Precision & Recall

Key metrics in pattern recognition and classification, measuring the accuracy and comprehensiveness of a model’s performance. Precision quantifies the proportion of relevant instances among the retrieved instances, highlighting the model’s accuracy in selecting relevant items. Recall, on the other hand, assesses the ratio of correctly identified relevant instances to the total number of actual relevant instances, indicating the model’s ability to capture all pertinent items. Both metrics rely on an understanding of relevance, serving as crucial indicators for evaluating the effectiveness of a model in identifying and retrieving relevant information. Optimizing both precision and recall is essential for achieving a balance between accuracy and completeness in search and classification tasks.
