Questions & Step-by-Step Solutions

In a binary classification problem, what does a high recall indicate?
  • Step 1: Understand what binary classification means. It involves categorizing data into two groups: positive and negative.
  • Step 2: Know what recall is. Recall measures how many actual positive cases were correctly identified by the model.
  • Step 3: Realize that a high recall means the model is good at finding positive cases.
  • Step 4: Conclude that a high recall indicates that the model misses very few actual positive cases.
  • Recall – Recall is a metric that measures the ability of a model to identify all relevant instances, specifically the proportion of true positives out of the total actual positives.
