Machine Learning
Given some data set, construct a model that can be used to interpret or to react to new data
Different machine learning problem classes:• Supervised learning: teacher knows the correct answer• Semi-supervised learning:
– Teacher can evaluate an answer, but does not necessarily know the correct answer
– Or: teacher only knows some of the answers (or some of the data)
• Unsupervised learning: there is no teacher
The boundaries are sometimes fuzzy. We often see mixtures of methods.

Bringing Machine Learning to the Real World
• What is the research question?
• What is the nature of your data and your learning problem?
• What are the appropriate machine learning approaches?
• How can we be sure that it works?

REU Learning Goals
• Understand a range of machine learning problems and methods– Everyone will delve into more detail on some
aspects of these
• Experimental design– Experimental hypotheses– Designing an experiment to test a hypothesis– Evaluating the results of the experiment
![Page 5: Research Experiences for Undergraduates: Integrated Machine Learning Systems Sponsored by: NSF and Oklahoma EPSCoR](https://reader035.vdocuments.us/reader035/viewer/2022062806/56649ed15503460f94be02e2/html5/thumbnails/5.jpg)
REU Learning Goals II
• Statistical tools• Professional development
– Reading, critiquing, and writing papers– Giving talks– Asking questions– Attending conferences– Graduate school– Career choices– Engineering ethics (2 full days)

Student Responsibilities
• Formally join a project • Attend research meetings
– Two weekly REU meetings: one technical and one professional development
– Project-specific: determined with mentor(s)
• Reading– Books & scientific papers– Some will be assigned – others you will need
to track down yourself

Student Responsibilities• Writing
– Project reports on the wiki (incremental goals)– REU highlights to NSF– Conference or journal submission
• Presentations– Informal status reports: every few weeks
(follows wiki project report schedule)– REU Symposium talk (~30 minutes)– Talk to students at home institution

What is a scientist?
![Page 11: Research Experiences for Undergraduates: Integrated Machine Learning Systems Sponsored by: NSF and Oklahoma EPSCoR](https://reader035.vdocuments.us/reader035/viewer/2022062806/56649ed15503460f94be02e2/html5/thumbnails/11.jpg)
What to Expect
• Research is:– an exploratory process– not like taking classes
• Participate in the research of others and ask them to participate in yours
• Do some reading every day• Your research path is (in part) your own
responsibility• Focus (most of the time)

Administrivia
• Summer meetings– Tuesdays and Thursdays 1:30-3:00 CDT
• Student jobs– ???: videoconference master (+ need a
backup)– ???: OU social coordinator
