Day 16

Today at the morning meeting we reviewed more of the outlines, including mine. My outline was put on the projector and I gave a brief description of what my project was and what I am going to present. At the lab, I worked with Ron to figure out the problem I had been having the previous day with the parameter search I was doing for the MLP classifier. The problem turned out to be more complicated than anticipated. The issue was not only with my code, but also with the code for the MLP. The MLP had worked correctly when used by the pipeline, but not when used by a grid search, which I was performing and which is outside of the pipeline. Also, at one point today Ashley, Emily, and Peter dropped by the lab to see what I was working on. I did not have that much to show them, as all of my work is on my computer and I was just trying to fix an error at the time, but I did my best to describe and show them my experiment. After Ron and I fixed the problem with MLP, we and two other students in the lab went to lunch in Global Village. Some photographers there took our picture so they could use it for the website or something like that. Back at the lab, I began to run the parameter searches. At first, I had another error: the system was running out of resources. I tried switching GPUs, but it turned out to be another issue in the MLP code. Finally I was able to run the searches, and I am getting varying results. However, the results generally show that the hidden layer shape should be two layers of sixty-four neurons and that the weight decay value should be zero. Also today, while I waited for the searches to run, I began writing descriptions of the different classifiers I was testing in the Overleaf document. I also began a table for the results of my classifier experiment. Tomorrow I plan to finally run trials with the optimal parameters on the MLP classifier.
