A 9 month old presents to clinic with 2 days history of acute, intermittent cough without fever, stridor, retractions, or cyanosis. Cough start 2 evenings ago after dinner. On exam, well-appearing with intermittent dry cough, no retractions, prominent xyphoid process.  Wheezing heard at the RML that does not resolve with coughing. Your differential diagnosis includes foreign body, asthma, bacterial pneumonia.  You are most suspicious for foreign body because which anatomical risk factor?

What distinguishes hierarchical agglomerative clustering from k-means clustering?

In hierarchical clustering, the dendrogram can be used to determine the optimal number of clusters by cutting it at different levels.

Using the points from clusters C1 and C2 found in Question 19, What will be the coordinates of the the 2 centroids (C1 and C2 centroids) after being recalculated after the first iteration?   Please show your work. C1 centroid =  C2 centroid = 

The Apriori algorithm stops generating itemsets when no more frequent itemsets can be found that meet the minimum support threshold.

Assume you run a clustering algorithm on a dataset that produces a clusters with 4 observations. In the table below, you find the 4 observations and the corresponding attributes. Compute the centroid for this cluster. You can round numbers to 2 decimals.    Observations Feature 1 Feature 2 Feature 3 A 23 15 34 B 14 9 32 C 41 10 36 D 42 10 22

Next, assume you and your colleagues run the algorithm again and find the association rules shown in the table below. Your colleagues suggest to use the association rule  {License to Wed}                 => {Terminator 3: Rise of the Machines} to make recommendations, which is the rule with the highest lift.  As a reminder, your company asked you to provide some insights into which movie(s) should be recommended to individuals who have already watched the movie  “Terminator 3: Rise of the Machines”.  Do you agree with your colleagues? Clearly explain why or why not. If you do not agree, select another association rule that you believe would be better candidate. You have to clearly motivate your choice.   lhs rhs support confidence lift count {License to Wed} {Terminator 3: Rise of the Machines} 0.1527 0.6456 1.7113 102 {Men in Black II} {Terminator 3: Rise of the Machines} 0.1692 0.6141 1.6279 113 {Once Were Warriors} {Terminator 3: Rise of the Machines} 0.1751 0.5680 1.5055 117 {Terminator 3: Rise of the Machines} {Once Were Warriors} 0.1751 0.4643 1.5055 117 {The 39 Steps} {Terminator 3: Rise of the Machines} 0.1766 0.5086 1.3482 118 {Terminator 3: Rise of the Machines} {The 39 Steps} 0.1766 0.4683 1.3482 118

Answer the following questions using complete sentences. You may write in paragraph form (writing all answers in one free-flowing paragraph) or in list form (using numbers or bullets to separate the responses). Answer EVERY question. Write 100+ words overall. (You can see the word count at the bottom right.)    It’s almost time to start writing! Take a moment to reflect: Do you feel prepared to start writing your SRW? Why or why not? The draft is due tomorrow night. When do you plan to work on it (besides here in class)? What struggles do you think you might face as you start writing? What will you do to overcome those struggles?

A large volume of distribution generally indicates that the drug remains in the blood (ie: does not distribute extensively into organs/tissues).
