## Assume low-quality data is rotated (noiser) version of high quality data
We assume that low-quality data is rotated (noiser) version of high quality data, and to find the coefficients for low-quality data, we want to find a transformation matrix $`\mathbf{U}`$ to be applied to the low-quality data, s.t., $`\mathbf{U}^{T}\mathbf{U} = \mathbf{I}`$.
The posterior of $`\mathbf{U}`$ is
```math
P(\mathbf{U}|\mathbf{t}, \mathbf{H}^{L}, \mathbf{w}, \beta_1,...\beta_d) \propto P(\mathbf{t}|\mathbf{X}^{L},\mathbf{U}, \mathbf{w})P(\mathbf{U} | \mathbf{w}, \beta_1,...\beta_d)
```
