9. Question No 4: You are working in a classification model for a book, written by HadoopExam Learning Resources and decided to use building a text classification model for determining whether this book is for Hadoop or Cloud computing. You have to select the proper features (feature selection) hence, to cut down on the size of the feature space, you will use the mutual information of each word with the label of hadoop or cloud to select the 1000 best features to use as input to a Naive Bayes model. When you compare the performance of a model built with the 250 best features to a model built with the 1000 best features, you notice that the model with only 250 features performs slightly better on our test data. What would help you choose better features for your model? A. Include least mutual information with other selected features as a feature selection criterion B. Include the number of times each of the words appears in the book in your model C. Decrease the size of our training data D. Evaluate a model that only includes the top 100 words Answer: A https://www.exams4sure.com/databricks/databricks-certified-professional-data-scientist-practice-exam-dumps.html

10. Question No 5: Google Adwords studies the number of men, and women, clicking the advertisement on search engine during the midnight for an hour each day. Google find that the number of men that click can be modeled as a random variable with distribution Poisson(X), and likewise the number of women that click as Poisson(Y). What is likely to be the best model of the total number of advertisement clicks during the midnight for an hour ? A. Binomial(X+Y,X+Y) B. Poisson(X/Y) C. Normal(X+Y(M+Y)1/2) D. Poisson(X+Y) Answer: D https://www.exams4sure.com/databricks/databricks-certified-professional-data-scientist-practice-exam-dumps.html
