Training Data
PronunciationTRAY-ning DAY-tuh
Definition
Training data is the set of examples used to teach a machine learning model how to recognize patterns and make predictions.
Where you hear it
During model development, data preprocessing discussions, and when evaluating AI model performance.
Examples
The model failed to recognize cats because the training data only contained images of dogs.
We need to clean the training data to remove duplicate entries and incorrect labels.
Common mistake
Assuming that more training data always fixes bad model accuracy without checking if the data is biased or low quality.
