Below dissimilarity between four data objects are given. If complete link inter-clustering distance measure is applied, and the clustering structure at the first level; immediately after the bottom of the dendrogram is {(A,B),(C),(D)}, which is a possible value for x? A В с D A В 3 3 D 4 4 О а. 2 O b. 4 О с. 3 O d. 5

Think of a search engine that employs TF*IDF weights and a vector space model. Simple systems would need to go through all documents in the collection to compute the similarity between the query and each item. Give a quick summary of how an inverted index may be used to boost the IR system's performance.

A hash table and an STL map are compared and contrasted. How is a hash table put into practise? Which alternatives to a hash table can be utilised if the number of inputs is small?

1. Write pseudocode for a brute force algorithm for motif finding. Comment on complexities.Use proper annotations and definitions.2. Prove equivalence between Motif Search and Median String Search problems. Comparethe search space in mathematical terms.     Answer all the part in detail

You'd like to study social networks. Consider the following 26 people {A,B,C,...,X,Y,Z} in a social network graph. (These people can be thought of as "nodes" or points drawn on a piece of paper.) Here, we'd like to model "followers." How many different ways can we draw arrows between two people from these 26? Here, "A-->B" (A is a follower of B) is not the same as "B-->A" (B is a follower of A). Order matters here. Enter your answer as a whole number.

The average-case performance when looking up a single search key ... a) is better with a Linked List than with a Hash Table. b) is better with a Hash Table than with an Array. c) is better with a Binary Search Tree than with a Hash Table. d) is the same with a Linked List, an Array, and a Hash Table.

Translate these specifications in to English where F(p) is "Printer p is out of service, B(p) is "Printer p is busy." L(j) is "Print job j is lost," and QG) is "Print job j is queued." (a) Ep(F(p)^ B(p))→jL(j) (b) VpB(p)→3jQ(j) (c) )^ L(j))→apF(p)

A frieze pattern is a decoration made from repeated copies of a basic unit, arranged in a row. Figure 1 shows two examples from France in about 1820. Figure 1 Example friezes a.Provide a decomposition of the problem of drawing a frieze pattern, assuming for the moment that the basic unit is repeated just 7 times. At this stage you are not trying to produce a solution, just break the problem down into smaller parts. We are looking for a decomposition that could apply to any frieze, so you should for now ignore the details of how the basic unit will be drawn. You will need to use a loop. (4 marks) In the remainder of this question, you will design and implement a program to draw the particular frieze shown in Figure 2. Figure 2 The frieze pattern for this question In this frieze the length of each horizontal and vertical segment is 25. b.Next refine your decomposition, adding more detail so that it becomes an algorithm. This is not yet a program, so you should write the…
