Why is team work so difficult? Communication overhead. Consider the following teams: • Communication channels grow exponentially with the number of team members. • This typically slows down projects – " the fallacy of saving a project by adding team members " • Difficult to communicate all the technical details which come with a non-trivial project.

. Ensemble Kalman inversion (EKI) is a technique for the numerical solution of inverse problems. A great advantage of the EKI’s ensemble approach is that derivatives are not required in its implementation. But theo-retically speaking, EKI’s ensemble size needs to surpass the dimension of the problem. This is because of EKI’s “subspace property”, i.e., that the EKI solution is a linear combination of the initial ensemble it starts off with. We show that the ensemble can break out of this initial subspace when “localization” is applied. In essence, localization enforces an assumed correlation structure onto the problem, and is heavily used in ensemble Kalman filtering and data assimilation. We describe and analyze how to apply localization to the EKI, and how localization helps the EKI ensemble break out of the initial subspace. Specifically, we show that the localized EKI (LEKI) ensemble will collapse to a single point (as intended) and that the LEKI ensemble mean will converge to the global optimum at a sublinear rate. Under strict assumptions on the localization procedure and observation process, we further show that the data misfit decays uniformly. We illustrate our ideas and theoretical developments with numerical examples with simplified toy problems, a Lorenz model, and an inversion of electromagnetic data, where some of our mathematical assump- tions may only be approximately valid.

The organization works with marginalized communities in the areas of economic and social empowerment using a participatory approach aimed at helping people fight poverty and vulnerability. The Hand in Hand enterprise and job creation approach is based on a philosophy of self-help, providing training, skills and support to enable people living in poverty, particularly women, to build and sustain independent, market-based, economic activities. This provides for a higher level of income for them and their families, which in turn contributes to greater food security, better education for children, increased access to healthcare, improved housing and overall improved livelihoods.
