DENDRAL: A Case Study of the First Expert System for Scientific Hypothesis Formation

A heuristic is a rule of thumb, an algorithm that does not guarantee a solution, but reduces the number of possible solutions by discarding edndral and irrelevant solutions.

Thank You for Your Contribution! Meta-Dendral was a model for knowledge-rich learning systems that was later codified in Tom Mitchell’s influential Version Space Model of learning. Citations Publications citing this paper.

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, sendral that it is non-redundant, in that the output contains no equivalent graphs e.

Images and inference Robert K. 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 systtem processes that produce the mass spectrum.

Dendral – Wikipedia

Case Study in Generality and Problem Solving. The plan-generate-test paradigm is the basic organization of systen problem-solving method, and is a common paradigm used by both Heuristic Dendral and Meta-Dendral systems. For that, a specific task in science was chosen: During the mid 20th century, the question “can machines think? Heuristic Dendral is a program that uses mass spectra or other experimental data together with knowledge base of chemistry, to produce a set of possible chemical structures that may be responsible for producing the data.

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

The term is frequently applied to the project of developing systems endowed with the intellectual processes characteristic of humans, such as the ability to reason, discover meaning, generalize, or learn…. The name Dendral is an acronym of the term “Dendritic Algorithm”. Thus, a program that is able to reduce this number of candidate solutions through the process of hypothesis formation is sysgem.
