Model Accuracy Calculator

Calculate ML model performance metrics

The Model Accuracy Calculator is an essential tool for data scientists and AI developers seeking to evaluate the performance of their machine learning models efficiently. By inputting your confusion matrix values—true positives, true negatives, false positives, and false negatives—you can quickly obtain critical performance metrics such as accuracy, precision, recall, and the F1 score. This calculator streamlines the process, allowing you to focus on enhancing your models rather than manually calculating metrics. What sets the Model Accuracy Calculator apart is its user-friendly interface which is designed to accommodate users of all skill levels, from beginners to experts. By providing instant outputs, the tool not only saves time but also ensures accuracy in your evaluations. Additionally, this free resource supports various model types, making it versatile for all your machine learning evaluation needs. Whether you’re conducting exploratory data analysis or optimizing your AI models for production, our calculator is here to assist and empower your data-driven decisions.

How it works

The result is derived through the following steps:

  1. total = inputs.truePositives + inputs.trueNegatives + inputs.falsePositives + inputs.falseNegatives
  2. accuracy = ((inputs.truePositives + inputs.trueNegatives) / total) * 100
  3. precision = inputs.truePositives / (inputs.truePositives + inputs.falsePositives) * 100
  4. recall = inputs.truePositives / (inputs.truePositives + inputs.falseNegatives) * 100
  5. f1Score = 2 * (precision * recall) / (precision + recall)
  6. specificity = inputs.trueNegatives / (inputs.trueNegatives + inputs.falsePositives) * 100
