Features en labels

Juan leidt een Data Science-team bij een bank. Zijn team wil Supervised Machine Learning gebruiken om een aanbevelingssysteem te bouwen dat het type lening voorspelt dat een klant het meest waarschijnlijk zal gebruiken. De resultaten van het aanbevelingssysteem worden gebruikt om gerichte reclame naar elke klant te sturen.

Juan heeft een gegevensset die hij wil gebruiken om zijn model te trainen. Help hem bepalen welke van deze kolommen een label is.
