Reconnaissance gestuelleGesture recognition is a topic in computer science and language technology with the goal of interpreting human gestures via mathematical algorithms. It is a subdiscipline of computer vision. Gestures can originate from any bodily motion or state, but commonly originate from the face or hand. Focuses in the field include emotion recognition from face and hand gesture recognition since they are all expressions. Users can make simple gestures to control or interact with devices without physically touching them.
Model selectionModel selection is the task of selecting a model from among various candidates on the basis of performance criterion to choose the best one. In the context of learning, this may be the selection of a statistical model from a set of candidate models, given data. In the simplest cases, a pre-existing set of data is considered. However, the task can also involve the design of experiments such that the data collected is well-suited to the problem of model selection.
Traitement automatique du langage naturelLe traitement automatique du langage naturel (TALN), en anglais natural language processing ou NLP, est un domaine multidisciplinaire impliquant la linguistique, l'informatique et l'intelligence artificielle, qui vise à créer des outils de traitement du langage naturel pour diverses applications. Il ne doit pas être confondu avec la linguistique informatique, qui vise à comprendre les langues au moyen d'outils informatiques.
Group method of data handlingGroup method of data handling (GMDH) is a family of inductive algorithms for computer-based mathematical modeling of multi-parametric datasets that features fully automatic structural and parametric optimization of models. GMDH is used in such fields as data mining, knowledge discovery, prediction, complex systems modeling, optimization and pattern recognition. GMDH algorithms are characterized by inductive procedure that performs sorting-out of gradually complicated polynomial models and selecting the best solution by means of the external criterion.
Interface utilisateur vocaleUne interface utilisateur vocale ou IUV (ou VUI pour Vocal User Interface en anglais) rend possible l'interaction orale entre les humains et les ordinateurs. Un dispositif de commande vocale (ou VCD pour Voice Command Device) est un appareil doté d'une interface utilisateur vocale. Les ordinateurs équipés d'un tel dispositif utilisent généralement la reconnaissance vocale pour comprendre les mots énoncés par les humains et la synthèse vocale pour en produire.
