AI Model Evaluation

Introduction

This page provides an overview of AI model evaluation techniques. Understanding these techniques is crucial for selecting the best model for a given task.

Different evaluation metrics assess different aspects of model performance. These metrics are vital for monitoring and improving models.

Evaluation Metrics

• Accuracy: The percentage of correct predictions.
• Precision: Measures the proportion of correctly identified positive cases among all instances predicted as positive.
• Recall: Measures the proportion of correctly identified positive cases among all actual positive cases.
• F1-Score: The harmonic mean of precision and recall, providing a balanced measure.
• AUC-ROC: Area Under the Receiver Operating Characteristic curve.
• RMSE: Root Mean Squared Error.

How it Works

Various techniques are used to evaluate AI models, including:

• Cross-Validation: Dividing the data into multiple folds for unbiased performance assessment.
• Hold-Out Validation: A subset of data is held out for final evaluation.
• Test Data: A completely separate dataset used only for final, unbiased model evaluation.
• Benchmarking: Comparing performance against established models.
