Meta-Dendral is a machine learning system that receives ecpert 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.

Dendral – Wikipedia

Dendral, as their expert system was later known, was…. The name Dendral is an acronym of the term “Dendritic Algorithm”.

Internet URLs are the best. The DENDRAL Project was one of the first large-scale programs to embody the strategy of using detailed, task-specific knowledge about a problem domain as a source of heuristics, and to seek generality through automating the acquisition of such knowledge.

Also around the mid 20th century, science, especially biology, faced a fast-increasing need to develop a “man-computer expett, to aid scientists in solving problems.

Discover some of the most interesting and trending topics of The Introduction of Computers to Biology and Medicine” Buchanan wanted the system Dendral to make discoveries on its own, not just help humans make them”.

Moreover, the team was able to prove mathematically that the generator is complete, in that it produces all graphs with the specified nodes and edges, and that it is non-redundant, in that the output contains no equivalent graphs e.

Dendral Search for additional papers on this topic. There are many other programs today for solving the mass spectrometry inverse problem, see List of mass spectrometry softwarebut they are no longer described as ‘artificial intelligence’, just as structure searchers.

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