Deep dives
The Bayesians' Identity
The Bayesians represent a passionate group within machine learning that stems from statistical traditions. They perceive their approach as the most valid, believing that if something isn’t Bayesian, it is fundamentally flawed. This contrasts with the larger frequentist school that has dominated statistics over the past century, leading to a sense of being an oppressed minority. Central to their identity is the differing definition of probability, which the Bayesians assert is subjective, depending on individual beliefs rather than purely objective frequencies.
