**Customer question: how do we know which words/n-grams increase confidence in the predictions?**

<span style="color:red;font-size: 1rem"> `Robot 2`</span>

The [Word Cloud](word-cloud) is useful for this!


<span style="color:red;font-size: 1rem"> `Robot 3`</span>

You can also look at the [coefficients](coefficients) directly for any linear model with n-grams.

Finally we’ve got [Prediction Explanations](predex-text) for text features.

Thanks for the response.  I love these and they make sense. I recommended word cloud but she indicated that that was intensity not confidence (to me they are highly related).

Our linear models are regularized so low confidence words will be dropped.
