It involves stages like collecting, cleaning, analyzing and visualizing data to support decision-making through techniques like machine learning and predictive analytics.
Ans:
- In supervised learning, where the inputs and outputs are known, the model is trained using labeled data. The system predicts results for new data by learning patterns.
- In Unsupervised Learning, the model works with unlabeled data and discovers hidden patterns, structures or groupings automatically using clustering or association techniques.
Ans:
Balance between model complexity and simplicity is represented by the bias-variance tradeoff. A model with high variance overfits by overreacting to slight changes in the training set, whereas a model with strong bias underfits by making unduly simplistic assumptions. Finding a medium ground to improve accuracy is the aim.
Ans:
Overfitting occurs when a model absorbs too much information from its training set, which may include outliers and random noise. While it performs well on the training set, it struggles to make accurate predictions on new or unseen data due to poor generalization.
Ans:
Some commonly used data visualization tools include Matplotlib and Seaborn in Python, known for their ability to create detailed charts and plots. Additionally Plotly is widely used for building dynamic, interactive graphs and dashboards that enhance data storytelling.
Ans:
Precision measures how accurately the model identifies positive results out of all predicted positives, focusing on correctness. Recall (or sensitivity) shows how well the model detects actual positive cases from the entire dataset. Together, they help evaluate the reliability of a classification model.
Ans:
A confusion matrix is table that compares expected and actual results to assess how well a categorization model performs. It includes True Positives (TP), True Negatives (TN), False Positives (FP) and False Negatives (FN), helping to measure accuracy and other performance metrics.
Ans:
Missing data can be managed in several ways. You can remove rows with null values if they’re minimal or use imputation techniques like replacing missing entries with the mean, median or mode. Advanced methods like KNN or decision tree imputation can predict missing values based on other data points.
Ans:
A machine learning technique called decision trees makes predictions using a structure resembling a flowchart. Branches show results, leaf nodes show final predictions and each node represents a judgment based on data attributes. Both classification and regression tasks make extensive use of it.
Ans:
By including a penalty term in loss function, regularization is a method for preventing overfitting in machine learning models. It limits overly complex models that fit training data too closely. Common types include L1 (Lasso) and L2 (Ridge) regularization which improve model generalization.

7. What strategies can be used to handle imbalanced datasets?
Ans:
Managing imbalanced datasets can be done through techniques like resampling, which involves oversampling the minority class or undersampling the majority class. To establish balance, techniques such SMOTE (Synthetic Minority Oversampling Technique) assist in creating synthetic data points. Moreover evaluating models using metrics like F1-score and AUC-ROC rather than accuracy offers a more reliable measure of performance.
8. How is model deployment managed in real-world AI projects?
Ans:
Model deployment involves integrating the trained AI model into production systems so it can make real-time predictions. The process includes model packaging, API creation and monitoring performance post-deployment.
