## Fusion of High-quality and low-quality classification models
### Graphical models
##### An alternative formulation
### Panel A - (the most basic) model formulation (with classical ARD priors)
The model for high quality data classification follows a regression form with ARD priors. The low-quality model is trained by marginalising over the posterior distribution of the high quality coefficients $`\mathbf{w}^{H}`$ to give (the distribution of) a set of low-quality coefficients (with ARD priors likewise).

And we compared three methods:
- Blue: High + Low training
- Red: trained on low quality data
- Blue: using posterior of w (trained on the high) as priors for the low-quality data.
- Red: trained on low quality data only
- Orange: Lasso Logistic regression.
- Pale blue: trained on low quality data (marginalising over the posterior of w from high)
