Topics Covered:

  1. Data Collection and Preprocessing:

    • Identify relevant data sources.

    • Collect, clean, and preprocess the data.

  2. Exploratory Data Analysis (EDA):

    • Understand the data’s structure and relationships.

    • Identify patterns, trends, and potential outliers.

  3. Feature Engineering:

    • Create new features from existing data.

    • Select and transform features for model input.

  4. Model Building:

    • Choose appropriate algorithms for the problem.

    • Train and validate models using the data.

  5. Model Evaluation:

    • Assess model performance using metrics.

    • Tune hyperparameters for optimization.

  6. Model Deployment:

    • Integrate the model into the production environment.

  7. Monitoring and Maintenance:

    • Continuously monitor model performance.

    • Update and retrain the model as needed.

  8. Interpretation and Communication:

    • Explain model predictions to stakeholders.

    • Communicate insights and findings.

Sample Questions:

1- When selecting an algorithm for a problem, what is the first step you should take?

1) Choose the most complex algorithm

2) Use the algorithm you are most comfortable with

3) Understand the problem’s nature

4) Pick the algorithm with the highest accuracy

Explanation:

The correct Answer is :Understand the problem’s nature

The first step is to understand the nature of the problem, whether it’s classification, regression, etc.

2- When splitting data into training and validation sets, what is the general rule of thumb for the proportion of data allocated for training?

1) 20% for training, 80% for validation

2) 50% for training, 50% for validation

3) 70% for training, 30% for validation

4) 80% for training, 20% for validation

Explanation:

The correct Answer is :70% for training, 30% for validation

A common rule of thumb is to allocate around 70-80% of the data for training and the remaining for validation.

3- In the context of deploying machine learning models, what is the primary purpose of feature scaling and normalization?

1) To prevent overfitting

2) To speed up prediction times

3) To reduce model complexity

4) To ensure consistent data range for predictions

Explanation:

The correct Answer is : 4)To ensure consistent data range for predictions

Feature scaling and normalization ensure that input data falls within a consistent range, preventing issues when making predictions
