Management and Future Technologies journal.umft.uz АЛГОРИТМЫ ВОССТАНОВ ЛЕНИЯ ГЕОЛОГИЧЕСКИХ СИГНАЛОВ С ПОМОЩЬЮ СПЛАЙНОВ А ннотация: в статье обсуждается, как использовать сплайн-функции для геологических сигналов, и предлагаются алгоритмы параметризации сплайнов. Для этого возьмем в качестве примера трехточечный вынос, работающий режиме реального времени. Уникальность этих формул заключается в независимости значения оцениваемого сплайна на этом участке. Ключевые слова: сплайн, базисный сплайн, аппроксимация, b -коэффициенты, «точечные» формулы, приближения, полиномы Ньютона, алгоритм.

For this purpose, we take a three-point offset operating in real time as an example. The uniqueness of these formulas lies in the independence of the estimated spline value in this section. Keywords: spline, basis spline, approximation, b-coefficients, “point” formulas, approximations, Newton polynomials, algorithm. 73
