Figure 2
From: Quantification of expected information gain in visual acuity and contrast sensitivity tests
An illustration of expected information gain from measurement of the length of pencils using a ruler with unit \(\Delta\). (a) A uniformly distributed pencil length \(X\), \(P\left(x\right)\). (b) Outcome distribution from measuring the length of a pencil with true length \({x}_{0}\), P \(\left(y|{x}_{0}\right)\). (c) A uniformly distributed outcomes \(Y\), \(P\left(y\right).\) (d) Posterior distribution of \(x\) based on measurement outcome \({y}_{0}, P(x|{y}_{0}).\)
