Encord Computer Vision Glossary

Debugging in machine learning (ML) refers to the process of identifying and fixing errors in an ML model. These errors, also known as bugs, can occur at various stages of the ML process, from data preparation and feature engineering to model training and deployment.",

How do you debug a computer vision model?

Debugging ML models can be a challenging task because the models are often complex and may involve many variables and parameters. Moreover, the errors in ML models may not always be immediately apparent and may only manifest themselves in the form of poor performance on unseen data.

There are several approaches to debugging ML models, including:

  • Visualizing the data: One of the first steps in debugging an ML model is to understand the data that the model is using. This can be done by visualizing the data using tools such as Matplotlib or seaborn.
  • Examining the model's performance: Another important step is to examine the model's performance on various metrics such as accuracy, precision, and recall. This can help identify any issues with the model's predictions and suggest areas for improvement.
  • Analyzing the model's behavior: Another approach is to analyze the model's behavior and try to understand why it is making certain predictions. This can be done by looking at the model's input data and the weights and biases of the model's parameters.
  • Debugging the training process: Another common source of errors in ML models is the training process itself. This can include issues such as overfitting, underfitting, and poor convergence. Debugging the training process often involves adjusting the model's hyperparameters or changing the training data.
  • Testing and debugging: Finally, it is important to test the model thoroughly and debug any issues that are identified. This can involve using techniques such as unit testing and integration testing to ensure that the model is working as expected.
