Please add some more options in the Data Science category

[zanardi2]

I have a Data Science gig and I cannot enter the correct metadata. There are in the "Full Project" category, from the service type, in the Overview tab.

The problems are as follow:

1. At the "Gig metadata" I have a number of options. At the "Project type", the "regression" and "categorization" options are missing. Other options do not reflect what the gig is about and this metadata is mandatory;
2. Same is with the "Task" metadata.
3. Also, at "Models and methods", I would modify "Linear Regression" to "Regression", because there are many more types of regression.

Please make the specified modifications.

Thanks!
