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
