Training data

How it is used

Uncountable, like 'data': 'more training data', not 'more training datas'. It is often discussed in terms of quality, coverage, licensing and privacy: what is in the training data and what is missing from it.

Example sentences

1. The model struggles with night photos because there were very few in the training data.

2. We removed all personal information from the training data before the first run.

• data augmentationCreating extra training examples by making small changes to existing ones, such as flipping or cropping images or rephrasing sentences, so that a model sees more variety.
