Morphogenesis origins of patterns and shapes by Paul Bourgine ( )
10 editions published in 2011 in English and held by 359 WorldCat member libraries worldwide
What are the relations between the shape of a system of cities and that of fish school? Which events should happen in a cell in order that it participates to one of the finger of our hands? How to interpret the shape of a sand dune? This collective book written for the non-specialist addresses these questions and more generally, the fundamental issue of the emergence of forms and patterns in physical and living systems. It is a single book gathering the different aspects of morphogenesis and approaches developed in different disciplines on shape and pattern formation. Relying on the seminal works of D'Arcy Thompson, Alan Turing and René Thom, it confronts major examples like plant growth and shape, intra-cellular organization, evolution of living forms or motifs generated by crystals. A book essential to understand universal principles at work in the shapes and patterns surrounding us but also to avoid spurious analogies

Cognitive economics : an interdisciplinary approach by Paul Bourgine ( Book )
8 editions published between 2003 and 2004 in English and held by 157 WorldCat member libraries worldwide
The social sciences study knowing subjects and their interactions. A "cognitive turn", based on cognitive science, has the potential to enrich these sciences considerably. Cognitive economics belongs within this movement of the social sciences. It aims to take into account the cognitive processes of individuals in economic theory, both on the level of the agent and on the level of their dynamic interactions and the resulting collective phenomena. This book is a result of a three-year experiment in interdisciplinary cooperation in cognitive economics. It has the advantage of reflecting joint, long-term work between economists, specialists in cognitive science, physicists, mathematicians and computer scientists. The main aim of the book is to enable any researcher interested in cognitive economics, whatever his or her original speciality, to grasp essential landmarks in this emerging field. Part I of the book provides disciplinary bases, Part II is focused on advanced research

Evolutionary microeconomics by Jacques Lesourne ( Book )
7 editions published between 2006 and 2010 in English and held by 23 WorldCat member libraries worldwide
Classical microeconomics is intended to explain how a price system is able to coordinate the economic agents. But even if it can be extended to incomplete information and externalities, it remains grounded on very heroic assumptions. Agents are endowed with a very strong rationality, equilibrium is stated without a concrete process to achieve it, market is the unique institution considered. "Evolutionary Microeconomics" is aimed at bypassing these limitations by considering a dynamic approach, however not biologically oriented. Agents have local information and bounded rationality, they are involved in explicit processes of interactions through time, various institutions sustain the market or substitute to it. It explains then some phenomena hardly explained by classical microeconomics: dispersion of prices, variety of industrial structures, financial bubbles

Nécessité des modèles en sciences cognitives de la modélisation à la mise en parangon by Pierre Daignault ( Book )
2 editions published in 1998 in French and held by 4 WorldCat member libraries worldwide
LA LIGNE DIRECTRICE PRINCIPALE DE CE TRAVAIL EST LA MODELISATION EN SCIENCES COGNITIVES. NOUS LA PRESENTONS DU POINT DE VUE D'UN MODELISATEUR INSPIRE DE LA DEMARCHE DE LA PHYSIQUE ET QUI CONSTATE QUE LA SOPHISTICATION PROGRESSIVE ET NECESSAIRE DES MODELES POUR RENDRE COMPTE DES PHENOMENES QUI NOUS INTERESSENT ENTRAINE DES MODIFICATIONS DANS LA PRATIQUE MEME DE LA MODELISATION. EN INTRODUCTION NOUS EXPLIQUONS COMMENT, A PARTIR DE NOS TRAVAUX SUR L'APPRENTISSAGE PAR RENFORCEMENT, NOUS EN SOMMES VENUS A NOUS POSER DES QUESTIONS SUR LA MODELISATION ALORS QU'A PRIORI LE TRAVAIL DU MODELISATEUR EST DE MODELISER ET NON PAS DE REFLECHIR SUR LA MODELISATION ELLE-MEME. DANS UN PREMIER CHAPITRE NOUS PRECISONS, A PARTIR DU PARCOURS DE VON NEUMANN, LES FONDEMENTS HISTORIQUES DONT SONT ISSUES LES CONCEPTIONS METHODOLOGIQUES PRATIQUEES EN SCIENCES COGNITIVES. DANS UN DEUXIEME CHAPITRE NOUS ANALYSONS LA CONCEPTION DES PROCESSUS EN SCIENCES COGNITIVES QUI FONDE L'UNITE DE CES SCIENCES ET PERMET DE PRECISER CERTAINS CHOIX

