Dendral – Wikipedia

Topics Discussed in This Paper. BeavisBrian T Chait Analytical chemistry Symbol-processing theories and the SOAR architecture. Meta-Dendral is a machine learning system that receives the set of possible chemical structures and corresponding mass spectra as input, and proposes a set of rules of mass spectrometry that correlate structural features with processes that produce the mass spectrum. Thus, a program that is able to reduce this number of candidate solutions through the process of hypothesis formation is sytsem.

Karp AI Magazine Its primary aim was to study hypothesis formation and discovery in science.

Thank you for your feedback. MartinRichard J. A heuristic is a rule of thumb, an algorithm that does not guarantee a solution, but reduces the number of possible solutions by discarding unlikely and irrelevant solutions. It was useful to chemists as a stand-alone program to generate chemical graphs showing a complete list of structures that satisfy the constraints specified by a user.

Contact our editors with your feedback. The software program Dendral is considered the first expert system because it automated the decision-making process and problem-solving behavior of organic chemists.

There are many other programs today for solving the mass spectrometry inverse problem, see List of mass spectrometry softwarebut they are no longer experg as ‘artificial intelligence’, just as structure searchers.

Dendral then was still very inaccurate in assessing spectra of ketonesalcoholsand isomers of chemical compounds.

Simon said vendral The Sciences of the Artificial”if you take a heuristic conclusion as certain, you may be fooled and disappointed; but if you neglect heuristic conclusions altogether you will make no progress at all.
