Interview Questions for Knowledge of Emerging Technologies

Supervised and unsupervised machine learning differ fundamentally in how they’re trained and what they accomplish. Think of it like teaching a child: supervised learning is like showing them labeled examples (‘This is a cat, this is a dog’), while unsupervised learning is like giving them a box of toys and letting them figure out the categories themselves.

Supervised learning uses labeled datasets. Each data point is tagged with the correct answer. The algorithm learns to map inputs to outputs based on these examples. Common applications include image classification (identifying objects in images), spam detection (classifying emails as spam or not spam), and medical diagnosis (predicting diseases based on patient data). For example, a supervised learning model for image recognition might be trained on thousands of images of cats and dogs, each labeled accordingly. The model learns the features that distinguish cats from dogs and can then classify new, unseen images.

Unsupervised learning, on the other hand, works with unlabeled data. The algorithm identifies patterns, structures, and relationships in the data without explicit guidance. Common applications include clustering (grouping similar data points together), anomaly detection (identifying unusual data points), and dimensionality reduction (simplifying data by reducing the number of variables). For example, a customer segmentation model might use unsupervised learning to group customers with similar purchasing behaviors into distinct segments, enabling targeted marketing campaigns.

In short: supervised learning learns from labeled examples, while unsupervised learning explores data to find inherent structures.

Blockchain is a decentralized, distributed, and immutable ledger technology. Imagine a digital record book that’s shared across many computers.
