Week 9 (July 31 - August 4)

Overview

This week I worked on my final report for DREU, performed my last pilot study for my project, and performed analysis on data from said pilot study with machine learning algorithms.

Monday

This day I worked on my final report for DREU.

Afterward, I attended the lab-wide "what are we going to do this week" meeting. I received the assignments of working on the data analysis for my study and to perform a pilot study on tuesday.

Afterward, I attended the weekly ITS meeting, where we discuss everything going on in the overarching ITS area. There I and the lab director worked out answers to those questions I had worked out with the grad student the previous week.

Tuesday

This day I ran what was the last pilot study for my project. All the flags were logged, the fNIRS data connection did not crash, everything went well.

Afterward, I attempted to run machine learning analysis on the data I collected from the pilot study. I could not get the program to successfully parse the files I was sending it, and scheduled to meet with a grad student in the lab to work out what was not working; in the meantime, they sent me some example files for me to assess what was wrong with mine.

Wednesday

This day I succeeded in running machine learning analysis on the data from the day previous's pilot study. I met with the grad student as above mentioned to discuss in what ways I should present the data to the machine learning analysis program and, afterward, spent some time getting said data into the decided-on configuration

The data comes in six channels, each of which has ~200 values per event and collectively has 31 events per channel. The decided-on data set consists of the minimum, maximum, average, median, and standard deviation for each event for each channel. Using the Attribute-Selected Classifier algorithm on this data set, its accuracy comes out at ~74%, which is higher than any other algorithm-data set pair tested.

Thursday

This day I hit a wall with my final report and sent it to my grad student mentor to look at. I also reviewed the data analysis from the day before.

Friday

This day I attended the lab-wide weekly "what did you do this week?" meeting. I presented on having worked on my final report for DREU, on performing my last Pilot Study, and on the machine learning analysis I ran on the data from said pilot study.
