Generative AI vs Predictive AI :
Generative AI is all about creation. It’s designed to generate new content—like text, images, code, music, or even videos. Think of tools like ChatGPT, DALL·E, or GitHub Copilot. These models learn patterns from massive datasets and use them to produce something new that didn’t exist before.
Predictive AI, on the other hand, is focused on forecasting. It uses historical data to predict future outcomes—like predicting customer churn, stock prices, or product demand.
You’ll often see this in traditional machine learning models such as regression, classification, or time-series forecasting.
In simple terms:
Generative AI = “Create something new.”
Predictive AI = “Tell me what’s likely to happen.”

Generative AI vs Traditional Machine Learning:
Generative AI is a newer branch of AI focused on creating data—like writing text, generating art, producing music, or even designing websites. It uses advanced models like transformers, GANs (Generative Adversarial Networks), and diffusion models to understand patterns and generate new outputs. Examples include ChatGPT, Midjourney, and RunwayML.
Traditional Machine Learning, on the other hand, is more about analyzing and predicting. It involves algorithms like decision trees, linear regression, logistic regression, and k-means clustering that learn from data to make predictions or classify things. You feed it data, and it tells you something about it—like whether an email is spam, or what your next sales numbers might be.
To put it simply:
Generative AI = “Make something new from what you’ve learned.”
Traditional ML = “Understand patterns and make decisions based on them.”

Important questions to ace your machine learning interview with an approach to answer:
1. Machine Learning Project Lifecycle:
- Define the problem
- Gather and preprocess data
- Choose a model and train it
- Evaluate model performance
- Tune and optimize the model
- Deploy and maintain the model
2. Supervised vs Unsupervised Learning:
- Supervised Learning: Uses labeled data for training (e.g., predicting house prices from features).
- Unsupervised Learning: Uses unlabeled data to find patterns or groupings (e.g., clustering customer segments).
3. Evaluation Metrics for Regression:
- Mean Absolute Error (MAE)
- Mean Squared Error (MSE)
- Root Mean Squared Error (RMSE)
- R-squared (coefficient of determination)
4. Overfitting and Prevention:
- Overfitting: Model learns the noise instead of the underlying pattern.
- Prevention: Use simpler models, cross-validation, regularization.
5. Bias-Variance Tradeoff:
- Balancing error due to bias (underfitting) and variance (overfitting) to find an optimal model complexity.
6. Cross-Validation:
- Technique to assess model performance by splitting data into multiple subsets for training and validation.
7. Feature Selection Techniques:
- Filter methods (e.g., correlation analysis)
- Wrapper methods (e.g., recursive feature elimination)
- Embedded methods (e.g., Lasso regularization)
8. Assumptions of Linear Regression:
- Linearity
- Independence of errors
- Homoscedasticity (constant variance)
- No multicollinearity
9. Regularization in Linear Models:
- Adds a penalty term to the loss function to prevent overfitting by shrinking coefficients.
10. Classification vs Regression:
- Classification: Predicts a categorical outcome (e.g., class labels).
- Regression: Predicts a continuous numerical outcome (e.g., house price).
11. Dimensionality Reduction Algorithms:
- Principal Component Analysis (PCA)
- t-Distributed Stochastic Neighbor Embedding (t-SNE)
12. Decision Tree:
- Tree-like model where internal nodes represent features, branches represent decisions, and leaf nodes represent outcomes.
13. Ensemble Methods:
- Combine predictions from multiple models to improve accuracy (e.g., Random Forest, Gradient Boosting).
14. Handling Missing or Corrupted Data:
- Imputation (e.g., mean substitution)
- Removing rows or columns with missing data
- Using algorithms robust to missing values
15. Kernels in Support Vector Machines (SVM):
- Linear kernel
- Polynomial kernel
- Radial Basis Function (RBF) kernel
