conmatrix : Confusion Matrix # Data Imbalance # Evaluation # Weights & Biases

Objective

• Build a confusion matrix
• Assess performance of classification models.
• Resolve biases in a classification model
• Evaluate results of binary classification models using a confusion matrix.
• Use weighted classes to address class imbalances when training a model and evaluating the results.
• Review metrics to improve classification models.
• Mitigate performance issues from data imbalances.
• Calculate the very basic measurements used in the evaluation of classification models: TP, FP, TN, FN.
• Use the measurement aboves to calculate more meaningful metrics, such as:
  • Accuracy
  • Sensitivity/Recall
  • Specificity
  • Precision
  • False positive rate
