  1. You need to convert your Integer columns to Double columns before using them. You can do that with a Math Formula (Multi Column) node. Simply return the input columns.
  2. Your problem is too “ill-posed” for the logistic regression algorithm to converge within the set number of epochs (iterations). Possible solutions: increase the number of epochs, remove some of the predictors, add more observations, or use the Normalizer node to turn the numerical columns into Z-scores.

Logistic regression it’s okay.

I couldn’t solve the problem in Mlp.
Thanks.
