Final Portfolio Project

Final Portfolio Project (submission in Week 15)

Class, the final project is due next week (week 15). Please use this week to get a start on this final project. Start working on a draft that you can continue to work on into next week for submission in Week 15 (nothing is submitted to Week 14).

Final Project Prompt:

The final portfolio project is a three- part activity. You will respond to three separate prompts but prepare your paper as one research paper. Be sure to include at least one UC library source per prompt, in addition to your textbook (which means you’ll have at least 4 sources cited).

Start your paper with an introductory paragraph.

Prompt 1 “Data Warehouse Architecture” (2-3 pages): Explain the major components of a data warehouse architecture, including the various forms of data transformations needed to prepare data for a data warehouse. Also, describe in your own words current key trends in data warehousing.

Prompt 2 “Big Data” (1-2 pages): Describe your understanding of big data and give an example of how you’ve seen big data used either personally or professionally. In your view, what demands is big data placing on organizations and data management technology?

Prompt 3 “Green Computing” (1-2 pages): One of our topics in Chapter 13 surrounds IT Green Computing. The need for green computing is becoming more obvious considering the amount of power needed to drive our computers, servers, routers, switches, and data centers. Discuss ways in which organizations can make their data centers “green”. In your discussion, find an example of an organization that has already implemented IT green computing strategies successfully. Discuss that organization and share your link. You can find examples in the UC Library.

Model

A manufacturer of wireless gaming mouse is preparing to set the price on a new model. Demand (D) is thought to depend on the price (P) and is represented by the model:

D = 2500 – 3P

The accounting department estimates that the total costs (C) can be represented by

C = 6000 + 4D

Develop a model for the total profits (Revenues minus Costs) and represent it on an Excel spreadsheet. Consider demands as units sold. Create columns for price, demand, revenue, costs, and profits.

Module 2 Readings

For the Module 2 readings, like in Module 1, we are focusing on the basic substantive concepts of Machine Learning as a subset discipline of Artificial Intelligence.

The Alpaydin MIT book is a great introduction to the topic, and over this and next Module we will be reading the book and highlighting the various components of machine learning. When reading the book, note the various components of ML: algorithms, data structures, mathematics, applications, etc. See how they are all related and are ultimately organized into a viable ML process, set of algorithms, and product in order to solve a specific problem.

Remember, in computer science our goal is to solve problems, whether they are mathematical, scientific, medical, business or related to another discipline.

Also remember Occam’s Razer when dealing with creating ML solutions. The simplist solutions are usually the best. (Especially when complexity increases software risk!!!). The brief overview is to remind you of this vital universal engineering (and life) principle.

The Brighterion white paper goes over the intersection between AI and ML. In this directed study we will read many white papers, as our goal with ML is to develop solutions to problems for industry. As a computer science and AI professional we must keep up with industry and its developments as well as the companies that are leading the AI/ML edge.

1. Read Alpaydin text: Pages 1-84

2. Read the Brighteron White paper on AI/ML

Research Project: Evaluation and User Experience

INTRODUCTION

Researchers can contribute their experience with experimentation to develop improved techniques for interface evaluation and the user experience. Guidance in conducting pilot studies, acceptance tests, surveys, interviews, and discussions would benefit large-scale development groups, but additional attention needs to be given to smaller projects and incremental-type changes. Strategies are needed to cope with evaluation for the numerous specific populations of users and the diverse forms of disabilities that users may have. In this project 2, you are the Experts in helping design and constructing psychological tests which can help in preparing validated and reliable test instruments for subjective evaluation of the varying types of interfaces, from small mobile devices to very large displays, including specialized interfaces such as gaming. Such standardized tests would allow independent groups to compare the acceptability of interfaces.

SCOPE: You are working for an Independent company and you are tasked to design an evaluation instrument tool used to profile users’ skill levels with interfaces that would be helpful in job-placement and training programs.

STEP ONE (1) Use PowerPoint (MS Suite Products or suitable Tool) to design (draw) your HCI Interface, design an Evaluation Instrument Test Tool to validate an interface for a small mobile device or a very large display to include specialized interfaces such as gaming. Please show in your design how you would incorporate quality features e.g., usability, universality, and usefulness using an AI and/or Machine Learning approach.

OBJECTIVE: This project 2 should show how do you best incorporate and evaluate qualitative data and dimensions such as fun, pleasure, joy, affect, challenge, or realism.

STEP TWO: Answer each of the following question to include why as it relates to Evaluations and the Users Experience.

  • Would benchmark datasets and task libraries help standardize evaluation?
  • How useful can researchers make automated testing against requirements documents?
  • How many users are needed to generate valid recommendations?
  • How can we better explain the differences between users’ perceptions of a task and the objective measures?
  • How do we select the best measure for a task?
  • How can life-critical applications for experienced professionals be tested reliably?
  • Is there a single usability metric that can be used and compared across types of interfaces?
  • Can we combine performance data and subjective data and create a single meaningful result?
  • Is there a scorecard that can be used to aid in the interpretation of usability results?
  • Is there a theory to explain and understand the relationship between measures?
