Find a new regression dataset

[artidoro]

Some regression tests rely on a machine generated regression dataset (Gaussian noise on top of a linear function of a vector input). The file was introduced by #937.

We should replace this dataset with a real dataset. Justin @justinormont suggested to find something from data.gov, for example predicting the SF employee pay: https://catalog.data.gov/dataset/employee-compensation-53987

LIBSVM dataset is also commonly used in researches.

We have the following data sets that can be used as regression:

• housing
• taxi-fare

The following can be reformulated to use as a regression prediction:

• adult (predicting age from all the other variables)
• breast-cancer (predict any feature)
• iris (predict any feature)

Rogan seems to have answered this question.

[justinormont]

The work item is to replace the synthetic datasets w/ ones more representative of user datasets. Rogan has pointed out great ones we can use as replacements in our tests.

@justinormont The ones that Rogan pointed out are real datasets, breast-cancer dataset is from 1992.
