Editorial
Methods and applications of artificial and computational intelligence
This Special Issue is based on the expanded versions of selectedpapers presented during 11th MICAI, Mexican International Con-ference on Artificial Intelligence, October 27 – November 4, 2012,San Luis Potosí, Mexico. MICAI conferences are organized annuallyby the Mexican Society for Artificial Intelligence (SMIA). This Spe-cial Issue starts with the Invited Paper written by Francisco J. Can-tu-Ortiz, Past President of SMIA (1997–2000) and Conference Chairof the 1st MICAI, organized in Acapulco, Mexico in 2000. In his pa-per ‘‘Advancing artificial intelligence research and dissemina-tion through conference series: benchmark, scientific impactand the MICAI experience’’ he presents an overview, analysisand benchmark of the best-known artificial intelligence confer-ences, including MICAI, IJCAI, AAAI, ECAI, IBERAMIA, AAJCAI andPRICAI. Conference trends and future developments are alsoexplained.
Other papers of the Special Issue can be joined in several groupsaccording to the application areas or proposed methods: imageprocessing, medical applications, speech recognition and naturallanguage processing, global optimization with adaptive mutationstrategy, multi-criteria decision making and support vectors ma-chines, analysis of purchasing behavior of equipment manufactur-ers, workflow verification and intruder detection.
During the last 2-3 years, the interest in RGB-D sensors anddepth imaging technology is dramatically increasing due to thewide range of industrial applications. The paper ‘‘Evolutionaryjoint selection to improve human action recognition withRGB-D devices’’ proposes an evolutionary algorithm to improvehuman action recognition with RGB-D cameras. The proposedreduction of the size of the feature vector used in the descriptionof human skeletons and actions by the evolutionary algorithmhas an impact on the processing rate, since the recognition is per-formed faster. This will allow the development of more complexrecognition algorithms and their application in real-time.
The paper ‘‘A novel evidence based model for detecting dan-gerous situations in level crossing environments’’ describes thestructure of a video surveillance system able to detect, recognizeand evaluate potentially dangerous situations in level crossingenvironments. The proposed methodology includes different mod-els and methods of moving objects detection and separation, mul-ti-object tracking, trajectory prediction and evaluation ofdangerous situations at level crossings.
The authors of the paper ‘‘A methodology for the characteriza-tion of flow conductivity through the identification of commu-nities in samples of fractured rocks’’ propose the novel approachto characterization of possible flow conductivity in naturally frac-tured reservoir based on analysis of fracture networks obtainedfrom rock images. The proposed methodology transforms the frac-ture image into a graph and applies the graph analysis algorithmsstudied in social and communication networks analysis.

The paper ‘‘Two-steps learning of fuzzy cognitive maps forprediction and knowledge discovery on the HIV-1 drug resis-tance’’ proposes a model based on fuzzy cognitive maps for analyz-ing the behavior of the HIV-1 protease protein. A two stepslearning algorithm using swarm intelligence for optimizing themodeling parameters is introduced.
The paper ‘‘Evolutionary computation in the identification ofrisk factors. Case of TRALI’’ presents an evolutionary algorithm fordetermining factors associated with transfusion related acute lunginjury (TRALI). This algorithm is combined with the pattern recog-nition technique based on the concept of testor. A strategy for thetreatment of patients that should be transfused is proposed.
The authors of the paper ‘‘Evolutionary approach for integra-tion of multiple pronunciation patterns for enhancement ofdysarthric speech recognition’’ propose the method of enhance-ment of dysarthric speech recognition based on integration of mul-tiple pronunciation patterns. This integration is performed byweighting the responses of an Automatic Speech Recognition sys-tem for different language model restrictions. The weights are esti-mated by a genetic algorithm that also optimizes the structure ofthe implementation technique based on discrete hidden Markovmodels.
The paper ‘‘Syntactic N-grams as machine learning featuresfor natural language processing’’ describes a novel idea in naturallanguage processing consisting in construction of n-grams on syn-tactic trees. It allows to introduce the syntactic information intomachine learning methods. The results of the application of syntac-tic n-grams to the task of the automatic authorship attribution arepresented and it is shown that syntactic n-grams have better per-formance than traditional n-grams.
The authors of the paper ‘‘Minimizer of the reconstruction er-ror for multi-class document categorization’’ introduce and val-idate an approach for single-label multi-class documentcategorization based on text content features. The proposed ap-proach uses the statistical property of principal component analy-sis, which minimizes the reconstruction error of the trainingdocuments used to compute a low-rank category transformationmatrix.
The paper ‘‘Multi-criteria selection of an Air Quality Modelconfiguration based on quantitative and linguistic evaluations’’studies the problem of selecting configuration of complex multi-parametric computational Air Quality Model (AQM) which simu-lates the atmospheric transformations of gases and aerosols emit-ted into the atmosphere. A method for selecting Pareto optimalconfigurations of AQM suitable for future air quality studies is pro-posed when several traditional measures and expert evaluations ofperformance of the model are used as criteria.
The paper ‘‘An adaptive single-point algorithm for globalnumerical optimization’’ describes a novel algorithm for global

numerical optimization, called Simple Adaptive Climbing (SAC).SAC is a simple efficient single-point approach with adaptive muta-tion process that shares many similarities with optimization heu-ristics such as Random Walk, Gradient Descent, Hill-Climbingand Differential Evolution. Test results on 15 well-known uncon-strained problems confirm that SAC is competitive against state-of-the-art approaches such as micro-Particle Swarm optimization,CMA-ES or Simple Adaptive Differential Evolution.
The paper ‘‘Quadratic optimization fine tuning for the sup-port vector machines learning phase’’ presents a comparativeanalysis of specific mathematical programming implementationtechniques of the quadratic optimization problem based on thesupport vector machines learning process. The authors proposeseveral optimization strategies of general decomposition of thequadratic optimization problem to treat large-scale applications.
The authors of the paper ‘‘Characterization and analysis ofsales data for the semiconductor market: an expert system ap-proach’’ propose the methodology for predicting purchasingbehavior in the semiconductor market. Chip purchasing policiesof the Original Equipment Manufacturers (OEMs) of laptop com-puters are characterized by similarity measures and probabilisticrules extracted from data of products bought by the OEMs in thesemiconductor market. The characterization of the purchasingbehavior of the OEMs involves multiple overlapping productslaunched into the market over time.
The authors of the paper ‘‘On verification of nested workflowswith extra constraints: from theory to practice’’ formalize theproblem of workflow verifications as the problem of verifying thatthere exists a feasible process for each task in the workflow. Thisproblem is tractable for nested workflows, e.g. for workflows ofbusiness and manufacturing processes, with a hierarchical struc-ture similar to hierarchical task networks in planning. NP com-pleteness of the workflow verification problem is studied. Thepaper presents a workflow verification algorithm for nested work-
flows with extra constraints that is based on constraint satisfactiontechniques and exploits an incremental temporal reasoningalgorithm.
The paper ‘‘The Windows-Users and -Intruder simulationsLogs dataset (WUIL): An experimental framework for masquer-ade detection mechanisms’’ introduces a new masquerade data-set, called WUIL, which, unlike existing datasets, involves morefaithful masquerade attempts. WUIL exploits the hypothesis thatthe way in which a user navigates file system structure can neatlyseparate a masquerade attack. The authors argue that this ap-proach, based on file system navigation, provides a richer means,and at a higher-level of abstraction, for building novel models formasquerade detection.
