I didn't know about SHAP graphs that's pretty cool. I'd love to be corrected but it just seems like an ensemble model of LightGBM, Gradient Boosting and Random Forest with 12 features is just overkill. Why ensemble and not just 1 of the three models ? Much less likely to overfit. Looking at the average values BTS their speechiness values are so high compared to others I'm not sure whether those other features are adding anything, seeing featureImportance would be interesting (difficult to infer the relative importance of one feature to another since all we know is the ranking but not the values).
- soylentsucks 8y agoYea the shape is pretty cool. Hm, I don't think the author used the three models in succession. I think he just tried out different models to measure the results. Yea feature importance would've been cool too. I think the SHAP value does list the order of importance on the y-axis. Wonder if there's a way to extract more signal somehow?
