Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely:  present a new algorithmic approach to the group fused lasso, a convex model that approximates a multi-dimensional signal via an approximately piecewise-constant signal. This model has found many applications in multiple change point detection, signal compression, and total variation denoising, though existing algorithms typically using first-order or alternating minimization schemes.   instead develop a specialized projected Newton method, combined with a primal active set approach, which  show to be substantially faster that existing methods. Furthermore,  present two applications that use this algorithm as a fast subroutine for a more complex outer loop: segmenting linear regression models for time series data, and color image denoising.  show that on these problems the proposed method performs very ll, solving the problems faster than state-of-the-art methods and to higher accuracy.
