vector variable example

n0thing233

Hi can I get an example of vector variables?

There is nothing in the documentation here :

https://doc.dataiku.com/dss/latest/machine-learning/features-handling/vectors.html

what should be the format? what is the default delimiter?

I have comma delimited text and got this error during training:

'Invalid vector data in column 'segments': No JSON object could be decoded'

So it looks like it should be JSON format.But can I get an example?

Thanks.

Hi,

Indeed, the documentation has to be completed.

- It works only on vectors of numerical values
- The vectors should be detected as “array” in prepare steps.
- The format of an array is a string like "[ 1.111 , 2.222, 3]" (json format). To create an array from columns, you can use a formula to concatenate them.

I know this is several years old, but the documentation still has not been updated, so I'm bouncing this back to the top. It would also be a nice feature to accept JSON strings that include key value pairs, and simply ignore the keys.
