Landweber iteration

Landweber iteration is a method used to solve equations where you want to find an input that produces a specific output through a process or system, often with noisy or incomplete data. It starts with an initial guess and repeatedly refines it by measuring how far the current estimate's output is from the desired result, then adjusting the guess accordingly. This iterative approach gradually converges toward the solution, making it useful in fields like image reconstruction and signal processing to recover original data from indirect measurements.
