In probability theory , a martingale is a sequence of random variables (i.e., a stochastic process ) for which, at a particular time, the conditional expectation of the next value in the sequence is equal to the present value, regardless of all prior values.
Originally, martingale referred to a class of betting strate... | https://en.wikipedia.org/wiki/Martingale_(probability_theory) |
In probability theory , the martingale representation theorem states that a random variable with finite variance that is measurable with respect to the filtration generated by a Brownian motion can be written in terms of an Itô integral with respect to this Brownian motion.
The theorem only asserts the existence of th... | https://en.wikipedia.org/wiki/Martingale_representation_theorem |
Martinotti cells are small multipolar neurons with short branching dendrites . They are scattered throughout various layers of the cerebral cortex, sending their axons up to the cortical layer I where they form axonal arborization. The arbors transgress multiple columns in layer VI and make contacts with the distal tu... | https://en.wikipedia.org/wiki/Martinotti_cell |
