Tensor theory is deep. It’s one of those areas that’s much more complicated than it needs to be. The good news is that I can still pick the fundamentals up within an hour and it’s going to enable me to write a lot of background if I want to (I’m thinking around a 35 page background section is sufficient, leaving me around 80 or 90 for methodology and the remainder for other sections and appendices). I’m done talking about SVD and its equivalents, but now I get to mention PCA, ICA, and LSI! 🙂

I wanted to perform an actual experiment this week and get started on the methodology, but unfortunately, I don’t understand how our data is formatted and the only one who can explain it to me isn’t around when I am until next Tuesday, so that is going to have to wait.

I’ve written 4.5 pages so far; 6 left to meet the weekly goal. It may all be background, but I can do it if I take tomorrow and maybe Saturday to write.

And Einstein notation? I admire Einstein as much as the next guy, but that’s a pretty stupid idea, honestly, whether Einstein introduced it or not. Think about it: not only are you summing without using a + or summation symbol, but you’re now using both subscripts and superscripts to describe things that are not true indices or exponents. I certainly don’t think I’ll be using it in my dissertation.
