They share the plan with you. Can you quickly describe to your team members what is the potential problem in their plan in three sentences? 1. Split data into training & test data 2. Standardize training data 3. Train model Mon training data 4. Standardize test data 5. Use model M/ to predict test data 6. Evaluate classification quality
