Data availability

As explained in Deep Learning with R, Third Edition

Data availability is the extent to which suitable examples and target annotations exist for developing a predictive model.

Data availability is the extent to which suitable examples and target annotations exist for developing a predictive model. It often limits whether a machine-learning problem is feasible: a system can learn sentiment classification only when both movie reviews and sentiment annotations are available. section 6.1.1

Movie-review sentiment classification

Before choosing a model, check whether the project has review texts paired with sentiment labels. If those annotations do not exist, collecting and annotating a dataset becomes necessary. section 6.1.1

How Deep Learning with R, Third Edition covers it

How deep it goes
Defines the constraint and illustrates it with sentiment data, stopping at problem framing rather than detailing dataset collection or annotation procedures.
Examples
Uses movie reviews paired with sentiment annotations as the central example.
What you can do after
Evaluate whether a prediction task is learnable from existing data and recognize when collecting and annotating new examples is necessary.
How it connects
Connects training data and annotations with machine-learning tasks such as classification, regression, ranking, and clustering.
