QUESTION 1 1. The two examples of measures to evaluate the performance of a classifier in a matrix are Sentiments and Recall measures Precision and Emoticons measures Precision and Recall measures Sentiments and Emoticons measures 2 points QUESTION 2 1. The four deliverables to satisfy the needs of various stakeholders are: A presentation for a project vendor, A presentation for an analytical audience, Technical specification documents, and Well-annotated production code A presentation for a project sponsor, A presentation for an analytical data, Technical specification documents, and Well-annotated production code A presentation for a project sponsor, A presentation for an analytical audience, Technical specification values, and Well-annotated production code A presentation for a project sponsor, A presentation for an analytical audience, Technical specification documents, and Well-annotated production code 2 points QUESTION 3 1. Emoticons helps to easily detect sentiments of ____________________ Simple tweets in lesser structure Mulitiple tweets in basic lesser structure Simple tweets in millions or less Multiple tweets in millions or more 2 points QUESTION 4 1. What is the function of external libraries such as MADlib? can be used by nonSQL to read and write within a database can be used by nonSQL to identify redundant values within a database can be used by SQL to conduct non-statistical analyses within a database can be used by SQL to conduct statistical analyses within a database 2 points QUESTION 5 1. One of the merit of an ARIMA modeling is that? the analysis are based on static data for the variable of interest. the analysis are based on non-static data for the variable of interest. the analysis are based on non-historical time series data for the variable of interest. the analysis are based on historical time series data for the variable of interest. 2 points QUESTION 6 1. HBase as a NoSQL (Not only Structured Query Language) maintains recent changes in the memory to ensure? the availability of the alphanumerical latest data the availability of the non-alphanumerical latest data the real-time availability of the latest data the real-time availability of the previous data 2 points QUESTION 7 1. Why is Time series analysis different from other statistical techniques? because some non-statistical analyses assume the observations are independent of each other. because most statistical analyses assume the observations are independent of each other. because some data models assume the observations are dependent of each other. because some data models assume the observations are independent of all atrributes. 2 points QUESTION 8 1. What is the best option for real-time processing that includes read and writes? Apache HBase MapReduce Logic Pig and Hive Hadoop Distributed File System 2 points QUESTION 9 1. The complexity of SQL queries uses ________________ to compute values such as _________________ with original dataset. Window functions and media values Window functions and rolling averages Table functions and media values Table functions and dynamic values 2 points QUESTION 10 1. Kalman filtering is useful with the following except? analyze real-time inputs about a system that can exist in certain states. uses an underlying model of how the various components of the system interact addresses time series with nonconstant variance or volatility. processes the various inputs, identify the errors, and predicts the current state. …
