4.4. ARTICLES 47ExercisesTask 1: Add the correct articles to the following sentences or mark theabsence of articles by −!1. true positive rate was higher in method X than methodY .2. method X had higher true positive rate than methodY .3. memory means power or process of recalling.4. X is algorithm which solves Travelling Salesman problem.algorithm X is fastest among all known T SP algorithms.5. data set X follows Normal distribution with parametersµ and σ 2 . parameter µ is mean of set X and parameterσ 2 is variance of X.6. problem X belongs to class P , if it has polynomial timealgorithm Y . time complexity of algorithm Y is O(p(n))where n is size of input and p is polynomial function.7. In next section we introduce theory of Bloom filters.8. To assess students’ proram codes, we construct bug library.bug library contains all errors which have occured in students’programs.9. infinite time Turing machines extend idea of traditionalTuring machines.10. In pattern extraction we produce set of new attributesfrom original ones. goal is to find such set of attributeswhich describes data best. goodness of representationdependes on modelling purpose, and in practice we have todefine appropriate goodness measure.11. In clustering analysis we divide data points into clusterssuch that all data points in one cluster are similar to each otherbut different from data points in other clusters.
