One might imagine the demands of producing such a service require some form of labelling (either exhaustively by hand or for a classifier). However wouldn’t it be cool if we could infer the splits without any labelling labour at all? …

101 Recap

  1. “Probability and statistical inference have inverse objectives”

With probability modelling we set the parameters for a specified model and simulate potential outcomes. Statistical inference on the other hand ingests measurements from the world and backtracks to estimate the parameters of a chosen model.

The bidirectional relationship underpins the way we validate statistical techniques’ potential to capture the essence of reality: we synthesise data from a known…
