(high precision) panels, the posterior inference closely follows the 
likelihood (it “overfits”) after five time steps and the inferred heart 
rate is slightly biased (i.e. it is 79). Differently, in the right (low 
precision) panels, the inference converges much slower to a high 
precision posterior, but without overfitting.
These simple examples of Bayesian inference illustrate two 
things. First, sensory observations that are unpredictable given
