TreeLas¶
This is the documentation of the C++ part of TreeLas. For the Julia documentation see here.
This is a fused Lasso Solver for tree graphs, i.e. we aim to minimize the following objective function
\[f(x) = \frac{1}{2} \sum_{i=1}^n \mu_i (x_i - y_i)^2 + \sum_{(i,j) \in E} \lambda_{ij} |x_i - x_j|\]
- Hereby is
- \(y_i\) the input signal for node \(i\),
- \(\mu_i \geq 0\) is the node weight for node \(i\),
- \(E\) the edges, usually from a tree, and
- \(\lambda_{ij} > 0\) is the edge weight for \((i,j)\).
