ANSWER ALL QUESTIONS

Assessment Task – Total Marks: 100 – Weighting: 60%

The assignment has three tasks: one individual (Task 1) and two tasks to be completed as a group.

Task 1

Using the following dataset, create a decision tree using the entropy.

Suppose  the  following dataset is  about the properties of 14  people where the  attribute  “Default” shows whether a person will default on their credit card. The attribute “Default” is the dependent attribute with two values (default = 'yes', default = 'no'). Each person has 4 features, and you want to find out how these features are going to help whether a person will default on their credit card.

a) Which one of these features is the most important feature?

b) What is the best Information Gain (IG)?

 

 

Age Income Student Credit_rate Default

0 youth high no fair no

1 youth high no excellent no

2 middle_age high no fair yes

3 senior medium no fair yes

4 senior low yes fair yes

5 senior low yes excellent no

6 middle_age low yes excellent yes

7 youth medium no fair no

8 youth low yes fair yes

9 senior medium yes fair yes

10 youth medium yes excellent yes

11 middle_age medium no excellent yes

12 middle_age high yes fair yes

13 senior medium no excellent no

Task 2

Using the hand gestures dataset available on the Moodle page, create a hand gesture recognition app in Python. Apply at least three classifiers and compare their performance. Save your Anaconda/Google Colab Notebook in this format: Your_Name_Group(A?,B?,C?)_StudentNumber_FaceRECOGNIZE.ipynb

Document your code and give full explanation about what each block of code does.

Task 3

Use Google API to get reviews for different companies. (A separate document “Google Places API Key generator.pdf” is uploaded to help you with this task.)

(It used to be in the range of 10,000 reviews that it would let you to download but even if you get anything above 1000 per company, it is

acceptable. NOTE: You can create an API or a Developer account on other platforms like Twitter, Facebook or Google Reviews …. as well)

2- Download the reviews for four companies namely ( 1- Google, Amazon,

3- Linkedin,

4- Tesla)

Using text mining technique, identify the top 10 MOST USED WORDS in each company Reviews that you have downloaded.

Represent your findings in Word Cloud Illustration for each company like the following example. The size of the words gets bigger as they become more frequently used.

 

Save your Anaconda / Colab Notebook File in Your_Name_Group(A?,B?,C?)_StudentNumber_TXTMiner.ipynb format. Document your code and give full explanation about what each block of code does.
