Book Description
LE TRAVAIL PRESENTE DANS CETTE THESE S'INSCRIT DANS UN SYSTEME COMPLET DE RECONNAISSANCE DE L'ECRITURE MANUSCRITE CURSIVE. NOUS AVONS APPLIQUE NOS RECHERCHES AU CAS PARTICULIER DE LA RECONNAISSANCE DE CHEQUES BANCAIRES. CE TRAITEMENT GLOBAL D'UN TEXTE MANUSCRIT SE DECOMPOSE EN PLUSIEURS ETAPES QUI SONT: L'EXTRACTION DU TRACE, LA SEGMENTATION EN PHRASES, EN MOTS, EN GRAPHEMES, SUIVI D'UNE RECONNAISSANCE DE GRAPHEMES, PUIS DE MOTS, ENFIN DE PHRASES. NOTRE ETUDE PORTE SUR LA RECONNAISSANCE DE GRAPHEMES. LES PARTICULARITES DE NOTRE SOLUTION CONCERNENT LES POINTS SUIVANTS. -L'OBTENTION DES FORMES CARACTERISTIQUES SE FAIT EN RECHERCHANT SUR L'IMAGE LES TRAITS DANS LES QUATRE DIRECTIONS HORIZONTALES, VERTICALES, +45#-, -45#-, ON EN DEDUIT LES PRIMITIVES QUI, DANS NOTRE CAS, SONT AU NOMBRE DE SIX: LES BOUCLES, LES COURBES, LES SEGMENTS, LES SEGMENTS AYANT UNE EXTREMITE LIBRE, LES POINTS SINGULIERS ET LA NOTION D'ASCENDANT/DESCENDANT. UNE PRIMITIVE EST REPEREE PAR SES COORDONNEES DANS L'IMAGE RAPPORTEE A UN QUADRILLAGE 5X5 ET PAR SA TAILLE. -L'APPRENTISSAGE SE FAIT EN ACCUMULANT LES EXEMPLES DANS UNE STRUCTURE, OU TABLEAU APPELE GABARIT. ON CONSTRUIT UN GABARIT PAR CLASSE A RECONNAITRE ET PAR PRIMITIVE. -LA RECONNAISSANCE PAR GABARITS CONSISTE A AFFECTER A CHACUNE DES CLASSES POUR CHACUNE DES PRIMITIVES, UN SCORE. LA FONCTION DE RECONNAISSANCE ASSOCIEE A UNE PRIMITIVE EST APPELEE OPERATEUR. -LA COMBINAISON DES OPERATEURS TRANSFORME LES LISTES DE REPONSES ORDONNEES SUIVANT LEUR PROBABILITES EN UNE LISTE UNIQUE. -LA RECOMBINAISON A POUR BUT DE REARRANGER, AUTREMENT DIT DE CORRIGER, LA LISTE DE REPONSES PRECEDENTE. POUR CELA, UN SECOND APPRENTISSAGE EST EFFECTUE SUR UNE AUTRE BASE D'EXEMPLES DITE BASE D'AJUSTEMENT. CET APPRENTISSAGE DONNE UNE REPRESENTATION DU COMPORTEMENT DU SYSTEME. LA RECOMBINAISON SE BASE SUR LA CONNAISSANCE A PRIORI APPORTEE PAR LA PREMIERE RECONNAISSANCE POUR EFFECTUER UNE SECONDE RECONNAISSANCE CETTE FOIS DE TYPE GUIDEE PAR LES MODELES DANS LAQUELLE LES OPERATEURS A PRENDRE EN COMPTE SONT CHOISIS EN FONCTION DE CET A PRIORI ET DONC DIFFERENTS DANS CHAQUE CAS. LES RESULTATS OBTENUS SONT DE 49% POUR LA PREMIERE REPONSE, 67% POUR LES DEUX PREMIERES ET 88% POUR LES CINQ PREMIERES. LES COMPARAISONS AVEC D'AUTRES SYSTEMES SONT DIFFICILES, CEPENDANT SANS PROPOSER LA METHODE LA PLUS PERFORMANTE NOTRE TECHNIQUE PRESENTE DES RESULTATS TRES SATISFAISANTS PERMETTANT UNE INTERPRETATION DU COMPORTEMENT DU SYSTEME EN MANIPULANT DES IDEES ET DES REPRESENTATIONS SIMPLES A METTRE EN UVRE, PEU ENCOMBRANTES EN MEMOIRE, ET RAPIDES A L'EXECUTION

Book Description
Once treated as the absence of knowledge, ignorance today has become a highly influential topic in its own right, commanding growing attention across the natural and social sciences where a wide range of scholars have begun to explore the social life and political issues involved in the distribution and strategic use of not knowing. The field is growing fast and this handbook reflects this interdisciplinary field of study by drawing contributions from economics, sociology, history, philosophy, cultural studies, anthropology, feminist studies, and related fields in order to serve as a seminal guide to the political, legal and social uses of ignorance in social and political life.

Book Description
This volume appears now finally in English, sixty years after the death of its author, Lucien Tesnière. It has been translated from the French original into German, Spanish, Italian, and Russian, and now at long last into English as well. The volume contains a comprehensive approach to the syntax of natural languages, an approach that is foundational for an entire stream in the modern study of syntax and grammar. This stream is known today as dependency grammar (DG). Drawing examples from dozens of languages, many of which he was proficient in, Tesnière presents insightful analyses of numerous phenomena of syntax. Among the highlights are the concepts of valency and head-initial vs. head-final languages. These concepts are now taken for granted by most modern theories of syntax, even by phrase structure grammars, which represent, in a sense, the opposite sort of approach to syntax from what Tesnière was advocating. Now Open Access as part of the Knowledge Unlatched 2017 Backlist Collection.

Book Description
Cordial Cold War examines cultural entanglements, in various forms, between two distant yet interconnected sites of the Cold War—India and the German Democratic Republic (GDR). Focusing on theatre performances, film festivals, newsreels, travel literature, radio broadcasting, cartography and art as sites of engagement, the chapters spotlight spaces of interaction that emerged in spite of, and within, the ambits of Cold War constraints. The inter-disciplinary collection sheds light on the variegated nature of translocal cultural entanglements, at work even before the GDR was officially recognized as a sovereign state by India in 1972. By foregrounding the role of actors, their practices and the sites of their entanglement, the contributions show how creative energies were mobilized to forge zones of friendship, mutual interest and envisioned solidarities. This volume situates actors from the Global South as mutual co-shapers of the cultural Cold War, therein shifting its Euro-American and Soviet epicenters to Non-Aligned India. Going beyond official state channels of international political dialogue, it locates cordiality in the micro-histories and everyday experiences of interpersonal engagements, bringing to focus a hitherto underexplored chapter of India–Germany entanglements.

Book Description
The ink and stylus tablets discovered at the Roman fort of Vindolanda are a unique historical resource but are extremely difficult to read. This book details the development of what appears to be the first system constructed to aid experts in the process of reading an ancient document, exploring the use of techniques from Artificial Intelligence.