Mise au point automatique et interactive de modeles by Pascal Rivière ( Book )
1 edition published in 1994 in French and held by 1 WorldCat member library worldwide
LE BUT DE CE TRAVAIL EST DE FORMALISER ET D'AUTOMATISER UNE ETAPE PEU ETUDIEE DU PROCESSUS DE MODELISATION: L'AJUSTEMENT DU MODELE AUX CONNAISSANCES OU AUX A PRIORI DU MODELISATEUR ; CECI RESULTE D'UN MECANISME DE VALIDATION SUBJECTIF, CE QUI N'A DE SENS QUE POUR DES MODELES STATISTIQUES. DANS UNE PREMIERE PARTIE, NOUS EXPLICITONS DONC LA NOTION DE MODELE, SON INTERET, AINSI QUE LA FACON DE CONSTRUIRE ET DE REMETTRE EN QUESTION CET OBJET MATHEMATIQUE. LE CAS DES MODELES ECONOMIQUES EST ENSUITE ETUDIE, L'ACCENT ETANT MIS PLUS PARTICULIEREMENT SUR LE CALAGE DE CES MODELES, SA JUSTIFICATION, ET SES TENANTS ET ABOUTISSANTS ; UNE FORMULATION MATHEMATIQUE GENERALE DU META-PROBLEME DU CALAGE EST PROPOSEE. DANS UNE TROISIEME PARTIE, NOUS EN PRESENTONS UNE APPROCHE DIFFERENTE, CONSISTANT A SIMULER LE MODELISATEUR LORSQU'IL AJUSTE SON MODELE. POUR REALISER CELA, UN SYSTEME EXPERT A BASE DE REGLES A ETE ECRIT, SUR LA BASE D'ENTRETIENS AVEC DES SPECIALISTES DE LA MODELISATION MACROECONOMIQUE. MAIS LA METHODE DE MISE AU POINT LA PLUS EFFICACE, NON LIMITEE A L'ECONOMIE, EST CELLE QUI REPRESENTE LES ANTAGONISMES ENTRE LES DIVERSES CONNAISSANCES PAR DES FORCES DE RAPPEL, QUI EVENTUELLEMENT S'OPPOSENT. CETTE TECHNIQUE, APPLIQUEE AUJOURD'HUI A L'INSEE, OBLIGE LE MODELISATEUR A AFFICHER SES CONNAISSANCES, ET LUI PERMET DE DETECTER SES PROPRES CONTRADICTIONS AFIN QU'IL PUISSE REFORMULER SON PROBLEME ; CETTE PHASE INTERACTIVE DE LA MISE AU POINT PRECEDE UNE PHASE AUTOMATIQUE, PUISQU'A CONNAISSANCES FIXEES, L'AJUSTEMENT DE MODELE EST RAMENE A UN PROBLEME BIEN POSE

