Consider a collection C with 100,000 documents. “Riverside” and “California” have 500 and 1000 occurrences in C. Each document in C has on average 1000 words. One of these documents is D1: University of California, Riverside, or UC Riverside Consider query Q: Riverside California 1. What is the score of D1 for Q if we use unigram Language Model-based ranking and Jeliker-Mercer Smoothing with lambda=0.5?
The similarity of two documents (each with distinct words) is defined to be thesize of the intersection divided by the size of the union. For example, if the documents consist ofintegers, the similarity of {1, 5, 3} and { 1, 7, 2, 3} is 0. 4, because the intersection has size2 and the union has size 5.We have a long list of documents (with distinct values and each with an associated ID) where thesimilarity is believed to be "sparse:'That is, any two arbitrarily selected documents are very likely tohave similarity O. Design an algorithm that returns a list of pairs of document IDs and the associatedsimilarity.Print only the pairs with similarity greater than 0. Empty documents should not be printed at all. Forsimplicity, you may assume each document is represented as an array of distinct integers.EXAMPLEInput:13: {14, 15, 100, 9, 3}16: {32, 1, 9, 3, 5}19: {15, 29, 2, 6, 8, 7}24: {7, 10}Output:ID1, ID213, 1913, 1619, 240.10.250.14285714285714285

Given an unlabeled dataset {x(1), ... , x(m)}. The K-mean algorithm has been run with 40 different random initializations, and 40 different clusterings of the data have been obtained. Describe how we should use Ex(1) – µ01² to choose the best m clustering.

Computer Science Suppose that the family is a (d1, d2, p1, p2)-sensitive LSH family. What does this mean specifically with respect to the distance parameters d1 < d2 and the probability parameters p1 > p2? What is the false positive rate and the false positive rate of the family?
Assume we have a limited number of data points for training and validation and we are using k-fold cross-validation to calculate the average error for finding the hyperparameters. For a fixed set of hyperparameters, increasing the value of k will increase the average error on k-folds. True False
From 2d array [[-1,4,-1,-1],[-1,-1,7,10],[-1,-1,-1,1],[-1,-1,-1,-1]], where each entry in the i-th row and the j-th column of the matrix corresponds to the duration of the activity between the 2 points, with -1 implying that there is no activity. Write a functions in python that computes the earliest event time, latest event time and the total flow and the use these to caclutate the critical path The graph below shows where the 2d array has come from for my background information.
