Submissions are scored using MCRMSE, mean columnwise root mean squared error:

MCRMSE=1𝑁𝑡∑𝑗=1𝑁𝑡1𝑛∑𝑖=1𝑛(𝑦𝑖𝑗−𝑦̂ 𝑖𝑗)2‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾⎷
where 𝑁𝑡
 is the number of scored ground truth target columns, and 𝑦
 and 𝑦̂ 
 are the actual and predicted values, respectively.

Submission File
For each text_id in the test set, you must predict a value for each of the six analytic measures (described on the Data page). The file should contain a header and have the following format:

text_id,cohesion,syntax,vocabulary,phraseology,grammar,conventions
