Froggy Jumps Association Rule Mining QuizVersion en ligne Basics of mining rules across datasets par Malaviga Masilamani 1 What is the focus of Single Dimensional Boolean Association Rules? a Rules using numeric item quantities in transactions b Rules derived from multi-table relational joins c Rules based on presence/absence of a single item in transactions 2 From which data source are Transaction Databases primarily used for mining? a Static CSV files with no timestamps b Single-row relational tables c Dynamically stored item transactions with timestamps 3 What distinguishes Multilevel Association Rules? a Rules that operate at different item hierarchies or levels b Rules that ignore hierarchies c Rules limited to a single level of items 4 What does Dimensional Association Rules extend to? a Rules that ignore facts and dimensions b Only single-dimension data c Multiple dimensions in the data warehouse (facts, dimensions) 5 Which data environment enables Multidimensional Association Rules? a Relational databases and Data Warehouses with star/snowflake schemas b NoSQL documents only c Flat files with no schema 6 What is a key characteristic of Multidimensional Association Rules? a Rules restricted to binary items b Rules that do not consider time c Rules across multiple dimensions (e.g., product, store, time) 7 Which concept is central to mining from Transaction Databases? a Clustering based on distance metrics b Neural network weights c Frequent itemsets and association rules like A -> B 8 In data warehouses, which structure often supports Multidimensional Rules? a Cube structures (OLAP cubes) with measures and dimensions b Unstructured text stores c Flat tables only 9 What does Boolean in this context imply? a Items are always in a single state b Items are either present (true) or absent (false) in a transaction c Items have continuous quantity values 10 Which stage is typical before deriving association rules? a Frequent itemset mining (e.g., Apriori, FP-Growth) b Supervised label selection c Time-series forecasting 11 What is the primary goal of decision tree induction in classification? a To encode all numeric features as branches only b To build a tree that partitions data to predict the target class c To maximize the number of leaves regardless of accuracy 12 Which method uses Bayes' theorem for classification? a K-means clustering b Bayesian classification c Support vector regression 13 In backpropagation, which elements are adjusted to reduce prediction error? a Weights of the connections b Activation functions only c Feature scaling parameters 14 Association rule mining can help derive what type of rules for classification? a Linear regression rules b Classification rules c Decision rules only for clustering 15 A common metric to evaluate classifier performance is? a Accuracy b Mean squared error c F1-score only for imbalanced data 16 What issue can distort accuracy when classes are imbalanced? a Overfitting due to too many trees b Underfitting due to excessive pruning c Class imbalance leading to biased accuracy 17 Which split criterion is often used to grow decision trees? a Random split b Entropy c Information gain 18 Which learning paradigm uses labeled examples to learn mappings? a Unsupervised learning b Supervised learning c Reinforcement learning 19 In association rule mining, which metric measures how often a rule is trusted? a Confidence b Lift c Support 20 What is a purpose of pruning in decision trees? a To increase tree depth b To maximize the number of rules c To avoid overfitting and simplify the tree
