Imagine you are designing an inverted list structure that will provide everything needed to calculate query likelihood with Dirichlet smoothing (Section 7.3.1). Which of the following are helpful to calculate a Dirichlet-smoothed query-likelihood value and can be stored efficiently in an inverted list (as before)? average document length collection frequency (how often this term occurs in collection) document length locations of term in each document

Consider the following query Q over R(A,B,C) and S(D,E,F):SELECT A,FFROM R, SWHERE C=D AND A < 1000 AND E='e'Assume there is a clustering index on E of S, an index on D of S, an index on C of R, and a clustering index on A of R. Assume the indices have equal height. Assume R and S have roughly equal sizes (in both number of blocks and number of records), and assume that σE='e'(S) is twice the size of σA<1000(R).6.a Draw the canonical query tree for the query Q.6.b Transform the canonical query tree for Q into a final query tree that is efficient to execute.6.c Describe the best query evaluation plan (with minimal cost) for Q for the information given.6.d Draw another left-deep query tree whose cost is higher than the one given in 6.c.6.e Give one example instance of relational algebra rewriting, for each rewriting rule that was used in the trees of 6.a and 6.b.
Which of the following values of distance_threshold results in 4 clusters in an AgglomerativeClustering. Consider default values for all the other parameters. Note that you should train the clustering model on the scaled feature set. 10 50 100 20
Consider the query:select *from r, swhere upper(r.A) = upper(s.A);where “upper” is a function that returns its input argument with all lowercaseletters replaced by the corresponding uppercase letters. Some database systems would use a (block) nested-loop join for this query, which can be very inefficient. Briefly explain how hash-join or merge-join can be used for this query.
So I'm having issues with MySQL and my issue is with the orders table where the columns are retrieved but the rows aren't and it's only the orders table and I include the order_line table and it works correctly.
Thus, persons are represented as pairs of integers: e = (birth, size), where the first number represents the date of birth of the person and the second his leg size. Date of birth is key. Describe how to expand the data structure of the skip list to respond effectively to the query: Max (d1, d2), which returns the date of birth of the person with the largest leg and born between dates d1 and d2.
Is it feasible that Belady's anomaly will influence the optimal page replacement approach? Justifications for your answers are requested.
I having an issue with MySQL and my issue is that I need to retrieve the rows and columns, but I can only retrieve the columns and not the rows of the ORDERS table, but when I use other tables (like the ITEM table) it works and i don't know what the problem is.
Please provide the code and explanation for the following in R for One Way ANOVA with the penguins data seta. Load the penguins data set (from the palmerpenguins library)b. Data Summaries & Assumption Check i. Create a new data frame that only has the columns species and bill_depth_mmfrom the original penguins data frame. Remove NA values from the dataframes using na.omit() ii. Create a single graph with 3 boxplots on the same scale, one for the bill depthfor each of the penguin species. Each boxplot should be a different color. Fromthis plot, are the means the same? iii. Create a new data frame for each species with the bill depth data for thatspecies. How many observations are there for each species? iv. Check the normality assumption for each subset by creating histograms and qqplots. Make sure each plot has an appropriate title. Divide your plot region into 6 sections so you can see the histogram and qqplot for each species side by side par(mfrow=c(3,2)) will give you a…
