I know regular expressions

About 12 years ago, I learned regular expressions (also learned regular language in undergrad automata class). I'm just so proud of myself everytime I use complicated replacements. I think everybody should learn it. At least, I won't say everybody should learn vim.

5ms vs 2ms with Silverman's rule

Averaged squared Hellinger divergence computed for the same dataset, just different kernel sizes.

Uncoupled oscillators

Can uncoupled oscillators with common input and output process information? For example, audio filter banks are constructed in similar manner. Each frequency components are separately processed and then combined at the end. The key is the phase distribution in case of oscillators. That's all they have. But individual oscillators can only see their own one. What type of interaction between the input and individual phase would make this a useful computational device or memory device?

Inter trial stationarity

When conducting multiple trials of an experiment, we hope to be able to assume that the trials are independent of each other and the experimental conditions are stationary. But how can we show this? Some sort of statistical test would be nice...but that would still require independence, wouldn't it? So many things to assume to release a little bit of assumption. What an irony.
