Essay Topic: Recommender Systems (Datamining subject)

Overview: The purpose of this assignment is to explore the processes associated with Recommender Systems.

Automated recommendations have become a pervasive feature of our online user experience, and due to their practical importance, recommender systems also represent an active area of scientific research. Along with the availability of new knowledge sources, including both structured and unstructured data that contain user-generated content, comes a steady stream of new systems that leverage such information to make better predictions. Recently, recommender systems have also emerged in the biomedical sciences and the objectives are the same in these applications, to predict ratings for missing items.

  • Recommender systems. What is a recommender system? Describe the purpose and explain how this application works to help businesses serve their target market more effectively. Also, please explain the ways in which a recommender system differs from a customer or product-based system..
  • Contrast with traditional systems. . Please explain how a recommender system differs from a typical classification or predictive modeling system. For example, logistic regression is perhaps the most widely used statistical model for classification. It is more preferable to CF because of the ensemble feature, ability to handle missing data, and it is generally robust to noise and outliers.
  • Collaborative filtering (CF). Please outline one method of collaborative filtering. Please discuss why it works in the context of recommender systems and describe what its limitations are in practice. What modern techniques/systems are available to overcome these limitations? For example, memory-based algorithms can group every user with similar interests and identify the neighbors of a new user or currently active user to anticipate the preferences of new items that would be of interest.

5 1 discussion shared memory pages

by

Shared memory pages are an example of a topic where a picture is worth a thousand words. Find at least one illustration in Google Images by entering the search key “shared memory pages” in the search box. Be sure to enter it in the search box with quotes so the entire phrase is interpreted by the search engine as a single string.

Using an illustration you find, make that picture the focus of your post. Create a Discussion Topic post that outlines the function of shared memory pages. Go into detail about the proper operation of shared memory pages as described by the course textbook. If you find an illustration that does not agree with the course textbook, be sure to use it and make any inconsistencies the focus of your post.

It is very important that you properly attribute the image by listing the original author(s) of the illustration you find. Go to Citing Your Sources Guide to find instructions and examples of using proper attribution.

After your initial post, respond constructively to two of your peers’ posts after comparing your initial post to their initial posts. Justify your suggestions for the addition or revision of any of the benefits and drawbacks of using shared pages.

Comment on the accuracy of their specification of the conditions under which the practice provides performance benefits, as well as the specific instances when efficiency is negatively impacted.

Position Analysis Paper: The Growth of Adult Corrections in the United States

Background: The growth of adult corrections in the United States is a critical issue for the correctional administrator as evidenced by a number of the readings in the first few weeks of this class. It is a perennial political policy issue for legislators, a difficult challenge for the executive branch of government, and a popular topic for the wide variety of news media available to the public today. Growth affects departmental policy, program opportunities and, most importantly, budget development. Although there are dramatic variations from state to state, there are clear trends that can be analyzed projecting future correctional growth. Even if no growth occurs in caseload, increases in the cost of inflation guarantees that the future budget will be larger than the current year appropriation.

Assignment: The objective of this assignment is to evaluate the history of U.S. prison correctional populations since 1980 and develop some conclusions regarding the probable impact of the trend you identify upon the U.S. correctional system. Students are to use library resources to find at least three peer reviewed, refereed or academic journal articles (or other reference documents once this minimum requirement is achieved) relating to the growth of adult corrections in the United States during this critical time period. One of the purposes of this assignment is to develop the student’s ability to do graduate level research on a topic. The paper must be a minimum of five complete pages of text. Please insure that you address the following issues in your essay:

  • Document the overall growth of adult correctional (prison) populations in the United States (keeping in mind that measurement is the key to this element).
  • Identify the measurement definitions and important measurement issues related to this trend. (For example, if the general population increases during that period by a specific percentage and the prison population grows by the same percentage, there is really no “real” growth associated with that trend. It should be a population growth that is anticipated and funded). Insure that you identify and discuss the term “incarceration rate” in your analysis and that it specifically a rate measuring the prison population. Do not include jails, parole and probation in this rate.
  • The identification of key factors associated with this growth pattern (what are the documented issues you can identify and cite that have fueled these changes).
  • The documented impact associated with this growth on correctional systems (notice this does not include generic sociological impacts).
  • The possible solutions to correctional population growth or the continuing efforts associated with the relief of growth tendencies.
  • The probable results of the correctional growth trend you have identified.

SLP Assignment

In a 2-page submission, not counting the cover and references pages, respond to the following questions on the Cultural Identify Worksheet regarding your knowledge of your own and your employer’s corporate culture and cultural diversity.

