Data Science Online Training FAQ'S

What is Data Science, and why is it important?

Data Science is the field of study that combines statistics, programming, and domain expertise to extract meaningful insights from data.
It is important because it helps organizations:

Make data-driven decisions.
Predict future trends using machine learning models.
Optimize processes and improve business performance through data insights.

What is the difference between supervised and unsupervised learning?

Supervised Learning:
Uses labeled data (input-output pairs).
Example algorithms: Linear Regression, Decision Trees, Random Forest, SVM.
Example use case: Predicting house prices based on features.
Unsupervised Learning:
Uses unlabeled data (no predefined output).
Example algorithms: K-Means Clustering, PCA, Hierarchical Clustering.
Example use case: Customer segmentation.

What is overfitting in machine learning, and how can it be avoided?

Overfitting occurs when a model performs well on training data but poorly on unseen (test) data because it has learned noise instead of patterns.
To avoid overfitting:

Use Cross-validation.
Apply Regularization techniques (L1, L2).
Use Dropout in neural networks.
Simplify the model or gather more data.

What is the difference between classification and regression?

Classification: Predicts categorical outcomes (discrete values).
Example: Spam or Not Spam, Disease or No Disease.
Algorithms: Logistic Regression, Decision Trees, Random Forest.
Regression: Predicts continuous outcomes (numeric values).
Example: Predicting sales amount or temperature.
Algorithms: Linear Regression, Lasso, Ridge Regression.

What is the role of feature selection in data science?

Feature selection is the process of choosing the most relevant variables (features) for building a model.
It improves model accuracy and reduces complexity.
Common methods:

Filter methods: Correlation, Chi-square test.
Wrapper methods: Recursive Feature Elimination (RFE).
Embedded methods: Lasso Regression, Decision Tree importance.
