Recently, I posted the article about the frequency estimation with differential equation (a translation from my Japanese article). I think it is interesting that a signal processing problem of frequency estimation reduces to solving an algebraic equation. tam5917.hatenablog.com/entry/2025/0...

KLR/KRR can be considered as replacing the Hopfield network's recollection rules with those that have high pattern separation ability using kernel methods.

Based on the two kernel method papers that I previously uploaded as preprints, it looks like I will be able to tackle many more research topics.

I've been concerned about the impact of generative AI on the field of education. I teach programming classes, and there are many difficult aspects to it.

Presenting at an international conference abroad is good, but I also think it would be better to stay in the own country and submit and present a journal article. The former is financially expensive and can make you sick.
