Azure Machine Learning "Hello World" using R - Concurrency, Inc. - 0 views

  • am going to show you a very simple experiement where I will create a very basic “Hello World” program using R script. Yes! This is another advantage of Azure ML studio that you can incorporate your R scripts and create a knowledge management system for your company.

  • “Humans are not good when 500 variables affect a disease. We can handle three to five to seven, maybe,” he said. “We are guided too much by opinions, not by statistical science.”

"No More Excuses": Michael M. Crow on Analytics (EDUCAUSE Review) | EDUCAUSE.edu - 0 views

  • ombining the highest levels of academic excellence, inclusiveness to a broad demographic, and maximum societal impact.
  • the number of first-time, full-time, low-income Arizona freshmen increased 647 percent from FY2003 through FY2011
  • President Crow attributes much of this success to the use of analytics.
  • ...20 more annotations...
  • If you are instead trying to educate a broader spectrum of the population, including elite students, and you aren't using analytics, you won't know what's going on.
  • use of analytics is being driven by the objective of student success
  • at ASU, you've created a culture of innovation using analytics.
  • We've had distinguished professors in the hard sciences, such as physics, say they feel ashamed that for thirty years they didn't know why certain students were learning or weren't learning. They had no idea of the reasons
  • we have infinitely more information to allow us to help students be successful. Analytics are not the end. They are the means to the end: the successful world-class university graduate who has come to us from any family, any background, any income level.
  • Crow: For us, to be a public university means engaging the demographic complexity of our society as a whole. It means understanding that demographic complexity. It means designing the institution to deal with that demographic complexity. And it means accepting highly differentiated types of intelligence: analytical intelligence, emotional intelligence. Students are not of one type but are of many, many types.
  • At ASU, I could see that we would not be able to innovate fast enough without analytics. Without analytics, we can't understand what's going on, we can't understand the complexity of what we're trying to do, and we can't measure our progress. We needed tools to help us make better decisions—about everything. How should we design academic advising? How should we design individual courses? How should we design the overall pedagogical structure of the institution? Every facet of the institution requires robust analytics.
  • Crow: Our biggest problem has been that launching an analytical tool that is not 100 percent reliable creates tension and frustration and anger in the institution.
  • We wanted an academic advisor or a student affairs dean or an associate dean to be able to have a 360-degree analytical view of a student
  • FERPA is concerned with the university releasing information outside of the institution
  • And so, with the right training and the right controls and the right discipline, we were able to build this 360 analytical tool, which has been remarkably helpful for us in terms of creating a new way to advise students.
  • partly motivated by the Virginia Tech shooting incident,
  • At ASU, we are all responsible for the care, well-being, and success of our students.
  • It can't be just the English department or just the football team that is aware of unusual behavior, with no other campus department knowing.
  • We need to be graduating 90 percent, but we can't do that without enhanced analytics,
  • when the federal government calculates graduation rates, it calculates rates only for first-time, full-time freshmen. It does not calculate whether or not students actually graduate from somewhere else. It does not count transfer students who ultimately graduate. So we have a grossly underreported performance from some institutions, creating bad data that then goes into bad policymaking. We need more flexibility and more adaptability, and we need more recognition that students are moving around.
  • There are no more excuses. If you use these analytical tools, you will know where you are, you will know what you're doing, you will know if what you are doing is working or not, and therefore you will know whether or not you need to be doing new things customized to fit your particular school or your particular demographic to be successful. We are underutilizing these tools.
  • We're trying to change from the old agricultural cycle—or whatever it is that semesters are currently based on, because nobody really knows—to cycles based on learning outcomes. That might mean a course could take two years and other courses could take three weeks. How can we allow students to individualize their learning in a structured institution?
  • Crow: We're next headed away from hard, confined definitions of learning timeframes.
  • Allow them to game and simulate their academic careers, and allow them to engage 24/7 academic advice without having to speak to an academic advisor. That's where we've found the most positive impact.

This Algorithm Can Predict Your Success At University ⚙ Co.Labs ⚙ code + comm... - 0 views

  • Administrators call it a “student success algorithm,” but it’s official name is Course Signals--and if it works, it could change the way modern universities are run.
  • six-year graduation rates are up 21.48%
  • How do students feel about having their academic careers predicted for them? How would you feel if your next student advisor was an algorithm?
  • ...4 more annotations...
  • the idea is that the more feedback students receive about their current standing, the higher the grade they will ultimately achieve.
  • getting the technology accepted by students came down to two things: understandability and access. To achieve the former, Pistilli decided to adopt the familiar metaphor of traffic-light signals to help contextualize a student’s success as they continue along a particular route.
  • a personalized message is then generated using their name, lecturer, and specific topical references (the latter to stop the message looking too automated) and sent out by email. These messages don’t simply offer students predictions about their likelihood of eventual success (or failure), but also give strategic tactical directions so that students can work to either maintain or improve their overall grades.
  • Oddly enough, students love the system. “Overwhelmingly students tell us that they want Course Signals in every single class,” Pistilli says. “They crave the the feedback.
