283 results about "Scoring rule" patented technology

In decision theory, a score function, or scoring rule, measures the accuracy of probabilistic predictions. It is applicable to tasks in which predictions must assign probabilities to a set of mutually exclusive outcomes. The set of possible outcomes can be either binary or categorical in nature, and the probabilities assigned to this set of outcomes must sum to one (where each individual probability is in the range of 0 to 1). A score can be thought of as either a measure of the "calibration" of a set of probabilistic predictions, or as a "cost function" or "loss function".

The invention relates to an oil reservoir endogenous microorganism high-efficient activator and an effect evaluation method thereof. The method comprises: the evaluation of activator components based on the economic and technical feasibility of the application of the activator; the evaluation of the activation effect of the activator based on the selective activation of oil reservoir endogenous microorganisms, the changes of biochemical indexes of oil and water samples, and the extent of the improvement of the crude oil recovery efficiency by physical simulation oil displacement experiments; the construction of detailed scoring rules of the activator and its effect with respect to the economic and technical feasibility, the selective activation of endogenous microorganisms, the biochemical indexes of oil and water samples, and physical simulation oil displacement; the construction of grade division methods of the activator and its effect based on the scoring conditions of each index. The evaluation method of the invention has the advantages of systemic and comprehensive evaluation indexes, low operation cost, and subsequent referential evaluation indexes, solves the current problems of the lack of an oil reservoir endogenous microorganism high-efficient activator and its standardized evaluation method, and provides an systemic and effective evaluation method for the smooth oil field application of the oil reservoir endogenous microorganism high-efficient activator.
