1What is the primary distinguishing characteristic of supervised learning compared to unsupervised learning?
A.Supervised learning algorithms are trained using datasets that include labeled target outputs.
B.Supervised learning algorithms do not require input feature data during model training.
C.Supervised learning algorithms only process unlabelled continuous numerical vectors.
D.Supervised learning algorithms operate exclusively through environmental reward signals.
Explanation: Supervised learning relies on training data that pairs input features with explicit ground-truth target labels. The algorithm learns a mapping function from inputs to outputs to accurately predict outcomes on unseen data. Unsupervised learning, in contrast, discovers patterns within unlabeled datasets.
2Which type of machine learning task is appropriate when the goal is to predict a continuous numerical value, such as house pricing?
A.Regression
B.Classification
C.Clustering
D.Association rule learning
Explanation: Regression is a supervised learning task focused on predicting continuous numerical target values based on input features. Examples include predicting real estate prices, temperature variations, or financial revenue. Classification predicts discrete categorical class labels.
3In a medical diagnostic system designed to determine whether a patient tumor is benign or malignant, which machine learning paradigm and task are being utilized?
A.Supervised learning for binary classification
B.Unsupervised learning for dimensionality reduction
C.Reinforcement learning for policy optimization
D.Unsupervised learning for k-means clustering
Explanation: Predicting whether a tumor is benign or malignant involves learning from historical patient records containing verified medical outcomes (labels). Because the target variable consists of two discrete categories, this is a supervised binary classification task.
4What is the primary objective of unsupervised clustering algorithms in data analysis?
A.To group unlabeled data points into clusters based on inherent feature similarities.
B.To map input features to predefined target class labels provided by human annotators.
C.To maximize cumulative numerical reward signals received from an interactive environment.
D.To compress continuous target variables into discrete binary decisions.
Explanation: Unsupervised clustering algorithms analyze unlabeled datasets to discover natural groupings or patterns. Data points within the same cluster exhibit higher similarity to one another than to points in other clusters, operating without predefined target labels.
5Which components constitute the core framework of a Reinforcement Learning (RL) problem?
A.Agent, Environment, State, Action, and Reward
B.Feature Matrix, Target Vector, Loss Function, and Gradient
C.Centroids, Distance Metric, Inertia, and Clusters
D.Inputs, Hidden Layers, Activation Functions, and Weights
Explanation: Reinforcement learning models an agent interacting with an environment over discrete time steps. At each step, the agent observes the state, selects an action, receives a scalar reward, and transitions to a new state. The goal is to learn a policy maximizing cumulative rewards.
6An e-commerce business has a vast repository of raw transaction records but only a tiny fraction labeled with fraud status. Which paradigm leverages both datasets effectively?
A.Semi-supervised learning
B.Fully supervised learning
C.Association rule mining
D.Reinforcement learning
Explanation: Semi-supervised learning combines a small amount of labeled data with a large volume of unlabeled data during training. It uses the unlabeled data to capture underlying data structure while leveraging the labeled points to guide class decision boundaries.
7A retail bank wants to identify customer spending patterns without prior category definitions. Which approach is most appropriate?
A.Unsupervised learning using customer transaction features
B.Supervised regression using historical interest rate targets
C.Supervised classification using loan default labels
D.Reinforcement learning using automated stock trading rewards
Explanation: When no prior target categories or labels exist, unsupervised learning techniques (such as k-means or hierarchical clustering) are used to explore data and segment customers based on spending similarities.
8Which statement correctly describes the function of a policy in Reinforcement Learning?
A.A policy defines the agent behavior by mapping observed states to chosen actions.
B.A policy calculates the immediate scalar numerical reward received after taking an action.
C.A policy measures the overall error distance between predicted outputs and target labels.
D.A policy stores the historical sequence of unlabelled feature matrices.
Explanation: In reinforcement learning, a policy (often written as pi) specifies the agent's strategy or decision rule, mapping observed environmental states to actions. The policy can be deterministic or stochastic.
9How does K-Nearest Neighbors (KNN) perform predictions during inference?
A.It calculates distance metrics to find the K closest training instances and votes or averages their target labels.
B.It constructs a deep sequence of decision trees to compute ensemble leaf node probabilities.
C.It computes linear hyperplanes by solving convex quadratic optimization problems.
D.It uses gradient descent to adjust internal weight matrices during test evaluation.
Explanation: KNN is a lazy, instance-based supervised learning algorithm. During inference, it identifies the K nearest training samples in feature space (using metrics like Euclidean or Manhattan distance) and predicts the majority class (classification) or average target value (regression).
10In Decision Tree algorithms, what metric is commonly used to measure node impurity when selecting feature splits for classification?
A.Gini Impurity
B.Mean Squared Error
C.Euclidean Distance
D.Cosine Similarity
Explanation: Decision tree classification algorithms (like CART) evaluate candidate feature splits using impurity metrics such as Gini Impurity or Information Gain (Entropy). Lower impurity indicates a cleaner separation of target classes.