Cultural Identifier Worksheet

  1. Name three cultural identifiers that you identify with most. Describe in detail how you identify with these three.
  2. Which of these cultural identifiers do you see in the people with whom you work or play?
  3. Do you consider your place of work as diverse? In what ways?
  4. From the short list you made in #1, select the one that you identify with the most.
  5. What is it that you like the most about this cultural identifier?
  6. From the list above, select the one identifier that you identify with the least. Explain why it does not fit you.
  7. Do you see the cultural identifier in #6 in those with whom you work or play?
  8. List some stereotypes about your culture that do not apply to you.
  9. The following is a short list of some of the ways people respond to others’ cultural and diversity identifiers either through their thoughts, words, or deeds.
  • Prejudice–an attitude about another person or group of people based on stereotypes
  • Discrimination–an action or behavior based on prejudice
  • Racism–prejudice or discrimination based on race/ethnicity
  • Sexism–prejudice or discrimination based on gender

In discussions of these terms, an issue that sometimes arises is that prejudice and discrimination can be positive. It is important to note that when these issues are discussed in the context of cultural diversity, they are generally considered negative and very easy to identify. In what instance would prejudice or discrimination be a positive? Why is it so hard to identify the positive ones?

Note: A URL (website address) is NOT a reference. A reference always contains four parts: author, publication date, article title, and the source of the article. Sometimes there is no author, but the APA manual tells you what you can put in that spot instead, such as the first few words of the article title. The source for a high-quality peer-reviewed journal article is the journal.

In this week, you examined the security principle of collection and correlation. The gathering of system related information about national infrastructure is key for security analysis. In the same vein, correlation involves a specific type of analysis that can be performed to identify if security-related indicators emerge from the analysis. Discuss the importance of the security principle of collection and correlation. Identify some important sources from which information needs to be collected in the context of national and critical infrastructure protection. Also, identify the four distinct analytic methods that are available for the correlation of cyber security information. Provide examples and identify challenges that are involved in collection and correlation.

Please write an essay (of about 500 words) or provide short answers that address some (or all) of the following questions:

Compared to the start of the semester, do you think you have made any progress in your acting?
How have your thoughts about what it means “TO ACT” changed?
Can you define or describe what GOOD ACTING is? What are the elements that make up a strong performance?
What aspects of the techniques we have worked on so far do you feel you want to work on in your final scene?
What areas do you feel you need to improve on?
What is your strategy for maintaining a good work ethic in the final scene, when you are going to be working with a scene partner?
What has been your favorite aspect of the class so far? What aspect of your own performance are you most proud of?
What assignment did you feel you did best on?
Have you disappointed yourself in any of the assignments? How are you going to ensure that doesn’t happen with the final scene?
Is the professor helping you learn to think critically about acting?
Any other comments about the class are welcome.

In your answer(s), please remember that THE FOUNDATION OF ACTING IS THE REALITY OF DOING, as Sanford Meisner would say. It is not your job as an actor to produce emotions in yourself, it is to produce emotions in others: your scene partner(s) and by extension, the audience. In your essay, please use some of the vocabulary terms we’ve discussed in class, including Objective, Tactic, Action, Obstacles, Substitution, Given Circumstances, Subtext, etc.

This essay is worth up to 5 points in your final grade, so please answer it truthfully and thoughtfully. You may think through your performances in each assignment so far to help gauge your progress and areas that need improvement.

ABOUT ESSAY TOPICS

Choose from one of the four essay topics that are PROVIDED HERE.Click to download this TOPIC LIST)

TOPIC … TO THESIS … TO ESSAY… These topics are broad and should be used only as starting points. Read through all four of them carefully. Choose one as the basis for your essay, and then sharpen your focus. In response to issues raised by the topic, formulate your thesis position – one that will allow you to make your literary analysis / argument. Your thesis should be specific, committed to a point of view about something, and allow you to integrate some insights from the play and other sources, in order to shape and drive and shape a full-length essay.

REQUIRED SOURCES & SOURCE TYPES:

As support (or counter evidence) for your thesis, your primary source will be the text of Othello, but you should also integrate relevant insights and/or quoted material from 2 or more additional sources so that you have a minimum of 3 sources total. See below:

  • Your first required source is the text of the play, Othello

  • At least one other source must be from the course’s Othello Critical Database.

  • Your other, additional sources may be any of the following:

    • Additional readings from the Othello Critical Database

    • Other assigned external readings (not Canvas lectures) in drama unit modules

    • Assigned video clips – find links to all of them here

    • Theoretical readings from the Donald Hall text, Cultural and Literary Theory

All sources must be credited accurately and cited correctly in MLA format.

  • Again: The play itself must be cited correctly and included as a source in your Works Cited. Do not cite from the SparkNotes (“No Fear Shakespeare”), and do not cite from alternative publications in which the play appears.