Le dilemme entre exploration et exploitation dans l'apprentissage par renforcement : optimisation adaptative des modeles de decision multi-etats by NICOLAS MEULEAU ( Book )
1 edition published in 1996 in French and held by 1 WorldCat member library worldwide
CETTE THESE S'INTERESSE AU DILEMME ENTRE L'EXPLORATION ET L'EXPLOITATION TEL QU'IL SE POSE DANS LES ALGORITHMES DE L'APPRENTISSAGE PAR RENFORCEMENT, C'EST-A-DIRE AU PROBLEME DU CHOIX DE L'ACTION LORS DE L'OPTIMISATION ADAPTATIVE DES MODELES DE DECISION MULTI-ETATS. NOUS NOUS FOCALISONS SUR LE CAS DES PROCESSUS DE DECISION MARKOVIENS. L'APPRENTISSAGE PAR RENFORCEMENT SE CARACTERISE PAR L'UTILISATION DE SOLUTIONS APPROCHEES. NOTRE RECHERCHE VISE A AMELIORER CES SOLUTIONS. DANS CE BUT, NOUS NOUS INSPIRONS DU TRAVAIL D'AUTRES COMMUNAUTES COMME L'AIDE A LA DECISION ET LA COMMANDE OPTIMALE ADAPTATIVE. AU TRAVERS DE LA PRESENTATION DES RESULTATS DES DIFFERENTS DOMAINES, NOUS SOULIGNONS LES TROIS DIFFICULTES SUIVANTES: 1 L'IMPOSSIBILITE D'OBTENIR DES CERTITUDES SUR LES PARAMETRES INCONNUS AVANT UN NOMBRE INFINI D'EXPERIMENTATIONS, ET DONC LA NECESSITE DE CHOISIR ENTRE NE JAMAIS ABANDONNER COMPLETEMENT L'EXPLORATION ET PRENDRE LE RISQUE DE SE FOCALISER SUR UNE SOLUTION SOUS-OPTIMALE ; 2 L'INSUFFISANCE DES RAISONNEMENTS A L'ECHELLE LOCALE, C'EST-A-DIRE LA NECESSITE DE SAVOIR ANTICIPER, DEPUIS UN ETAT DU MODELE, LES OBSERVATIONS QUI POURRONT ETRE FAITES DANS LES AUTRES ETATS ; 3 LA SENSIBILITE DES ALGORITHMES A LA REPRESENTATION DU PROBLEME UTILISEE. BEAUCOUP D'ALGORITHMES DE L'APPRENTISSAGE PAR RENFORCEMENT UTILISENT UNE APPROCHE DISTRIBUEE QUI CONSISTE A REPRESENTER LE PROBLEME DE L'APPRENTISSAGE D'UN MODELE MULTI-ETATS, PAR UN ENSEMBLE DE PROBLEMES A UN ETAT APPELES PROBLEMES DE BANDIT. NOUS SOULIGNONS QUELQUES LIMITES DE CETTE DEMARCHE, ET EN PARTICULIER LE FAIT QU'ELLE N'EST PAS SATISFAISANTE AU REGARD DU DEUXIEME DES POINTS ENONCES CI-DESSUS. NOUS PROPOSONS DE CONTOURNER CELA EN INTRODUISANT UN MECANISME DE RETROPROPAGATION DE L'INCERTITUDE MESUREE, DE MANIERE A SIMULER UN RAISONNEMENT A L'ECHELLE GLOBALE. CELA PERMET DE CONCEVOIR DES ALGORITHMES SATISFAISANT AU REGARD DES TROIS DIFFICULTES SOULIGNEES PRECEDEMMENT. DES SIMULATIONS NUMERIQUES SONT MENEES DE MANIERE A METTRE EN EVIDENCE L'INTERET ET LES LIMITES DES DIFFERENTES PROPOSITIONS. POUR CELA, NOUS UTILISONS UN ENSEMBLE DE PROBLEMES DE DECISION MARKOVIENS EXTRAITS DE LA LITTERATURE, OU CONSTRUIT DE MANIERE A COUVRIR LE PLUS LARGEMENT LA GAMME DES PROBLEMES POSSIBLES. LA CONTRIBUTION DE CETTE THESE CONSISTE DONC EN: LA SYNTHESE DES DIFFERENTES APPROCHES DU PROBLEME, L'ETUDE DES LIMITES DES ARCHITECTURES DISTRIBUEES DE L'APPRENTISSAGE PAR RENFORCEMENT, LA PROPOSITION D'ALGORITHMES UTILISANT LA RETROPROPAGATION DE L'INCERTITUDE, LES RESULTATS DES SIMULATIONS NUMERIQUES
