Week 10: Til Next Time

Sunday, August 7, 2022

Benjamin Johnson

This week, my work at Potomac Research was mostly completed, so I focused more on finalizing my presentation.  I practiced presenting a few times for my mentors, and once they gave me the green light, I was ready to go for Friday.  They took me out to lunch at a German restaurant in Alexandria on

Week 9: Winding Down

Sunday, July 31, 2022

Benjamin Johnson

This week at work I continued my efforts from last week to implement a hybrid reservoir computing scheme.  I added a function which passes Euler integration steps into the reservoir in addition to the previous states and input signal when the system is in feedback mode.  This serves as an additio

Week 8: Changes

Sunday, July 24, 2022

Benjamin Johnson

This week at work we switched gears on our reservoir computing (RC) project.  We decided to focus on a hybrid RC format and are trying to implement it for the Van der Pol and Lorenz equations.  The hybrid format involves adding a more direct calculation to the machine learning algorithm by provid

Week 7: Road Trips and Power Spectral Densities

Sunday, July 17, 2022

Benjamin Johnson

During this week, I continued improving our reservoir computer training algorithm for the Lorenz system.  I carried on using the output weight matrix averaging technique to model the Lorenz equations based on a set of initial conditions and parameters, then producing a Power Spectral Density (PSD

Week 6: An Explosive Holiday

Sunday, July 10, 2022

Benjamin Johnson

Once again, I had a terrific bit of fun this week.  The highlight of the week was definitely the firework show at the mall for Independence Day.  We first went down to Constitution Ave to watch the parade, then grabbed a bit of lunch at Duke’s Grocery, and finally made our way to the Washington M

Week 5: Brute Loops

Sunday, July 3, 2022

Benjamin Johnson

Throughout this week, I continued my attempt to implement a reservoir computer training protocol involving a feed-forward neural network called Keras.  This process has proven to be a substantial challenge.  Although my IDE continued working this week without problems (hallelujah), I have been un

Week 4: Beware the IDE's of June

Sunday, June 26, 2022

Benjamin Johnson

This week started off with a phenomenal bit of fun when the IDE I’ve been using to develop my code, Spyder, decided to stop working.  Gotta love Mondays.  After uninstalling and reinstalling both Spyder and Anaconda twice, I was able to get it fixed.  I then began working on an implementation of

Week 3: Neural Networks and Punk Rock

Sunday, June 19, 2022

Benjamin Johnson

This week, I continued my experiment on the various methods we can implement to train a Reservoir Computer (RC).  On Monday, I moved on from the first training technique (output matrix averaging) to the second technique: passing the mu value from the Van der Pol system directly into the RC as an