About the Critical Database of Othello Readings:

These are all scholarly, analytical essays that consider the play from various angles, focused on specific aspects or concerns. They should be very useful to you as sources of insight, but also as models of critical writing and academic tone. Choose a minimum of one to use with your essay. This will be your second source, after the play itself. Your third (and optional fourth) source may also be database readings, but this is not required.

You will complete at least one database reading (of your choosing) as part of a separate assignment in Module 6, and if it’s relevant, you may use the same one as one of your sources in your formal essay (or choose not to).

TIP: As you skim the database, don’t choose readings based solely on title – many of these essays end up going into surprising directions, or examine a range of topics – race, gender, language, irony, symbolism, and so on. Skim as many as you can as you progress from general prompt to thesis idea to the formulation of your argument.

THESIS, THESIS, THESIS:

RESOURCES for developing a point of view can be found by reviewing the material on different critical literary models you’ve read so far, and by consulting the relevant links in the Othello Essay Planning Guide.

Begin drafting your paper only after you have revised your thesis multiple times.

The literary research essay is a critical analysis resulting from a close examination of of Shakespeare’s Othello. The subject, focus, approach, and shape of the essay will be determined by your thesis – a specific, substantive, and arguable claim that should be clearly articulated and established in the introduction to your paper. The thesis must be sufficiently narrow and suitably challenging.

Spend time revising it and reviewing the thesis-related readings, then revising it again. The success of your paper will depend largely on the strength of your thesis. Write multiple drafts of the thesis. statement, until you arrive at one that is no longer general, no longer a statement of the obvious, wordy, compromised by vague language, unfocused, or that sounds like plot description masquerading as argument and analysis.

Challenge yourself to revise until your topic, position and rationale (three necessary elements in any thesis) are suitably complex and well articulated.

Voice, voice, voice: Sound like yourself! Maintain a formal, academic approach but don’t write stuffy, dry, sentences. Be imaginative and descriptive. Take the time to explain your ideas and your reasoning.

Pitfalls to Avoid:

Remember the importance of a focused claim; within the constraints of an essay, you cannot write about everything. Do not attempt to tackle every subject, insight, or observation that occurs to you.

Nor should you spend your time retelling the play, or explaining the most obvious conclusions one might draw from it, even after the most casual reading.

Commit to thoroughly exploring your claim. Learning how to zero in on a sharply defined area of interest is a key skill you’ll need to complete this assignment; develop a narrow, specific claim that you examine and defend in depth, rather than a vague or overly general claim that you end up exploring only superficially.

ESSAY STRUCTURE:

INTRO, BODY, & CONCLUSION

This is not a giant five-paragraph essay, so do not approach it that way.

While that rigid model may have served you in earlier classes or in high school, it is too constraining and formulaic to be useful in this context. Your thesis should articulate a college-level, arguable claim (not name three ‘things” as a way to set up a paragraph sequence), your paper will require more paragraph breaks than only five, and you will need to develop a more thoughtful organizing principle and chain of transitions from paragraph to paragraph than the basic formula of:

AVOID THIS TIRED FORMULA: Introduction (three items are listed) + 3 paragraphs + conclusion = 5 paragraphs = paper

It is not suitable for this assignment, or this course level. Your essay should, however, still contain the basic essay components: introduction, body and conclusion, just not arranged according to this rigid formula.

Body:

You must include in the course of your argument, your examination and evaluation of a valid counterargument to your thesis claim. Valid counterarguments are not contrived, wholly invented or lacking in credibility – they are viable challenges to your own argument that, presented and responded to properly, will strengthen your own position. Where to place your counterargument(s)? There is no one answer to this question. You might decide to address challenges to your thesis throughout the body of your essay or devote one section to the counterclaims. It’s strongly recommended you visit the writing links in your Student Support Guide which address this matter specifically.

Your topic sentences are critical for shaping your essay and advancing your focused argument. Your paragraphs should cohere and be sequenced logically. For guidance in developing the body of your essay, use the writing links in the Student Support Guide and in the Othello Essay Planning Guide.

COUNTERARGUMENT:

In the course of your paper, aim to explore potential counter-evidence to your claim, or an alternative (valid) interpretation to your point of view about some or all your evidence. Incorporate a reasoned, relevant counterargument, however narrow or limited.

Your counterargument:

  • Should not seem contrived or strain credulity – don’t invent some kind of “some people say…” counterargument.
  • It does not have to be a direct disagreement with your conclusions or interpretation, but could represent an alternative interpretation or a position that differs from yours in emphasis.
  • The counter-argument (or challenge) should be valid – a challenge that complicates some or all aspects of your thesis, in order to invite your response, thereby giving your own argument more depth and nuance.
  • As a challenge to your point of view, the counter-argument doesn’t necessarily have to absolutely reject your claim – it could a subtler challenge than that.
