On Saturday, Alina and I went on a hike up to Wildcat Peak. It took about 2 hours full circle but the sight was worth it all. I definitely plan on going on more hikes around the area because of this experience.
At the start of this week I tried to clean and analyze more recent Tstat logs from January and July of this year. To my surprise, these files were formatted differently from my previous files which meant I had to clean and compile them differently as well. This posed many unexpected problems that took much longer to solve than I first imagined. Also planned for the week was to add a way to identify the "normal" cluster to the algorithm and perform quantitative analysis on the similarities of the calculated sequences with the log(throughput). All at the same time, this content needed to be put into my poster for the intern poster session by noon on Friday. After cleaning, I tried to add the cluster identification step to the algorithm. I was running behind, so without finishing it I moved on to calculating quantitative similarity metrics. I didn't want to consider the similarity of the sequences when throughput is high (because our values turn out to be low) so I took the ...
In this week much effort was put into being able to compare average window throughput and degree of change. One challenge to overcome was how to scale the throughput data. To best understand the distribution of the average throughput's for every window, we made a histogram using the unscaled throughputs. It was evident that the magnitudes of the very high throughput dwarfed the small throughput by at least 10^2. Two methods were considered to scale the throughput; apply the reciprocal operation, (^-1), or apply a logarithmic function. The logarithmic function most evenly represents small throughput and high throughput. After choosing our scaling method we graphed the log(throughput) with the degree of change over time. From these figures, it seems there is no discernible relationship between degree of change and log(throughput). This was a big step back as Alina and I had to rethink an approach to this project.
I spent all my time this week preparing for the end of the internship. I submitted a poster for admittance to the Association for Computing Machinery poster competition to be held at the Super Computing Conference in Dallas, Texas this year. Beyond that, I spent a lot of time organizing files and finishing mandatory assignments. On Monday I submitted a minute long video to a small competition for giving elevator pitches and got an honorable mention award on Thursday, which was a tie between 5th and 6th place out of 10. Not bad for one hour of recording at midnight. Thursday was the poster session for all the interns and it went fairly well. The expense of organizing the event probably wasn't worth the amount of visitors that came to participate, though. I will say that I was one of the few interns that presented their poster to Michael Stewart Witherell, the director of the lab! Now that was cool! The research poster presented at the final poster session There was a lot plan...
