The phrase "approach requires only" is correct and usable in written English.
It can be used when discussing a method or strategy that needs minimal resources or conditions to be effective.
Example: "This approach requires only a basic understanding of the principles involved to be successful."
Alternatives: "method needs just" or "strategy calls for merely".
The proposed approach requires only sparely sampled data.
Also, the CAWF approach requires only one pass over the data.
Our approach requires only structural similarities as the input to predict DDIs.
Our approach requires only a minimal training set of 10 to 20 images.
The approach requires only limited experimental data and thus allows for systematic parameter studies.
The proposed approach requires only accurately measured product temperature profiles, easily obtained in a laboratory dryer.
This approach required only standard digital photographs and ground control points, took only ∼30 min in the field, and can be embedded within existing protocols easily.
A boundary value problem is formulated with respect to a warping function and solved employing a pure BEM approach requiring only a boundary discretization.
Hence, a non-iterative Primal-Dual Interior Point Method (PDIPM) based OPF approach, requiring only one common pre-contingency Hessian factorization in all the critical contingencies, is proposed for fast identification of infeasible outages.
For distributed and concentrated follower loads acting on a cantilevered beam, the method amounts to a direct solution approach requiring only a single shot (zero iterations) to compute the equilibria.
Given that mental health services are unavailable or underfunded in many countries [35], this computational approach, requiring only patients' digital consent to share their social media histories, may open avenues to care which are currently difficult or impossible to provide.
