- Unsupervised Learning: The model works with unlabeled data, automatically finding patterns or clusters using techniques like clustering or association rules.
Ans:
The bias-variance tradeoff is the balance between model simplicity and complexity. High variance models overfit the training data, while high bias models underfit by being too simplistic. The goal is to find the sweet spot that minimizes error and maximizes predictive accuracy.
Ans:
Overfitting happens when a model memorizes the training data, including noise or outliers, performing well on it but failing to generalize to new data.
Ans:
Popular tools include Python libraries Matplotlib and Seaborn for static charts, and Plotly for dynamic, interactive visualizations that help communicate data insights effectively.
Ans:
Precision indicates how many predicted positives are actually correct, while Recall (sensitivity) measures how many actual positives are correctly identified. Together, they evaluate a classification model’s reliability.
Ans:
A confusion matrix is a table comparing predicted vs actual outcomes in classification problems. It shows True Positives (TP), True Negatives (TN), False Positives (FP), and False Negatives (FN), helping evaluate model performance.
Ans:
Missing data can be addressed by dropping rows with null values if minimal, imputing with mean, median, or mode, or using advanced methods like KNN or decision tree imputation to estimate missing values from existing data.
Ans:
A decision tree is a flowchart-like model used in machine learning to make predictions. Each node tests a feature, branches represent outcomes, and leaves represent final predictions. It’s commonly used for classification and regression tasks.
Ans:
Regularization adds a penalty to the loss function to prevent overfitting by discouraging overly complex models. Common types include L1 (Lasso) and L2 (Ridge) regularization, which improve model generalization on new data.
