WebFast-and-frugal trees have been found to be particularly effective in medical decision-making. In one study, doctors were asked to make decisions about whether or not to … In the study of decision-making, a fast-and-frugal tree is a simple graphical structure that categorizes objects by asking one question at a time. These decision trees are used in a range of fields: psychology, artificial intelligence, and management science. Unlike other decision or classification trees, … See more Construction The basic elements are the cues. The cues are ranked, with one cue at each level of the tree and an exit node at each level (except for two exit nodes for the last cue at the last level … See more In 2024, Phillips, Neth, Woike and Gaissmaier introduced the R package FFTrees, hosted on CRAN (with an accompanying app), which constructs, depicts graphically, … See more There have been many applications of fast-and-frugal trees in both prescribing how a decision should be made and describing how … See more
WebFast-and-frugal trees have been found to be particularly effective in medical decision-making.

WebFast-and-frugal trees were defined by Martignon and colleagues as decision trees with exactly two branches extending from each node, where either one or both branches is an exit branch leading to a leaf (Martignon et al., 2008, 2003). In other words, in an FFT one answer (or in the case of the final node, both answers) to every question posed ... WebSep 24, 2024 · Fast-and-frugal trees (FFTrees), which are simple prediction algorithms, may be useful in this context. We compared the capacity of simple FFTrees with two more complex models-namely, unconstrained classification trees (UDTs) and logistic regression (LogReg)-for the prediction of POD among older surgical patients in the perioperative …
