Medical image recognition optimal error estimation
Case context: A team is developing a machine learning model to detect anomalies in X-ray images, a task that trained radiologists perform very well. They have a training set of images but do not know the theoretical limit of performance for their model.
Question: According to the principles in Machine Learning Yearning, what steps should the team take to estimate the optimal error rate for this X-ray detection task?
Sample answer: Because this is a task humans (radiologists) are reasonably good at, the team should ask a human expert to provide labels for the images. They should then measure the accuracy of these human labels relative to their training set to estimate the optimal error rate.
Key points:
- Recognizing pictures is a task humans are good at
- Ask humans to provide labels
- Measure human accuracy relative to the training set
Rubric: The answer must propose using human experts to label the data and specify that the optimal error rate is estimated by measuring the accuracy of these human labels relative to the training set.
