Hello, let's say I have a column that's formatted somewhat like:
| column_name |
| A,B |
| B,C,D |
| A,D |
I want to end up with:
| column_name | foo_A | foo_B | foo_C | foo_D |
| A,B | True | True | False | False |
| B,C,D | False | True | True | True |
| A,D | True | False | False | True |
This is somewhat like "one hot" encoding, except that each sample can have multiple values, each comma-separated.
