       abstract = "This manuscript introduces a new approach for increasing the efficiency of
         automatic differentiation (AD) computations for estimating the first order derivatives comprising
         the Jacobian matrix of a complex large-scale computational model. The objective is to approximate
         the entire Jacobian matrix with minimized computational and storage resources. This is achieved by
         finding low rank approximations to a Jacobian matrix via the Efficient Subspace Method (ESM). Low
         rank Jacobian matrices arise in many of today's important scientific and engineering problems,
         e.g. nuclear reactor calculations, weather climate modeling, geophysical applications, etc. A low
         rank approximation replaces the original Jacobian matrix $J$ (whose size is dictated by the size of
         the input and output data streams) with matrices of much smaller dimensions (determined by the
         numerical rank of the Jacobian matrix). This process reveals the rank of the Jacobian matrix and can
         be obtained by ESM via a series of r randomized matrix-vector products of the form: $Jq$, and $J^{T}
         \omega$ which can be evaluated by the AD forward and reverse modes, respectively.",
