of applications introduces a need for a synergy of disciplines from science, technology, business and the humanities. The series will include conference proceedings, edited collections, monographs, handbooks, reference books, and other relevant types of book in areas of science and technology where smart systems and technologies can offer innovative solutions.

The aim is to create hybrid methods that benefit from each of their components. It is generally believed that complex problems can be easily solved with hybrid methods. By “hybrid,” we mean any kind of combined use (either tight or loose) of distinct intelligent methods toward solving a problem, eitherspecificorgeneral.Inthissense,itisusedassynonymouswith“integrated.” Some of the existing efforts try to make hybrids of what are called soft com- putingmethods(fuzzylogic,neuralnetworks,andgeneticalgorithms)eitheramong themselves or with more traditional AI methods, such as logic and rules. Another stream of efforts integrates case-based reasoning or machine learning with soft computing or traditional AI methods. Yet another integrates agent-based approa- cheswithlogicandnon-symbolicapproaches.Someofthecombinationshavebeen quite important and more extensively used, like neuro-symbolic methods, neuro-fuzzy methods, and methods combining rule-based and case-based reason- ing.However,thereareothercombinationsthatarestillunderinvestigation,suchas those related to the Semantic Web and Big Data areas. For example, the recently emergeddeeplearningarchitecturesormethodsarealsohybridbynature.Insome cases,integrationsarebasedonfirstprinciples,creatinghybridmodels,whereasin othercasestheyarecreatedinthecontextofsolvingproblemsleadingtosystemsor applications.

CIMA 2016 was held in conjunction with the 22nd EuropeanConferenceonArtificialIntelligence(ECAI2016),August30,2016,The Hague, Holland. Papers went through a peer review process by the CIMA-16 program committee members.

Teppan and Gerhard Friedrich ix Deep Learning Approaches for Facial Emotion Recognition: A Case Study on FER-2013 Panagiotis Giannopoulos, Isidoros Perikos and Ioannis Hatzilygeroudis Abstract Emotions constitute an innate and important aspect of human behavior that colors the way of human communication. The accurate analysis and interpre- tation of the emotional content of human facial expressions is essential for the deeper understanding of human behavior. Although a human can detect and interpretfacesandfacialexpressionsnaturally,withlittleornoeffort,accurateand robust facial expression recognition by computer systems is still a great challenge. The analysis of human face characteristics and the recognition of its emotional statesareconsideredtobeverychallenginganddifficulttasks.Themaindifficulties comefromthenon-uniformnatureofhumanfaceandvariationsinconditionssuch as lighting, shadows, facial pose and orientation. Deep learning approaches have been examined as a stream of methods to achieve robustness and provide the necessary scalability on new type of data. In this work, we examine the perfor- manceoftwoknowndeeplearningapproaches(GoogLeNetandAlexNet)onfacial expression recognition, more specifically the recognition of the existence of emo- tional content, and on the recognition of the exact emotional content of facial expressions. The results collected from the study are quite interesting. ⋅ ⋅ Keywords Affective computing Facial emotion recognition Deep ⋅ ⋅ ⋅ learning Convolutional neural networks GoogLeNet Alexnet P.Giannopoulos(✉) ⋅ I.Perikos ⋅ I.Hatzilygeroudis DepartmentofComputerEngineeringandInformatics, UniversityofPatras,Patras,Greece e-mail:[email protected] I.Perikos e-mail:[email protected] I.Hatzilygeroudis e-mail:[email protected] I.Perikos TechnologicalEducationalInstituteofWesternGreece,Patras,Greece ©SpringerInternationalPublishingAG2018 1 I.HatzilygeroudisandV.Palade(eds.),AdvancesinHybridization ofIntelligentMethods,SmartInnovation,SystemsandTechnologies85, https://doi.org/10.1007/978-3-319-66790-4_1
