Choices are made as we step down the garden of forking paths in the course of any analysis. Often, in the process of frantic search we cling too strongly to the first…

Heuristics in Latent Space: VAEs and Bayesian Inference

pytorch
variational auto-encoders
amortized bayesian inference
Missing data imposes two costs: the expense of collecting new observations and the risk of distorting the underlying structure when we construct plausible replacements. In job satisfaction surveys, non-response patterns can conceal meaningful latent relationships. This study compares statistical and machine learning approaches for imputation, focusing on their ability to preserve these latent structures while producing realistic reconstructions.

GAMs and GPs: Flexibility and Calibration

probability
generalised additive models
gaussian processes
Flexible Spline models risk overfit and need to be carefully calibrated against real data. Hierarchical models impose structure and aid calibration. We combine them.
