NRI attempts to quantify how well a new model correctly reclassifies subjects. Typically this comparison is between an original model (e.g. hip fractures as a function age and sex) and a new model which is the original model plus one additional component (e.g. hip fractures as a function of age, sex, and a genetic or proteomic biomarker).
Amongst the collection of tools, the Rushmore Drilling Index and Rushmore Drilling Index & Estimated Drilling Days, both designed and owned by the company, are particularly noteworthy. Designed as objective tools for well planning, they index the difficulty and indicate the amount of time a planned well is likely to take to drill to target depth.
The difficulty measure is related to the difficulty of the program to write or understand, e.g. when doing code review. The effort measure translates into actual coding time using the following relation,
The game tree size is the total number of possible games that can be played. This is the number of leaf nodes in the game tree rooted at the game's initial position.. The game tree is typically vastly larger than the state-space because the same positions can occur in many games by making moves in a different order (for example, in a tic-tac-toe game with two X and one O on the board, this ...
One of seven parameters used to calculate a SARI score. The Simplified Airway Risk Index (SARI), or El-Ganzouri Risk Index (EGRI), is a multivariate risk score thought to estimate the risk of difficult tracheal intubation. The SARI score ranges from 0 to 12 points, where a higher number of points indicates a more difficult airway.
Importantly, though increases in task difficulty may increase learning potential, increased task difficulty is also expected to decrease performance. Thus, an optimal challenge point exists when learning is maximized and detriment to performance in practice is minimized.
Last updated Dec. 19. Learn more about homebuying difficulty in most U.S. counties based on factors such as affordability, available homes, homebuying competition and economic stability.
Dynamic game difficulty balancing (DGDB), also known as dynamic difficulty adjustment (DDA), adaptive difficulty or dynamic game balancing (DGB), is the process of automatically changing parameters, scenarios, and behaviors in a video game in real-time, based on the player's ability, in order to avoid making the player bored (if the game is too easy) or frustrated (if it is too hard).
