Meaning
A specialist who uses advanced statistical methods, machine learning algorithms, and predictive modeling to solve complex data challenges.
Three examples from work
Machine learning model
POCan we predict which users are at risk of churning?
Data ScientistWe trained a random forest classifier that flags churn risk with 85% accuracy.
Recommendation engine
LeadHow does our product recommendation model handle cold start users?
Data ScientistWe fall back to popularity-weighted category rankings until they interact with three items.
Data hygiene
Data ScientistWe need to clean outliers and normalize input features before model training.
DevI'll build an automated preprocessing pipeline in Python.
While Data Analysts focus on historical reporting and visualization, Data Scientists build predictive models and machine learning pipelines.
