July 15: Handiball Victory!
Bleagh... Yesterday I didn't get to sleep until after 2:30AM. >_< I was rather tired for most of the morning as a result, but I did end up getting to work on time. I ate dorm breakfast of stewed ground beef and cabbage with chikuwa stuffed with cucumbers and green peppers. I quite liked all of it (including the miso soup and rice haha).
At work I set about deriving the important equations for using Collapsed Gibbs Sampling in my mixture model properly. It was relatively straightforward, but it takes quite a while because I want to be as careful as possible. I showed my work to Kabutoya-san and he had some minor adjustments to make (mostly notational, as the paper that I was working from uses the world's crappiest notation), but on the whole my derivation passed inspection.
At lunch I ate Hiyashi ramen, which is good, but their broth is always too salty! I think I have quite enough salt in my diet already without all the extra added unnecessarily into the broth. I can understand what Kabutoya-san and co. mean when they complain about the cafeteria a little bit more now, as I've been mimicking what they're eating a little bit of late. I do find it strange, however, that they appear to choose the foods that I have found the cafeteria to do the most poorly. >_<
After eating I played handiball, and I was alright but not great, and unfortunately my serve was horrid today. There was quite a crowd at the handiball court today, which was kind of fun due to raucous observers aplenty.
In the afternoon I coded my CGS mixture model recommender, and I actually managed to "complete" it at around 5pm, starting from about 2:30 (I had some more stuff to ask Kabutoya-san, who was away from his desk for quite a while, so I read up on some relevant concepts on Wikipedia in the meantime). "Complete" is in quotation marks, because currently it doesn't work. I dunno man, 0.0/infinity sounds like a perfectly reasonable value for a probability to me. >_< I guess I'll find out tomorrow what that's about haha...
At 5:30 I had my second formal handiball game! Our team has about 9 players on it, so I only play for about half the time. I served really, really poorly today, which was really annoying because that's kind of my selling feature, by my own evaluation. I at least was able to contribute in other ways though, as my average-for-North-America height is a rather unfair advantage. >_< Our team ended up winning 2-0, which is doubly nice, as Kabutoya-san said that the other team is actually an alright team.
After the game I went back to my desk and made as little noise as possible while working, and I was able to stay until about 6:40 before Kabutoya-san remembered to kick me out hahah. Damnit! I wanted to get my recommender to a state at least somewhat resembling operational on the first day (just for pride's sake), but it wasn't in the stars. D: I walked home, and it was quite pleasant, because I was still in my short and T-shirt from volleyball. Did you know slacks are not the best possible wear for walking up and down hills? ;D
I got home and had dorm supper of tofu with a green onion, shiso and tiny crustacean (shrimpy things, possibly krill?) topping, as well as some rather bland chicken on rice (with miso soup). I quite liked the tofu thing, as it was cool and very slightly salty and had a very strong shiso flavour, all of which are perfect for summer (when I got back to my room from work the thermometer on my clock read at slightly above 33C, ew).
Oh, today I found out that I have Monday off! Turns out it's "Sea Day", which is a holiday for the Emperor's birthday. I wonder what I'll do for it... ;D I actually did ask Nishida-san if there are any actual celebrations for Sea Day, but he said that there isn't much (and nothing traditional, certainly), as the holiday is new, and will disappear when there's a new Emperor with a different birthday.
I'd best go to bed soon to avoid falling further behind in sleep. Night!
