In this report paper, you will explore in detail one of the statistical learning techniques or data mining (if you have the background) approaches to research discussed in the course, applying it in the context of a specific application or methodological study. This will help you gain a deeper understanding of your chosen topic as well as gain experience in translating these ideas into practice.
Find a data set, generate your topic based on the type of dataset and what questions you want to answer from the dataset. The following task need to be performed:
Your report is base on the hands-on project.
Note: Use MS Excel or SPSS or WEKA
Answer the following questions. Please ensure to use the Author, YYYY APA citations with any content brought into the assignment.
For sparse data, discuss why considering only the presence of non-zero values might give a more accurate view of the objects than considering the actual magnitudes of values. When would such an approach not be desirable?
Describe the change in the time complexity of K-means as the number of clusters to be found increases.
Discuss the advantages and disadvantages of treating clustering as an optimization problem. Among other factors, consider efficiency, non-determinism, and whether an optimization-based approach captures all types of clusterings that are of interest.
What is the time and space complexity of fuzzy c-means? Of SOM? How do these complexities compare to those of K-means?
Explain the difference between likelihood and probability.
Give an example of a set of clusters in which merging based on the closeness of clusters leads to a more natural set of clusters than merging based on the strength of connection (interconnectedness) of clusters.
At UC, it is a priority that students are provided with strong educational programs and courses that allow them to be servant-leaders in their disciplines and communities, linking research with practice and knowledge with ethical decision-making. This assignment is a written assignment where students will demonstrate how this course research has connected and put into practice within their own career.
Assignment:
Provide a reflection of at least 500 words (or 2 pages double spaced) of how the knowledge, skills, or theories of this course have been applied, or could be applied, in a practical manner to your current work environment. If you are not currently working, share times when you have or could observe these theories and knowledge could be applied to an employment opportunity in your field of study.
Requirements:
Course Name: Enterprise Risk Management
1 Page long, APA 6th standard paper
Provide an example of an IT project from your readings, experience, and/or other sources and discuss some of the challenges faced in its implementation. Suggest ways to overcome such challenges to achieve successful outcomes.
Please only message if you can code using css
Simple assignment needed for Saturday Evening
This week’s journal article was focused on the Complexity of Information Systems Research in the Digital World. Complexity is increasing as new technologies are emerging every day. This complexity impacts human experiences. Organizations are turning to digitally enabled solutions to assist with the emergence of digitalization.
Please review the article and define the various technologies that are emerging as noted in the article. Note how these emerging technologies are impacting organizations and what organizations can to do to reduce the burden of digitalization.
Be sure to use the UC Library for scholarly research. Google Scholar is also a great source for research. Please be sure that journal articles are peer-reviewed and are published within the last five years.
The paper should meet the following requirements:
The writing should be clear and concise. Headings should be used to transition thoughts. Don’t forget that the grade also includes the quality of writing.
Consider the below schema for a library database and write relational algebra expressions for the following queries
1. Author ( authorname, citizenship, birthyear)
2. Book (isbn, title, authorname)
3. Topic (isbn, subject)
4. Branch (libname, city)
5. Instock (isbn, libname, quantity)
1. Give all authors’ names born after 1940. [0.25 Point]
2. Give the names of libraries in Sydney. [0.25 Point]
3. Give the city/cities and “isbn” where each book is held. [0.25 Point]
4. Give the title of each book on the topic of either alcohol or drugs. [0.25 Point]

Part 1 –
Following is the link of the Project
1. Iris Data Set
Run the code several times and show the intended output…you also need to EXPLAIN the output…
You will also need to provide output for the following:
Python file containing your code…
Dimensions of the data…
Sample of the data…
Statistical summary of the data…
Class distribution…
One univariate and one multivariate diagram…
Decision Tree…explain the best depth and why?…
Results of training and new data, 80%-20% split…
Accuracy report…what is it telling us?…
Confusion matrix…what is it telling us?…
Classification report…what is it telling us?…
Results of training and new data, 50%-50% split…
Accuracy report…what is it telling us?…
Confusion matrix…what is it telling us?…
Classification report…what is it telling us?…
Part 2 – Updated Code…
Now that you have a working base of code, let’s apply it to a “real world” scenario…
Find an article or video that shows a potentially SIMILAR usage of the application you created in Part 1…
Update the original application so that it “works” for the NEW application…
In this “Movie Recommendation” project, you might find an article on “book recommendations” …you would then update the original program to handle the new scenario…
YOU MUST UPDATE THE ORIGINAL CODE…do not provide entirely new code base.
Run the code several times and show the intended output…you also need to EXPLAIN the output…
You will also need to provide the same output for THIS application, as you did for the ORIGINAL application…specifically:
Python file containing your code…
Dimensions of the data…
Sample of the data…
Statistical summary of the data…
Class distribution…
One univariate and one multivariate diagram…
Decision Tree…explain the best depth and why?…
Results of training and new data, 80%-20% split…
Accuracy report…what is it telling us?…
Confusion matrix…what is it telling us?…
Classification report…what is it telling us?…
Results of training and new data, 50%-50% split…
Accuracy report…what is it telling us?…
