Made Better in Japan
The concept of tiny restaurants that rely on personal interaction is firmly rooted in Japanese tradition. So, what’s special about what’s happening at a place like Quintessence? Like many chefs in Japan, Kishida traveled to France to apprentice and spent years there perfecting his craft.
According to almost every non-Japanese chef I’ve spoken to, Japanese chefs, even those...

I was at Jingu Stadium that day, alone in the outfield drinking beer and watching the game. Jingu Stadium was within walking distance of my apartment at the time, and I was a fairly big Yakult Swallows fan. It was a perfectly beautiful spring day, not a cloud in...

Quantifying reflexivity in financial markets:... →
We introduce a new measure of activity of financial markets that provides a direct access to their level of endogeneity. This measure quantifies how much of price changes are due to endogenous feedback processes, as opposed to exogenous news. For this, we calibrate the self-excited conditional Poisson Hawkes model, which combines in a natural and parsimonious way exogenous influences with...

It is commonly believed that with aging comes an inevitable decline from vitality to frailty. This includes feeling weak and often the loss of independence. These declines may have more to do with lifestyle choices, including sedentary living and poor nutrition, than the absolute potential of musculoskeletal aging. In this study, we sought to eliminate the confounding variables of sedentary...

Estimating the bias of a noisy coin →
arxiv-math:
Authors: Christopher Ferrie, Robin Blume-Kohout
Optimal estimation of a coin’s bias using noisy data is surprisingly different from the same problem with noiseless data. We study this problem using entropy risk to quantify estimators’ accuracy. We generalize the “add Beta” estimators that work well for noiseless coins, and we find that these hedged maximum-likelihood (HML)...
