Hello @Thiru

There are multiple ways you can do this.

1. You can simply use correlation matrix operator and add the label to that (include special attributes). This way you can check the correlation between features and target. Automodel also has this feature. You can also use weight by correlation operator.

I recommend using automodel as it provides you with features that are prominent based on 4 factors like correlation, idness, stability and missing values. You can also find their descriptions.
