# Inference from Fragments **Domain:** Scientific Method / Reconstruction **Doc Type:** Cross-Domain Concept Node **Maturity:** Developed **Primary Source:** [[articles/The Art is Long|The Art is Long: Vespucci of Immortality]] **Related:** [[wiki/Recoverability|Recoverability]], [[wiki/Paleontology|Paleontology]], [[wiki/Human Genome Assembly|Human Genome Assembly]], [[wiki/DENDRAL|DENDRAL]] --- ## Definition **Inference from fragments** is the reconstruction of an absent whole, prior state, or causal structure from incomplete and noisy remains. ## Cross-Domain Pattern - Fossils constrain a model of an extinct organism. - Present sequences constrain ancestral genomes and lineages. - Short sequencing reads constrain an assembled genome. - Mass-spectrometry fragments constrain a parent molecule. - Neural measurements constrain a latent dynamical state. The epistemic question is always the same: which residual information is sufficient, and what uncertainty remains after reconstruction?
