Coefficient of Logistic Regression Using TPOT #1269

Closed manbau10 closed 1 year ago

manbau10 commented 1 year ago

I built a model using Logistic regression in TPOT classifier. I used model.fitted_pipeline_.steps[-1][1].coef_ to get the coefficients. However, the output returns 23 coefficient values, whereas the features are only 10.

Can someone help on this, please?

What does the rest of the pipeline look like? Sometimes transformers, feature unions, or stackingestimators increase the number of features.
