decision stream (plural decision streams)

  1. A directed acyclic graph of decision rules generated by a statistically-based supervised learning technique or other automated procedure.
    • 1973, Nicolai Siemens, C. H. Marting, Frank Greenwood, Operations Research, page 424:
      After the scheduler has been utilized, the user may again enter the decision stream and decide whether to repeat the optimization process or terminate with a simulation.
    • 2000, Andrew G. Tescher, Applications of Digital Image Processing XXIII, page 372:
      For each tree-terminating test (every 8 decision coding words) , the number of decision coding words, bit level and number of LSP is stored. The full decision stream and list of significant pixels are stored.
    • 2019, Jyotsna Kumar Mandal, Debika Bhattacharya, Emerging Technology in Modelling and Graphics:
      This method actually constructs a sequential decision stream-based model on actual values of features in the dataset.
  2. (Can we clean up(+) this sense?) A supervised machine learning technique providing classification with recursive execution of two procedures: partitioning data into statistically different samples and merging the samples which are similar according to the test statistics.
  3. Used other than figuratively or idiomatically: see decision,‎ stream; a sequence of linked decisions.
    • 2012, Donald Palmer, Normal Organizational Wrongdoing, page 104:
      First, I contend that the process through which people become involved in unethical behavior (and by extension wrongful behavior) often consists of a stream of linked decisions, with the early decisions in a decision stream being linked to subsequent decisions by the consequences that they produce.
    • 2016, Diane Vaughan, The Challenger Launch Decision, page 247:
      The first decision in a decision stream does not survive as a precedent unless the original decision is validated by its outcome and by the outcomes of subsequent decisions. So the decision stream feeds back into that first decision, determining its continuation. For the working engineers, two decision streams contributed to the persistence of the work group's cultural construction of risk, transforming that first collection of practices and belifs into a paradigmatic prcedent: (1) FRRs for individual launches and (2) cumulative decision making for all launches.
    • 2019, Irene S. Rubin, The Politics of Public Budgeting:
      Describing each decision stream separately tends to emphasize their independence.
