Forward chaining (or forward reasoning) is one of the two main methods of reasoning when using an inference engine and can be described logically as repeated application of modus ponens. Forward chaining is a popular implementation strategy for expert systems, business and production rule systems. The opposite of forward chaining is backward ...
futures (forecasting, forward thinking, prospectives), planning (strategic analysis, priority setting), and; networking (participatory, dialogic) tools and orientations. Much futurology research has been rather ivory tower work, but Foresight programmes were designed to influence policy - often R&D policy. Much technology policy had been very ...
the perfectionist all-or-nothing method, with no attempt at holding partial successes. This would be expected to take more than 10^301 seconds, [i.e., 2^1000 seconds, or 3·5×(10^291) centuries] a serial-test of switches, holding on to the partial successes (assuming that these are manifest), which would take 500 seconds on average
The main approaches for stepwise regression are: Forward selection, which involves starting with no variables in the model, testing the addition of each variable using a chosen model fit criterion, adding the variable (if any) whose inclusion gives the most statistically significant improvement of the fit, and repeating this process until none improves the model to a statistically significant ...
The book's main thesis is a differentiation between two modes of thought: "System 1" is fast, instinctive and emotional; "System 2" is slower, more deliberative, and more logical. The book delineates rational and non-rational motivations or triggers associated with each type of thinking process, and how they complement each other, starting with ...
The history of scientific method considers changes in the methodology of scientific inquiry, not the history of science itself. The development of rules for scientific reasoning has not been straightforward; scientific method has been the subject of intense and recurring debate throughout the history of science, and eminent natural philosophers and scientists have argued for the primacy of ...
[2]: 13 In later writings, Cabrera describes D, S, R, and P as "patterns of thinking", and expands upon the implications of these thinking skills. [ 3 ] [ 4 ] The DSRP theory is a mathematical formalism of systems thinking and cognition , built on the philosophical underpinnings of constructivism and evolutionary epistemology .
In fact, there is evidence of some confusion about what the term ‘Theory of Change’ actually means; in some cases, what some program developers describe as a Theory of Change is, in essence, simply a log frame, strategic plan or another approach that does not encompass the complexity of the Theory of Change approach. There is also ...
