Background

In this assignment, you will analyse an open dataset about a marketing campaign of a Portuguese bank in order to design strategies for improving future marketing campaigns. The object of this campaign is to pursuit customers to subscribe the term deposit. The marketing campaigns were based on phone calls. The dataset contains the call information with the following attributes in Table 2.1.

More information about this dataset can be found at: https://archive.ics.uci.edu/ ml/datasets/bank+marketing.

Task Description

We provide one IPython notebook SIT742Task2.ipynb at https://github.com/tulip-lab/ sit742/tree/master/Assessment/2019, together with a csv file bank.csv at the data sub- folder. You are required to analyse this dataset using IPython notebook with Spark packages including spark.sql and pyspark.ml that you have learnt from SIT742.

IPython Notebook [60% scores]

To systematically investigate this dataset, your IPython notebook should follow the basic

6 procedures as:

(1) Import the csv file, “bank.csv”, as a Spark dataframe and name it as df, then check and explore its individual attribute.

(2) Select important attributes from df as a new dataframe df2 for further investigate. You are required to select 13 important attributes from df: `age’, `job’, `marital’,

`education’, `default’, `balance’, `housing’, `loan’, `campaign’, `pdays’,

`previous’, `poutcome’ and ‘deposit’.

(3) Remove all invalid rows in the dataframe df2 using spark.sql. Supposing that a row is invalid if at least one of its attributes contains `unknown’. For the attribute

`poutcome’, the valid values are `failure’ and `success’.

(4) Convert all categorical attributes to numerical attributes in df2 using One hot encoding, then apply Min-Max normalisation on each attribute.

(5) Perform unsupervised learning on df2 including k-means and PCA. For k-means, you can use the whole df2 as both training and testing data, and evaluate the clustering result using Accuracy. For PCA, you can generate a scatter plot using the first two components to investigate the data distribution.

?[SIT742]? 2.3. WHAT TO SUBMIT?

(6) Perform supervised learning on df2 including Logistic Regression, Decision Tree and Naive Bayes. For the three classification methods, you can use 70% of df2 as the training data and the remaining 30% as the testing data, and evaluate their prediction performance using Accuracy.

Case Study Report [40% scores]

Based on your IPython notebook results, you are required to write a case study report with 500 – 1000 words, which should include the following information:

(1) The data attribute distribution

(2) The methods/algorithms you used for data wrangling and processing

(3) The performance of both unsupervised and supervised learning on the data

(4) The important features which affect the objective (‘yes’ in ‘deposit’) [Hint: you can refer the coefficients generated from the Logistic Regression]

(5) Discuss the possible reasons for obtaining these analysis results and how to improve them

(6) Describe the group activities, such as the task distribution for group members and what you have learnt during this project.

In the Android Studio that is provided, there is a sketched Android Application that is using the default or

a custom made Keystore in order to digitally signed a text message that is provided by the user. The

user is capable of choosing the Java keystore that he wants to use as long as it is already stored in

some common Android folder. The Android Application consists of two Activities, a public one (called

PrivateUserActivity and a private one called PrivateActivity. When the application start, the Public

activity (PrivateUserActivity) is loaded. The PrivateUserActivity lets the user to write the path

where a custom keystore is going to be used. There is also a text field where the user can write the password that is needed in order to correctly open the keystore. There are also three buttons that have the

functionality shown in the following figure (1).

1. Task 1.1 (15 Marks) Implement the functionality of the Private Activity PrivateActivity so that:

• it collects and processes the information coming from PrivateUserActivity

• it extracts from the keystore the information regarding the keys and certificates and shows in

the textview the key aliases, the certificate type and the cipher that is been used.

• when the user places in the textbox shown in the Figure 1 one of the key alias and has added

a text in the other textbox (also shown in the figure 1) if the “Return Result” button is pressed,

then the provided user text is digitally signed using the keys in the chosen alias.

• the provided digital signature is returned to PrivateActivity and is printed in the appl screen

using the Toast class (see relevant code inside the provided Android project)

2. Task 1.2 (5 Marks): Based on the existing design approach and functionality that appears on the

provided Android Application as well as the code that you have developed to solve Task 1.1, explain

Assignment: Patty Plaintiff’s Really Bad Week
Due Week 7
Worth 280 points

In this assignment, you’ll need to decide whether Patty Plaintiff has any legal claims arising from a series of unfortunate events. After reading the scenario, answer the questions that follow, making sure to fully explain the basis of your decision.

Patty Plaintiff is shopping at her favorite store, Cash Mart. She is looking for a new laptop, but she can’t find one she likes. Then, realizing that she is going to be late for an appointment, she attempts to leave the store, walking very fast. However, before she can leave, she is stopped by a security guard who accuses her of shoplifting. Patty, who has taken nothing, denies any wrong doing. The officer insists and takes Patty to a small room in the back of the store. The guard tells Patty that if she attempts to leave the room she will be arrested and sent to jail. At this point, the guard leaves the room. Patty is scared and waits in the room for over an hour until the manager comes in and apologizes and tells Patty that she is free to go.

About this same time, Gerry Golfer is hitting golf balls in his backyard. Gerry decides to break out his new driver and hits a golf ball out of his backyard into the Cash Mart parking lot. The golf ball hits Patty Plaintiff on the head and knocks her unconscious just as she is leaving the store.

Five days later, after recovering from her injuries, Patty returns to work at Acme Corporation. Unfortunately, she used her company email to send her mom a personal email about her injury despite being aware that Acme’s company policy prohibits use of company email for personal communication. Patty’s supervisor, Barry Bossley, discovers Patty’s violation and Patty is reprimanded. When Patty goes home she uses her personal computer to post disparaging comments about her boss and Acme Corporation on social media. The next day Patty is fired from her job.

In a 6-10 paragraph paper, answer the following question: What types of legal claims could Patty make against Cash Mart, Gerry, and Acme Corporation? Consider the following:

    1. What are the possible tort claims that Patty can make against Cash Mart? Discuss the elements of the claim and how those elements relate to the facts in the scenario.
    2. Was Gerry negligent when he hit the golf ball that injured Patty? Discuss the elements of negligence and use facts from the scenario to support your decision.
    3. Does Patty have a right to privacy when using Acme Corporation’s e-mail system? Discuss the elements of the claim and how those elements relate to the facts in the scenario.
    4. Can Patty be legally fired from her job for making negative comments about her boss and her company on social media? Discuss the elements of the claim and how those elements relate to the facts in the scenario.
