30.4. Key Components of a Machine Learning System

Try these first

1. 1.

   What is data preprocessing?

   Hint

   Think about the steps you take before using data.

2. 2.

   Why is model evaluation important?

   Hint

   Consider the impact of using an unreliable model.

3. 3.

   What is the first step in building a machine learning model?

   • Data Collection
   • Model Evaluation
   • Deployment

   Hint

   Think about what information you need before starting any project.

4. 4.

   True or False: Model evaluation is unnecessary if the model performs well during training.

   • True
   • False

   Hint

   Consider the difference between training and practical application.

5. 5.

   Design a flowchart outlining the complete machine learning pipeline, detailing each key component and process involved from data collection to deployment.

   Hint

   Think about how each stage feeds into the next.

6. 6.

   Apply the evaluation metrics discussed in the lesson to assess a hypothetical machine learning model predicting student grades based on attendance and assignments. Identify at least three metrics you would use.

   Hint

   Reflect on the importance of each metric in determining model success.
