My ML Model Was 97% Confident Every Time — Here’s Why That Was Actually a Problem

📰 Medium · Machine Learning

Learn why a machine learning model's high confidence score can be a problem and how to identify and address it

intermediate Published 28 Apr 2026
Action Steps
  1. Evaluate your model's performance on a validation set to check for overconfidence
  2. Check for class imbalance in your dataset, which can lead to overly confident models
  3. Use techniques such as calibration plots and reliability diagrams to assess your model's confidence
  4. Regularly monitor your model's performance on new, unseen data to detect potential issues
  5. Consider using techniques such as uncertainty estimation and Bayesian methods to improve your model's confidence estimation
Who Needs to Know This

Data scientists and machine learning engineers can benefit from understanding the potential pitfalls of high confidence scores in their models, to ensure more accurate and reliable predictions

Key Insight

💡 High confidence scores in machine learning models can be a sign of overconfidence, which can lead to poor performance on new, unseen data
