Nearest Neighbor Explanation
Interpretability technique that explains a model's decision by identifying and presenting the training examples closest to the instance to be explained.
Representative Instance
Typical or archetypal example of a class or concept, chosen for its ability to capture the essential characteristics of the group to which it belongs.
Exemplar-Based Explanation
Explanation method that uses concrete and specific examples (exemplars) to justify and clarify the predictions of a machine learning model.
K-Nearest Prototypes
Variant of k-nearest neighbors using pre-computed prototypes instead of all training instances to improve efficiency and interpretability.
Critical Prototype
Particularly influential prototype in a model's decision process, often located near decision boundaries between different classes.
Prototype Distance Metric
Similarity or dissimilarity measurement function specifically designed to quantify the distance between a given instance and reference prototypes.
Prototype Matching
Process of comparing a new instance with the available set of prototypes to determine the most similar prototype and explain the corresponding decision.
Prototype-Based Model Interpretation
Model interpretation approach that structures explanations around comparisons with pre-defined prototypes, making decisions more intuitive for users.
Prototype Weighting
Technique d'assignation de poids aux différents prototypes pour refléter leur importance relative dans le processus de décision et d'explication du modèle.
Prototype Space Partitioning
Division de l'espace des prototypes en régions distinctes, chacune associée à un prototype particulier, pour structurer l'explication des prédictions selon la proximité spatiale.
Prototype Similarity Function
Fonction mathématique qui calcule un score de similarité entre une instance et un prototype, servant de base aux explications par comparaison dans les systèmes interprétables.
Prototype Coverage
Mesure évaluant dans quelle mesure l'ensemble des prototypes couvre adéquatement l'espace des données d'entrée pour garantir des explications complètes et pertinentes.
Prototype Quality Metric
Indicateur quantitatif évaluant la qualité d'un prototype selon des critères tels que la représentativité, la compacité et la capacité discriminante dans l'espace des caractéristiques.
