Day 15

Today I made a lot of slow and steady progress. With the paper and the CAE experiment out of the way (for now), I focused on the ladder network code. First, I adapted the code to be object-oriented, so that it would (mostly) work within our pipeline. Every few iterations, I tested the code with Pavia U and MNIST, just to make sure I didn't stray away from the 80% and 98% I achieved earlier. I would guess that failing to do so is what gives rise to hard-to-trace bugs, and nobody likes those. There was one issue where the model would crash and burn around epoch 50, and predict nothing at all. This might be linked to the NaN loss that was occurring in the previous ladder network code, and I think I've found the solution. Whether I have succeeded or failed will be in tomorrow's blog post. I haven't had enough time to run >50 epochs with the fix yet, and everybody likes a good cliffhanger. Tune in next week to find out who shot Nate and the real reason he left to run in the mountains.

Day 2

Day 2 started with a very brief meeting where we went over the schedule for the next six weeks. Abstract, outline, presentation; two weeks per task. It was at this point that I realized the difficulty of making technical topics sound interesting, then I immediately dismissed the problem as one for my future self. Today was dedicated to Support Vector Machine (SVM) creation, evaluation, and optimization. I was unaware of many of the wonderful functions included in the provided libraries, and ended up doing the data reformatting less elegantly. It still worked, so I left it. When I finished up my SVM code, I tried to help Nate with the errors he was running into. The keyword here is "tried." Note that it's not easy to explain concepts that you figured out hours earlier and happen to be more complicated than they should be. Nate was a good sport about it though, and with Ron's help, he had a good idea of the solution by the end of the day. For the last part of the day,

Day 28

Week 6 of the internship; the final presentation is on Thursday. It doesn't feel like week 6, but that's probably because I missed almost all of week 4. Regardless, there was much work to do before Thursday, so Nate and I rehearsed our presentations twice in front of the lab. Many revisions were made, and I'm feeling much more prepared for the real deal. Thank you to everybody who was willing to listen to four lame high school presentations about the same topic in the same day. Your contribution will make the very same presentations significantly less lame on Thursday. Apart from presentation-related stuff, Ron and I ran some ladder network and SMCAE experiments all day. Ron tackled the ladder network with PELU activation (which was apparently very difficult) and I continued with adjusting initial layer sizes on the ladder network and doing SMCAE runs with fixed component count PCA as a feature scaler. The results aren't looking too hot, but I'll withhold judgem
